What's the point? I learned how to grow from this forum and I am grateful for the help over the years.However this name calling and arguing is not helping anyone and I will look elsewhere for help in the future. All the best and keep on growing. Twisted.

The 5 pack was a freebie pack. I Suppose thats why they're free. They weren't over stressed either, Conditions were proper.


Comments

Hey guys... I'm asking these questions to help assess my methods to see if I am close to what you are acheiving: About what height are your plants when you put them into bloom? (I will need to know that.) How long does it take you to get them to that height? From one of those plants, what is your average yield? I know that you, Mark, prefer an indica for your health conditions so I'm assumming your answers will be based on those. If, however, you have the same info on how your sativas do also that would be amazing. Thank you very much for all the help.


Comments

Hey Jaded..you too are a complete ass hole.


Comments

Hey everybody..PLEASE..this is a grow forum..everyone is entitled to their opinion...this is just not a appropriate place for politics or religion ..try Cannabis Culture or Passion ...Mark will have his computer up and running any day now....and will be back to the grow Q's. Thanks and Best Health to all....


Comments

Ah Jaded, did I hurt your feelings? Poor little boy... Did you think people could not recognize that it was you adding those other posts, you know, like "you are not welcome here?" Did you honestly think we wouldn't know? I'm sure it was difficult for that confused little brain of yours to come up with such an ingenious 'trick,' but fear not, we are all praying for you. Now post away if you must, this is my last about this subject because I have more repect for Mark, Dan and the others here than to continue on. P.S. Religious the prayer was not. Someday, perhaps when your cracked head heals, if that's possible, you'll understand.


Comments

Jack you are most likely STRESSING your plants out to much.[.PEOPLE ..please actually READ the grow guide..90% of all these q's are ANSWERED there!!!!..STOP being so lazy and read a bit....] ........... there are MANY ways you can stress plants feminized or not..into Hermies.....I would think this might be the cause of such a high percentage of switch overs....but I bet you Mark will still offer you a complete refund/replacement..he is just about the kindest dude anyware.


Comments

Again to all you people who think that THIS IS A BUSINESS TO MAKE MONEY>>>GO AWAY it is not!!!!!!!!!...if you had any Idea ANY FREAKIN IDEA..how much this man MARK X does for the community, the people....the cause of the legal system..which of course he is in because the gov't does not want people to feel better you would feel like the biggest jerk ever....oh ya you are probably NOT intelligent enough. Mark X IS NOT RICH..he barely covers his costs..and crack heads DO steal to support their crummy shit habit..death penalty for all convicted of smoking Crack.....It will be a great loss to all if mark decides to kill this site because religous freaks and cop wannabes come on this site and bitch like they are someone else....if you cannot find something better d to do with your time than complain against others who try to help others ..MOVE TO THE DAMN UNITED STATES WHERE YOU BELONG>

Hey...JERK-OFF....JADED PRAYER...this is a forum for marijauna growers and people who are looking for grow help..THIS IS NOT A FORUM FOR PHILOSOPHIC MORONS WITH SOME KIND OF ATTITUDE..Go to Cannibis Culture or something else. This is not appropriate for this site...just because YOU think to do..WHAT? be a jerk....DON"T COME BACK!!!!!!!!!!!!!! You will NOT be welcomed here>

And as the people bowed their heads for a moment of silence, Master Leader begain his prayer ... Almighty me, please help the jaded to see that hermaphrodites did not choose that lifestyle, that it was merely thrust upon them by Father Earth in a moment of indecision. Show jaded the way, tell him of Mother Earth's predisposed genetical choices, those being not three, but only two, the male and the female and how Father Earth likes to play tricks on Mother Earth to make guessing games of her children's sexuality. I beg you, Almighty, explain in simple terms to all those who are jaded, particularly one, that crack heads do exist, and that crack heads are not only those who indulge in a specific drug experience, but may simply be those with cracked heads. Oh my superior Almighty myself, allow jaded to understand that the free forum he refers to does not come with instant gratification for his every whim, desire and fantasy. Explain how "free" is a gift to him and that complaints thereto are akin to pure greed and "give me everything I want when I want it or I will take my ball and bat and go home" inspired thinking. Ah yes Almighty, the jaded is in pain and needs your help. He believes that "free" is a personal obligation to his personal self, and that those who offer free services must always put their lives on hold to satisfy him. In trust I leave this with you Almighty one, me. I know you will answer the call immediately, as the jaded need personal attention at their demand, because without such, may indeed become another with a cracked head. Amen.

Hey Mark, Don't pay attention to Jaded there. He doesn't know that you are an activist and really are doing this so people grow their own weed.

Lets observe a moment of silence for the JADED


Comments

Hi there... when you clone for sex do you put them into bloom right away or do you give the roots a chance to grow first? Which is the better method sort of thing? Thanks.


Comments

Hi these will sound stupid to most people but I dont know the answers. Some people say u cant smoke the males but most people say u can. I dont know what you smoke on them though, the flowers where the pollin comes out are really small and all spread out up the branch, is that it? Almost everyone tells me u cant smoke the leaves but if you make hash from leaves what is the differnce of smoking them?


Comments

I DON'T UNDERSTAND WHY YOU ARE SO UPSET. MARK HAS HELPED US OUT SEVERAL TIMES AND WAS VERY HELPFUL. NOT ONCE DID HE REQUEST MONEY FOR HIS ADVICE.


Comments

blame it on the crack heads,, yeah right, that clears all responsibility. getting another computer should take hours especially with all the money you make "helping" people.Potsmokers would be to lazy to steal anything, I guess you are making enough money off of "helping" people and you dont have to reply to peoples questions....as for the guy that had ALL FIVE of his seeds turn hermie.....I had the same problem of course it was "MY" fault.My suggestion .....get a clone off a friend.....this forum is free and "nothing" is free............signed, Jaded.


Comments

adding on to my question: there is a white powder like substance that forms on one of the grow plugs,do you know what that is and why it happens.when do you raise the amount of nutrients you feed your plants,how do you know...is it like every week or 2weeks or when they get a certain amount of leaves or a certain height tall.please help dont want my plants to die,how do i get plants back to a healthy green n not yellow


Comments

Grew out a 5 pack of feminised seeds. Had a problem with all 5 going herm. They were grown indoors as 2 plants, outdoors as 3 each in different spots.


Comments

mark i have 4plants that i had to leave unattended for 5day(not much light and no water)they are still standing but have now are real light in color.one plant is 23 days old 3inches tall with 5 sets of leaves,the other 3 are between 3-4inches tall with two or three sets of leaves.im using a 400 w light.the 23 day old plants had a few dead parts on like two leaves but i cut them off.i feed them 5ml of the flora series but they havent changed,is that to much or not enough,why would my oldest plant be so light and have a few dead tips on 2 of her 10 leaves,she not growing straight up,why is this happening and wat can i do to fix it,how food should thet get and how far from the light should they be.the plant with 5 sets of leaves is 9 days old then the other 3.i have bb sk and jfxnlxsk


Comments

This is a curiosity question. I think the answer is "yes" but I'd like to know for sure. Can a female be pollinated by males from 2 different strains thereby producing seeds of 2 different varieties? Obviously you wouldn't know which seed was which but ,,. I can't see any reason why not, in fact, it seems like a stupid question, but what do you say?


Comments

i had 2 good feminised strains ...super girl and snow white...(aka white widow) no complaints about the product but i thought if not polinised they werent supposed to make seeds....very few though...are the seeds feminised??


Comments

can u clone a plant that is about 1 or 2 weeks from harvest and put in veg to use as a mother plant,

I was just wondering if im growing in an appartment closet were am i sapposed to direct the air out of the closet from my home made air duct. I have cut a hole in the wall and installed a fan to suck out the air but is it ok for the air to just go in the wall ?

Mark or Dan or anyone that can help, do you know of any good anonymous web hosts for a cannabis info site? I know you have web hosting (or used to?) but to tell you the truth it is kind of expensive compared to the top rated ones. I want a host, where, if someone wants to know who runs the site they won't be able to get it. I know I don't HAVE to hide my identity but I want to anyway. If the host is more than $7.95 a month it's not worth it to me as their are amazing hosts for that amount and less. Any help would be appreciated a LOT.

Every now and then Mother Nature plays a dirty trick and gives me a seedling that grows incredibly slowly. They're always healthy, just smaller than the rest 'cause of the SLOW growth rate and usually never get very big unless you leave them in veg for, well, a LONG time. I'm sure this must happen to everyone and must be rooted in genetics, but, has anyone ever heard of a way to stimulate these slow movers or something along that line? Is it something we just have to live with or has something been tried to help this lil' ones along? Thanks.

I have two questions; if you use promix what should you germinate your seeds in............little pots or the plastic plant treys and then transplant to pots when they get bigger.how do you feed plants using promix.how much easier is promix over a watering system,what are the advantages and disadvantages of promix,if i cant find promix what can i use,is growing and harvesting time the same.......and my other question is if i wanted to try and grow good regular mid grade do i need nutrients and all that or do i just need soil regular water and air.what would a beginner need to grow good pop corn regular mid grade.the 1st question is for cannibus.sorry so long


Comments

hey mark,i have one seedling that is 2weeks old about 2 3/8 tall with 4 going on 5 sets of leaves.when it was a couple days old(1/2 inch tall) the hydro store told me to feed it 1/4 of the recommended nutrients.it was under a flourescent light and transplanted to a 400w hid 4days ago.just recently it starting gettin a little light green so the store told me to give the plant full strength (2.5ml) but its still light green.what should i do.if i need to add more nutrients do i need to change the water too or just add the extra nutrients to the nutrients and water already in the reservoir.i also have 3 seedling bout a week old about(2 1/2-4"tall)under the same 400w hid.i am feeding these seedlings a 1/4 of the recommended nutrients(store told me to)and they are turning a little light to,what can i do to help my little ladies


Comments

Marek, What would i need to do or what license would i need to get, if any, if i wanted to set up a small seed company similar to yours and sell the seeds online to people ONLY in Canada?


Comments

I don't think you got ripped off, Mark is an honest businessman, and he makes sure his clients are always satisfied. he might have just been busy or your order just slipped or something. Anyways I'm saying this cause Lots of people order from Mark and everyone is usually satisfied. If they're not, then Mark is fair, and does whatever needs to be done for you to be happy. Be patient dude.


Comments

Hey, I have sent various e-mails and made numerous phone calls regarding a major issue I have with my order. I have no other recourse but to attempt contact through here. The seeds I ordered did not come in the original packaging as stated online. When I sent an e-mail on Aug. 3 and got a response from Dan Aug. 15, telling me that the seeds were packed that way to "protect" them. It was agreed that this was not good a good way to ensure authentic product and an arrangement was made for replacements. On Aug. 17, I was asked to re-submit my address so I could get the seeds "ASAP" but I have yet to see anything, or even get an e-mail back. Please help me out here, I feel as if I've been forgotten or worse ripped.

Hey Mark, I have recently tried the S.O.G. method as i wanted to shorten harvest times.....me and my wife are chronics.... I am now 4 weeks into bloom 1000w hps, suneshine 4 mix. wwxxx & NL buddha. I noticed round white spots on the large fan leaves, the spots are the size of a dime, after a quick search on the internet I have determined that I have "powdery mildew" the pictures were exact to what my leafs looked like. I had to remove 18 plants.....Fuck...!!! I had stretching problems....high heat.... and the room was a jungle, I thought I have sufficient intake and exhaust...two 6" inlines. How do I get rid of this?... now that i have it is it here for good? is my crop toast? Please help Mark, I will folow your advice. Thank you in advance. P.S. If I have to start buying it for my wife I will have to mortgage the house, she is a human CHIMNEY.

I have wasted 2 Bubblelicious seeds by having them germinate. Then transfer them into 2 8" ProMix filled pots with 2 23 Watt CFBs standing over them on 18X6 timing. The the feed I use has been successful before (Miracle-Gro[All Purpose]) 24-8-16 diluted to 50% with other seeds. What seems to be happening for a second time with the Bubblelicious is that the stalk is growing tall and so thin that as soon the real leaves will grow out and tip the stalk over again. Am I missing something? This time I have put a light fan on the small plants, but I gathered from your grower's guide that this wasn't necessary until when the plant truly started sprouted leaves and you moved to the M-H lighting. What exactly causes the skinny stalks since the leafs are forming?


Comments

Quick question about bud booster. The guide says to use in 5th or 6th week, does it make much difference which? And do you do it for one week (for as many times as you water in that week), one watering, or is 2 weeks best. Coming up on that time and just wanted to clear this up to get the best results I can. Thanks a lot for all your help!


Comments

Hi Mark,I helped a friend set up a small grow in her closet with 400MH. The instructions on the bulb said if running 24 hours to turn off the bulb for fifteen minutes every two weeks. I've always have grown with HPS and have never had any problems with breakage if left on continuously.Do you bother shutting down for 15 minutes every two weeks with MH? Thanks.


Comments

Sorry, but I wouldn't use ANYTHING less than a 1000W metal halide WITH a 1000W high preasure sodium TOGETHER !!!!!!!!!!!!!!! ANYTHING less like the guy below said and your growing 50% of the yield..25% of the yield...or what ever..again sorry, folks I know there is "alot" of reasons to use 400W or 600W (...100W flourecents for beginning veg is the only thing that works) and stuff..I had living conditions were I just could not use 1000W too but its still fact...if you want to get the best yield and the best weed from any area...yagddadoit...1000W all the way........

whats the best food for them what is your yeild

What would I be expected to pay for a gram of hash on the street in TO?


Comments

I'm 3 weeks into bloom and the tips and edges of the big individual leaves are turning a really light brown colour and are curling up. Just wondering if you know whats up?


Comments

at tip for the beginners from someone who has been there and done that. saving twenty or even a hundred dollars on your lamps and ballasts is trivial in the grand scheme of things. your light is the most important component in your indoor garden. a properly designed/matched light and ballast from a hydro store is the foundation of your garden so why scrimp? it may hurt a bit when you buy the equipment but it will pay for itself ten times over on the very first harvest. always buy high quality purpose-specific stuff for your garden or else dont be suprised with poor results. it is impossible to grow good weed with mediocre lighting. period. no exceptions.


Comments

Hey guys! i though i would mention something that Trevor from Grow-it-all informed me of; that apparently you can use lower wattage bulbs in a higher wattage ballast, so i decided to try it out on my 600W HPS ballast with a 400w HPS bulb, and it worked, keep in mind you cannot use a higher wattage bulb in a lower wattage ballast. i had just learned of this but i have not seen this mentioned anywhere before, i am just wondering if Mark or Dan would know about this, and if so do you guys know if their are pros and cons of doing this? i am just glad i do not have to buy a new ballast, also Trevor told me, doing this is actually less taxing on the system so i suppose there aren't really any cons? thanks guys!!


Comments

Hey, Im an outdoor grower from 43N Ontario. I grew some BC big bud and some strawberry cough clones this year, the big bud im about to pull in 2 weeks looks delicious and the coughs still have a little while to go. after reviewing your strain list at happy girl, i was wondering what are some high yielding outdoor strains that will finish at a reasonable time for our location, im looking for a variety of high yielders as i can store and last threw the winter till next season and so on, thanks!


Comments

hey mark, back again. i was just wondering when i would know when to start harvesting one of my plants has some red hairs on the buds and has some little black things around the base of the bud generally spread around that area i was wondering what it could be i hope it was just dirt and was afraid it could be sumthing harmful so i wiped them off. this may seem like a dumb question but once you harvest i can put the plant bak into veg state right cuz they didn't really fully gorw the first time around, kind of small and frail, not bushy like the ones my friend planted in his bak yard that were of the same strain. On top of which i just wanted to say i've been on your site a lot lately studying everything(its taking a while to take it all in theres a lot to know) and u gotta keep on keepin on man it would only make sense to legalize marijuana but they will fight against it extremely hard since it will be impossible for the government to monopolize it like alcohol (LCBO) since any1 can grow in their houses.


Comments

sdlings are in grow plugs in the little plant treys that hold 6 plugs,seedlings get no nutrients,they only get watered once a day with just water.no system just me watering them.so i dont know why there dark.there stretching to,how can i get them healthy green


Comments

the mh bulbs are totally clear and they say they use a certain ballast so does it sound fine to use.should i look for tha light 2 be bright white or more blueish when turned on.how do i introduce 2wk old seedling to more light power

one of my grow plugs has like a lil white powder substance on it,do you know why that is or why it happen,will it effect sdling

hey Mark. Around June 5 a friend of mine finally was able to get me 50 guaranteed female clones for outdoor growing. I had never tried growing before but my friends entire family has been growing for years and were telling me all i had to do with these plants is find a good place by water and they will yield about 2-6 oz. each which was definately an overstatement. i was unable to check on them much hense they struggled and most of them only had one long stem and a motherbud at the top. I decided that some of the smaller/weaker plants should just be brought inside to be taken care of around september 10-20th. I transplanted two into one 14 by 14 inch pot and 3 more into 8 by 8 inch pots with only regular soil from Canadian Tire. i have them under my friends crappy fluorecent light that im not sure is even going to help them since it seems to be a bit dim/blue and i have been lightly watering them about once every 1-2days. Some of the leaves used to be yellowing when i brought them in but the larger ones are returning green but many of the smaller and lower leaves have begun to fall off. They have also already started to bud but even though i have been keeping the light on for as long as possible since they were weak i thought they needed it. I have only added an extremely small amount of all-purpose miracle gro 12-4-8 because i thought it was better than nothing and i knew it wasn't the best stuff to use for the stage they are in but its all i had available at the time. On top of which i have transplanted these plants 1- to go outside 2- to get back inside 3- into the larger pots once inside. I'm hoping that I can hopefully use some 20-20-20 and get a Metal Hallide light and they will come back strong, but i'd really like to get your advice before i do anything more.

I'm going to be running two 1000 watt hps bulbs horizontally in cylindrical tubes. Just wondering how far apart i should space the bulbs.

WEBMASTER:  ..each bulb can cover roughly 5 feet by 5 feet of space, so the bulbs should be about 5 feet apart.....

Hello. About 15 years ago I tried some really good hash. We were doing hot knifes at my buddys  place on the 17th floor and I remember the most amazing feeling when a few friends and I were coming down the stairs stoned from the 17th floor. I felt like someone picked me up by the shoulders and all I had to do was lightly move my feet and I was flying down the stairs. I will never forget this feeling. My question is: Has anyone had this kind or a similar flying sensation of a trip and what strain should I go with to make me fly again? Thanx guys.

WEBMASTER:  .... I though I was a power ranger once but they probably laced the weed with crap ....


Comments

This is from a previous post. You asked where I read that the nutrient concentration increases when the soil dries. Here's the link: http://www.cannabisculture.com/articles/1536.html Its towards the bottom where it says that the EC doubles or more once the soil dries.

WEBMASTER:  ..if you follow my guide I always stress out leaching out the promix with a low dosage of nutrients (like 25%) .. this removes the build up of salts which reads as high EC on the EC meter.... the EC they refer to is the natural build up of salts that happens more or less with different nutrients, EC measures content of salt (in water).... with Miracle Grow salts build up quickly, with a and b formula the salts are less of a problem... on a table you have a steady EC but with dirt the EC changes... EC here referring to nutrient levels..... it can be very complicated as to how to measure or interpret EC .... your best EC level (when your plants are at their best) may not be my best EC level... EC measurements are good for growers mixing large quantities of food, its just easier to do it quickly, but it should never be looked at as a reference point for sharing information.... If you tell me you have EC of 1.8 (or 1800) it means nothing to me.... if you tell me you mix 5 ml of X nutrient to get 1800 EC ... that's helpful.... the city you are in can have tap water measuring 400 (or 0.4) on the EC meter... my city (Toronto) has 0.3 as a base line... it would take me more nutrients to achieve 1.8 then you .... in promix this is not too important but in rockwool this would be a problem...


Comments

Hi Mark; I have 3 plants going all looking good except I have just noticed that a few leafs of one plant are turning a little yellow...any suggestions?...the rest of the plant is nice and green....any suggestions?

WEBMASTER:  ..if the leafs (going yellow) are on the bottom of the plant, its normal, if the yellowing leafs are all over the plant , could mean she wants more nutrients... not more often, but a larger dosage...


Comments

one more thing......the metal halide bulb box says bright white light. does that mean anything. is it still blue spectrum

WEBMASTER:  ..if its coated in white it is better to get the one that is clear.. i.e. not coated... I hope you understand that to make a 100W or a 400W bulb work you need a ballast and you can not just plug it straight into the grid without this ballast... of course, sold separately :-)


Comments

what kind of fan should i try 2 get on ebay. temp is between 77-83 f and 38-50 humidity is that fine

WEBMASTER:  .you are in the zone, humidity is ok as well.... theoretically you do not need a fan....

so even if it doesn't say blue spectrum on the box or bulb its still has to be blue spectrum if its a metal halide bulb? i know i keep asking you about bulbs but this will be the 3rd time i took back bulbs to get different ones. How many lumens will 400w MH bulb from lowes gives off. so as long as it say metal halide does it matter where i get it from: plant stores (always more expensive) vs a hardware store (always cheaper). lowes sales metal halide and high pressure sodium bulbs 100-400w.What is your take on these bulbs before i jump to conclusions and think everything is good and go buy them and if you think these bulbs are okay how do you switch plants from 100-150w fluorescent to 1 400w or 2 400w metal halide. how many bulbs would you use if 400 is highest watt mh bulb they carry..1....2... or 3.thank you, can you check on these bulbs for me like you did for the 150w coated agro plant bulbs i asked you about cause you know what bulbs are for real and which bulbs are no good to use

WEBMASTER:  ..I do not know about lowes or any other hardware store... metal halide is a metal halide, as long as its not coated with some white stuff but a clear metal halide bulb, its the same as a grow light... your street lights are in fact grow lights.... there is a reason I start teaching at 400W level because anybody growing with less power is a hobby guy and not really medical or chronic.... in other words your yield with anything less then a 400W light is a joke to me and you are on your own.... There is a reason Hydro stores exist... they already have the stuff you need... if you go out and take down the names of bulbs including brands, power and general looks (clear, white, coated, uncoated, etc.) I may help you ....

hey, i am using 2 plt/aquarium light (75w output/17w use of energy each), i have 4 seedlings. one of them is bout 13days old with 3 sets a leaves (2full and 1 set growing out) and is 2 1/4inches tall. light is 3inches away and is feed half nutrients once a day for about 15min. It looks good...a little small but what do i know im not a pro. Any suggestions or advice on that. And the other 3 seedlings are 5days old stretched a little they 2 1/4 and 3 1/2 inches tall, i had them under the same light. There top leaves are a dark green. What does that mean and what can i do about it. Im only feeding them with water that i pour over the grow plug once a day

WEBMASTER:  ..you are most likely drowning the roots and over feeding them as well, that's why they are dark green, and you most likely have burnt tips on leafs and darks stems, an early sign of overfeeding.... I do not think the plants this young under this little light can absorb this much nutrients.... I would water the grow plugs may be once a day , most likely every second day... I would not really give them nutrients unless they are already in some medium (like dirt, promix or such) .... at this point they may absorb nutrients at 10% of recommended but more will kill them.....

i have littles white spot on the leaves 2 weeks and a half old seedling it's the xxx 420

WEBMASTER:  ..? don't know....... when they are this young anything could be something or nothing... its usually nothing... in order to have a serious diagnosis I need to know a lot more about how you are doing it.... white spots could be a million thing BUT is probably nothing

Hey Mark, sorry to keep bothering you but I'm trying to do it right this time around ie. following your advice. On the topic of venting with an inline fan. I was planning to use a heating/cooling booster fan from the hardware store.. 5" Max boosted CFM 225/ Free air CFM 140. its a booster fan and not a primary fan, its very weak and cheap I must say Would I be better to vent off of the ceiling or vent off of the lamp reflector to pull away heat as it is generated ? yes, either way its fine , its the power on the fan needed that matters Again vented into chimney with 4" flexible ducting. I'm currently using a converted air cleaner as an inline fan ( see link) it probably has a low CFM rating, I'm hoping that a "real" unit will pull sufficient air out of closet to bring temps below 30/31. What's your (valued) opinion. ps are 2 instances of sucking up in the same post too much? :) thanx so much .. if I ever get to TO again I'll make it a point of stoppin by to say hi and have a tea.

WEBMASTER:  ..this is the type of fan you should have, ebay has this ..... this is the fan you could get anywhere, a squirrel fan with 275 CFM rating would be the cheapest and working alternative .... your temperatures would not budge with the set up you envision, the booster fan is too weak... its actually easier to wait for the weather to cool down...


Comments

OKKK EMERGENCY The fast pine that I have is outside looking great except that everyday im starting to notice more & more fucking holes EVERYWHERE! I looked at the underside of the leaf and nothing I examined it thoroughly and I can't see any reason for this. PLEASEEE HELPPPPP!!!!!!

WEBMASTER:  ..I am sorry but this involves a book like this .... look through the pictures and match it to the problem... most likely its a bug... slight spray with a 10 ml/L of dishwashing soap would / should do the work.... mist it rather then spray it....


Comments

Should i be trimming the leaves that grow independently? Seems like they're useless and blocking the light from the good stuff.

WEBMASTER:  ..I do not advise trimming leafs, they feed the rest of the plant.... but in veg its not lethal, in bloom it can be very bad when you remove leafs (unless they are dead and dry).... when someone talks about trimming the plants they mean trimming the branches and not primarily the leafs... removing branches that will never get light (or hang too low, are too weak, are too far away from light), ... they definitely should be removed and the plant will put more energy into the remaining branches.... even then its something you do once or twice in its life time and never again as it will stress the plant out...


Comments

I know its important to keep plants from touching (each other/walls) in veg...is it true for bloom ? Most budding grow pics I see the plants are crammed

WEBMASTER:  ..once in the 2nd week of bloom if my plants touch its ok with me.... but if the plants are already touching while in the veg period the plants get stressed out, they stretch up, and overall yield less then they could.... you see pictures of plants well into the bloom cycle... so there is a jungle in there, but notice that each and every branch has access to the light..... its about maximizing the area given not about throwing in as many plants as the you can.....


Comments

Mark, thanks for the speedy reply re chimney venting.. My concern was Co leaking out of the chimney back into the closet, however there seems to be ample air draw/flow out of the closet and up into chimney, with the fan off, when the hot water heater is actually heating or on pilot only. Closet is insulated and inside an insulated garage that is attached to the house and under a bedroom . It's difficult keeping temps down under 30'(400w HPS) can't leave door open .. kids coming & going.. but I guess given the outside temp lately you can't do much but wait for cooler weather. Growing 6 female blueberry (clones from last disastrous grow) from the up in smoke cafe. Does BB tend to be finicky about higher temps (25 night 30-31 day)? thanx

WEBMASTER:  ....the plants stretch a bit more under 31C then under 27C but it does not affect the bud too much quality wise... BB is a bit more difficult to manage, but I would not say its tricky in any way... do not overfeed her and she will be fine....


Comments

Mark..., et al...I have started a new Google group.."MMM" Medical Mary-Jane Members...for all the medical people.. discussions( conditions to most helpful strains etc..)...for anyone...please check it out and help me expand this forum...Thanks

WEBMASTER:  ..I wish you luck.... spread the word


Comments

i think I made a mistake ..when watering (feeding). It seems that the leaves go yellow if I spilled nutrients on them...I take it we SHOULD NOT do this ..so I thought I would post for others.

WEBMASTER:  ..they may get burnt from the salts in the nutrients... sometimes nothing happens, sometimes they go yellow.... the younger they are the easier they get damaged...

Hi, has anyone ever had a germinated seed with a brown root? I put 5 seeds a friend gave me in a small glass of water and 4 germinated but all have brown roots. It's really weird. Mark, Dan, anyone ever seen this before? Is it just a normal variation or are they a bunch of freaks? ;-) Thank you!

WEBMASTER:  ..I would say the roots are dying as they are developing, roots should be white, grey means trouble and brown means death... germinating cannabis seed in water is tricky, they don't like being submerged in water, they like being coated or misted at best.... transfer them quickly into another medium, rockwool or dirt .... they may recover... may..

Hello Mark. Been away from these boards for a while. I took some seeds (5 I believe...3 Juicy FruitX and 2 WWXXX) and got good germination (only one WWXXX didn't not sprout). Anyways, when I switched to bloom all but one of the Juicy Fruit crosses were male, so now I am midway through week 3 with one female (that looks amazing so far by the way). I was just wondering if 1 out of 4 is good or not. I think I've been pretty good, steady temps around 27-29C, not too much crowding, humidity maybe a tad high ranging from 40-70%. Could they have been stressed into males (they could but is not always the reason) or do you think that's just how they were (debatable, I don't think so but at the same time no one can tell from just looking at the seed) ? Not looking for any refunds or anything if this is a bad rate, just curious. Will definitely be coming back to buy more seeds in the future as I've had nothing but good service from you. Keep up the good work Mark! Thanks.

WEBMASTER:  ..I would be horrified with that ratio and the warranty always applies... but it is a bit of a gambling thing with these plants... I could go on about temperatures and such and some people can "claim" many things but the bottom line is that you can not predict the male to female ratio, like in gambling you can only improve the odds.... I've seen people pull 10 year old seeds from a basement drawer, sprouted and grew... and sophisticated and dedicated people come up with 80% males... that is why mother plants and clones are crucial to a consistent (and successful) crop....

Just a tip for those who need it ... you can buy plastic garbage pails at most dollar stores (for a buck, imagine that!) that hold 5 gallons. I like them because they are deep but still plenty wide enough and you can easily pack them together in a reasonable space if that's your growing style. Just make sure to drill some holes in the bottom and set them on something that can collect the excess water. Hope this helps. At a buck a piece it's the cheapest I can get around where I live so it's probably the same for someone else also. Cheers!

Wow I am a bone head! I had my plants in 16 ON 8 OFF for a week. They are showing signs of sex already. If I flip the lights back to 18 and 6 will they go back to veg? Please say they will

WEBMASTER:  ..they should be fine after a week of hibernation....


Comments

Thanx for all the great info. I have a 4x4 closet grow. I've vented into the natural gas hot water chimney vent about 6' above the heater using a computer fan mounted directly to the outer liner . I sealed the outer and inner liner together using foil tape. Do I need to worry about carbon monoxide leaks into the grow closet through the fan if the fan fails due to a power failure etc. or is there a enough "draft" in the chimney to pull right past teh fan? More of an HVAC question I suppose but I'm sure it's been done before.

WEBMASTER:  ..computer fans have very little power (for our applications, they are great for chips and such)... chances are the chimney if properly designed will naturally pull more air out then the fan can even attempt to do... computer fans are big let down to me.... as to carbon monoxide... never seen that problem with growing... not plants nor ballasts nor bulbs create enough or any CO to worry about... the reason you are ventilating is to maintain the temperature in the zone of 25 to 30C and also for keeping the smell down.... you are not ventilation because gasses are building up :-)


Comments

do you think the metal halide i told you bout at lowes for 30dollar has blue spectrum

WEBMASTER:  ..it has blue spectrum if it says metal halide on it... as long as its for veg period and not for bloom it should work just fine...


Comments

hey mark ...another silly ?...i have a super girl plant that turned male or hermaphrodite whatever u wana call it ,,,lol..we pulled it in time but not b4 she pollinated the other plant i have which is white widow strain called snow white...not many seeds tho...my ? to you is that the seeds that i get from these plants are they going to be a cross strain of mommy and daddy....and would it be very potent???...thanks

WEBMASTER:  ..the seeds are actually feminized.... a hermaphroditic female pollinating another female creates feminized strain of super girl x show white, very good for bloom but not so great if you want to keep a mother plant.... i cant say much about quality... on paper this strain looks good but you'd have to grow it and bloom it before you know how good she really is.... but , good parents make good offspring so she won't suck...


Comments

what size planter should I use for the two month bloom period If I'm using a 600 HPS. How big a planter is too big? I want lotsa root space, but the plant has only two months before i chop it. How much root space can it use in that time? thanks

WEBMASTER:  ..I never use pots bigger then 5 Gallon or 12 inches in diameter... I have 1 year old mother plants that are in those pots so that's enough space for a long period... if i have under 15 or 20 plants I generally use 5 Gallon pots but once I go over this number, say 25 plants I would go with the smaller size, the 4 gallon or 10 inch pot.... it would also be ok with me to  use the 3 Gallon containers (8 inch) since its arguable whether I gain yield because I use the bigger pot but I like bigger pots because I do not have to water them as often....

A friend and I went to check on a few plants we planted so we can water and check on them. You might have guessed already, THEY WERE GONE!!!. All our work was for nothing. Bringing soil in, carrying water, Hiking. WOW, somebody has all that weed of ours. You know what, Even though We were pissed off and cursed those bitches into oblivion, we figured out that it indeed was a nice time spent together hiking, and just hanging out. There were 11 plants, so we figured there was about 2-4 pounds of hopefully good weed. Shit man I got this feeling in my gut like somebody stole my first bike. I'm not pissed off anymore, cause that the name of the game, I'm just very sad. :(

WEBMASTER:  ..I hate outdoors for this very reason ..... any Dick or Harry can help themselves.... I feel your pain..

hey guys thanks for your help, to TONY, i wasn't sure if that link was for me or not but i checked it out and it has a great DIY section, thanks. and thank you mark for your response.

If a plant switched to bloom too early by accident (not enough light for one day) and then got put back on a 16 on 8 off light schedule, would it go back into veg? How long would it take?

WEBMASTER:  ..16 ON and 8 OFF is the incorrect light cycle, the plants need 18 hours of light (ON and 7 OFF) to be in the vegetative cycle.... after 1 day of 12 ON and 12 OFF chances are that nothing happened and the plant will continue veging ..... at worst the plant may hibernate for a week and then resume growing...

Herbert, here's a link to an article that describes how to make hash. Good Luck! http://cannabisculture.com/articles/2312.html

I always use pro mix for my plants. When I bought my new pro mix recently and started several plant, I did not notice until just today that the pro mix HP I bought contained an added ingredient called 'mycorse pro'. Seems it is a fungus that attaches to the root and thus stimulates growth. The plants are looking great. (still veging) I have no idea what this fungus will do to the end product however and am freaking out a bit. Do you have any insight into this? Please tell me it will be fine.

WEBMASTER:  ..it will be fine... I use it and its fine... personally I like BX over HP but its not a big deal since I use both ...


Comments

Just wondering if you knew a good site that shows how to make hash. How would you go about moving outdoors to in ?

FYI, Green CFL bulbs are available at Canadian Tire for 6$. They are the small curly ones, coated in a green coating and give off enough light to work in the grow room during the dark cycle.

The weepy diesels have bounced back...yeahhh

WEBMASTER:  ..miracle...

yeah , I'm with Bob (under me). My lady is yellowing too. I just flushed today. I'm growing in a 5 Gallon cont. and performed a 20L flush. I hope it might help a bit. when do I add the nutrients again? Is it the next time it needs watering? (depends on how close you are to harvest, if its one week and you cut, then I would not give her any nutrients, may be 10% of normal, BUT if she has more then 2 weeks to go then I would give her a normal dosage for a week or so) I'm about to start some bud boosters alongside my regular feeding schedule. Should I do this? She is very ripe and smelling really good, nice buds, but yellowing leaves, (are you sure she is not ready already??) what up? Ohh, forgot to mention. I feed her every time I water, that is about every 3 days. I use a and b formula for bloom now. Thank you in advance.

WEBMASTER:  ..if they are getting yellow they need nutrients, specifically a bit of nitrogen (switching to a veg solution of a and b for one watering cycle would be ok),  but if they are burning from the tips of leafs all the way to the sides and then turning burnt crispy yellow then its overfeeding .... outside its too late to add bud boosters because the temperatures are dropping and they can't process all the food... inside you should be in week 5 or 6 of bloom if you want to add bud boosters....


Comments

hello all. i have a few females big and budding, they have been outdoors since may. while i feel like it is not yet time to harvest, they are starting to get pretty yellow. not the buds, but many of the leaves are wilting and starting to fall. is this normal? or is it time for harvest? please advise.

WEBMASTER:  ..if they are getting yellow they need nutrients, specifically a bit of nitrogen,  but if they are burning from the tips of leafs all the way to the sides and then turning burnt crispy yellow then its overfeeding BUT it could also be her natural way of getting "ready".... this being the end of the cycle,... and the end of any good weather harvest should be the priority, in which case you can do nothing... take a small bud, dry it quickly under some light and smoke it... short high means its still early to harvest, good high should last an hour with munchies "bothering" you for 3 hours afterwards..... if you fall asleep its past its optimum harvest time....

Two questions: 1. Do plants finish earlier when heavily pollinated? (a little bit but not really, seeds are ready before bud is ready so it depends whether you grow it for seed or bud... the hair for example will turn colour quicker then in un-pollinated crop, but its not the only sign of readiness so its difficult to tell sometimes if its the seeds that are ready or is it the bud that's ready????) 2. Is a conversion bulb equal to a regular setup, i.e., if I used a 400 watt metal halide conversion bulb in a 400 watt HPS setup would I get the same results as if I had used a normal 400 watt metal halide setup? Thanks again. You guys are amazing! no, its always 10% less but its the 10% that usually does not matter .. like blue spectrum...so its still better to switch then not to switch


Comments

Hey Mark....I have to ask about this quick in case I am doing something stupid...I re-potted the 10 diesel clones into 5 gal buckets..they got a watering (water with 10% nutrients) but 3 are looking very wilted/weak.. like they want to lay down...what have I done????..poor poor little diesels??????

WEBMASTER:  ..transport is a big deal stress .... may be they got too much light too soon (like the blindness you experience coming out of a dark tunnel into the light) .... so keep them away from light for 24 hours, however afterwards they should be 3 feet away form the 1000W and closer as they grow... there is not much you can do but spray them often with plain water... and hope...


Comments

buddies got a couple pants up north and last weekend it went down to -2 degrees celcius, does the first frost kill them or what, what should he do , i heard a rumor that its the second frost that does?

WEBMASTER:  ..its no rumor... the plants behave odd when below 5C.. some die, some hibernate, some (rarely) survive... it is definitely not a good news for your buddy...


Comments

want to start leaching plants thinking of using small dosage of nutrient to pH the water, im using pure blend pro and the smallest dosage is 7ml per gallon for small seedlings or cutting, would this dosage work to pH the water and effectively flush the plants or should it be less or more ?

WEBMASTER:  ..when you use 20 to 25% of regular nutrient dosage the water leaches the roots, in promix you do not need to worry about the pH but if you are in the water system the pH should be controlled by you at around 6 or so.........in case of pure blend pro the regular dosage (as I remember, check your bottle) is actually 30 ml per Gallon thus 25% should be 7.5 ml per gallon.... if you mix the lower dosage and feed your plants for the last week of bloom then the smoke will be clean and nice.... hydro stores want you to buy leaching solutions for a lot of money, but those products are nothing but diluted food... extra water for extra money...


Comments

I have a few plants that just look messed up... where can i email u pictures so u can see and hopefully diagnose the problem...?? In addition is it true that when the soil dries out that the nutrient concentration in the soil goes up therefore causing overfeeding??? (who told you that so I can read it my self...off the bat it BS)  In the holes of the pots where the water drains from there is some salt build up, is that normal? (sure, I don't pay attention to it) how often do u leech your plants? (with proper nutrients, once in veg, twice in bloom, including leaching in the end, every second time if using the blue powders)

WEBMASTER:  ..join the Google group where you can leave the picture..... and post the question HERE but with a link to where the picture is... http://groups.google.com/group/toronto420-discussion-board ......

Hey guys! i am planning on making my own carbon filter, but i don't know where to get the raw activated carbon. would you guys happen to know where i could purchase such stuff in the GTA? preferably inexpensive? also i read a response you made about 600W having problems and such, should i be worried? thanks as always!

WEBMASTER:  ..I just don't know... try this but I am not sure they have the type you need.... when you get an issue with a 600W ballast its best to have 2 bulbs on hand at all times, when the ballast stops working replace the bulb and it will work.... odd but it works....

Hi Mark, How ya doin man. The hash plant and white widow cross are doing very well since using advanced nutrients Connoisseur. Also got rid of the spider mites after about 3 months. What I was wondering is who I should vote for. I want to vote for the people on our side of the tracks. Thanxs again and I will see you soon. Hope your feeling good in these days of our lives. Bye Now.

WEBMASTER:  ...please vote liberals.... and vote for the proportional representation on Oct 10 in Ontario, its the only way to get small parties like the greens or the NDP or the marijuana party into any meaningful power  .... the bottom line is that I would love to have NDP in power when it comes to cannabis legalization but they will spend my money like a drunken sailor and will never get power in ontario so its a vote lost..... liberals will steel my money and smile while they do it ... but I would still rather have thieves in power then fascists like the conservative party.... a real conservative would want to legalize pot just to get the government out of our lives, but the conservative party is nothing but a front for corporate Canada....

I am running a 1000w h.p.s....and am maintaining a pretty good temp 80 to 82F, the space is 250 sq ft has window ventilation and fans...if I add another 1000w mh how much should I expect the temp to increase?? please keep in mind colder temps approaching so colder air can be drafted in ...will that alone be sufficient to keep temps in my 80-82F zone ???/

WEBMASTER:  ....you are correct, but I would not use additional 1000W until the temperature in this room drops to 75F, when it does, the 2nd 1000W will bring it up to 80F or so.... any time now it should be cold enough outdoors.... hehehe you and the entire growing community is waiting for this drop in temperatures so real growing can begin....

Mark, I forgot to ask ..in regards to the "LEGAL MEDICAL," users clones....what strains are available ????

Is promix the only dirt like medium you can use or are there others

WEBMASTER:  ...not at all... promix BX, promix HP, sunshine mix no.4 are the brands are trust..... if you can not find the brands look for something that says professional soiless triple mix......... read lable and see if it supports pH around 5.5 which is good for both grass (lawn stuff) and grass (bud) ..... contractors use this stuff for lawns ... ask the garden guy what is the best soil for an outdoors patch of lawn, or what do the contractors use.....

i had 2 seedlings in grow pugs that were placed in 4inch rockwool cubes. the stems broke and you said plants are probably gonna die. they were in 4inch cubes for bout 4-5 days. can i take plugs and reuse the cubes or do i have to throw them away

WEBMASTER:  .not really, if there is roots in the cubes the roots will rot and infect the new plant, no roots no problem...


Comments

no im not blooming with the little llight, just veg.


Comments

Oh ok thanx for the info , but like if you add light wattage does it add up or does it not matter ( e.g 25+25+25+25 = 100 watt ) And It said the 25 watt fluorescent is really 125 but only uses 25 watts. So would it be possible to have 2-4 25 watt fluorescents and get some decent results. Also how far should I place a fluorescent light from the plant ?

WEBMASTER:  ...fluorescent lights have less lumens and even if you get 400W of combined power from fluorescent lights you still have far less lumens then if you had one single 400W HPS or MH light..... fluorescent lights yield enough bud for people who smoke once a week, barely...


Comments

I was just wondering a couple things, i am going to be purchasing a pack of blueberry skunk off of you guys and i was wondering, i have a space about 6 feet long, about 3 - 4 feet wide, and around 6 feet tall, would a 1000W light be suitable for this situation, i am using 5 gallon pots and promix. Thx for your time and expertise.

WEBMASTER:  ..the space could be a bit wider for your comfort but it is ok for a 1000W... you'll end up being a bit tight but that's life....

The best deal I have found on a 400w HPS kit is $199 plus $20 shipping. I bought one and it's pretty good so now I'm wondering about prices for higher wattage kits.. This place sells a 600w HPS for $309 (I hate the 600W since they have problems due to type NOT design.... 600W tends to shut off at higher temperatures and only changing the bulb helps....but the bulb is not broken, several electricians tried to explain this to me but I just don't understand) and a 1000w for $259. (I have no idea why the 1000w is cheaper....less popular, less numbers sold thus less produced thus more expensive) Metal Halides are $229 for a 400w and $279 for a 1000w.(400W is normal price but the 1000W is a good price) All of the above are complete kits ready to plug in to a standard wall socket. Yes, they come with the bulbs. What I am wondering is, does anyone know where you can get a better deal than these, or are these prices pretty good? I have not been able to find better prices but that doesn't mean there aren't any. Any info on this subject would probably help a lot of people. Thanks. (My sativas aren't impressed with the 400w so I need to get something better soon.)

WEBMASTER:  ..the prices are competitive for the type of lights you want, you are not being ripped off nor are you saving serious money..... you can always try to pay cash to save on taxes.... Craig's list or eBay often has used stuff at half the price you quoted....


Comments

Joe (and anyone else who's interested) - Canadian tire sells a "Shop Light" that holds 2 - 4 foot fluorescent tubes for only $18. (You have to buy the bulbs separately of course.) These are great because they come ready-to-go, just plug 'em in and your all lit up. They are metal, sturdy and come with short chains and hooks for easy hanging. Best deal I've ever found. I know your room is smaller than 4 feet but I'm pretty sure they sell the same thing in a 2 foot bulb size, i.e., 2 bulbs x 2 feet. Hope this helps.

hey mark just wondering if feminised strains are just as potent as their counterparts???? snow white and supergirls are the feminized strains i have and are ready to harvest....just wondering ...thanks

WEBMASTER:  ..potency is depended on the strain not on whether its feminized or not... feminization changes sex but does nothing to potency...

the metal halide and high pressure sodium bulbs were 150-400watts and cost bout 30 dollars

WEBMASTER:  ..yes, that's the price....

hey mark, i took my 120 watt agro plant lights back and got 2 plant aquarium lights (you seen em before) 2ft fixture with a plastic light cover over the bulb. you can get them at almost any hardware store. they are 2ft fluorescent lights that say they output 75watts and only use 17watts of energy. (sounds right) are theses lights ok to use (for veg yes, for bloom no)....if so am i coo with 2 lights in a 3 x 2 room or do i need more lights. i went to lowes and seen that they sale metal halide and high pressure sodium bulbs(150-400) they are made by sylvannia (forgot how to spell it but you know the bulb company) (they are fine) are these good bulbs and one of my grow plugs and rockwool cubes has a lil orangish red on them, not alot though. is that a problem or will that just happen and i shouldn't worry

WEBMASTER:  ..I do not know what orange colour would come from in your case....


Comments

I'm very curious as to why you don't like the "blue powder" nutrients. Is it because they are so highly concentrated (yes) or is it a 'dissolving' issue (also) or what is your main reason(s)? I have used Miracle Grow Ultra Bloom without any trouble but will definitely not use it again if I shouldn't be. So what's up with the blue powder problem? Thanks a million guys.

WEBMASTER:  ..I used it all and its all the same but especially for beginners its difficult to be careful and they overfeed the plants... blue powders are VERY concentrated thus many people make dumb mistakes ..... but if you used it and it worked there is no problems..... another reason that I do not use it is that the blue powders are made from petrochemicals (i.e. oil).... not really organic and I strive for organically grown cannabis....

Hi Mark n Dan. I don't know how you can do this, you know, answering all the time n shit. I think there must be a forum program out there that's not IP anal (NONE), and one can post as long as they put in that random generated copy code (you know what I mean, those crooked numbers). This way we could all share info and you wont have to answer all those hundreds of new repetitive questions like "what light should I use", not to mention more advanced people would help out, you could get moderators. A place where we could put pics n videos of what we mean when we have problems etc. Hey, I'm not really internet savy, but if anyone is perhaps people can try n find out if such software exists so we can learn n bee free. :)

WEBMASTER:  ..I did set up a Google forum that gives everyone the ability to post pictures and has few restrictions but people do not seem to pick up on it.... I can not moderate the forums on Google and I was hoping that some people would, there is a lot of people who don't even know where to start ..... I actually work so I can not moderate the Google... this forum was originally with the intent that ONCE you ready the Grow Guide you post a question here IF you can not understand.... but it just never works out this was....

is it possible to cover up the strong odor that the plants produce?

Hey Mark, just wondering about the skunk 69 , I sprouted 2 of the 10 , and there doing great! I wanted to know if I'm to grow one/two plants in a closet, what's is the bare minimum wattage for me to use without them being unhealthy?

WEBMASTER:  ..the plant is a weed so it will be "healthy" under any light including incandescent bulbs... as long as you remember that the smaller the light the less nutrients it can absorb... if you get $25 fluorescent light bulb, it would hardly take any nutrients and stretch like crazy, and yield almost nothing but it would live and be healthy... "real" growing however starts at 250 Watts, ... bare in mind that even 250W is a quarter if what I need to have growing at any time to give me 1.5 ounces per week to smoke myself.... I am a heavy and very much legal smoker ....

Hey Mark ....as add on to Q below....what about the Odorsok w/fan 150a for $300.00... Your Opinion?????? TXS

WEBMASTER:  ..this is the untested system that just came to the North American market from Europe... problem is that I only trust opinions of other growers and not marketing guys.... so the specs on the filter are very good, but I know no one who used it so I can not recommend it.... I encourage experimenting ...... I do want a cheaper alternative to the heavy and expensive filters we have now .... but since I grow pot I can not afford to have a bad filter ....


Comments

should i just go with promix if im having problems or should i just stick it out with the drip metering/watering system and learn

WEBMASTER:  ..I "push" promix because its easier and people succeed, even if they screw up, this is the bottom line..... when I ran a hydroponics store and people used any other method all I heard was crying.... constantly... problem was always incorrect understanding of pH of the water .... if you stick with the water system, check and double check the pH often and always...

if the bulbs are no good what fluorescent light can i use. my closet is small 3 x2,when seedling get bigger i will move to a bigger room, can i use a simple fluorescent plant aquarium light (sounds right, one example, more expensive types), you know the kind where you just hang it up and cut it on. you know they come like 8watts to about 30watts,is this a good light to use, (for seedlings they seem ok, generally when its says Aquarium lights or such it means its the better type of plant spectrum good for plants) how many would i need. and one of my seedlings stem has white spots on it....what does that mean. i bought flora series nutrients and some up and down bout a year and a half ago, is it still good to use

WEBMASTER:  ..flora nutrients should be able to last a year, but year an a half I just do not know... I want to say its no good but I used old nutrients before and had no problems........ your fluorescent lights are good for clones, small mothers and seedlings but they are not that great at blooming plants I hope you know that....

Thanks Mark I have spoken to Keith at the store..he suggested the Elicet 150b fan but its 279.00..what about the Airdex Squirl fan 400cfm ? its only 170.00/this can/ filter set up looks like 300.00 + fan (170 to 300)=5-7 hundred?? WOW!!! its a lot of cake for a white boy on disability.............can u suggest used? ????

WEBMASTER:  ..unfortunately the stuff is expensive ... the squirrel fan is cheaper but louder so if sound is less important then get the squirrel fan.... try shopping around on Craig's list or eBay but realistically the good fans are expensive... do not get any used can filters, not worth it....

Hey Mark...in regards to my coming again Friday ...I also have a situation were I must get some form of carbon filter can you please advise on the best type.. if you remember my room is sort of hexagon shaped but the sq ft is still 180...I have someone in the house that even the chlorophyll smell is bothering so I have to get it now...I do have window/vent access if it need to be vented outside...thanks for your advice

WEBMASTER:  ..this is the filter you need CAN 50 or CAN 66..... call this store and find out if they have it in stock... ask for equivalent filter if they are out of stock of this brand, I know they also have Dutch Master filters which work just as well.... note: they have a new filter (I forget name) that's half the price and 1/3 the length ..too good to be true, from Amsterdam, blah, blah.. do not fall for this, this is a new product and you don't want to be a guinea pig, not that its a bad product , far from it, but I do not want try new stuff as long as my old stuff works ... as long as the filter works in the 200 to 400 CFM range it right size for you....

I am growing 4 indica in sunshine mix and was wondering if it was ok to add nutes at 50% strength every time I water every four days? Also, the tips of my leaves are brown (not yellow) and the edges are curling upwards, what would cause this?

WEBMASTER:  ..its better to give 20% once and 50% the next time and more if necessary, you actually take out the bad salts building up then always giving them 50% ... watering every 4 days sounds right with sunshine mix.... if you have 400W you may be overfeeding but if you have 1000W this may be a different issue... best bet would be to remove nutrients by leaching immediately... it takes a week for a plant to recover .... I hope you are not using "blue powder"-like nutrients...

420 Friendly Areas/Parks in TO Hi there, I'm flying in from Vancouver on Friday, wondering if somebody can suggest any 420 friendly areas where a BC Boy can feel at home. Cheers, Jake

WEBMASTER:  ..Roach-o-Rama on Baldwin St. in Kensington Market or Kindred Café off Yonge... either way you can't buy, but you can smoke...


Comments

mark, the 120w plant agro grow light is made by phillips

WEBMASTER:  ..sorry this bulb is meant to be a supplementary rather then a primary light....


Comments

i have 3 seedlings. two of them have green green top leaves. there bout 4-5 days old and i have one seedling which is bout 3-4 days older and bout two inches taller than the other 2.its leaves are green but jus a little lighter, its not real light o lihtish yellow, its just a little lighter than the others. does that mean anything

WEBMASTER:  ..it looks like slight underfeeding... feed her 20% more nutrients and if the colour does not become darker green feel free to add more nutrients on the next watering cycle.... to me this is a good sign, means the roots are growing and the plant wants more food....


Comments

Hi 420,i have bb skunk and jf x nl x sk. Do either of these strains need any special attention or grew any diff. than any other strain

WEBMASTER:  ..heavy indica strains are generally easy and tolerate stress well.... either one can be ready at the end of week 7 in bloom so watch out at harvest ... you may have to start leaching sooner then expected...


Comments

When mothers and branches are big enough to be cloned, how often can you cut clones (once a week under 1000W, less often under smaller lights, every 2 weeks under 400W), how long does it take for branches to grow back (from one week under 1000W to 2 weeks under 400W)


Comments

When should you water plants with nutrients, soon as they sprout n have lil top leaves or when there and inch or 2

WEBMASTER:  ..I mix a very low dosage and start introducing the nutrients as soon as I see some leafs.... 20-25% of normal level of nutrients is best...

Mark i am a heavy smoker and only like good stuff. I wanna start growing my own for personal only. One plant. Ill be up north in two weeks so thats when i will purchase. I would like to know what the hardest hitting seed you carry. I know you will give me a couple or say all of them are good but honestly since your a pro at what you what would you say the strongest potency strain you've got or ever smoked. I heard ak 47 (don't like her or any of the brands products) but that's from my friend an ordinary street smoker not a pro or a person who has come in contact with many strains and flavors

WEBMASTER:  ..its true I am the worst person to ask, but I think you are looking for anything that says 80% Indica or more.. assuming you are trying to "quite" you mind and body...if you are trying to motivate your self its not about Indica but about a mix of Indica and Sativa... I would try to get as much 50/50 split in a strain as possible, brand or name makes little difference its the ratio of Sativa and Indica that matters... I am always pretty adamant about the fact that you should grow 2 strains ... your brain "unclogs" when you alternate your intake with different strains of cannabis ..quality cannabis is about 2 things to me... leaching it properly and cutting it at the right time... but this is for advanced growers and you may need 2 years before you "get it"... I can feel (smell and looks and stickiness is just perfect and I have this gut feeling that if I don't cut it NOW the perfection will be gone) when cannabis is perfectly ready.....but you have 2 days of optimum harvest time.... pick it on THE day it absolutely NEEDS to be picked and you get amazing results, medical quality bud... be wrong by 2 days and you get good weed or street weed, but as you know there is street weed, there is good weed and then there is perfect weed......

I feed seedlings 3x for 30 minutes a day is that fine. I accidentally bent one of my seedlings and bent it to the point where it was a tear and seedling began to die. I tore the dead part of the stem off. There is a little stem still in the cube. Can i still water the stem and the roots place under light and bring the plant back and re-grow it or is it dead

WEBMASTER:  ..are you watering because the roots need water and are about to die? or because someone told you to do it... off the bat I would say you are feeding too much too often... in a hydrotone based system I would feed continuously with a dripper but on a rockwool system I would feed once a day only... about the plant: its probably a goner... it may recover but not if you are aggressively feeding the rest of plants...


Comments

Mark, looks like I have to make another hospital trip end of the week so I will probably want to come by I will call you ...... Thanks

WEBMASTER:  ..pls. call me ...

hey mark i asked you a question about how far to keep my light away from the tops of the plants and you answered me with helpful advice (you told me 2 or 3inches)i was doing 8 to 12 inches away so thank you. i told you i had a 120 watt agro plant bulb. it doesn't say fluorescent on the box from what i can see .the bulb screws in upward and has like a royal blue coating on the bottom. now im gonna ask a question i asked before since now you might have a better understanding of the bulb i got. my seedlings are 4-6 days old. my questions are how many 120 w agro plant lights should i use i have one bout to have 2...should i get more, there cheap like 7$ a bulb and 7$ a hood but the bulbs do say agro plant light.) and should i still keep em 2-3 inches away from tops and for how long...when do i raise the light(s) up. when do seedlings start to develop branches. my closet averages around 85 86 degrees %f and 38-40 humidity. is that a problem or am i fine. i know temp. is beginning to drop a little since the season is changing so that a help. do you veg for 1month or two. i heard 2 if you want big enough fem to produce around there max. i know is a long note, sorry but your so helpful, better then any book

WEBMASTER:  ..I was confused about why you are having problems.... here is what I found on other forums .... don't expect any major results, and be prepared for some plant stretching, they will. The light spectrum can not be produced by dying the lense and expecting a arc flash ( filament ) to produce any ( real ) usable light...... they are cheap lights that will give you cheap results.... sorry.. that's why they are 7 dollars a piece...


Comments

The 6 hour thing was a BARE MINIMUM. I don't want to see you moving the lights too close too fast. READ MARK'S GROW GUIDE, it will explain about moving the lights with seedlings. The seedlings can be supported with a popsicle stick or something better if necessary. Above all, quit worrying!! If someone asked me for the best piece of advice when growing cannabis I would say: Leave them alone. Nature knows just a bit more than we do. :) Now I've stuck my nose in twice, I am sure to get it cut off. Sorry, I promise I'll try to never do it again.

WEBMASTER:  ..pretty good advise :-)


Comments

This is for the guy with the "stretched" seedlings. You sound like you're in a panic so I'm adding this. Hopefully I won't get banned from the forum for sticking my nose in too far. :) RELAX!! Your light, if a fluorescent is too far away at 12 inches and the seedlings are trying to get there as quick as possible. Move it to 6 inches and if they don't "bend" after 6 hours, move it even closer and do this until it is 2 inches away from them. (ONLY IF IT IS A FLUORESCENT!) Sometimes young seedlings can't handle being too close to the light but yours could be ready, that's why I said do it gradually until you get to 2 inches. The stretching won't hurt you in the end as long as everything else goes fine. SORRY for putting this up here but there seemed to be a lot of PANIC going on. Mark or Dan will fix anything I said is wrong. I do not guarantee anything. :)

WEBMASTER:  ..you are very correct ...and I do welcome a response to someone who is in panic.... I promised my wife not to work on the weekends so if you post a question on Friday I won't respond till Monday at best...

Thank you, I received the seeds today & appreciate it greatly. I was wondering how long seeds can last packaged? (years if they are in darkness at the bottom of the fridge not set to coldest setting) And If a plant can grow next to a window in the winter? (not really) Would the glass be too cold even if the house is warm? Would it get proper amounts of light? ( and I'm only talking about a single plant not more than 2 for sure.) Thank you.

WEBMASTER:  ..its not like the plant will die or anything, so long as it receives some light for 18 hours a day the plant will be in a permanent veg cycle but it will not really thrive... it may stretch too much or grow very slowly or just bend in weird places... if in the summer it would gain an inch a day, in winter it will gain an inch a month... or just stretch ....

I was just wondering if there is any walk in seed banks near Kingston ontario canada?

Hi. I have a six foot plant outside in my back yard, my question is in regards to security. Some of my neighbors have seen this plant (i have a basic 4 foot see-through fence), and are curiously smiling when looking at it from the distance, I have seen them grin. I'm just afraid it'll get stolen. Its got around half a pound of bud on it and its gorgeous. I want to know if I can put it inside. I have good ventilation and 1000W hps light. I basically want to finish the last month at home with proper darkness and love, you know right now there is less light outside (big, big problem) and lots of rain so I'm also worried about mold (I would too). Should I do this? (I will never ever tell you to outright DO IT, its a roll of the dice issue, on one hand you have more yield but mold and cold can kill it, on the other bud is saved but less yield) and by doing this will I increase some yield? (decrease yield, but still, less yield is better then NO yield if the frost or mold take) thank you in advance. worried.

WEBMASTER:  ..generally I would say NO way should you bring her indoors, however given how quickly the weather turned to cold and cloudy, it may actually be better for her to get more stable (if weaker) light.... 1000W is (may be) 50% of what she gets on a clear day... but we get few clear days now.... stealing is definitely a STRONG possibility..... but my gut reaction is that the neighbors want to be friends :-)


Comments

I have an outdoor plant going right now its in its 5th week of flowering, just wondering when i should start to flush, i know some go for 7-8-even til 10 weeks before there done

WEBMASTER:  ..if you have cold weather it would be wise to start flushing now just in case the season turns to frost.... 8 weeks is a term you can use for indoor plants but for outdoors it may mean different things.... generally by end of September I would be expecting harvest from a plant labled as 8 weeks and mid October for plants labled 10 weeks.... flushing should happen 2 weeks before harvest....


Comments

Ok this has nothing to do with me stopping by, Its about the 3 fast pine that are still alive ( for now ), They are about a foot tall pretty bushy and look healthy, But as the summer comes to an end our stupid weather here will get really cold soon ( and windy ), How can I force them into bloom immediately so I can get some bud before winter comes ?

WEBMASTER:  .. the only thing you can do is to religiously (every night and every day) pull a dark cover over the plants, every 12 hours to make sure they get perfect pitch darkness for 12 hours a day.... the more you do this the faster they will show buds... amazing how quickly the weather turned from very hot to very cold...


Comments

i meant to say so my seedlings don't stretch. how tall should my seedlings be 5days after be sproted, what should they look like, i have my light 12 inches above the tops is that to close or to far away

WEBMASTER:  .. unless this light generates a lot of heat the plants should be 2 to 3 inches away from the bulb... 12 inches is way to far.... in your case over 24 hours bring them closer to 3 inches ... if you see any wilting or strange behaviour pull them back... but they should be fine and stop stretching....


Comments

Add on to my last Q below...The Sensi a/b containers are weird they list PPM from 600 to about 1400 for/per 1 litre anything above 600 called aggressive feeding so I stuck with 600 ppm....1.8 ml/litre does this sound right Mark? 1.8 of A then 1.8 of B Thanks Dude

WEBMASTER:  ...is this the same lable as on this site? ... in your case its still ok because they should be big enough to survive... but I really got confused with this lable... I would have overfed my plants with this product  ....  your "normal" full feeding is 2 ml per liter .....


Comments

one of my seedling is stretching, how can i fix dat. how many 120watt agro plant lights do i need so my seedlings do stretch

WEBMASTER:  ...not much you can do... some stretch naturally, that's the nature of seedlings... some are faster then others...


Comments

Hey Mark...I bought a new ( to me) brand of nutrients yesterday .."Sensi Grow" a+b ( its a little more $ but it is supposed to be becoming really popular fast)....the container is not very descriptive about instructions so I am a little apprehensive about the amounts to use in ...1 liter (as example)...can you please advise?? this is the first feeding for this batch re our conversation yesterday/////Thanks dude Cameron

WEBMASTER:  ....the lable on the bottle should give you an idea what the full feeding is, as in 100%,..I see why you are confused...I found the lable on this site , I see that your normal dosage is 2 ml per liter, there is a chart which means well but it is VERY confusing....if they are now under 1000W they can take 50% of nutrients the first time you water them (1 ml/L) and 100% next (2 ml/L)... 75% the 3rd time... then its probably best to go between 50% and 100%... from the chart I can tell that its OK to feed your plants 3 ml/L ... do that only when you see very light green almost yellow colour on top leafs of the plant.....

HI; I was just reading how to detect male plants and I am getting a wee bit nervous. I still have at least 2-3 more weeks of veg state but from what I have read males grow faster than females and are taller. I purchased 5 skunk69 (feminized seeds) and now have 3 tall plants and 2 smaller (less than half the size of the taller ones)...is this any indication of the sexes of these plants or am I getting too exited too soon? Obviously I am hoping for a majority of females hence the reason for purchasing feminized seeds.... Should I just chill or should I be concerned?

WEBMASTER:  ..there is no way to know in veg... these are feminized so there is a chance they could go hermaphroditic but never a pure male... at this point its just your anxiety... 


Comments

Hi Mark; I'm getting a little impatient and was wondering if there is any benefit to leaving my light on constantly (24/7) for the veg stage of my plants or is it better to stay at 18 on 6 off. Regards

WEBMASTER:  ..I must admit that I have been using 24 hours of light for the past 5 years... I do it because its cheaper NOT to have timer in veg and since I'm legal I don't care about power (but pay higher bills) .... I do not know whether its better or faster, because I do it out of laziness.... and to test it you need identical strains under two separate grow lights with two light cycles...


Comments

Hi Mark, thanks for help over the last couple of years. Quick panic question - I have 2 batches flowering, at 4 weeks and 6 weeks (several varieties, I expect the first ones to be about ready in two weeks) under a 400 and a 600 HPS. The circumstances are a little less than ideal, doing construction on room and heat can get too much (I think I average about 84 with the door open, 2 fans, 50% humidity maintained w/ a dehumidifier 24/7). First batch showing varying nutrient deficiencies, brought on by the heat I guess. Still looks like I'll get a reasonable to good yield. Been perfect with the 12/12 since it started, but accidentally left the ceiling lights on last night, about 45 CFL watts but fully lit nonetheless. Therefore, they're in the middle of a 36 hour day right now. Bummer, the last time I will grow under these less than ideal circumstances (I have a hydrohut on the way). So what should I do prevent male flowers? Would 36 hours or so of darkness be of any help? Or should I just hover over the buds like a hawk to manually keep pollination to a minimum? The varieties are Almighty's Lionheart (8 weeks I've read), some self seeded Next Generation Grapefruit Haze (these female seeds might be a little hermie prone I figure, about 10 weeks) and one called Haze-y from an unknown breeder. Next time out I'll use yours, I promise! Thanks again for your ongoing help.

WEBMASTER:  ..there is nothing you can do, but lower the nutrient level for 1 week after this .. it would be a disaster to me.... not to my Vietnamese friends who claim after the 5th week it matters little where you have some light or not in bloom..... I agree that in the 4th or 5th week its too late to turn them to males so if you have seeds its not because of this problem... but I do not want to be the one to test this "theory".... so may be you can tell me..... according to me, the plants would not really turn male, but the plants would stop developing for 1 week and then start again (hibernate)... I would add 1 week to my blooming cycle... ex. Almighty's Lionheart became 9 weeks bloom instead of 8....... i am a bit worried about the temperature jumps... but I guess 84F is still in my zone of comfort... on the good side you will find out which strain took the abuse better.. that's how I end up picking my best strains, stress them and see which one survives :-)


Comments

do you keep fan on for 24 hrs in veg (I kkeep my lights in veg for 24 hrs. thus my fans work 24 hrs...) or 18hrs,whats better for plants in veg. 24 hrs of light or stick to 18 hrs of light

WEBMASTER:  ..I prefer 24 hours of lights in veg... to me they grow faster but it could be argued....


Comments

whats going on, i have a 120watt (fluorescent) plant light (im gonna get another one), i got the plant bulb from lowes, how far should i keep light(s) from the top s my seedlings. (1 foot is the furthest and 2 inches is the closest, depending on the type of fluorescent... 3 inches would be ok for 90% of lights out there... note NEW T5 fluorescent lights are very strong and 4 to 5 inches would be ok for those) one of my seedling stretched a little bit when it wasn't getting alot of light. its 4days old and 3inches tall. what can i do about that (nothing, unless its ready to be cut in half... when it has ANY side branches its ready to be cut) or am i just wondering to much. when do plants spread out a little and form branches. If you have a small closet 3x3 can you use an ordinary walmart twin fan where you can set each fan to out put or intake or do you have to get an expensive extraction (proper term would be INLINE fan.. I like fans to the point of knowing which brand is manufactured where and how good it is) or squirrel (works but its loud)

WEBMASTER:  ..you can use whatever fan you wish so long as the temperatures stay where they should, below 30C (85F), my first fan was a $19.99 home depot bathroom fan ... I recommend getting a "profession" inline fan only when you have lights bigger then 400W... because until you have a 1000W light opening the door ventilates this space just as well.... 


Comments

...yeah. Good question (you know... below)

WEBMASTER:  .... when I find out I will let you know.... but to the "Concerned Canadian"... call me and explain or post here for all to see please.....


Comments

well now....should others with a permit to posses and to grow be worried?????Your scaring me dude!

WEBMASTER:  ....Health Canada is bluffing, I know because I called their bluff.... they are however directed to prevent further spreading of the permits.... the only way they can do this is to scare doctors with imaginary problems....


Comments

Mark, what difference's (if any of benefit) are there between metal halide clear and phosphorous coated bulbs???

WEBMASTER:  ....I never used the coated bulb because it has less lumens, thus less value to me.... the more lumens the better...


Comments

Mark: I do not want to post here what I want to tell you. We have spoken on the phone a few times and I want to let you know about an awful experience I had, please let me know how I can get in touch with you!! It is related to growing and my license to grow! Thanks!

WEBMASTER:  ....I pick up the 416-824-5156 phone from 1 till 3 pm weekdays, call me, try more than once if you have to .... is this about Health Canada scaring doctors or the one where Health Canada threatens lawsuits? .... both are actually breaches of court orders .....


Comments

any heads up on what i should be looking for regarding when seeds would be ready/ripe on plants? they were pollinated bout 5weeks ago. still lookin pretty green. no complaints here thanks for the seeds and info.

WEBMASTER:  .... the bloom cycle is generally  8 weeks, and when the cycle is over, the seeds are not yet ready... you still have to let them cure.... some seeds will have stripes and those that do not will get stripes... there is nothing special about curing seeds... let them be exposed to regular room temperature (in darkness) for a week and they become darker and get more stripes..... I would take a bud off and look at the seeds that are there.... at least you should find some....

I just wanted to make sure there is no confusion because a trip to your store takes a good chunk out of the day to get there and back. So I will have someone name Max come to the store with the receipt, and he will pick up the 10 pack of skunk 69. I really do appreciate your understanding of this and thank you for the skunk. It would be really great if you could be there this weekend when he comes so there is no mis-understanding because I would like to further continue business with you threw out the years ( only legite place I've found so far. ) If you could confirm this it would be great. Once again thank you.

WEBMASTER:  ....your friend will meet my friend named Reza.... he runs the cafe.... bring the receipt and I will tell Reza of this to make sure.... if there is any issues .... just ask him to call me... he has my cell .....

THANKS Greg !!!! ALL to sad but true.....I would hope that the forum you were on was American.. the comments you referred to seem very much in line with the Americans I know...mostly too stupid to qualify as actual life forms ( MOST Americans, but NOT all.)( They [U.S.A.] go to Mars looking for life.. when they get there.. "the life" won't recognize them) Yet, I certainly would not be surprised if the comments were from Canadians too. The same people that drink that legal, "STUPID JUICE" that alcoholic brain damaging intoxicant.....society is so F.. #@*&ed up !!!! Citizens REMEMBER !!!...that our provincial election is around the corner.. for every person that DOES NOT VOTE...SHUT YOUR PIE HOLE>>>>if you don't vote ..YOU CANNOT BITCH...and please remember that if you enjoy the privilege of medical Mary Jane and wish the rest of legalization to occur...then voting anything other than Liberal or NDP will get you another freeze on legalization.. maybe even a reversal of the medical access laws.

WEBMASTER:  .....  Please Oh Canada vote NOT for the conservative evil do-ers.... so we may enjoy few more years of some form of poor version of a cheap nightmare of paradise with the liberal or NDP? ..... anger transferred into humor .... or sarcasm.... if not for cannabis the hypocrisy of this life would make my head burst...

Just thought I would put this up here so everyone can see how much work there is to do regarding educating the public so that it will be easier to get marijuana legalized one day and/or help lift the hassles associated with medical pot use. I was visiting one of those question and answer forums yesterday and someone asked if medical marijuana was legitimate or just a con to get weed. Here are some of the things some people said in their answers: ALCOHOL can kill you unexpectedly; smoking one joint of CRACK is enough to become addicted for life; pot makes you see (NO) , hear (NO) and feel (YES, oh YES) things that aren't really there (Thank God) making the person who smokes it highly unpredictable (is that bad or good?); marijuana alters your brain (YES) so that, after smoking it a few times you can never be the person you were before again (No...and I have changed when I discovered jerking off, drinking, ... titties... milk is associated with a scary part of my life)... There were more but I can't remember them all. :-) (pot makes you lazy, this ones on the house) I couldn't believe my eyes when I read this ludicrous junk, but it was also educational. There are still a lot of people that have poor views of marijuana for reasons that they honestly believe are true. I feel that, as long as the old myths and these other stupid ideas exist it will be very difficult to pass any legalization bill and/or get people to understand that marijuana really is an excellent medicine. So folks, educate whenever you can because there are many idiots out there passing along bad information to people that don't know any better. Hope you guys don't mind this post - I really felt the need to put it up here. Thanks.

I have a Sativa plant (supposedly Haze but I have my doubts) at 5 weeks of bloom ... however, it seems like it hasn't changed at all in the last 2 weeks, meaning that, the buds don't seem to be getting any bigger. The buds look like a brown colour to me (under an HPS) and many of the leaves have a very thin white tip - looks almost like a hair at the very end of the leaf. If it is Haze (or something similar) I know they take a long time to finish - 10 to 12 weeks - do you think that's it or am I worrying for nothing. (Not uncommon :-) ) The buds are 'lightly' sticky and my guess is there is about 1 - 2 ounces of it. (It is a spindly plant but has always been healthy) I guess what I'm wondering is if it is possible for a plant to finish early? The 'bud hairs' look like an off-white colour, but not very close to white if you know what I mean. I'm just going to leave it and see what happens but your input is always helpful so I'd love to hear it. Thank you.

WEBMASTER:  ..the buds do not get much bigger in size in the 5th week of bloom... 5th week is for bud booster feeding... i.e. filling in the insides of the bud... when I start leaching nutrients in the mid 6th week of bloom (if I know I have 8 weeks to finish, with unknown species, you never know), the buds starts getting bigger again.... but leaving them longer then 8 weeks may mean more yield, but it also means lower quality.... on the other hand I have White Shark and Sour Diesel in bloom week 6 day 6 (....in a legal location in an industrial building :-) ..... that are done and these are 8 week bloom plants, they are plants I developed and bloomed previously for 8 weeks... it just happened that with lower temperatures judging by the trichomes and the hair.. they are done a week early... I am surprised myself.... its a combination of methods that tells me they are finished... not necessarily the calendar itself...

In veg. and you have your light set to 18 hrs on, (I have it set to 24) do u keep your rotating fan on the whole time or is it set on a timer (its on timer, same as the light cycle), do you keep fan on or off (I assume you mean the outtake fan... always ON) when plants are in darkness (sleeping). when feeding plants (3x while light(s) on, bout every 6hrs) how long should they be fed...30 min 45 min an hr or longer every time pump comes on. when are plants strong enough to be fed nutrients (until you feel they have enough, 30 minutes seems excessive by 20 minutes to me) ...soon as they sprout, a week after they sprout or when they get a certain size. thanks for listening (when they have well defined leafs, usually 2 inches high, you start slow with low dosage and up it as you see them gain height....)

WEBMASTER:  ..please always remind me what medium you are using.... I am having problems answering....

can u use a 500 watt halogen light in veg. (no, they produce heat, not grow spectrum) do they make blue spectrum halogen bulbs caz i have a 500watt halogen lite sittin in my garage.. never used (its built like a hp lite....dome shaped with a glass cover at the bottom).(most likely its the same thing BUT I am not aware of ANY 500W HPS lights bulbs, there is 400W and there is 600W... so I guess the answer is no) i also seen a also seen a high pressure sodium halogen light system at home depot. (again, no because the heat produced by this light is too much )..can that be used for veg. or flowering since it says its a high pressure sodium light system. If you use a fluorescent light does it have to be a certain type (best to look for lable GRO or Aquarium Lights) or can u use almost any fluorescent lights) that's has enough lumens....(there is so many brands there is no quick answer.. in general NO)  To get the max out of my plants how long should i veg them? (probably 3 weeks , once they reach 1 foot long you must bloom) how many months and how tall should they be. if i use a low amount of fluorescent like 80-100watts or a lil less will that hault there growth. can they grow the same size as if u used a 400 600 or 1000 watt bulb in veg. if so i know u probably have to veg. them a lil longer with fl lite

WEBMASTER:  ..fluorescent lights are only good for 1 foot away from the bulb..... it means your plants can only be 1 foot tall before you have to either transfer them into another light or clip them, if you do not the plant will shed the bottom leafs, below that 1 foot mark, leaving only the top half healthy..... this is the limit of pretty much every fluorescent bulb... there are better bulbs, like T5 but they are not cheap which defeats the purpose of fluorescent lights...... they are bright for humans but they have no distance when it comes to lumens (stuff that grows plants in bulbs)... it takes longer for a plant to grow under fluorescents then under HID lights .... but not as much as people think.... in your place I would have 80W fluorescent light, tightly packed with plants (30 or 40) in beer cups in promix.... from clones wait may be 2 (2.5) weeks before they all reach 1 foot, from seeds add 2, 3 weeks at least.... throw out small ones and the weaker ones leaving only 20 good plants.... transfer under a 1000W, transplanted into 4 gallon containers, pinched and vegged for another week, may be less..... bloomed...  so I guess it would take a month in fluorescent lights to get them ready for the 1000W... and you could get away with 3 days of veg under a 1000W.... but you still need the 1000W to get the plants "used" to the bigger spectrum... in other words, when you transfer plants from fluorescent lights to 1000W HID you must pull the light back to 4 feet from the plants for 24 hours, if you don't they will wilt and die from stress.... feed only very little nutrients (25% to 50%) for the first watering cycle... after 24 hours you can pull the light back down to 2 feet from the tops....

Hey i purchased some seeds from you guys the other day... they haven't sprouted yet and I've followed the correct method... i no it says it takes a few days... but is that normal? should i be worried? tnx

WEBMASTER:  ..it may take 7 days ..... wet napkin in a dark place method?


Comments

Thank you for your reply , But would it be possible If I (or someone in my place ) went to the store to pick it up because I don't trust the government ( includes postal service .) thank you

WEBMASTER:  ..sure ... i would prefer you or someone else brings the receipt card but if not, have the stuff call me if there is any confusion....

now that the plants are budding is it a good idea to take off all the leaves (NOT unless they are brown and dead), and what do you do if your dried bud smells like hay.

WEBMASTER:  ...when it smells like hay it was not dried properly and/or not leached well, but  it can also mean it was cut too early or stressed through the cycle ... but ... provided the plants were flushed for at least a week before cutting, properly dried means that it was hung upside down in a dark place...... for 3 days minimum.... 7 days is better.... you can regain some flavour/smell if you dry it completely and then store it in an air tight container at the bottom of the fridge.... it helps if its compact and not too loose ....

my bad 18gal. reservoir


Comments

Lets say you have a 18gal.you have water in your reservoir and you mixed in the right amount of nutrients, after plants start getting feed and the water level begins to drop, my question is when do you refill with water? when it gets to what level? do you retreat water with more nutrients? how does that work? when should you change all the water and nutrients? is that considered flushing? (flushing is when you mix only 25% of regular recommended nutrient, this removes build up on the roots. thus "flushing" the root system, best not to do that for more then 3 or 4 days in a water culture system... in promix it would take over a week)

WEBMASTER:  ... I would mix 18 gallons of water with nutrients, check the pH and soak the plants once a day via pump (hydro system with rockwool or coco fiber)... I would not be too concerned if the level dropped to half but if it dropped more then half I would refill with water, add nutrients to bring it back up and pH again if necessary.... I would completely replace the water once a week..... unless I end up replacing half the water every two days in which case it would not be necessary to "change" the water because it is changed often enough already...

Hey Mark...when I lived in Asia( 4+ years) I saw 2 types of hash production. 1) was resign rubbed hash.. the other 2) was pollen hash. Obviously, rubbed is...rubbed! and the pollen hash was taking the males ...encouraging pollen growth.. and then first quality was the first "taking" so to speak.. they did not cut the plant down at this stage, only bent plant over and shook off pollen onto plastic...they could do this a few times before cutting the plant for last shaking etc...my question is have you heard of anyone successfully using their males this way instead of destroying them?...making pollen hash...true Afghani hash.. red in the north. green in the south is a pollen (he) ..it is carefully molded with water and heat between the hands of Afghan tribesman ( pressure) using hot rocks from the fire to heat etc...the pollen IS cured before this process.. just wondered ...hate to waste anything.. ps still coming to TO to see Treavor at Growitall this Fri will call you 24 hrs before.. see if we can meet.. I can (will) get written Rx from Dr confirming Med condition and permit application if my extensive file did not convince you...oh and did have 1 of my 10 NL Buddha not make it but the others are thriving.!! hope we can meet this week Cameron

WEBMASTER:  ....please call the number of Sublime cafe 416-542-1627 and ask for my cell number, as of Thursday from 1 till 3 pm I will be at 416-824-5156 try that.... I already let them know you will call, I just do not want to give everyone my cell number on the forum.... and call me on my cell.... I have never heard of this particular method and I spend some time in India running though the fields of grass 5 feet tall (good times)....  I would imagine that if the pollen contains THC (or CDC or 400 other things that get us high) then it's all good... but name: pollen is often confused with trichomes (female crystals collected to make hash), which when unprocessed looks just like male pollen, but is in fact unprocessed (what we call in Toronto) bubble hash .....

I stay to far from hydro store so i you use an ordinary close tub 18gal. as my reservoir and I've seen it done how often do u think i would have to check my reservoir to see if the ph has changed. i understand the close tub may change the waters ph but once you adjust it with ph up or down how soon after that will i probably have to treat the water again .soon? later? normal or do you not know. i have to build my own system. like i say im to far from a store and im not ordering one either. rather make my own....like i said i seen it done before. sorry if its so long but i would like some pro. advice before i get to far into it. THANKS!

WEBMASTER:  ...what I found is that you can totally make your own reservoir, hydroponics stores have it all in one place but they have no monopoly on products, all of this stuff can be bought in your average garden store... in general its best to have HARD plastic (gasoline container-type-of hard stuff)  versus SOFT plastic (NO RUBBERMAID its like a cheaper version of a cola bottle).... so when I use a garbage can (I did) as my reZ I try to get the one that's made from very sturdy and hard plastic ...and ... not THE cheapest one there is... usually the cheap stuff is so soft it will change your water every 15 minutes.... stuff made from PVC plastic is good.... garbage cans designed for heavy loads are usually made from very hard plastic, try if you can scrape something off with your finger nail, bad if you can .... I would still monitor my pH every hour for 24 hours the first time I use the new rez, since you never know.... but if it is OK I would go down to once a day .... once a day for a week and if that's ok, the stuff works...

what's going on, my seeds just cracked and i placed them in the rockwool cubes and watered them and they look like there beginning to sprout. my question is what's the lowest amount of fluorescent light you can use in your veg. room for 6 plants so that they grow big and strong enough to hopefully be big mothers. the closet is 4x2 or 4x3...i have to check again (i know that's kind of small for 6 plants but once they get a little bigger i will put them in a bigger room. im just starting out so i would rather start with a small space then move up. i read on here you can use 100watts but is that the lowest cause i cant find 100watt bulbs. i know the hydroponics store does but i would rather get it from a home depot , lowes type store cause they would be cheaper. do you have any suggestion. well thanks for your time. hope to hear from you soon

WEBMASTER:  ..100W is an example.. you can do it with a regular 40W incandescent light bulb if you want and the plants will grow..... the fluorescent lights have many different brands... the standard office type of fluorescent light comes in a half foot wide and 4 foot long frame/fixture (some are 2 feet long) and minimum 2 x 40W office light bulbs.... the frame is $30 but the bulbs lable/design/jacket should say gro (GRO, not GROW) or Aquarium-type, they usually are $8/piece and are labled as being good for plants vs. $2 or $3 for cheap office bulbs.... compact fluorescent (again must say gro or aquarium type) bulbs are ok as well... 1 bulb (@$25) can hold 3 plants no bigger then 1 foot tall, so you would need 2 of those.....  I think the office fixture is better if you have space.....

I hope you can help me out! It's about 2 or 3 weeks until picking and last week when i went to go and see how things were going i noticed a few plants had really started yellowing and looked very droopy and wilted. ( this is not just a few leaves this is a very big portion of the plant) So i carried on giving them some water and what not. Then i go this week exactly 1 week prior to when i have gone the last time and i find the few plants i mentioned before pretty much withered and and no longer yellow but brown, so these plant looks pretty much look dead with the exception of the buds that also appear to have shrunk. Now this is my worry the rest of the plants now look like the others did the week prior maybe not as drastic but definitely are on there way to it. Do you have an explanation for the cause of this, is there anyway i could help them? What i've been giving them is 15-30-15 once a week about a pinch more than half the dose recommended and misting them lightly with Spray-N-Grow. Some sort of answer or possible solution would be much appreciated as i said before im about three weeks away and to lose everything would be devastating! Thanks for having this forum available.

WEBMASTER:  ....when using 15-30-15 i would mix it at 1 ml per 1 liter of water about once a week for 1000W lights, less if using smaller lights.... if you fed the plants pinch more then half recommended you better be talking about outdoors and not indoors, as indoors they would not be able to process all the nutrients and start burning the leafs from the outside , yellowing the leafs, and shrinking the bud into a tight un-smokable bunch, it is a lose.... when I started reading at first what you describe looked like bud rot which spreads on one plants and then jumps to the other, looks fairly similar when it happens... but it does not really kill in days ... more like weeks.... the only thing you can do is to immediately rinse as much food out of the soil as you can, bathtub is handy, and hope for the best, however given the damage done I would say its a write-off... did I mention 15-30-15 is petrochemical based.... nutrients bought in a hardware store like 15-30-15 are meant for outdoor growing and you need to cut their dosage by factor of 4 ... so if for example it says on the bottle use 4 ml / L ... for indoor it really means 1 ml/L


Comments

what all do you need to grow with promix besides promix pots lights,nutrients/water and reflective growing paper (milar). any advice would be appreciated

WEBMASTER:  ....timer, pots, saucers, some thing to protect the floor, ventilation if you use bigger lights the 400W (scroll down to the bottom of that page and there is a list)...


Comments

how do you feed plants nutrients when using promix. do u just mix the right amount of nutrients with the right amount of water and just water them like regular plants or are they feed another way...cause im confused how they are feed nutrients (NOTE: when I talk about dosage of nutrients I talk about nutrients bought from a hydroponics store... nutrients bought in a hardware store are meant for outdoor growing and you need to cut their dosage by factor of 4 ... so if it says on the bottle use 4 ml / L ... for indoor it really means 1 ml/L...)

WEBMASTER:  ....once thing to remember is that you want to SOAK the promix completely until it bleeds water from the bottom... and then you wait until the promix dries completely and is feather light when you lift the pot... for a 6 inch pot it may take 2 days when the plant is big (for a 12 inch container 4 days would be best) but it may take 10 if the plants are tiny and there is no roots.... the point is to maintain this wet-dry-wet-dry cycle ... if you water the promix too often (lets say daily) the plants will wilt, but not die and/or yield little.... I add 25% of regular dosage of nutrients always .. as my base... every second time I water the plants  I add 100% but sometimes 75% when I fight mites... sometimes 50% when its too hot.... I would never give water that had 0% nutrients... you can do that and they will not die since you use promix (unlike in a hydroponics water systems where all plants would get weird on you)... but the optimum way of feeding them is to add a little big of nutrients always even if its in low quantities....

Ummm Okay im kinda annoyed, I have been posting questions about the fast pine that didn't sprout/died/ had trouble growing , a mixture of problems and I was told I could come in and get an exchange if I had the lil slip of paper, I gave the paper to a friend of my to stop by and pick up because I was very busy, and its about 5 hours by bus/train to your store just to get there. He told me that I couldn't get seed exchanged and gave me to slip of paper( receipt ) back. I don't know what's going on but the fast pine did not do well at all, and I think I'll be LUCKY to grab a ounce if ANY with the 3 plants that grew from the 15 seeds. I would like to know what happened please reply soon. thank you

WEBMASTER:  ..i am not sure what happened, generally if you come in to the store and its a policy which we had from the beginning, the staff is fully aware (whether all puffed up ready to fight ..or not) its easier to replace the seeds then to try to know what happened,  ... , did you do the fast pine indoors or outdoors... it is not an indoor plant because it yields badly, and we mark it clearly as outdoor only.. if its outdoors the season is not yet over .... if your friend wanted to get other seeds ... say ww xxx instead of the fast pine he could get may be 5 but there is a reason the fast pine is $2 per seed and the rest are considerably more.... also I acknowledge that the sprouting ratio was less then fair and I will not bring her back next season..... 3 of 15 is crappy and I have no problem mailing you 10 skunks 69... feminized and so far I had 0 returns ....

I was talking to a friend about pollinating plants and I just wanted to make sure a couple things he told me were true. First, he said that the seeds are ready after 1 month of bloom time no matter how long it takes the female to be "finished." For example, you could pick a bud off of a female after 1 month of being in bloom and the seeds in the bud would grow if planted. (I am very skeptical of this....and would not try it myself.... on the other hand there are strains that finish in 6 weeks so they may have seeds ready in 4... but again from practice I would have to say no) Right or wrong? Secondly, he said you can take a stalk that has "balls" off a male plant, put it in a zip-lock baggie and it will stay good enough to fertilize other plants for up to a year or so if kept in a cool, dry location such as a dresser drawer. (I did find information about that on one website and it said you could keep them in the fridge for 4 months.) Which is right, if either? Thanks so much. I don't know what I'd do without you. ;-)

WEBMASTER:  .. I know people who keep pollen for years, as in many years..... but you have to first shake it off into a plastic container after you dry the plant a little bit, if you take the entire flower with stem and leafs and place it in the fridge it may mold and kill off the pollen..... but hell yeah I've seen people place the entire branch in the fridge pull it out 7 months later and still pollinate the females.....


Comments

if i started growing in mid august what are the chances do i have of getting any yield......taking in account of global warming

WEBMASTER:  ..you should be seeing healthy buds at this point ready to be taken down in a month at worst.... if they do not look ready you may have too much light pollution at night and then who knows when they will finish....

Hey guys...I wanted to ask ..are the NH Bhudda seeds feminized? I mean are they candidates for mother plant cloning?

WEBMASTER:  ..they are not feminized, feminized plants do not make healthy mothers.....

Hey just wanted to ask about harvest do you wait till all the spigmas have changed colour on the whole plant from top to bottom or can you harvest when some are still white?

WEBMASTER:  ..I wait until on the average about 75% of the hair changed colour... some buds change completely and some do not, but they are ready anyways... if my bloom takes longer then 8 weeks and the hair do not look darker yet, I would wait a week and then cut whether they are ready or not....

Yeah, check this out, one doctor had the balls not to explain to me how blood pressure worked, that's is how to read your own and what it meant, He got all defensive that I was checking his knowledge. he said "Don't worry" (in Apus voice -simpsons)"you don't need to know that, just take that one ok?" I also told him to eat my ass (in Apus voice) and made a formal complaint.

Keep trying the compassion clubs ( however, one did not even return my e mails asking q's about program) ...someone else here too if you post regularly( and you should)...if all else fails.. keep trying. It IS worth it....for the medical miracle Mary.....unless you actually like being addicted and strung out on narcotics...which I am pretty sure you don't....unlike your present physician sorry.. Remember the Dr's (like him )like the regular paying monthly visits you need to keep up your addictive med's. and keep his appointment book full.

WEBMASTER:  ..I am not surprised... I maintain this forum because ... answering 200 emails a day + spam gives me an anxiety attack...and I know how the clubs feel..... they are staffed by people who are as sick as everybody else..... no one is making any money on this.... if you do you are labled a profiteer and shut down by the cops.... this club is the most legal, but is small ... this one is bigger but less friendly.... this one is a bit too hippy for me but very respectable and very legal....

The very first time I asked him about pot he mentioned the so called courses and since that time I have tried to find something about them on the internet but haven't been able to for some strange reason. :-) Sooo ... I mentioned this to him the last time I was there (this week) - that I didn't see any course requirements - and ... no response. Obviously it's just a cop-out. I have lost all respect I had for him. It just doesn't get any more ridiculous than this. Thanks for responding.

WEBMASTER:  ..there are no courses..... but I wish I could teach them....

Hi Mark; I was looking at my plants and trying to gauge there nutrient requirements and I noticed the following. The top leaves look great nice dark green but on two of my plants the bottom "rounded" leaves (they are young plants) they have some yellow on them...(the top leaves are green though...is this OK?...

WEBMASTER:  ..from your description I would say its ok... plants tent to drop lower leafs (they get yellow and die) as the top leafs get bigger.... in general there is always some bad leafs so long as the entire plant looks good....

Sorry for your troubles...find another doctor!!!!!... only two kinds..those that are physicians. they care and have compassion about their patients ..the other kind are medical business men...they are only doctors to make alot of money...you can complain about him on the Doctor rating website...and you can search for PROPER doctors ..like mine...but I would CERTAINLY change and tell him straight out he is a disgusting human being.....yes they will pump you FULL of addicting narcotics/steriods/statin drugs/sleeping pills /antidepressants etc.....but you can also complain to the college of Physicians....bad docs like these only prescribe according to the kick backs from pharmaceutical companies...they are the ones who always have Rep's in their office's ect ...Sorry again I would recommend my DR but I know he is 1000 patients over the humanly realistic number of people he can take care of. I will ask if he knows of any other DR's like him and post it here if he answers...but I wont see him till months end...possibly seeking help through the compassion clubs.. however, I cant even get some of them to answer my e mails regarding the rules for the compassion clubs....SAY THANK YOU TO SOCIETY...it believes being a drunk is cool but a joint is criminal....

I'm looking for advice from any certified medical marijuana patient. I won't get into my health issues but suffice to say they are many and debilitating. Although my doctor agrees that marijuana "could be helpful" in my situation, he will not prescribe it. "I'm choosing not to participate" (he's scared of potential consequences) he says and "I'm not willing to spend the time to take the courses required for prescribing marijuana." (I've never heard of that one but he insists there are courses he must take before he can prescribe it.) (its BS there are no courses, ask him to send me the curse outline PLEASE) Long story shorter, he simply won't help me with this and says he knows of no other doctor in our area that is willing to do so either. I've put it before him 3 times now, informing him of the liability release form and everything else I could think of ... my last visit (yesterday) he didn't even respond to most of my comments and questions so I guess he's sick of hearing about it. What can I do? Is it possible to find another doctor somewhere that is willing to help me? I know about compassion clubs (although the nearest one is 2 hours away from here) but I really wanted to go legal. I just cannot believe the archaic thinking on this subject - my doctor is willing to give me all kinds of dangerous meds, narcotics etc. but will not prescribe the much more benign cannabis plant. It drives me crazy! Sorry for the rant but I am really frustrated over this. Does anyone have any suggestions? Thanks so much.

WEBMASTER:  ....Health Canada is on an active campaign to scare the doctors into not participating, I have proof but there is nothing we can do until another legal case is up in courts around mid December ......I would assemble my medical record and hunt for another doctor, a walk in clinic would refer you to someone else.... I would go to the hospital and ask reception for a doctor with the specialty relevant to my problem, get his/her name and get a referral from an MD or a walk in clinic.....


Comments

in this site you said feed plants every 3 to 4 days. i thought you supposed 2 feed them 3 times a day while the light is on. do you use the drip system with promix

WEBMASTER:  ..I would not use a drip system with promix as the promix would retain too much water and ultimately mold the roots.... promix is meant to be completely saturated with water and then you wait for it to dry... may take 2 or 3 days... the smaller the plants the longer it takes as the roots are not big enough to take up all the moisture....... even with rockwool system I would water only once a day.... may be twice if its too hot and they dry out..... with a drip system you usually use this or pellets, and the drip line works 24/7 constantly dripping...


Comments

when using promix, what would you grow seeds and clones since your not using rockwool cubes

WEBMASTER:  ..don't get me wrong I use whatever I happen to have, but the stuff I like is the stuff that consistently works for me.... clones I cut into rockwool, because you can transfer them into promix OR a water system but for myself they go into small cups filled with promix, I used jiffy peat's but I do not like them, I can't "feel" their dryness...


Comments

mark,i have been planning on growing with a watering system but looking at your notes i keep seeing you talk about pro mix. is promix easier (definitely, it keeps your pH on the right levels automatically) then using rockwool (difficult for beginners to understand the importance of pH of water and keeping it on the right level at all times.... you make one mistake and you kill them all) , is it cheaper the rockwool watering system, (promix is cheaper just a bit more messy since its "like" dirt) will this change the result in the yield, (rockwool yields more by 20% but ... read that bit about killing them all with one mistake) size in the plant or the taste of the bud, how would you feed plants nutrients if there in soil and not being grew in a watering farm using rockwool cubes. i know when using a watering system plants get feed by feeders and nutrients that is pumped in the trey. i realy like the water farm systems but you make soil seem a lot easier....is this true. is 3x 100w (cool and warm bulbs for each set of fl lights) the same as a 300w hp light. (no, the lumens are lower) i ask that cause i hear you can use fl light in veg. instead of hp light. is that true cause hp light cost alot of money compared to fl light. do you think 3 fl lights (3x100w =300w) is coo to use in veg. (definitely is OK for veg but for bloom is a bit on a low size) .if so is 5x5 or 6x6 too big of a room to use fl lights. (yes, a fluorescent light is only good enough for 1 FOOT away from the bulb, after that there is not enough power) i seen a video where i guy said that 3fl at 100w is all you need for healthy strong mothers and clones. withy 10' plastic buckets can you grow 20 plants in a 6x6 room or that to many plants. with the promix do u have to change soil out every so often. sorry so long but you got me thinking about switching to dirt growing instead of a water system

WEBMASTER:  ..for veg the fluorescent lights are good enough but if you flower with those same lights you will notice that the yield will not be enough to justify the effort.... bloom to me starts at 400W ...HPS or MH is ok either way.... I would never bloom with fluorescent lights.... with promix you have a very large margin of error.... with a water system you have ZERO margins for error....

Just wondering if you can help with figuring the differences in yield per wattage of light used. I'll give you a scenario to use as an example: Three clones from the same mother are vegged under identical conditions and grown for the same length of time. (Let's say two feet tall.) When changing to bloom, one is put under a 400w HPS, the next a 600w and the third a 1000w. They are all in separate rooms and are bloomed for the same length of time under identical conditions - excepting the light of course. How much difference would there be in yield between the three plants? Thanks once again.

WEBMASTER:  ..I would expect to yield from 6 (pure sativa) to 12 (pure indica) ounces total on the average from a 400W....10 to 18 from a 600W, 16 to 32 from a 1000W light, the bigger the light the shorter and bushier the plants end up.... read this for a better explanation....

I have been perviewing the comments etc., in this forum. When I came upon the May/07 blurb..by the supposed police. First, this is NOT from the police..not the department anyway.. possibly a cop flunkie or cop wanna-be...but not the OFFICIAL police...they would not be so stupid and they CAN spell and form proper sentences. This is either from some retard with a grudge or possibly a newbie cop with that,"I am a new cop and I need to change the world attitude...which of course is totally Facist.( go be a cop in America) The real police CAN search internet address's through servers and would probably have already visited EVERYONE on this site...totally wasting their and our time...and being SUED by every medical user here...a quick word to those authorities that enforce....hope you never get sick asshole.....or...go suck back some stupid juice ( alcohol) such a legal and endlessly damaging substance...oh ya ..you look smarter if you are just a legal alcohol consumer....PLEASE stop wasting YOUR time and the FORUMS.........WE DO NOT CARE WHAT YOU COPS THINK OR DO...!!!! REALLY. Citizen Canada

I would like to be able to see in my grow room when the HID lights are out (sleep)....can I use a black light? will black light effect the plants considering the .."no light at all, not even a key hole" rule????

WEBMASTER:  ..I know people who use Green or Red light, I do not know anyone who uses black light, works for them I guess but I can not confirm their yield... personally I am completely paranoid about darkness and would never ever try this at home:-)....

Is it a good idea to remove all leafs from the entire plant, after the first two weeks of budding?

WEBMASTER:  ..NO.... it it not ok to remove any leafs unless they are completely dead.... she needs those leafs to absorb and process light....

to travis in n.f.l.d. , you should never post your last name.summertime or white widow should give you a good yeild. you should spell correctly because only newfies can understand what you are trying to say. anyone else won't have a clue.where are you from?

I'm older...tired of tracking down ..so I purchased a hydro unit. This is my first time. I have one female in the flower stage. I use a 400 HPS. I notice a few leaves curling under. This is not happening to all of the leaves...just a few closer to the top. Some of the tips are a bit lighter in color. I use flora nova which was recommended by the hydro store. I was told to keep the ppm around 1500. Is there an over fertize problem happening. The plants seem OK but what I have read says no. I'm sorry I did not see your site sooner since I ordered some seeds elsewhere, supposed to be female, which came in little bag. Thanks for your advice.

WEBMASTER:  ..it may be that they are too close to the light and the heat is causing this.... another problem which may cause such a localized problem is a "wind burn"... an oscillating fan that constantly blows on the leafs will make it look like the leafs are burning from overfeeding...... what is your PH , do you check... in bloom it should be around 5.2 to 6 pH....

Hi there i wanted to ask you about organic fertilizers. Have you used Grotek products before? (never had problems with them, good brand) I bought the veg which is 1-0-2 and the bloom is 0-1-2 i think. They are 100% organic just wanted to know if you prefer organic or A&B mixes? (real organics are messy, expensive BUT good, A&B mixes are cheap and work very well.... I like cheaper) Do you get a different taste in the bud if you use organic? (when leached well definitely, but its like telling fine wine apart, very difficult) They do have other products that are organic based that have higher NPK numbers but are not 100% organic. (if its a powder, its petrochemical based and I actively discourage people from buying it, not organic MAY mean Mineral Based like most A&B are....) Should what i got be good or should i look for something better that has all 3 NPK in it. (stay with it, its not what you use BUT what you learn to use.... its more important to learn when to add a little more then recommended and when to add less then it is to change brands... food is food....)  I asked before about my room and have decided to take a corner of the room and make it 6x6 for bloom with a 1000W HPS what size should my veg room be then with a 400W MH? (4x4 minimum, 5x5 if you keep mother plants) I have a spot down stairs with fluorescents 140W for clones so don't need that space in the veg room. I like to get clones to root under floro first which usually will take a week then move them up to the veg room under the 400W MH do you think that is a good idea or make the veg room big enough so the clones can fit in there too? I bought nlxskunk and G13xbudda from you could i get 8 to 10 plants in my bloom room? I also bought wwxbudda but saving those ones till after i get things going with the other 2 strains.

WEBMASTER:  ..you have the right idea either way.... you should be able to fit-in 2 mother plants, 50 clones and 10-15 young plants all under the 400W but I guess for convenience I would still keep the fluorescent lights.... not too many people have more space then necessary...

Thanks for the advice..it is greatly appreciated, The medical stuff I would like to ask about ..being new to this whole medical process ...I did speak to I think Mark( when I was in last Fri/Aug 31) and was given a phone number if I am coming in to the store T.O. ( I am presently living in Lxxxxxxx due to this last year of chemo..coming back to T.O. soon) (call 416-824-5156 and ask Dan to put you in touch with me or you may wish to deal with Dan .. either way) My Doctor has approved my Health Canada Permit to possess and grow but has not submitted it yet ..as of Aug31 anyway..you know Dr's and I imagine the Gov't still takes some time processing (10 weeks on average) as they due for disability pensions ..anything!!..etc...so my question is ...at what point to I become eligible for medical clones? (when you convince me that you are in fact medical,.... it may be a prescription with you name on it, it may be an obvious disability ... a copy of the Health Canada application, or membership in another compassionate club and there is 20 in Ontario we accept... your "proof" has to be sincere and more then just your word... ) I certainly appreciate the "benefits" of clones and quick crop turnarounds...which is important to me..being a guy wh lived the 60's..70's ... I smoke more recreationally than ALL the med pot users I know...lol

WEBMASTER:  ..according to my lawyers you are medical to me when you have a problem and are able to prove it, it comes down to my judgment..... I do not need government papers to determine if you need help, but you can see that it sure helps, .... however in a month I will be coming out with an organization which in order to operate legally will need membership to join....

i live in Newfoundland and i am growing down here and i am not impressed with the yield i am getting off my plants i want 2 switch strains and buy sum seeds off this website .The problem is i donno which kind 2 of seeds 2 use .The problem is that we have not very hot summers and they are also short can u tell me which outdoor seeds i should use ...oh yah am also looks for good thc level with good yield

WEBMASTER:  ..the only way to increase the yield in a region where you are is to force them to flower early ... you'd have to cover them for 12 hours for 2 months to induce better and quicker yield.... that would probably be true for anybody but in your case you have to do it just to get "normal" yield.... generally the heavier the indica the better since you have low temperatures,  .... white widow xxx or hindu kush.... 90% indica or more... stay away from any sativa blends... they take long (in your case too long)... and yield little in low temperatures....

First, thanks .. for all the advice/help...I bought the N/L bhudda last week (which all 10 sprouted within 1 1/2 days..wow).. deciding after reading your advice ( and that of Growitall hydroponics) to go 1000W all the way...I have them in those moss pucks for now but after reading rheams of info here and all those great pics on groups etc...I am at a loss as to what's next??....veg for 2 weeks and bloom 6-8 to get that great single huge bud effect ? or veg longer so as to produce a more moderate little bush vs the big tall plant etcc...hopefully you follow what I am thinking here..."YIELD SURE!!" that and "PRIMO QUALITY!!" is what its all about right but,.. being a brand new chemo MED guy just starting with the health canada permit etc etc...I just want to get going and give myself some stash and a great Christmas holiday...I can get more technical and more experimental next 90 day cycle( of which ,too be, endlessly more!!!!)...Thanks again guys...Cheers to Dan420 ( who I have not met/ etc but can relate to.... the .."in the hospital thing"...feel better dude!) Cameron

WEBMASTER:  ..when you do your first crop I would recommend growing a slightly bigger plant then recommended, bigger plants tent to take abuse better... in any case I would veg UNTIL they reach 1.5 or 2 feet tall (not counting the pot/container), this SHOULD take 2 weeks BUT may take more, clones would get there faster but from seeds it may take longer..... but when they are about 5 inches I would also damage (or cut off) the top 1/2 inch of the plant so she (he) would bush out a bit more.... alternatively you can do nothing and let her reach 2 feet and just put them into bloom, 1000W light should keep them bushy, try damaging the tops on 4 of 10 plants ... this way you can see the difference (if any) ..... I would rather have you learn the process first then do ANY kinds of experiments.... you will succeed when you underfeed (too little nutrients) but you will fail if you overfeed (too much)... keeping a steady watering cycle is crucial... i.e. over watering (i.e. watering too often) is actually as bad as under watering (too seldom)... not having them touch each other is also important.... just to remind that medical people can get clones from us...

Hey I posted earlier about the fast pine, If I bring my " receipt " can I can a strain that would be the same price that you know would have a better chance of sprouting? Because I don't want to keep getting like seeds and like shit happens you know ? thanx

WEBMASTER:  ..yes... never occurred to me that you would want the same strain.... same price or close enough is ok....

Im curious as to whether anyone has had any success using ladybugs as a natural mite (and bugs-in-general) predator. I have mites present but environmental conditions have prevented them from being too much of a problem...for now. spraying large mothers well enough to eliminate bugs is nearly impossible. has anyone had success in "control" (not necessarily eradication) of mites? some suppliers of bugs

WEBMASTER:  ..I try to "control" mites and do not worry about "eradication"... there is two types of predator mites (bugs that feed on mites) but I've never used lady bugs... problem is that there is many types of mites... one type hangs out on the top leafs and one hangs out on the bottoms.... you have to chose the correct predator mites for the correct mite otherwise it may not work as well or at all.. this is what I found and its very true "Among those most commonly sold via mail order are Galendromus occidentalis , Phytoseiulus persimilis, Mesoseiulus longipes and Neoseiulus californicus. Although these have been successful in control of spider mites on interior plants, effective use outdoors has not been demonstrated in Colorado. Predatory mites often have fairly high requirements for humidity, which can be limiting. Most suppliers provide information regarding use of the predator mites that they carry..".... most people who use the natural methods simply get the predator mites each and every veg cycle and let them feed .... since they do it every cycle I simply prefer to spray my moms each month.... soaking them... it seems to work... note that mites do not breed when temperatures are at 24C or below......

high Toronto420 crew!! i am curious about one of your answers to a question, regarding the use of a 100watt florescent for veg. i would like to try this amount of light for my grow. but im just wondering; HOW BIG would the plants have to get in veg, in order for them to yield the maximum i can get from a 600Watt Hps in bloom? and HOW LONG do you think it would take for them to veg under the 100W florescent? are there any max or min amount of plants i can use under a 100w floro? and lastly what SIZE SPACE do you think should be used for the veg room if it is to use a 100W of floros? i love the idea of using that amount of power for veg but im just a little unsure of its effectiveness, i just think the plants may be to small or spindly and scrawny but i don't know. i realize it would take longer to grow as well. i hope this isnt too long of a question, p.s. good luck to Dan420 for his recovery! thank you always

WEBMASTER:  ...I would have space of 4 feet long and about 2 feet wide, minimum 3 feet tall and 4 x 4 feet long fluorescent bulbs (120W)..... you can only allow the plants to be 1 foot tall thus its best if you have a mother plant and take clones.... there is enough space for 1 mother plant and 100 clones... out of which you can chose 25 best .... let them grow to 1 foot tall and transfer to 600W for immediate bloom in 3 gallon container (6 or 8 inches as long as they fit) ... because they are not as strong as if they were under lets say a 400W light its best to give them 72 hours of "get used to time"... i.e. veg them for 3 days under the 600W so they get used to it.... then bloom... support all branches with sticks sooner rather then later....

hey toronto 420 hows it going? i have asked you some questions before and always got good answers so here goes. a while ago (a month maybe? :S) i sent out a money order for 80 bucks to get a 5 pack of blueberry SK and a 5 pack white widow X buddha. so far i haven't seen any seeds in the mail and am just wondering if you even recieved the order? i have talked to the people at canada post and they said it can take several weeks sometimes if things get lost but its been quite a while and with my previous knowledge of canada post employees, im not exactly optimistic. i also had another question. i ordered a pack of 13 fast pine among other seeds in the mail around march this year. i dont want extra seeds (seeing as its so late in the season) but none of the fast pine germinated, and i was wondering what could have caused it???? I germed them in a closet at 80 degrees F in a clean glass of water overnight, and then when none cracked i moved to moist paper towel in a container. hope you can help me so i dont make the same mistakes in the future, and if you find that order, email anyone- for-tennis @h otmail .com and ill let ya know where to send it. thanks and hav a good one.

WEBMASTER:  ...I will replace the fast pine with an indoor strain, as you can see from some posts it was not the best at sprouting.... let me deal with this 2morrow.. I need to check what happened.....

Mark can we still buy your products? Pro mix BX, Pure Blend Pro nutrients, Bulbs etc? The price list page I have linked from a year ago still comes up. What's the address to the products shop? Thanks

WEBMASTER:  ...I only hook up medical growers so there is no hydro store anymore... I get my stuff here, but here is more stores....... the price list is there to help you budget when you need to buy the stuff, its more or less accurate... there is always cheaper products but if I did not use it I can not endorse it.......

Hi: I was wondering what is your understand of the government's laws regarding not paying your bill. I have a license to grow MJ through the government. While my crop was growing, I bought off the government to save a bit from off the street. I had money set aside to pay but to make a long story SHORT lost out on some funding for my autistic son to go to camp and had to use that money to pay for his worker. When it comes time to renew my license to grow, will this bill be held over my head? Will I be allowed to renew? Thanks

WEBMASTER:  ..I think you will be able to renew the license with no problem but they won't sell you any more weed... they may send the bill to a collection agency, however after this article came out Health Canada has stopped.... for how long I do not know.... the bottom line is if you simply refuse to pay it will affect your financial score but they will not really drag you to court.... if they do please let me know....  


Comments

is it possible to stress a feminized plant out enough to make it turn male??? and if so is the weed smokable if thrz not alot of seeds???

WEBMASTER:  .. some part of the plant produced male flower which pollinated itself.... i.e. a hermaphroditic plant.... it happens when ambient temperatures are too high, too consistently... over 30C is.... or if you place them way too close together... weed is totally smokable, .... however you obviously lose some yield because the space which would be bud is now taken by seeds.....

"Quote - Dan420 ended up in a hospital on brand new medications.... sorry" How is Dan420 Doing? Get Well Soon Dan420, we all love you ;) .....

In an earlier answer you said "ultimately light determines height" - just wondering if you could elaborate on that a bit. Thanks very much.

WEBMASTER:  ..I will try to explain...the outside light i.e. the sun is the base line for determining optimum or best light.... sooooo.. a 4 feet x 4 feet space outside gets 1200W (more or less depending on clouds, weather etc..) ... same space indoors can get 1000W at most, i.e. 20%(?) less then outdoors.... 600W lights gets 40% less and 400W gets 60% then what a normal plant outdoors would normally get..... the result is that under a 400W the plant keeps reaching for this light that's not there... stretching... they can get 3 time bigger in bloom then when they started ... ex. start bloom when plant is 1 foot tall but after 2 months she is 3 or 4 feet tall, that's normal for a 400W light.... this stretching adds nothing to the yield, she is just tall.... under a 1000W the plant spends less energy stretching and puts its energy into the bud itself... thus bigger, shorter buds.... I hope this helps, lets me know.... 


Comments

Mr.Urgent again....... For next year what is the best month to start growing? thanks

WEBMASTER:  ... from seeds - start sprouting mid April and by mid May the plants will be big enough (5 inches or more) to be taken outdoors...


Comments

how many plants can I grow under a 1000 watt system.

WEBMASTER:  ...if you have a hydroponics table you can do from 1 to 150 plants per 1000W.... with promix and pots from 1 till 25 ... usually 10 is often best....

I started growing a weed plant in my room (just using sunlight) in the beginning of may. Since then the plant grew to over 2 feet. I asked you before how to grow it and you said that to start blooming it I would have to put a garbage bag over it for 12 hours each day. However, I think it may have started blooming on its own, if that's possible. yes, since the outside light is in bloom mode...i.e. daylight is decreasing) It started developing v-shaped hairs along the stem next to where the branches come out of. Does that mean it's a female that started blooming on it's own? what should I do now? Do I still have to put garbage bags over it, or can I just let it be, and it will bloom on it's own?

WEBMASTER:  ...she seems female and its ok if she starter blooming,.... you do not HAVE TO put a garbage over its head but it would help to get more yield out of her of you did do that, .....the more darkness she gets during sleep the more she will yield, most people have ambient lights even at night (street lights, window lights, etc.)... most people growing the way you do would be happy to let her do her own thing.... sometimes in October she will have buds big enough to smoke....


Comments

Hey just wanted to ask what you use for veg and for bloom and if you use a bud booster? If you could tell me the NPK percentages that would be great.

WEBMASTER:  ...I use a brand less A and B formula mixed at the source ... I think the NPK is 2.5-1.7-2 for veg and 0.2-2-1.7 for bloom... in the past I used DNF, Pure Blend Pro,   ... they are all the same.... whether you eat at a fancy Italian restaurant or a Greek place you still get food...food is food you know what I mean... its how much you give them and when.....

Hi all, I am new to outdoor growing!!! I guess I am new to growing in general!!! My plants look healthy enough except for some brown leaf tips and lower inner growth dying and dropping off!!! Can anyone give me a detailed nutrient schedule from Germ. to final flowering, I am afraid I am O.D ing my plants with nutrients!!! PLEASE HELP ME??????? Dave..... THANXXXX.......

WEBMASTER:  ...either lack of proper exposure to the sun, too much moisture i.e. too much water OR you have been mixing too much nutrients.... I need to know the brand of nutrients you are using and how/where the plants are ... pot size, how often you water or how much rain you get....

Dean, thanx for info on Princess Auto. I've been looking for one of those(20X mag.). They did have them at KW Surplus, But by the time I got there they were sold out.

Dear Mark, I hope this greets everyone in good cheer. Thanks so much for all of your help. I know it takes a lot of your time. My room got way too hot and my plants stretched now I have a few popcorn buds on my plants (should have cut down on the lights but live and learn). The pistels on the top buds have turned red. The Trichomes on the top have 75 % turned colour and are ready to harvest. (at this point its up to you, you should be around week 8, been leaching for a week at least and if the hair turn colour, I would cut it all at once.... the lower buds won't gain much if you leave them.... in your case I would cut off one cola and dry it, taste it and then see its it "ready".... high an hour long means its ready.... shorter its not ready... if you fall asleep its too long) If I cut off the top buds will the lower ones grow much or should I cut them down now and start again? Would it be worth it to re-veg (no, you would need two months just to see them start growing again...its a shock to the plant) and try again or just start over (start over even from seeds is faster.... try to learn to have a mother plant and take clones... that's when it gets really faster) ? Princess Auto sells these cool 20X magnifying glasses they are about 6 inches long 3 inches wide and an inch thick. They have a light inside cost $3 and just rock.

WEBMASTER:  ...unless you get 28 C they do behave like (well) weeds.... the magic happens when they are in the zone of 25 to 28C....

Hey Mark... I have 5 skunk 69 plants growing (all 5 from the pack purchased!!!) hopefully they are all females..anyhow here my Question - during veg stage I should spray the plants all over (soak the shit out of them) to control mites? When do I start using Neem oil? regards

WEBMASTER:  ...go easy on Neem and read this first.... you can apply the 1st time, when its about few inches high.... 5 inches is when I give them a TINY MIST.... Neem being oil can choke the leafs if the plant is too hot (above 25C) or too close to the light, so lights off when spraying..... repeat in 3 to 5 days only if you know you have mites... once a month is ok when you are clean .. but who is...


Comments

Ummm your sight says that if under 7 out of 10 plants you will give more seeds or something ? :S , Ummm because I bought 15 seeds from you , 2 didn't sprout 3 died ( MY FAULT ) but with the 10 that's left If I don't get 7 females How many seeds will I get ? And how can I prove to you because im sure there's some dick heads out there that will try to jip you and lie, But bringing 10 plants to your store would be really hard lol , or is my word good enough ? PS. i still have the lil thing that says Fast pine and in pen marked 15 .

WEBMASTER:  ...in general I like when you bring the little card the seeds came with, that's the receipt, but if you don't we do make exemptions.... there is no real problem with simply stating that some seeds did not sprout and we will replace them....  in the end you can get all 15 seeds replaced, but as you said in your case some were your fault, so I guess we work on an honor system.... if I had to replace 1 out of two sales I would go bankrupt real fast... so far it has not happened.... but I do "retire" strains because quality is poor or I have to replace them too much... fast pine is not the best sprouter, and it is difficult to guess-timate how well it will sprout... but it is freaking cheap eh...


Comments

I just bought blueberry skunk, i am dying to smoke it when its ready. What does it look like at the end, about when do the leaves change colors. After i smoke what kind of mind state will i be in and what would you rated it on all time best strain you ever ever ever come across

WEBMASTER:  ...when the buds get ready to harvest the HAIR on the bud (normally white) start changing colour (to grey/yellow or blue if you lower the temperature down to 24C), NOT the leafs..... I like variety, BB SK is a 9 out of 10 in my book but even then I would smoke it for a week and change to another strain.... after a day or so of smoking the same stuff your brain gets adjusted... the only way to readjust your brain is to stop smoking weed for a day or two or change the strain your smoking......


Comments

mark i am in my vegitation stage and my question to you is how often should i check my plants and what all should i check them for

WEBMASTER:  ...lift the pot and check for dryness, should take days for pots to dry (do not over water)... inspect the leafs for mites.... dust like objects underneath the leafs, they start where the light does not reach them , turn the plants a little bit every time you see them so the whole plant gets light evenly.... clear away all fallen green matter as it attracts insects and molds.... once a day spray with plain water (i.e soak the shit out of them).... do not do that once you go it bloom....


Comments

hey mark imm more of a visual type person when it comes to learning, are there any good DVD out there or that you would suggest i watch, im growing with a watering system not soil. do you know of any build it your self dvd. thanks

WEBMASTER:  ...because the water system is so complicated I am not aware of any grow guides detailing it.... you'd think the manufactures of those systems would have something eh..... the truth is that the theory is dumb simple but the practice kills anyone but experienced growers..... there is a reason I do not touch water systems with a ten foot pole......


Comments

can u use fluorescent in veg. or do u need a 250 or even 400hp.do you need a reservoir or can u use ordinary buckets. (with promix you can use whatever buckets you want, with any other method you need to consider the type of plastic and whether it changes the pH of the water, if not sure you have to get the proper reservoir) what size reservoir do i need in veg cycle n bloom cycle. do u know how to build a grow hut. all questions are for plants 16-32 yield

WEBMASTER:  ...you can use 100W of fluorescent light in veg for up to 1000W of bloom but this is the minimum, often a 400W is perfect.... reservoir size depends on the method used... ebb & Flow has them at 120 Gallon minimum... and it goes up from there.....


Comments

hey mark i have sent you a few questions be for and you answered them but i guess i wasnt all the way clear.how long do i need to veg. clones so that they are able to yield 2lb/plt, how many 1000w lights do i need and what should my flower room sq footage be for 30 to 40 clones. want to yield at least a lb/plant. should i use 10' or 12' pots

WEBMASTER:  ...I can not help you because I have never seen anybody do it... the theory is like that.... you grow 1 or 2 plants per 1000W, usually using a grid of 6 lights, without any reflectors, bulbs hanging between plants instead of above.... plants are vegged for 2 or 2.5 months.... even then I thing it was 1 lbs per plant.... only outdoors can I get 2 lbs per plant.... as to the pots you have to use 10 gallon buckets, I think they are 20 inches in diameter...


Comments

what's going on mark, would u recommend a generator 2 avoid high bills, if not is there anything u would suggest

WEBMASTER:  ...no, even if you use a diesel generator it only makes sense once you grow 40 x 1000W lights.... economically speaking.... there is a $20K gas generator you could get for your house.... to produce 10K watts (i.e. 10 lights).... anything around 6000W per house is ok to simply pay the bills and no one would be the wiser..... a house easily has a $200 or $300 monthly electrical bill..... 6 lights is not that much more.... a sauna is 5000W, an A/C is 4000W..... as example a person living in a space consumes the equivalent of 1000W.... 4 people in a house is = to 4000W in electricity usage....

how many 1000w lights do you need for a 10x10 room or is one all you need. what's the easiest way to keep healthy plants so you can avoid spider mites an other insects, leaves turning colors and any other problems that alot of people have 2 go through

WEBMASTER:  ...10 x 10 could handle 4 x 1000W since a 1000W light can cover space of 5 x 5 feet, but comfortably 2 x 1000W is what I would want to do at most..... if you keep your temperatures at 24 C the mites will not reproduce.... so good ventilation is crucial...... overfeeding seems to be the biggest problem so go easy on them and stick to prescribed amount and if not sure, feed less.... more nutrients DOES not mean more bud...... also just because product has miracle in the lable its does NOT mean its any good.....

Hey there i asked you a few questions a couple weeks ago i think. I got a few more if you don't mind. I am new at growing but have read lots about it and re read it over and over becasue you read it to fast sometimes or u over look other thing so i find always good to read what you have read. My questions are about 2 plants i have in bloom they are growing fast 1 is indica and the other sativa. I vegged the sativa for 4 months and it is about 5.5 feet tall and the indica is about 2 feet tall veged it for 2 months The question i have is on both plants the tips of the leaves turn yellow then a brownish colour i assume it is the nutes sinse it is happening to both plants. (burnt tips means overfeeding or in some cases salt built up, since you are using blue powders I would see salt built up as a strong possibility.... mix only 10% of what you mixed before and feed  them... this low dosage should remove the salts, do it for a week) I am using the concentrated stuff 10-52-10 not the best to use i know but what i have been using sinse veg. (this stuff is for bloom and not for veg, in veg the plants need something like 20-20-20.... its not that its bad but its so concentrated that its VERY hard to mix the appropriate amounts... 1 ml per 1 liter if often enough) I took clones from both of them 4 each and 5 are alive. I have a question about them. The leaves at the top of the plants only are a light green or yellowish colour and curling upward a bit when i took them the plants were in bloom so they are switching back and have pretty much now i have them under 60W florescent light i assume again it is a nute problem i am giving them 20-20-20 samething as the 2 in bloom i am using concentrate. (20-20-20 and clones do not mix well, I would feed my clones nothing but plain water for the first 10 to 15 days... curling may mean that they are getting either too much food or too much moisture, is your dome off?) I have another if it is ok. I asked before about exhaust fan for a room with a 1000W and a 400W the room for bloom is 9ft x 11ft and 7 ft high and you said a150cfm fan would be ok are you sure that fan would be big enough for that size room or should i take 1 room and split it into 2 rooms. I read some where else that you should have a fan that will exhaust the room 3 times a minute. So maybe making 1 room 2 is better? Let me know what you think would be best and how many plants i should try and fit in to what ever size room you think would be good. I bought 3 strains from you nlxsk wwxbudda and G13xbudda. What should i use for a intake fan same thing as exhaust. (50% smaller intake then exhaust)  I am using bedrooms upstairs? Thanks for the help i know i asked a lot.

WEBMASTER:  ...1000W light can only cover 5 x 5 feet space so your room is too big.... I would use a corner, but I would not see the need to divide the room, more space is easier for working... but ultimately its your choice..... about fans: I LOVE MORE POWER.... there is nothing stopping you from getting a 300 CFM Inline fan ... the more power the better..... remember that IF you mate a FAN with a CARBON FILTER you will lose at least 50 CFM of power so you need to get something in the range of 200 CFM minimum, also for every 10 feet of travel between the fan and the actual hole outside you lose 50 CFM, a 90 degree bend in the ventilation hose loses 100CFM...... and yes a bigger room like yours may need 200 CFM minimum BUT in the end its only a single 1000W and the heat is less of an issue in bigger spaces.......

I know you can help me with this, I'm a little confused. :) If a strain you are buying says 6-8 weeks flowing time does that mean it will take 6-8 weeks from the time it sprouts to the time it is finished (NO) or is it just like it says, 6-8 weeks for the bloom (flowering) period? (exactly) I'm sure this seems like an obvious question to most people but some websites say one thing and some say the other. My guess is, the full time for a plant to grow (in this example) is 6-8 weeks bloom time plus however long you grow it before that. (you got it) Which is right? Thank you for helping us who don't know much yet.

WEBMASTER:  ...veg period is as long as you want it to be... they simply get bigger and bigger, they yield no bud and you can take clones and cut them and play with them, they can be overfed and they will recover, veg is easy...... but ONCE you trigger bloom you have two months (6 to 8 weeks as we describe it often) for the bloom to finish... you can not stop it or change it... any changes will decrease the yield, overfeeding will destroy the yield and the plants will not recover...

Hey Mark, im currently growing outdoors with an unknown purple strain, my plant is a monster at almost 7 ft, and tons of budding branches, i was just wondering, what are some of the highest yielding strains you know of for, ontario growers conditions

WEBMASTER:  ...bikers in Quebec love the strain called Freeze Land... I have seen this monster get 15 feet tall... took 15 x 15 foot space and yielded 2.5 lbs.... support the branches with sticks and rope and such, this will by itself double the yield.....

I have a number of questions for you so here goes ... If the leaves turn brown and fall off does that mean I have a problem? (YES,)  If I forget to water my plants during the bloom cycle will it matter? (you lost 50% of your yield, do it again and it becomes worthless) Can I sprinkle sugar on the dirt to make the plants taste sweeter? (no, but feel free to test this on ONE plant and report it here :-)  If I sneeze on a plant will it catch a cold? (NO) Do I have to tell my mommy what kind of plants I'm growing? (YES)  I accidentally put the fan on too high and blew all the leaves off my best plant ... is there a special cannabis glue I can buy to stick them back on? (NO) Speaking of sticking, there is this sticky stuff on my oldest plants and I'm pretty sure I didn't spill anything ... How could that happen and what's the best way to scrub it off? (Scutonium Jelly Powder mixed with Mars derived synthetic alien sweat... available at 7-11 on Jupiter) I have a male plant and a female that keep growing back together even though I cut them off ... are they trying to make seed babies? (they will be come radioactive in 5, 4, 3...2... oh well its too late) If so, can you buy condiments for cannabis plants? (radio ON for 24 hours on Heavy Metal... check Mythbusters) I couldn't resist asking you guys these questions, and I won't say any more. ;-)

WEBMASTER:  ...couldn't help myself answering :-)

What should be done in terms of bud boosters (i.e high phorphorus such as kool bloom) when growing outdoors, should it be used and when should i use it my plants hav been blooming since beginning of august, if i didn't use any wud my yeild bE REDUCED OR DO THEY NOT RELY MAKE A DIFF OUTDOOR?

WEBMASTER:  ...I personally do not use the bud booster outdoors.... in order for kool bloom to work outdoors you would need insane amount of it and its freaking expensive... indoor specific products like kool bloom are mixed in lower proportions in order not to burn the indoor crop, but outdoors the plants can handle greater amount of food, because of more sun, bigger roots, etc...... its better to get a strong (and super cheap) stuff like Plant Products 10-30-15 or Miracle Bloom Ultra Bloom (I think its 10-52-15 or 10-30-15)..... this stuff is mixed for outdoors... alternatively you could get outdoor specific nutrients from hydroponics stores... they are often organic and only slightly more expensive.....I am thinking Bat Guano or Potash mixes....

With a 400w HPS and growing 2 - 4 plants, would I be better off growing them in a 9 x 9 foot room or a 4 x 4 closet because of the extra reflective light they would receive? I've been growing in the larger room and my plants tend to be a little scraggly; I don't know if that is entirely from the HPS lamp or because of the larger room size also? I mostly grow Sativa, so, you know, Sativa and full time HPS it's hard to avoid the scraggles. :-) Is the smaller room a better choice? Rock on guys!

WEBMASTER:  ...400W light can really only handle 4 x 4 feet but when growing a sativa strain its better to have more space.... I doubt you will see improvement from moving it in to the smaller space.... if you grew indicas then it would make sense to save space and use the reflective walls..... problem with this 400W AND Sativa plant combo is that your plants will always be too tall and scraggly.... 400W can make an indica scraggly and sativas are scraggly by themselves, so unless you get a 1000W its just what it is.... you could always play with different strains to see which is more adapted to your particular problem but in the end its the amount of light that determines the height....

how it going mark an 420,how high does the cieling need to be in grow rooms

WEBMASTER:  ...I have seen it done with 3 foot tall ceiling but with air cooled reflectors and small clones set to bloom without any veg time.... generally I would not even consider anything under 5 feet tall.... even with 5 foot ceiling you are crammed.....


Comments

how can you produce 2lbs,bout how wide do indica plts grow so i can determine the size of my rms,dnt want leaves or branches to touch

WEBMASTER:  ...it comes down to experience.... by following the guide you could get a pound but on the next cycle you can always play with things like A: adding more nutrients  B: spending 2 days extra in veg to get that extra inch or two C: lowering the temperature D: supporting each branch individually with a stick E: ...etc.... my rule of thumb is that once the plants take over 80% of the available space without touching I set them to bloom... they still grow for two weeks in bloom so they will take over the rest 20% of space.... if they touch afterwards its ok..... as example of too much veg time would be ... if my plants are touching when in veg then they will only get worst when set to bloom, thus they will get stressed out, bottom branches will get no light, mites will move in and the yield is toast....

hey 420 and crew, i have 2 questions, 1.i have a closet that is 4ft by 7.5 ft, i wanna know should i make this my veg. rm for my mothers or my fl room 4 clones, 2.i also wanna know if this is my veg rm, how many mothers should i fit in my closet if this is my fl rm how many clones should i fit in there. thanks for your time

WEBMASTER:  ...this room could handle a 1000W light for bloom or veg with proper ventilation.... but with veg I would probably get a 600W or 400W MH, ....I would keep up to 3 mothers and use the extra space for clones and smaller plants.... with bloom I would get 15 x 4 Gallon (8-10 inch) pots, 1 foot high and bloomed.....


Comments

wats tha most you heard of bb skunk yielding

WEBMASTER:  ...if my best yield in promix tops 2 lbs  per 1000W (NL SK or WW XXX)... then I would expect 1.5 from BB SK..... blueberry is a sativa and not known for high yields.... skunk gives her a lot of help but its still relative of course....  


Comments

Hello 420 Crew! My question is this: Are clones that are taken from a host plant that is in bloom always put into bloom themselves or can you put them in veg? Have a great one!

WEBMASTER:  ...you chose the cycle for them so a clone form a blooming plant can be transfer to veg room and it should readjust..... if the blooming plant is longer then 2 weeks into bloom the cloning may be a failure or the clone may take a month before rooting... you can only take a clone up to two weeks into bloom (for outdoors its more like a month or two)

Hey I bought 15 fast pine seeds , 13 sprouted , 1 died. So there was 12 and like 1 of them is a different strain. it started with purple leaves then they as it grew bigger the purple faded , but then I realised it was some sativa strain , and the fast pine was indica , :S I thought the fast pine would've been sativa but it didnt specify on the sight. What could this unknown plant be ?

WEBMASTER:  ...I will be the first one to admit we do fuck up here and there but I have no purple strains ... purple happens due to either too much nutrients or low temperatures..... as to the mystery sativa strain.... I really do not know but am curious my self....


Comments

was using miracle grow on the up untill they started to flower....now im giving them kool bloom...should i continue with kool bloom?is that whats aking them yellow?otherwise they look real healthy...im growing in a huge pot in soil behind my house.

WEBMASTER:  ...yellow means lack of nitrogen.... kool bloom should be used with conjunction with another regular bloom food, BUT not by itself.... there is a miracle grow for bloom..... if you have none I would mix a little bit of the whatever miracle grow you got and give it to the plant, the leafs should gain a nice green colour..... I would start using the kool bloom a bit later when buds are well defined....

Hello - Mark, Dan or anyone ... I won't bore you with the details but an unexpected event forced me to put 4 clones into the 'bloom room' at only 2 weeks old. I expected them to only be there for a few hours and then return them to veg, BUT, a whole series of things happened around here and they ended up getting left there for 3 days so far, almost 4 now ... well, they are blooming already! Now I don't know if I should just leave them or try and return them to veg? They are 2 weeks old as I said and about 8 inches tall. They are a Sativa variety. What do you think? If returning them to veg obviously I need to know asap. I'm really torn on this one and could use some good advice. Thanks so much.

WEBMASTER:  ...you stumbled on to a disaster.... you can bring them back to veg... lights ON for 24 hours instead of 18..... you actually have two weeks to stop the bloom once you start it.... problem is that this is a major shock and some strains respond to this type of stress better then other... chances are the will recover but the question is HOW long will this take..... it may take a week.... but it also may take two months...... Dan420 ended up in a hospital on brand new medications.... sorry


Comments

hey mark i have two small plants that my buddy grew from a seed 3 weeks ago would it be a dumb idea to plant them outside ??

WEBMASTER:  ...a bit late now but you can still try.... they won't get big (because outside the cycle is on bloom now) but they should start budding..... if frost goes easy on them you may get some bud for sure around October.....


Comments

I have a large mirror (4' x 5') I am considering putting on a wall in my grow room. Is this advantageous or should I stick with the flat white? I've tried to find the answer to this but there doesn't seem to be much info about it. Thanks very much guys.

WEBMASTER:  ...mirrors reflect visible spectrum of light BUT NOT the growing spectrum of light (which you want) thus a flat white surface is MUCH MUCH better then a mirror....


Comments

didnt think i needed to add nitrogen....there starting to flower so im giving tthe kool bloom...i stopped tho..there just gettin straight water now

WEBMASTER:  ...kool bloom if an additive on top of regular nutrients..... you still need to feed with regular nutrients, they may not need a lot of nitrogen in bloom but they still need some.... also, always add a little bit of nutrients even if they need "just" water..... that little bit of food with actually leach out old salt deposits in the roots better then pure water... I add 10% of normal food but anywhere between 10 and 30% is fine.... it has an added benefit of preventing the plant from locking up (when you give plain water the plant may actually "think" it will get no food in the future and retain every bit of nutrient thus will not leach but burn ... this is called nutrient lock and can only be solved with low dosage of nutrients)


Comments

Can you turn a clone into a mother? My mother is getting to bushy so I'm thinking about flowering her. This will give the baby clones more light and room.

WEBMASTER:  ...of course... all my mother were clones once.... the best mother is one that is one clone away from seed...... BUT genetic drift is highly exaggerated and you can take a clone of a clone of a clone of a clone...etc... 25000 times before the strain gets weak....if she gets too big because you already have clones cut the mother down (with scissors).. just like you would do with weeds..... she will re-grow bushier and stronger....


Comments

How thick or how thin can a clone be? Also, can a clone with more than one shoot be rooted? (sure) I hear growers say to take clones from the bottom of the plant so air circulation will increase. (I am not sure it matter where you take the clone from, with right humidity and temperatures I can make any clone live well) However, the bottom branches are very thin. (they may require a longer period under the dome to get more humidity but overall it matters little) Some plants such as white widow have long delicate branches. Are these plants more difficult to clone? (long and thin means the clone hads to spend longer period under the dome, say 3 days instead of 2, and may require more spraying with water, say twice a day instead of once, they generally take longer to root, 12 vs. 10 days for something hardier) A few weeks ago, you stated that you would contact the supplier about why your "White Widow XXX" is only 10% Sativa when the true pure white widow is mostly sativa. Also, what is this "Indian XXX"? I am still waiting, your answer determines weather or not I will purchase this particular strain from your company. Thank You.

WEBMASTER:  ...I take huge issue with (pure) White Widow being "mostly" sativa.... when I grew a pure White Widow, she had slim leafs (bit not the slimmest) but was very bushy and short.... she may have some sativa there but if she was "mostly" sativa the bloom period would be MUCH longer and it isn't and the smoke felt "sleepier" then a pure sativa.....  then again we could also argue who actually sells a Pure WW and we all take someone's word as "fact".... XXX is a strain developed by Ontario's Best and other that then I know little about her, but its a heavy indica all for yield..... WW by itself is not a good yielder (comparably) so she got mixed with XXX..... also remember that I read stuff out there and then I smoke it gather opinion and then write about it..... I really do not trust most websites talking as if they knew it all...... sorry but Dan420 (who answered your question) got sick (hospital) and that's why there is a huge periods between answering OR complete lack of response..... either way the WW XXX cross is about yield and not taste..... not that it tastes like shit but just like wine.... the taste could use more depth or refinement (high) and less numbness (stone).....

hey 420 nice website.i have a trey and a plastic dome that i got from a buddy of mind,its used...nothing wrong with it.its just use.how do i clean my equiptment and other materials to make sure there 100% clean and ok for my plants. hope to hear from you

WEBMASTER:  ...warm water does the trick... since you have to remove potential mite eggs plain water works just fine.... if you are really paranoid you could add a spoonful of bleach to a gallon of water and then use that to clean... bleach kills all... good...


Comments

if you need a big plant trey, can you substitute it with something else thats alot cheaper,can you buy something else or make your own,i know how to build a hponic system but i would like to kno whats the cheapiest way but safe (for me and my plants) to build one.i kno you may say look at a link on your page but it really doesn't tell you what to buy to be safe but cheap.1st time grower...dont wanna waste a bunch of money and not even turn up with anything to smoke, thanks for your time

WEBMASTER:  ... you must shell out the money IF you want the hydroponics "system"... because they use special plastics to make sure the plastic in the equipment does not affect the PH of the water... if you build your own from Home Depot parts your PH will change constantly and you will never be able to determine which part is causing you problems, not that it can not be done, just you most likely do not have enough experience ..... that is why I only teach about promix... it is THE cheapest method, you need dirt (promix), pots and light.....


Comments

what are all the nutrients you need to get the best quality, i know its like grow, micro, and bloom or something like dat. do i need anything else or do you recommend any other nutrients

WEBMASTER:  ... I hate the 3 plant formulas (like grow, bloom and micro) because there is 3 bottles to content with.... I prefer ANY brand A and B formula which is actually 4 bottles but you use 2 for veg and 2 for bloom..... also I like the organics like Pure Blend PRO or Flora Nova (single bottles BUT you MUST shake bottle before using).... stay away from anything that is powder and BLUE in colour...... I do not like any other nutrients because there is NO miracles.... there is only people who want to  sell you miracles....

420 i been smokin for about 2years and want to start my own gr room, how many plants can you grow in a 64sq foot area if your growing with 10 inch diameter pots. the strain is indica so they will be bushy, what's the top number i can put in this area and what's an amount you would suggest. I jus bought from you (bb sk) and (jf x nl x sk), what kind of yield should i expect if i have a 600 or 1000 watt light from each plant of each strain. how big should you grow a clone be 4 putting it in the fl rm so that it produces the very max it can, i just read you can get 32oz out of one plant ,is that possible an if so how can i do that

WEBMASTER:  ... this area could handle 4 x 1000W light but I would not do more then 3 lights..... read this section to see what makes a yield.... you could probably do 5 plants per 1000W light with 10 inch pots.... you can get 32 oz. outdoors but I have seen it indoors done only ONCE..... you would have to have the plants 6 feet tall..... and 2 plants for every light..... long veg time (like 2 months) and its highly inefficient (indoors).... 4 clones under a 1000W would have to veg for over 3 weeks minimum (more like 4 or 5 if you are less experienced)..... to pull out maximum yield involves experience and there is no magic bullet....


Comments

after determining sex and you have females...how many clones should you snip from mother plts once there old and big enough

WEBMASTER:  ... a 4 month old mother plant should produce 50 clones every week.... 100 if done well.....


Comments

1000watt

WEBMASTER:  ... best to have 5 x 5 feet space, a ventilation fan that can pull 150 CFM (Cubic Feet per Minute).... a 1000W light is as much power as a small heater so you are not a "gro-op".... electronic ballast saves power buts they're freaking expensive.....


Comments

how many lights, filter fans do i need for 30 to 40 fems, how many sq ft do i need my fl rm to be, how can i keep bills lo

WEBMASTER:  ... read this bit ... it explains the yield..... I can grow 40 x 1000W lights and 40 plants BUT I could also grow 200 plants under 1000W light..... its a bit more complicated then that....


Comments

sorry for this but last note i asked about what size hood do i need to use, i meant a standard hood you would get when you buy a 250 watt hp system or do i need the big umbrella one or does it not matter, ( I literally use whatever reflector I happen to have so it matters little to me...+ the 250W reflector is pretty much the same as 1000W refector) i also have another question, i don't want to pay all that money they charge you at the store for a reservoir, i heard you can use an ordinary close tub (like a 15 or 20 gallon) but i also was told there not good to use caz after a while particules break off from the tub in get in the water. how do you feel about that and if they no good to use what can i use to avoid paying store price.....what about big plant treys. thanks

WEBMASTER:  on the reservoirs issue you want to be careful.... if you use promix as your medium, it matters little what kind of plastic you use... but if you have a water system (rockwool , ebb&flow or such) the plastic in the reservoir could change the PH of the water so cheap plastic is OUT..... promix buffers bad PH but in any other system you have to make sure the plastic in the reservoir does not change the PH of the water, ...... there is no easy answer....


Comments

hows it going, i have a couple questions. i am in the process of starting to build my grow room, i have one 1000watt light system....my questions are 1.what is the max. square ft i should build my flowering room when im only using 1 1000watt system (it can be done with 4 x 4 feet minimum, 5 x 5 is the optimum space for the plants so I would TRY to get 6 x 6 because you want to have easy access to every plant ... that extra foot is your walkway) 2.how many plants can i grow in my flowering room so they all grow healthy and bushy and not stretch (i have 80% indicas) (5 to 8 plants in 5 Gallon containers is the easies method, but nothing stops you from having 50 of them in 0.5 Gallon containers...)  3.what size hood do i need to make sure all my fem. get enough light, can i use the standard hood do i need the build umbrella (I like 36" umbrellas I find 42" umbrellas too big, but in the end any reflector is just fine, you can even make it yourself as long as tits either flat white in colour or aluminum) one and my last question is 4.do i need a hp light system in my veg room or can i jus use fl. lights. i kno i asked for alot but im a beginner who wants to avoid messing up and wasting money. thanks for your time

WEBMASTER:  with a 1000W in bloom you should have at least 100W fluorescent in veg, you will need a bit of experience to synchronize the two since the 100W fluorescent grows far slower then the 1000W.... but if you have mother plants I would get a 400W MH..... easier to make the mother plants happy


Comments

hi,mark, i have a problem, i have 2 very nice female mothers (bb/skunk), i cloned them in march, planted the clones in may (outdoors), looked at them a few days ago,they look like like males with pollen pods starting to form. my question is,could stress of any kind turn my female clones into males, i have not seen anything like this before, plese help!

WEBMASTER:  Stress can turn you plants male... to be precise a HERMAPHRODITE ... the plant should look mostly female with some male flowers... but NOT ALL MALE... that would be very weird..... very bad PH in the soil could stress them a lot.....


Comments

in regards to unhappy customer ive had both breeds and was very impressed. i had nl/s before and it remains my favorite breed the smoke is beautiful and it produces very tight havey buds. ive searched a long time to get this breed again. thanks to 420 i now have nl/s and skunk 69. stick with these breeds and you wont be disappointed. they don't call it wheelchair weed for nothing

WEBMASTER:  ... no worries, people have their expectations and desires and they may conflict with reality.... in any case anybody can feel free to "bitch" here... that's why its a free forum :-)


Comments

hey mark have you ever heard of critical mass if so what have you heard got some seeds from some weed and it grew fast. mainly sativia but is looking good and outside it started budding in late july should be ready at the latest mid September. let me know if you have ever heard of this breed please ive never heard of it before and was wondering if anyone else has

WEBMASTER:  The critical mass I had was definitely not a sativa so we may be taking about two different strains..... but also I never tried her outdoors so you may be able to tell me something new here....

I want to use (2) 400W set ups...(1) high preasure sodium for flowering and (1) metal halide for vegging "combination" ----- Will this give me the same grow power as a ***800W bulb???? ****( if there was such a thing)???----- I need minimum 600W because I want 8-12 ounces every 2-3 months but we cant buy (2) 300W h.p and/or m.h.for the light spectrum mix.... Please advise I am late in buying my lights and the clones need them now !!!!!! Thanks.....

WEBMASTER:  If you have 400W for veg and 400W for bloom you still only have 400W of yield..... I would go with a 1000W for bloom and a 250W for veg..... vegetating period does not need as much power as the bloom so the bulb can be smaller... in fact 100W of fluorescent light would be ok... you should be able to get 12 ounces from a 600W HPS light in bloom and 250W light in veg.......


Comments

Hello.. I am in the process of buying a grow light ... should I get a metal halide or high pressure sodium? Thanks

WEBMASTER:  The very first light should be an MH, fuller broader spectrum.... if you get a second light get an HPS......


Comments

The Link to" used equipment" is down (Errorpage) is this temporary?? I would like to try used equipment first.

WEBMASTER:  ask me here what you need and I can see what is available..... the page is down? ... problems never end indeed....


Comments

I wanted NL but got NL/Skunk, now I only got skunk plants. If I wanted skunk I would have asked for it. Theses genetics are not working or your seeds are not good. A very upset customer

WEBMASTER:  we never claimed with had PURE Northern Lights.... Its a NL x SK cross.... I am sorry you are upset ..... If you were medical I could help you further with clones but even then I do not have a pure NL as a mother.... also which NL are you looking for there is at least 5 I am aware of.....


Comments

I was told the 400w lumens lights ..that are available from electrical stores ($120.00 - ballast and bulb combined) are equal to the 400w h.P.s or m.h. ? Is this true and if so then 2 lights can equal grow power of 800w ??

WEBMASTER:  The ballast HAS to be able to run a MH (or HPS) bulb .... i.e. if the bulb sold with the ballast SAYS HPS or MH right on the bulb then yes its the same thing ... make sure its not a Halogen 400W (or any other).. they emit heat instead of "good" spectrum of light....... 2 x 400W = 800W indeed .....NOTE: some if not most electrical stores sell the ballasts UNWIRED.... Hydroponics store takes that ballast, wires it and puts it into a nice metal box so we don't get shocked ... but its the same thing in the end....


Comments

Thanks for the info, the only other question I would have right now is concerning the least odourous variety??....others seem to ask this too so I am watching the answers...would Fridays (after 12) a good time to come in for questions?? I have to come for seed packs. (ie Aug 31)You are right next to my hospital.... T.O Western. Thanks again

WEBMASTER:  I general pick a strain that has BUDDHA in it..... Shiska x Buddha or White Widow x Buddha or Summertime x Buddha.... these plants with higher Sativa ratios smell far less..... Aug 31 is a Friday... we are open :-) NOTE: if you have a medical issues (and we would need some proof) you can buy clones from us..... only if you are medical.. clones are easier to work with then seeds.....


Comments

When you cut the top off of a plant, can it be planted as a clone? Thanks.

WEBMASTER:  YES... of course.

I asked about HPS lights below and you mentioned you'd like to know what brand it is to be sure it was decent ... it's a Philips bulb and the packaging says "Alto" - I guess that makes it a Philips Alto. :-) I know Philips makes decent bulbs so I'm not worried about that, I was just wondering if a top notch bulb makes that much of a difference. Doesn't sound like it ... Thanks!

WEBMASTER:  the alto is a "basic" bulb.... i.e. its good for 1 year.... I used it and had no issues.... a "better" bulb would a Hortilux brand or SunMaster.... they generally have 30% more lumens..... which is good but weather its worth double the price of the regular bulb is doubtful.... as example I do not bother with the better brands .... i would rather replace my regular bulbs 3 months earlier rather then spent the extra on the "better" bulb...

Hi I purchases some of your fast pine seeds ( 15 ) for just a lil something for winter. And 13 sprouted( wich is great and all ), But as I let them grow on of the seedlings is about a few inches tall now and It's 2 bigger jagged leaves is purple for some reason ? Could there have been a mix up with the packaging ? Also what do I do if one of the plants has Yellow leaves ? thanx

WEBMASTER:  Purple may mean two things.... its too cold (this being summer I doubt its true).... overfeeding (too often too much)... but when someone tells me they see yellow leafs my first reaction is to say "feed more nutrients"..... I would be careful because stress also causes yellowing of the leafs..... the most common problem I see is that new growers over water the plants and in some cases underfeed ...... allow the soil (less) mix to dry out completely before re watering again... also try adding a bit more nutrients to a plant or two (test it and see if the yellowing goes away)....

i ordered seeds about two weeks ago and i still haven't got them. I live in Oshawa and paid with credit card.

WEBMASTER:  ....sorry I had a problem with re-supply.... we do not keep all the seeds in one place because we are worried about B & Es ... everything that was late went out last week... Friday the 24th...

What's the best hybrid to use if someone has odor issues during flowering ? Plus the heavy couch type suits best with the shortest cycle?

WEBMASTER:  In general terms the sativa strains are easier on smell ... anything that has BUDDHA mixed in it should be far less smelly then for example SKUNK..... also the more Indica the strain the quicker it finished the cycle.... sativas take their time...

I was just wondering Fast Pine being outdoors only, If just sprouted ( 2 little leaves only ) , is it too late this summer to expect bud before it gets too cold ?

WEBMASTER:  It is too late to grow outdoors now, in my opinion. But don't be disheartened, you can grow indoors with even a small closet! Best of luck, URGENT!

i want to grow some weed in a airing cupboard is it essential to have lighting its a hot room but there is no room

WEBMASTER:  I don't quite understand, but yes you do have to have proper lighting to cannabis plants to grow, in the proper spectrum, which is why growers use high-pressure sodium and metal halide bulbs.

Hey I am first time grower, I have germinated my seeds. and planted them in soil, they sprouted from the ground now and I plan on putting them outdoors. Should I put them outside now or should I grow for another week or 2 inside. if inside how do I care for them ( light cycle . ) with out killing them.

WEBMASTER:  I wouldn't put them outdoors now, to be honest; it's too late in the season now for starting plants outdoors. I would invest in a grow light kit and grow indoors until next spring/summer. You can get great results with a relatively inexpensive 400W kit, and what you learn from growing indoors will help you next year outdoors. Best of luck, URGENT!

Hey there just have a question about exhaust fan. I have 2 rooms i am going to use 1 for veg. and the other for flowering. 1 room is 11ft x 8ft. and the other is 11ft x 9ft. My question is what size fan will i need if i use the 11ft x 9ft. room for flowering and have a 1000 watt HPS in there and the other room has a 400 watt MH would you need 2 fans the same size or 2 different ones becasue the temp won't be as high in the room with the 400. One other question what would you use to cover the walls and floor with my floors are hard wood? Thanks for the help.

WEBMASTER:  Sounds like a nice "constant harvest" set-up you have planned, 420man. What I need to know is how many lights you'll be using in the room, because the more lights, the hotter the room will get. Sounds like you could easily get 2 lights per room easy, if you wanted to. A good guide for fans is to use 150 CFM (cubic feet per minute) fanpower for every 1000W light used in the room. For the 400W, since it's always better to have more ventilation than less, a 150 CFM fan or close will do great as well. So invest in two 150 CFM fans and a carbon filter for the bloom room and you'll be good. To cover your hardwood floors, use a product called "black and white polyfilm". Here's our description of it from our grow guide:

"You can buy a (so-called) Black and White Film, called B/W Poly Film. You have to get this from a Hydroponics Store. You will need a piece the size of 10 feet by 10 feet, should cost you under $20. This is heavy plastic film which is Black on one side and White on the other. This is a very good material because its 100% light proof. No, garbage bags do not work, and you can not find this anywhere but a Hydroponics store. The sides of the closet should be covered with Black & White material which will provide you with optimum reflection of the light. When you line up the closet with this material, make sure that the White Side of this material faces the inside of the closet. The FLAT WHITE colour is the best reflective material out there. Aluminum foil or Mirrors will not do as well as Flat White."

Best of luck, 420man!

Sorry I forgot to mention grow method. I am currently using Fox Farm Ocean Forest soil with additional perlite. Clones are grown in cocoa fiber cubes.

WEBMASTER:  Fox Farm has nutrients in it, so your plants may be getting over-fed. I've always used Pro-Mix BX, there are no nutrients in it so I can have much more control in how much I feed the plants every watering.


Comments

I'd like to share some success results with everybody and also see if you can offer some additional advice. Veg is currently under 45W fluorescent bulbs. space is 1.5 feet by .8 feet. Bloom starts when each plant is 6-12 inches (depending on the variety) and they are bloomed under a 1000W HPS bulb in a 4 feet by 2 feet space. First 2 weeks of bloom I use Dyna Bloom (3-12-6) and I then switch to a combination of Tiger Bloom (2-8-4) and Super Bat Guano (1.5-1.5-1.5). When plants require food, they get Tiger Bloom and when tips of leaves get brown I use the Guano and do this until the second to last week of bloom. Then they get properly leached and 1 week later harvested. At this point in time, the taste and high are spectacular but I am only yielding .75-.9 ounces per plant (clone or seedling). I do not have much space (8 square feet). Do you know of anything that I can do in order to increase yield without sacraficing quality (taste and high) while keeping the plants the same size (a way to increase the yeild of the buds that form lower on the plant)? One additional interesting observation is that I noticed my plants which are hermies (male flowers that form inside of the buds) stopped pollinating when I began feeding the plants guano on week 3 (my guess is that it is due to the vigorous trichome production starting towards the end of week 3 when the male flowers begin to open). Is this something that you have seen before?

WEBMASTER:  Hmm, space restrictions are difficult but not impossible to get around. You're using the "sea of green" method, so don't expect too much of a yield per plant; however, to increase yield: how hot does your closet get with a 1000HPS in it? I'm a bit worried the room may be too hot, causing the plants not to respond as well as they should. Also, look into feeding solutions commonly referred to as "bud booster". You feed it to the plants towards the end of the bloom harvest to give the buds an extra boost in growth. It also sounds you may be over-feeding a little bit with the Tiger Bloom; remember, over-feeding is a very common problem! I would also get those hermaphrodites the hell out of the grow room, because if/when they pollinate they will pollinate the other plants in the room and those plants will stop producing sticky bud.

Hey Mark and the Toronto420 crew! Just curious if you have any pictures or a grow log on the Juicy Fruit x strain. In particular, I'm looking for pictures of it in flower. I have 10 monsters outdoors and are in the first week of flowering; looking top-notch so far! I've been taking pics regularly and intend on sharing them with you folks when all is done and harvested. Thanks, Mo.

WEBMASTER:  I'll ask some of my friends if they have any such grow logs, and I'd be very interested in seeing yours! Sounds like you're going to have a great harvest, Mo! And yes, please send us pictures, we love seeing other people's crops from our seeds!

ive noticed the leaves on some of my plants are yellow...whats that from?

WEBMASTER:  Most likely lack of nutrients, especially nitrogen. What system are you using to grow your plants, what are you feeding them, and how often?

Hello, I was wondering if you could tell me why a clone "collapses" when it is put under flourescent light, even at 12" or more away from the light. I recently took 4 clones, all look very healthy and are starting to add new vegetation to the top of the clone, BUT, whenever I put them under flourescents, 2 of them collapse as if they've wilted. I've tried it twice and both times they have come back to life after removing them from the light but I find this very odd. Reight now they are in a bedroom, existing off of the natural light that comes through the window but it's time to get them into a better lighting situation. Any ideas? Thanks very much.

WEBMASTER:  That's a very common thing for clones to do; the cutting is stressed from being removed from the plant and needs some time to recover. A good technique to get around this is to keep a plastic dome over your cuttings for about a day; it will be very humid under the dome and the cuttings won't be as stressed. But remove the dome after a day (or two) because the cuttings will of course need to breath. For a better lighting situation, you can use put the cuttings on the periphery of your HPS or MH grow light, not under the light but off to the side where the light's "border" is; as they grow bigger, move the plants move and more under the light. Best of luck, Greg!

I just transplanted my clones into a ebb and flow bucket system and started week one of the feeding program. They have been growing fine for about 6 days no but I've noticed in the past day or two that the new growth on the top of the plants is pretty yellow. what do you think is wrong? It has been getting pretty hot in the room.

WEBMASTER:  It sounds to me like the over-heating in your room is causing your plants to not uptake nutrients and oxygen properly. Your ebb & flow solution should be at 60 - 70 F; any higher and it won't hold as much oxygen and could very well lead to disease and bug infestations. Check the temperature of your water, you may have to cool it down or ventilate the room better.

Hello, This post is not about seeds or growing... Me and my fiancee have been engaged for about 4 years and we are FINALLY ready to tie the knot. We would like to get married in Queens Park, on April 20th, 2008, @ 4:20pm. The problem is we need someone to marry us. We could pay $350 to have a JP form city hall do it, but would prefer someone who would actually enjoy and understand the reasoning for our chosen time and place. If anyone out there is, or knows someone who is registered to perfoem marriage ceremonies please get back to me. I know this a bit of a weird request but it's my wedding and I can do what I want lol. lil_xxx_angel@hotmail.com THANKZ

WEBMASTER:  Well, I'm a registered priest with the SubGenius Foundation, but I don't think Canada allows me to marry people. You could try joining some of the more popular cannabis discussion forums on the 'net, especially http://forums.cannabisculture.com/forums/ubbthreads.php , and post a message there, it's a very popular cannabis message group. Congratulations on your upcoming marriage, Lisa! Great day and time, too :)

i was just wondering i purchased some nl X skunk from you guys an some white widow buddah , my plants are 6 feet tall for the skunk an 7 1/2 for the white widow . like these plants r spectacular lookin an there just starting to bud i was just wondering if they will finish on time seeing how its augest 17th. cause it be really sad to see them go to waste, all my other strains form other seed co are budding or r almost finished i would just like to know if they can finsih in the maritimes wehere the weather isnt the best in the fall , im just worried bout bud rot. thanx was just curious would just like to see the girls reach there full potential

WEBMASTER:  Glad to hear your plants are doing great! Yes, right now I would be quite concerned about your plants blooming on time, before bad weather sets in. You should check the weather reports daily, from two or three different sources, to get an idea of how the weather is going. We've been blessed with a hot summer, so hopefully it will last for awhile. Still, it could be very close for you, unfortunately, and if the weather turns bad you may have to harvest early. However, Northern Lights is an Indica oriented strain that has a 7-8 week bloom period; with some luck with this hot summer, you just might be able to squeeze out a good harvest. Be optimistic but don't raise your expectations too high. Best of luck my Maritimer friend!

Hi Mark how ya doin. I was just wondering how many parts per million of nitrogen you would use on clones, veg, up to 4 weeks in flower, 4th thru 6th week of flower. Could you please help me on this one. I cannot seem to be able to find the answer, but I bet you know. Thanks again smart guy and I hope your feelin better.

WEBMASTER:  Sounds like you're using a reservoir system.  A standard range limit of Nitrogen PPM is 150 - 1000, with the average being 250. Of course, you'll always be "eyeballing" your plants for over-feeding/deficiency. And thank you for the kind words, Phil!

Sorry for the double post, I was unaware it happened. I should mention I'm growing in a closet. I will be using CFLs for veg, and a 250 watt HPS for bloom. I only intend on growing 2-3 plants at a time for personal use, otherwise I would get a 400 watt, and probably eventually will when I have the money for it. When it's time for to install the HPS, I intend on getting a small in-line duct fan. Because I am growing in my bedroom closet, I don't want to use any ducting. You said this in your grow guide: "This fan can also be attached directly to the hole without any ducting." I know it may seem like a stupid question, but I have no experience with ventilation, so I'm wondering how I would attach it directly to the wall, and what I'd use to cut a hole into the wall? Do I need a flange kit, or is that only if I'm using ducting? Sorry for all the questions, but I know you can help. Thanks.

WEBMASTER:  Hi HB, no worries about the double post, I fixed it. Sounds like you have a nice little grow closet planned! Yes, eventually you will want to invest in a 400W bulb, they give a lot more bang for the buck than a 250W. About mounting your fan: if your walls are made of drywall, get a drywall cutting saw from the hardware store. It's a tool you poke into the wall and saw a section out to create a ventilation hole. Also buy some fan mounting brackets, or there are metal straps you can use to hold the fan onto the wall. It's actually quite easy, and you shouldn't need a flange kit.

Hello. I'm so happy I found this website. I kept spending money on the wrong types of soil, only to find out it wouldn't be for the best. I intend on using GH FloraNova Grow and Bloom as that's what I purchased, and was advised that the soil I was using would make growing my plant a pain in the ass due to it already having nutrients in it, and it would lower the pH, etc... So, I have decided to purchase Pro-Mix BX. Unfortunately it's too late in the season to purchase it at Home Depot so I'll have to find it elsewhere most likely online. I found (online) Pro-Mix BX with BioFungicide and Pro-Mix BX with Mycorise Pro. Are those alright? Or should I look for the one in the black bag? My local hydro store does not have Pro-Mix or Sunshine Mix #4, but has Sunshine Organic Planting Mix. If I can't find Pro-Mix would that be acceptable to use? Here is what is said about it: "Organic Planting Mix is perfect for giving your plants a healthy and natural growing environment. Use it indoors and out to start seeds and grow flowers, herbs and veggies. Organic Planting Mix contains Canadian Sphagnum peat moss, perlite, dolomite lime to balance the pH of the ingredients and a wetting agent to improve moisture absorption." Do I need to add perlite to Pro-Mix (or the Sunshine if it's okay to use)? I'm also wondering how I should I feed my plants. Should I feed, water, water, feed, etc...? Or feed with every application? Thank you in advance.

WEBMASTER:  A growing medium similar to Pro-Mix will work fine. This may surprise you, but I've found Pro-Mix and similar growing "soils" at Wal-Mart and Canadian Tire! About feeding: I always go with the "eyeball and lift" method: I examine my plants everyday and gauge the amount of food (or leeching) they need by their appearance. You want a dark-ish green, vigourous appearance in your plants generally. And I lift each pot when I see the topsoil has dried: if the plant container is heavy, it still has water in it. If it is light, it needs water. Invest in a good grow guide with pictures, or download some pictures of healthy cannabis plants AND cannabis plants suffering from various conditions on the Internet. We have a grow guide on our site, too. Best of luck, HB!

Mark & Dan, I have to admit, a few people's posts below bothered me a bit. Although they were trying to be "polite", they were chiding you all about your response time to questions. As a faithful reader of your website, I would like to thank you for your hard work and diligence in keeping up this incredibly informative forum. I, as well as many others, appreciate the work you all do to keep us all informed. Mark, we wish you the best with your Crohn's disease and most of us understand if you need to take time off. Keep up the good fight, and blunts for everyone! - TX4LIFE PS> The internet is a big place. Use some initiative to find the answers to your questions if it is time sensitive.

WEBMASTER:  Thank you sincerely, TX4LIFE! I have been feeling guilty about not answering these questions in a more timely fashion. All I can say is that Crohn's is a difficult condition to manage at times...

this is a response to the light man, go with the light brand called Hortilux very expensive but veryyy bright, provides maximum lumens

WEBMASTER:  Hortilux is an excellent brand, and a bit more pricey. Some growers always use them, others use "standard" hydroponic HPS or MH lights.

Hey Bud (no pun intended) Although I have done this before 15 odd years ago I am NOT up on the latest tech...primarily my question is," which type of weed should I grow?" I will say.. I am a chemo patient(yes I could get Rx but WILL NOT give up my licence since I dont have too for the narcotics or etc)..and I have also smoked for over 30 years so the so-called "daytime weed" is useless to me. Oh I lived in Nepal and India and Thialand for some time (4 years) and really consider myself somewhat of a affectionado.... with that info in mind I am still under-experienced in todays hybrids( except the readily available versions... northern lights?ok but weak... ie strawberry bud-useless etc) I love both great Ind/Sat's yes more preferable to the heavy hash plants...as if you didnt guess...I also am only doing 2/3 plants at a time (totally personal..I do not sell either) in consideration of space and height issues (ie not letting them touch) I am seeking clarification of TYPE as well as lighting..can I really get away with 600w? and what about this NEW coupling of many of the "new energy efficient bulbs"? (the regular light bulbs that look like pigs tails?) which seems to be becoming popular? Thanks for your advice it is greatly appreciated.

WEBMASTER:  Hi Cameron! I'm a Crohn's Disease sufferer myself, so I can provide advice on what strains have worked for me in getting rid of nausea, illness-related stress, and also restores (some) of my appetite. I've found Northern Lights cross-strains (i.e. NLxSkunk, NLxBuddha), if grown well, works excellently for me. You may have been smoking poorly-grown Northern Lights because, honestly, it is a primo strain. Shiskaberry has also worked very, very well for me. So I'd say try one or two of these, the more Indica-oriented strains. About bulbs: there are new types of bulbs being research and (slowly) released to the general public BUT stick with a good high-pressure sodium (or metal halide, or both, depending on your growing technique/number of lights in the room). Those "pigtail" lights are high-intensity flourescent, which can be used to slowly vegging seed sprouts or clones but not good vegetative growth or blooming. I hope your health improves, Cameron! All my best.

Hi Everyone ... I'm willing to hear from anyone on this question as I'm sure there are lots of people who will know the answer. I purchased a great HPS light kit for $199, the only drawback being that it came with a "standard" bulb. I have been growing plants under it and they are doing excellent, however, I would like to get the best bulb possible to optimize my space. In your experience, which HPS bulb yields the best results? Also, if you know an online store that it can be ordered from that would really help also. Thanks!!

WEBMASTER:  I've met growers who use a "standard" HPS bulb like yourselves with excellent results. A more expensive bulb, such as SunMaster, may have the potential to increase your yield slightly... but then again, the most important factor is you, i.e. the growers. All-in-all, I'd say stick with a standard HPS bulb for now (although I'd like to know the brand name, just to be sure).

anybody whos having problems with spider mites, use sm90 available at most hydroponic stores, it comes in a concentrate and you mix it with water, it smells like lemon and sontihng about the citrusness the mites dont like. Spray them for a total of three times but wait three days between each spraying.There eggs hatch every 3 days. Of my 3 years growing i only had spider mites twice and both times this completely removed them. Any questions just direct them to nick and ill post to reply.

WEBMASTER:  I've heard good things about SM90, and your spraying every three days is an excellent suggestion., Nick. This was in veg state, I assume? Have you had mites during bloom, and did you use SM90 or another pesticide? I find that organic pesticides are pretty flexible, and can be used (but not over-used) if there is an infestation of mites.


Comments

maybe a moderated forum might be less work for you Mark. most of the routine questions here are so common that simply scrolling down the page a "few weeks or months" is all it takes to find the answer. most people should try that first if theyre too lazy to actually search your grow guide. a moderated forum would turn the atmosphere into more of a discussion than questions and answers. you could still make sure people behave and share accurate information...

WEBMASTER:  We'll look into a moderated forum, it does have some advantages to it. Thanks, shy guy!

My mothers were growing fine until they got about a foot tall then they just seem to droop. They are still growing ang the leaves are still pretty green but starting to yellow just a bit starting from the bottom of the plant. I'm using general hydro. nutrients. do you know a good mixture for keeping mothers? Also Ive seen twice now on one plant just the center blade of a fan leaf die, what the hell is that all about?

WEBMASTER:  You should follow the directions on the label for feeding, usually its 5 or 10 ml per litre. Sometimes you'll have to add less or add more nutrients to the water, of course. It's hard to tell from your description if the plant needs more nutrients or if the roots aren't taking in enough nutrients. If your fan leaves are dying I suspect under-feeding, although over-feeding is usually the more common mistake. How often have you been feeding the plant, and how much?


Comments

I wanted to personally thank indica-nadian for the mite control post. Thanks so much for sharing, posts like yours are what it's all about. I haven't personally ever had a problem with mites because I keep the temperature in the low 70's. My plants always turn out great and without bugs, however, I am going to buy a feather duster and be ready for the big day. I'm sure my luck won't go on forever. Cool temperatures really do help though, although I know not everyone is able to maintain them. Thanks again indica-nadian! I, and I'm sure many others really appreciate it.

WEBMASTER:  I'm going to try that feather duster advice as well, and I'd be glad to hear about your experience with it.

Although it may seem a little uncalled for, I think "janicegirl" has a point. Although everyone appreciates what you are doing and cannot expect you to do more than you are able, there are some people that need questions answered quickly as they need to take appropriate action. I have a couple of suggestions. The first one is for those asking common questions: Many of those questions are already answered on other areas of this site, and if not, can be easily found elsewhere. I often see questions here that could be answered in seconds if the person just took the time to look it up, as in GOOGLE, YAHOO etc. Very little effort is required - I suggest you do that before posting here and then waiting for a reply. My other suggestion is for Toronto420: Mark, why don't you open a forum that allows others to respond to the questions. You can still answer the difficult or more complicated ones but the more common questions could be answered by others quickly. Just some thoughts ... again, believe me when I tell you everyone really appreciates what you do here, but for some beginners especially, quick answers can be important, and even if they're not, they SEEM important. :-) Keep up the good work!

WEBMASTER:  Thanks for the advice, Suggestion! I shall try to answer questions more quickly.

to the guy with lung cancer ,maybe try edibles or look into vaporizers.

i noticed alot of unanswered questions,i know your busy by why does it take you so long to respond,im not tryna be rude and disrespect intended but peoples plants could be dead by the time they get questions answered,....its a reason a bunch of people write you every day.......cause they dont know what there doing 100%.like i said no disrespect intended just something you might wanna think about.well enjoy your day

WEBMASTER:  I do apologize for the lateness in reply; I suffer from Crohn's Disease and occasionally I have a bad flare-up that stops me from doing anything. Again, my apologies.

Do you think you will have any other feminized seeds sometime. How much cheaper do you sell seeds during the weed march as i want to get alot of skunk 69

WEBMASTER:  We are working on getting some other feminized strains; during the Cannabis March we usually have a $20 for 5 seeds sale, but we can't always offer Skunk 69 at that price during such sales. Thanks for the question, Herbert!

for those with mites, separate your plants so they dont touch, then with a feather duster, roll it from the bottom to top and try to remove webs, still spraying with bang and cold water, use the duster daily and try to keep temp down and humidity around 35-40, this worked for me with lots of wind.

WEBMASTER:  A duster, eh? That's an interesting idea. I will try that, although I suspect it would be best to buy a duster that can be soaked in hot water afterwards to kill off any mites picked up during dusting. Thanks for the great tip, Indica-Nadian!

How would you use Cannabis if you had Lung Cancer? Please give as much information as possible. Thanks and God Bless!

WEBMASTER:  You can cook with cannabis; a popular recipe is "ganja butter", where butter is infused with cannabis and you then use that ganja butter in your cooking. Check out Puff Mama's website, she's an excellent cannabis chef: http://www.puffmama.ca/ .

Is it easy to deliver to Australia? Does our mail system detect your product?

WEBMASTER:  It's not easy to ship to Australia because we've had some packages stomped on sending them there; I suspect Australian Customs think the word "fragile" is the Italian word for "Crush". So we can't guarantee safe delivery to Austalia, sorry.


Comments

is it ok to prune during the flowering stage???

WEBMASTER:  I dislike trimming or pruning the cannabis plant because it is using all of its leaves for the creation of food or as food; leaves that are dying are still a food source for the cannabis plant, up until the point it's completely dead and falling off. Many growers will "top" their plant once to encourage it to bush out to the sides and avoid any other pruning/trimming unless absolutely necessary due to pests, etc.


Comments

After reading your grow guide about using Pro-Mix. One can understand that one doesn't have to check water PH to grow good plants but does it help to check water PH? Will it increase yield, taste or potency if water PH is 6.3(veg)/5.8(bloom) instead of 7.0 straight from the faucet? Is it worth the time and energy to check and balance water PH when using Pro-Mix? You guys are the best for accurate information - Thank You!

WEBMASTER:  Using Pro-Mix I've never had pH problems, so I usually check the water only if I've moved into a new house to determine if the pH is wildly off into a range Pro-Mix can't handle. But that would usually make the water undrinkable, so I've never had a problem. That's always worked for me, best of luck!

Hi guys, thanks for taking the time to answer this. I've read your section on cloning and watched the video but I still have a question, maybe I'm just stupid, I don't know ... anyway, as I understand it, after taking the clone you put it under the 12 hour light cycle until it shows sex ... if it's a female then you put it into the 18 hour veg cycle until you want to put it into bloom for good, and if it's male, throw it out. Is this right? Or should you just put the clones into veg? Thanks a bunch!

WEBMASTER:  Some growers throw out the clone they used to sex if it is female, but others keep it and put it back into vegetative stage, although that usually stresses a plant. On the whole, many growers stick to the original motherplant if its female and don't bother much with the cutting they cloned for sex. And, yes, if it's a male, get it out of the grow room! :)

I was wondering why your "White Widow xxx" is only 10% Sativa and 90% Indica when the true White Widow is mostly Sativa? Also, can you give me more information about this Indian XXX. I can't seem to find any information regarding this unknown strain. Thank You

WEBMASTER:  I'll certainly look into that, that's a good question. I'll contact the original supplier of the seed and, yes, I do need a description for Indian XXX, I'll get the original description for that one as well soon.

Umm I was wondering if yout thought it would be to late to start outdoors in the season ? , Ive already got seeds starting to germinate. Should I plant outdoors, or in ?

WEBMASTER:  August is too late to plant outdoors, in my opinion. I'd be sticking to indoor growing until next spring.


Comments

Ummm , I just bought 5 pack of summertime buddah the other days from you, and was wondering how long before it sprouts, and when its done growing how much will it yeild ?

WEBMASTER:  Seeds can vary a bit in time in sprouting, from 18-24 hours to a few days. And the yield from the plant depends on how large you grow it; many growers if they have the room to grow their plants larger than the "sea of green" method can get one to two pounds per plant, depending on the space they have as well.

how far should you keep plts or pots apart from one another under 1000w

WEBMASTER:  Keep your plants far enough away so they're not touching each others leaves, if at all possible. A cannabis plant will sense it is being "crowded" if its leaves touch another plant (or even a wall) and may begin growing more "up" than "out", leading to stretching plants. So you can keep your plants very close to each other, but if you can avoid them touching, they'll probably bush out to the sides better.

My oh Me oh My so many silly questions, I agree below, thank you so much for answering these Mark.! I am almost finshed flowering my lemon hash plant:)! I gave it water and nutrients today ( the 1st), and I am palnning on leaching it ( with 25% nutes:)) around the 9th, and then leaving it in the darkeness for 3-4 days...I have to, as I am going to Montreal so It will be unatteneded, and in the dark in a closet.! Is this safe do you think?? My Northern Lights is in the middle of her flowering period, Since i am leaving, I have decided to entrust a friend to take care of her. Since it is in flowering hours and my friend does not have a light. Is id OK to put her outside, or should she stay inside, in a window ( It is an indoor plant), And then he can put her in a safe dark place for the 12 hours of darkness. Will this be suitable? Last and not least, I was given a purple sativa that was in early flowering with a broken stem, the stem has been broken at the base for more than a week and she is not very healthy, I took a few clones from the bottom but nothing seems very alive. there are many seeds on it,,,, is there any way i can keep it alive enough for the seeds to develop, or is it hopeless. I have tied the stem , and tried rooting a few clones but it looks hopeless, Any suggestions. Thank you so much. Have a wonderfull Day Mark, :)!!!

WEBMASTER:  Hi Milly, there are no silly questions. The cannabis plant needs a regular, uninterrupted light/dark cycle or it will become stressed and possibly become stunted, go hermaphrodite, die, or a combination thereof. You'll have to invest in a timer to regulate the time, absolutely. A plant with a broken stem will either recover slowly or die quickly, on the whole: so, yes, take some clones from her soon! Best of luck, Milly!

OH - MY - GAWWWWD... I was just reading the latest questions... man I don't know how you guys do it... Now tell me, do you ever get the feeling that someone might have a multiple personality disorder. ::--)) Geeeeez... More power to ya guys, if you can keep this going you are capable of anything. Wow.

WEBMASTER:  Heh, sometimes I wonder if I have multiple personality disorder, but then I tell myself I don't. Thanks, Cannabis!

how much is co2 n how much do u need

WEBMASTER:  co2 is relatively inexpensive, although some initial investment is required to rent/buy a tank to hold the co2, and grow room equipment. You'll certainly need a co2 sensor in your room so you don't pass out from carbon dioxide poisoning in your grow room if the level rises too high! Carbon Dioxide occurs naturally in the air at about 0.03 to 0.04 percent; increasing that amount to 0.12 to 0.15 percent is the optimum co2 "zone" for cannabis plants to produce a higher yield.

Hello Toronto420, great website you have going. Been reading about growing plants in Beds instead of using Pots. For example using a planter box 1.2 meters x 1.2 meters x 30 cm deep filled with Pro-Mix and grow 6 plants under 1000w. Or is it better to use 3 or 5 gallon individual pots filled with Pro-Mix for 6 plants under 1000w. From reading one can get better results using the beds over the pots. Do you have any opinions on this Theory? Thanks for all the great help and support you give everyone!!!!! PS. Toronto420 Strains Are Excellent and better then anything in Amsterdam!!!!!

WEBMASTER:  Thank you for the very kind words, 'Bed! Growing in beds certainly sounds like an interesting idea, thanks for the tip, I'll look into it more!

how big of a room do you need 2 grow 20-25 plants,that atleast contain a lb of bd or more per plant,how much light 2 use ,pot size,trey size,wat size air filter 2 use,how much water should i have in my reservoir,i want high grade top notch quality wit my quanity

WEBMASTER:  Remember its the size of the room, not so much the number of plants you want to grow. You could grow 20 plants in a 5 x 5 space if you bloomed them early, or 20 plants in a 20x20 space if you grew them big. By blooming early you have faster "turn-around" time to begin another cycle, while taking the time to grow the plants larger will increase your yield BUT slow down your turn-around time. So, generally, room-size dictates harvest yield, not the number of plants. There are many different reservoir equipment, tables, etc, so I can't answer how much water you'll need in your particular system. Good luck, aries!


Comments

if im lookin 2 get a lb/plant,how many plants should i grow in a 4x8 closet,what wattage of light and how big should the pots be,thanks 4 ur held

WEBMASTER:  I figure you could fit a nice 400 or even 600 watt light in that closet; you'll probably have to use small-sized pots, 2, 3, or 5 gallon. Good luck, Aries!


Comments

is there anyway ur bothers rite below you can get seeds with out have to com to can,

WEBMASTER:  Sorry, we only ship seeds in Canada. The laws in the US are too restrictive at the moment, and I don't want to be extradited to the US and beaten by cops wielding rubber hoses filled with sand, even though I'm Canadian.

hi its me again,i dnt mean ak-7,i mean ak-47 and i seen a piture of the blueberry but i never actually seen it,,wats da best blueberry seed out there,i want tha bud to smell like berryies(strong smell) taste like berries and look a lil berryish,o how can i save on my electricity

WEBMASTER:  Uh... well, our Blueberry Skunk cannabis seeds are excellent, so that's a great place to start ;) And saving electricity, one good tip is you'll be amazed how much energy you save per month just by turning off room lights you're not using, and not keeping the television on while you're not watching it. I was amazed by how much I saved!

hi you doing mark,i grew up smokin purple haze but now a days nobody has it so i rather grow my own(only 1 plant)my question to you mark is,is there a plant out there thats like purple haze(purole in color of bd) but wit a higher thc,i luv to get f'ed up where im dumb fouded and cant move...hey what can i say thats jus me,is there a better seed out there even if its not purpl

WEBMASTER:  Purple Haze is a great strain but there are many other non-purple-in-color strains out there too ;) I'm a big fan of Northern Light cross-strains because that is one powerful strain, no wonder it's famous!


Comments

hi you doing,im andy,and my question is when should clone from sprouted seeds and how many clones should i snip

WEBMASTER:  If you're cloning for sex, you'll want to take a cutting as soon as possible; a rule of thumb for taking clones is wait until the plant is at least 24 inches tall and two months old (although I've taken clones a little earlier than two months if the plant is growing well). Remember if you're cloning for sex you need to take at least two clones, in case one dies.


Comments

i cant decide on a time to feed the plants,have the fans on(rotating and filter fan...i forgot the name but its like a squirrel fan...you know what i mean,a time to have my co2 on.can you tell me a good time to set em all to my timer so they work all together in both veg. and flowering room.also how do i keep my rooms at i goo temp. when it hot outside and when it cold out side thank you.......o yea im using my closet

WEBMASTER:  Check out our grow guide on our website, it's got a whole lot of info on fans, etc. I know when to feed/water my plants by the "eyeball/lift" method: I check the plant's leaves to see if they need food/nutrition in the water (or if they're getting too much, or not enough of one particular nutrient) by eyeballing the plants, and I lift the container holding the plant; if it is light in weight, I know it's not holding much water so it's time to pour it on.

hi you doin,i read some tips on your websitse about gettin 1.5 to 2lbs out of one plant.im thinkin of growing 2 diff. types of seeds 1.blueberry and 2. ak-7,are those goods to use,im looking for a fruity but very potent seed so if you kno of any i would appreciate it,but6 my real question is how much space do i need to grow like 5-10plants.what size pots do i need in diameter,what size light(probably 1000watts) how many hp light fixtures would i need and wat size closet would i need,any tip on how how to get roughly 1.5 to 2lbs out of closet plant would be appreciated........thanks fot taking the time to respond

WEBMASTER:  Both of those strains are excellent, JJ. You could grow 5-10 plants in a good-sized closet if you're growing them very small via the sea of green method, or a small-sized room, let's say 6x6 or so, if you're growing them a little larger. The pots you use will again depend on the number of plants you have in the space, 5 or 10 gallon-sized. And, yes, a good 1000 watt grow light will work perfectly. One 1000 watt light needs minimum about a 5 x 5 space, and you'll need room to move around the grow space, of course. Best of luck, JJ

wats tha best seed to grow if you want a friuty taste n smellssomething colorful (not just green) and you want a real strong high with a anice size yield

WEBMASTER:  Our Juicy Fruit x Northern Lights x Skunk is a great strain with a fruity taste, as is Blueberry Skunk. Check out our seedbank and thank you for the question, Terence!

Hey Mark, My name is Alex and I was wondering because i'm not 18 or over, and I don't have a license Would It be possible for me to purchase some seeds. I was just looking to grow a plant for myself, but I do not want to associate with dealers to get seeds.

WEBMASTER:  Hi Alex; for legal reasons we prefer to sell to those with adult ID, because the government could change the laws about seed sales anytime. Sorry!


Comments

how many branches should I trim off the bottom of my plants,and when should I cut off there head.

WEBMASTER:  Generally I don't trim branches from the bottom of the plant since the plant is using them for food. You can "top" your plants in the vegetative stage, I usually top mine when they're at least 2 1/2 - 3 feet.


Comments

Hi again. Mark I have started 6th week of flower and I am loaded with mites. they are starting to web on the tops a bit, so I pick off the web. I bought spider mite predators about 3 weeks ago but they don't seem to be controlling the mites very well. Is there anything I can use at this late stage of the game for these bastard mites. Please advise asap as I am nearing the end and I don't want the mites to ruin a beautiful crop. Thanks Alot "bud". Have a great day or two.

WEBMASTER:  I hate those (*$#@ mites too; Ontario seems particularly bad for them. At this late stage, the only thing you can really do is spray with ice-cold water or one or two BANG all-natural pesticide; anymore BANG spraying at 6+ weeks may change the taste and final smoke. Sorry again for the lateness in reply!


Comments

Hi Mark I was wondering if I should switch from 3 - 1000 sunmaster warm deluxe to maybe 3 - 1000 hps. I have been growing for a number of years, at first I used 2 - 1000 hps to 1 - 1000 halide, then I switched to 3 - 1ooo warm deluxe by sunmaster. I was wondering if I should switch to get better budding. Thanks your help is appreciated.

WEBMASTER:  I myself use standard grow-rated HPS bulbs, or sometimes a combination of HPS and MH. But some growers like the warm deluxe sunmaster; the important thing to remember to use is: use what you like and what has proven itself to work for you. Which combination of bulbs gave you your best harvest? Many growers mix HPS with MH and that works just as well as Sunmaster, but again, you are the grower, use what works, and don't worry about if you could have gotten a tiny bit more bud from the harvest - EVERY grower wonders about that ;)


Comments

I forgot to mention I'm indoor ebb and flow, with the weevil problems

WEBMASTER:  You'll most probably have to clean everything, because those damn bugs like to hide!


Comments

One week into flower and I've got fucking WEEVILS eating my fan leaves!! Mark HELP !!

WEBMASTER:  Sorry about the lateness in reply, I hope your weevil problems have been solved. If not, spray them with ice-cold water, or BANG all-natural pesticide.


Comments

do i need a license for the seeds and do you sell to people under 18?

WEBMASTER:  You don't need a license to own seeds; since the Federal government could change the laws about selling seeds anytime, and sometimes do, we only sell seeds to adults.


Comments

Hi: I hope this email greets everyone in happy and healthy spirits. I am having a hell of a time with the summer heat. Plants are stressed buds are fluffy. I have Co2 enriched air and still having problems. Is there any strain that anyone knows that can take the heat a bit better?

WEBMASTER:  Thank you, Dean. I've had to take a week off due to health (I have Crohn's Disease), but otherwise doing okay. I know what you mean about the heat, it's been a bad summer for that. Usually the more indica-oriented strains do better in the heat, as many sativa-dominant strains seem to more prone to stretching. Try maybe a Blueberry Skunk or Northern Light cross, and hopefully next summer will be less hot!

I THINKING ABOUT GOING TO CANADA IN OCTOBER. I JUST WANTED TO KNOW WHERE THE COFFEE SHOPS IS LOCATED

Thanks for the tip and yes there are brown/tiger stripped. I pulled out all of the pale/white ones. I will try the toilet paper. And I use rockwool cubes once the seeds pop, same as the G13Xcross and white widow.

WEBMASTER:  Hope everything goes well, James!


Comments

Hi all, I'm planning on hanging a 600hps verticallay inside a column of chicken wire and grow the plants on the outised (v-scrog style), my question is, how far from the bulb should the plant "tops" be? I'm currently using a 250hps and i think i've got loads of extra space and I want to upgrade past the 430's right to the 600's. The screen is a bout 20 inches (or more)in diameter, and I have space on the floor for about 5-6 pots. Can I fit a 600 in?

WEBMASTER:  If you have loads of room, you should have no problem fitting in a 600W. The lamp should be about a foot and a half away from the tops of the plants, two feet max. Sounds like an interesting setup you're building, Harry!

I wanted to reply to james60504 - hope you guys don't mind. This may or may not be a possibility but I have found that some paper towels (and I'm sure it's the same with napkins) do not work as well as others. I believe it's because of the bleaching process used in manufacturing. The cheapest paper towels or toilet paper (even better) seem to work best. Having said that, I would love to try some of your seeds if you'd be so kind. Besides finding out how they fair with another person, I'm always looking for seeds anyway so it would help us both out. I can pay you if you want but I am not a rich person. :-) I would suggest mailing them with no return address but we can discuss that later. If you're interested, email me at this address: hushwingAThushmail.com Substitute the '@' sign for 'AT' of course. Good luck to you! Mark and Dan: Sorry for the intrusion but not many people seem to know about 'bad' paper towel.

WEBMASTER:  Hi Hushwing! We have no problem at all with opinions being voiced by anybody in our public forum, since it's a public forum! Thanks for the tip about the bleach, and I agree with you, the cheapest toilet paper works excellently. I'll send you an email, you can also email us at sublime@toronto420.com .

I have some seeds from a G-13 buddha I crossed with white widow its been 2+ months since harvest and I havent been able to get the seeds to germinate. The seeds pop ,and the tip pokes out but than all growth stops?? I use white napkins and di water pH to 5.7. all of this is sandwhiched between two plates on a heating pad. I have tried twice with the same results. Could the seeds still be two young?

WEBMASTER:  How did you transplant them? Into a Pro-Mix growing medium in a cup/small pot? A ph value of 5.7 is pretty good, although some may say that's a bit on the acidic side. Don't use white napkins to sprout them in, since napkins have a tough weave in them and you may be damaging some seeds when removing them; 1-ply toilet paper is good. Also check the seeds - are they a nice medium brown with black "tiger" stripes?


Comments

Do you need a license to buy seed form here?

WEBMASTER:  Cannabis seeds, since they have no THC or other complex/simple cannabinoids, are legal to sell in Canada without a license.


Comments

hey mark i have a question. i have read up on Sea of Green growing and it seems like a cool concept to me. all the sources I have read from say that it is for hydroponic/indoor gardening only, but would it work outside aswell? my idea was to start plants in small pots and let them get natural sunlight during the day, and then leave them inside under very very dim lighting; just enough so that the plant stays in vegetative growth. then later (early september? or when they are 10" tall w/ no branches yet) i would move them outside permanently, and the switch of light cycle would trigger flowering. just wondering as it is getting late in the season and I would like to still get a crop this year. the strain I was considering was an indica, possibly blueberry skunk or skunk 69. thanks very much, peace

WEBMASTER:  I would avoid doing Sea of Green outdoors, although some growers would disagree with me. You're going for a fast turn-around time, and indoors you have total control over the Sea of Green method. If you move them outdoors, and there is a week of cloudy weather, you will lost turn-around time since the plant will take longer to flower and/or require a longer flowering period. However, many growers start their plants indoors and then move them outdoors if they're not using the Sea of Green method. Moving them outdoors in September is also way too late; I'd move your vegged plants outdoors NOW and hopefully there will be enough time for them to veg, especially if they're Indica strains.


Comments

what is the fastest growing marijuana plant or species from seed to smoke avalible not just through you guys but in general. thank you have a good day

WEBMASTER:  A general rule of thumb is most Indica-dominant cannabis strains will bloom faster than Sativa-dominant strains. Indica strains can have a flowering cycle of 7 to 8 weeks, while some Sativas can take 14 weeks or more! That's why many growers prefer growing Indica-heavy strains.


Comments

Afriend need to know the wattage needed for 2x2 ft grow area for personal use he's a cannabis medical patient live in an apardment will be his 1st grow. for Hps and MH bulbs. smokes 1 to 2 joints aday Dics injury

WEBMASTER:  2x2 is a pretty small space, a bit too small for a 400W which is the minimum power I'd use to grow (250W or lower, in my opinion, are underpowered for good harvests). If your friend can expand the space just a little, to 3x3, a 400W will be just fine.


Comments

i got a space 4 feet wide x 3 feet long = 12 square feet. and i got a 430W. 34W to 36W per 1 square foot. tell me if this is a good coverage. and i dont know how many plants i can harvest in that space im thinking 6 cloned females. is that to many plants to end the harvest with or too little.

WEBMASTER:  That's about the right space for a 400W. Check out the chart at http://www.happygirl.ca/lessons/space.htm and you'll see you're right in the zone!

After posting I found out I have thrips. Only a few, and not very many any more. There is still lots of spots, and poop ( that was the black stuff) . What should I do if i dont want to invest in a sprayer ( i am very broke) I have a fan blowing on the plant, and I have killed just about all of the bugs. I dont want to spray it with anything that would effect the taste, what do you think about spraying with ice water just out of a normal spray bottle. When it comes time to harvestare there any steps i can take to make sure i dont smoke any bugs?

WEBMASTER:  Unfortunately a hand sprayer, the inexpensive small kind, just doesn't have the force to drive off bugs. Pump sprayers aren't that expensive - check your Canadian Tire or other hardware store. You only need a 5L pump sprayer. And about not smoking bugs, it won't kill you, but the only way to avoid smoking bugs is to get rid of them in the first place, unfortunately. Best of luck, milly!

hey man whats up hope all is well was wondering if i have a 2 stage room veg and bud i will be cloning my mother continuassly with ur skunk 69 can i keep the clones under the 1000 watt or do i have to put them under a diff light what i want to do is get a continous cycle going

WEBMASTER:  Many growers use the 2-stage growing method as it ensures regularly harvests year-long. Keep your clones on the periphery of the light, not right underneath it. When they start showing roots, transplant them into a pot with Pro-Mix but keep them on the periphery of the light for a couple of days so they can develop some roots. When the plant has 2 sets of strong, healthy leaves, you can move it closer underneath the light. Good luck, jay!

i have 2 females growing under a 400W MH. First of all, i didnt pre treat for pests, and put them into flowering. a week ago i found little tinyy, green crawly critters, maby 20-30 over the week, i have killed them all and looked under a microscope but not been able to find what they are in gardening books. They are little, yellowish green, very small, no wings, little black dots on their back. they have not eaten anything, instead the damage is like little bright green dots and spolothes and, black dots. do you know what the bugs are, and what the dots are. I dont see very many bugs anymore, but many black dots that are tiny. under a microscope they do not moove. they are scaring me, i am pretty far into flowering.. any suggestions.????? also , what are the best flouresents i can buy to grow actual buds under, i need to get rid of my light, its old and the room gets to up 35, no good. so how many flouresents, and what kind do i need for 4-10 plants? thank you mark! you are wonderfull for devoting so much love and time into what you do.

WEBMASTER:  There's no damage? Odd. Sounds like spider mites to me. In bloom stage, try using ice-cold water to get rid of them, or there is a product called BANG which is a natural insecticide which can be used in bloom (sparingly). Check out our info on bugs at : http://www.happygirl.ca/pump_sprayer.htm . Hope you have a great harvest, Milly!

Hi Mark I have equipment to hand my 1000 watt light in the horizontal or vertical position which do you recommend?

WEBMASTER:  Most lights these days can be mounted in either direction; however, if you are mounting a light vertically it is best to check with the manufacturer if such is recommended. I've always hung my lights horizontally, as it is much easier to adjust the height of the lamp in relation to the plants as they grow. Good luck, Turd Ferguson. Heh, that's a funny name. S'funny.

i have a marijuana plant from bagseed its approxamitly 24 days old and is a foot tall. its has 6 branching sections and is beggining to grow its 9 leaves well its second set of 9 leaves. my question is at what stage does it begin to smell potent like marijuana? and my second question would be is a 5 gallon bucket sufficient enough for it to grow it seems fine for its age but idk so im asking you.

WEBMASTER:  Many strains in the veg stage will give off a slight odor, usually heavily influenced by chlorophyll. When the plant begins to bloom, that's when the cannabis odor really begins, as the resin is very strong in smell! If your plant is still in veg stage, transplant it to a pot that is at least 8 to 12 inches wide. We have a good graphic showing the size of pots you should use, in relation to plant size, at http://www.happygirl.ca/lessons/stage1.htm . Good luck EJ!

hi guys i was just wondering my sisters has crohns disease an we were wondering how hard it would be for her to get a legal medi card for pot

WEBMASTER:  Hi, Dan420 here. I am sincerely sorry to hear about your sister having Crohn's Disease. I suffer badly from the same malady, and it affects my life a great deal. I am a legal exemptee smoker/grower myself. The application process for me was quite painless, fortunately: the people at Health Canada in the medical marijuana division were very nice and polite. I waited about three months, but I finally got my card. My advice for your sister would be to find an understanding gastroenterologist doctor to sign the forms; it can be difficult to find a doctor, but not impossible. You can also bring a legal waiver for the doctor to sign releasing him of all legal ramifications of prescribing medical marijuana to you; that waiver makes a lot of doctors more open to signing your application. Check out our info at http://www.toronto420.com/how_to_obtain_legal_cannabis_in_canada.html . Send my regards to your sister!

i want to start by saying this is amazing and i pretty much love you guys so ok if your going to try to grow alot of plants in a basement what watage of light would you need to get the best yeild abunch of 250 -400 or a bunch of 1000 wattage bulbs and do flouresecnt lights help along with other lights

WEBMASTER:  That would depend on how big your basement is, and how much of the space you want to use for growing. Generally up to 4x4 foot space is good for a 400 watt, 5x5 a 600 watt, and 6 feet by 6 feet a 1000 watt. Check out the info on this in our grow guide at: http://www.happygirl.ca/lessons/space.htm .

Hey man I know you get tons of orders all the time (its understandable, toronto420 rocks) but I did the freakin stupidest thing earlier so I need your help! i sent in an order for 5 blueberry skunk and 5 white widow x buddha but i FORGOT TO PUT MY RETURN ADDRESS ON THE ENVELOPE. most of my address was written on the money order but I didnt put Ontario, Canada. so if you find any money orders with no instructions on where to send the order, then please email me at anyone-for-tennis@hotmail.com (with dashes not underscores) and I will give you the full address. Ive bought from you before and I was really satisfied with everything so rock on boys.

WEBMASTER:  We've been monitoring the mail but it hasn't shown up yet, Dizzle. Sometimes the post office will send back mail with no return address; we'll let you know when and if the order arrives!

If growing Blueberry/Skunk and G13/Budda in the same bloom room, when would be the best time to harvest all plants 56 days or 63 days (or somewhere in between). Understanding that one strain is an 8 week and the other strain is a 9 week but is there a happy medium? Toronto420 is always a great help. Thank You

WEBMASTER:  While the Indica plants usually do finish in 8 weeks, and the sativa plants 9 - 10 (or more), the best gauge is monitoring the plant. Harvest it when the plant starts to begin drooping (i.e. dying) and it appears resin production has ceased. Hope you have a great harvest, Harvest!

I have the same problem as the last post, german ate not and also use one of those small heating mat greenhouses.. The humidity is so high in the greenhouse water droplets form on the clear plastic top. Could this be part of the trouble? I thought high humidity was good fro germination, is this right? My containers are covered so if the water droplets drip it shouldn't matter. I'm afraid if I take off the top it won't be warm enough for the seeds to germinate. Another thing I wondered about is, my place is air-conditioned to 72 degrees so I though that might screw them up too. Any tips for better germ rates? It costs me a fortune to get just one plant cause I lose so many to non germination. Help me please!

WEBMASTER:  A high humidity is good for germination, but try occasionally (once or twice a day) removing the plastic top for a few minutes for the young plants to "breath" a little bit (i.e. you're releasing trapped oxygen the plant has respirated).

I always have trouble getting a good percentage of seeds to germinate. I am using one of those miniature greenhouses with a good quality heating mat. I attempt to germinate seeds using both the 'paper towel' and 'shot glass' methods. Out of the last 15 seeds I have tried to germinate, only 3 have popped. Those 3 are now growing fine; however, 3 out of 15 is just not acceptable with the price of seeds. I have tried planting the ones that didn't pop without success. I have tried leaving them for up to a week with no success. I have propped the lid of the greenhouse open to see if that would help - nope. The 3 seeds that popped all did so with the shot glass method. Do you have any suggesstions? I feel like I am doing everything right but it's just not working out. I am very frustrated! If you had to choose, would a cooler temperature be preferable or a hotter one? I am asking because the only thing I can think of (other than poor seeds) is the temp in the greenhouse. It is capable of reaching 90 degrees so I generally try to keep it a little below that (80 - 85) but maybe it's still too hot? I have also tried the 90 degrees and actually that is when the 3 seeds popped in the shot glass. Sorry for the long post but I am going crazy with this! Is it me or the seeds? Be blunt. :~) All suggestions welcomed happily. :-)

WEBMASTER:   I've always used the toilet paper method (don't use paper towel, the weave of it is too tough to remove from any sprouts growing into it), and its always worked for me. Sorry to hear about your seeds! If you bought them from us, return the label and any unsprouted seeds & we'll be glad to replace them, we want happy customers!

Mark, I have some Pro Blend Bloom for hydro 2.5-2-5 their soil fert is 1.5-4-5. Could one use the hydro ferts in soil? Would you need to supplement the hydro ferts. Use the right stuff? Can average joe purchase nutrients from you?

WEBMASTER:  I always advice using Pro Blend Pro BX, or any other similar growing mixture that has NO food added to it; I just find it's easier to know exactly how much you're feeding your plants. You could use the stuff you have now, but watch out for over-feeding in the young plants, you'll probably have to cut back a bit on what it says on the food label to feed young plants.

Im just wondering if its too late to start plants outside , I live in mississauga.Is there any seeds that finish quickly. Also could you dry outdoors in a shady area in a tent where there is a breeze.

WEBMASTER:  In my opinion it's too late to plant outdoors now; maybe we will have a summer that will last until September, but I'd be too worried about conditions during the bloom stage to plant outdoors. Indica-heavy strains do finish earlier. I never dry outdoors, myself: too much of a chance of airborn molds & fungi, plus insect etc, attacking the drying bud.


Comments

hey Mark, its getting kinda late in the summer and i was just wondering if it was too late to plant seeds outdoors.

WEBMASTER:  I would say its too late now to plant outdoors, unfortunately. But there's always next year!

Hi again Mr. Mark I was wondering what the best nutrients "you suggest" are for growing hydroponicaly in flower cycle only. Tanx for your help.

WEBMASTER:  Dan420 here, don't call Mark "mister" or it might go to his head ;) I could go on and on about nutrients, but I think our section on plant food will answer your question best: http://www.happygirl.ca/NPK.htm . Thanks for the question, George, best of luck!

Hi Mark I was wondering if I have Licence to produce and licence to possess. do you still give some free seeds to card holder, and is it possible to get clones. Thanks for your help.

WEBMASTER:  We do send free seeds to Canadian federal exemptee holders, within reason of course :) We don't do clones, but many compassion clubs in Canada can direct you to finding clones.

I am currently venting into another room in our basement. I would like to vent outside. Is their risk of being detected by heat seeking cameras. I prefer to grow in the evenings. 10Pm-10Am as it is easier to control the heat. I would be venting out the roof.....5" pipe. I have 1000w light, carbon charc. filter can, and 450 cfm fan.I will continue to draw fresh air from another roonm in the house.Does heat only show on the cameras in the dark??

WEBMASTER:  If you have only one light the chance of detection is very low. Since it is in the basement it probably won't, or can't, be picked up by heat-imagine technology. The venting warm air will be, but with only one light it will be quite small. Unless the cops are targeting you for another reason and start watching you specifically, I think you'll be okay.


Comments

In Southern Ontario, outdoors, what do you feel is the latest you can plant fully rooted clones outdoors????? I realize alot will depend on the strain of course, but in general???

WEBMASTER:  Indeed, it depends on the strain but there are other factors. Many growers in Southern Ontario get their plants out in early spring, some will wait a few weeks to gauge how the season is shaping up to be - cool or hot. But generally you want to get your plants outside in the warm spring as soon as possible to take advantage of all those growing days! :)


Comments

this is for dave in the post below....Pro Mix BX in large bails is readily available in southern ontario at many greenhouses and also at hydroponics stores. Greenhouses tend to be much cheaper and more discreet. Ive NEVER had an issue finding it this time of year. Give up on the hardware type stores and stick with greenhouses and Im sure you'll find it. a few minutes with a phone book is all it takes...its worth the trouble to look for it. your "soil" isnt something you should be compromising on...

WEBMASTER:  Thanks, SG! True, many greenhouses will have Pro-Mix but they'll be off "the beaten path", i.e. not downtown but still worth the drive to!


Comments

Sorry to post again but I really should have mentioned that the 3 inch seedling I am talking about is only 2 days old. Now (12 hours later) it is more like 4 inches and the second set of leaves are slightly bigger. I'm thinkin' I might have a 2 foot stem before the first set of leaves develop. LOL Just kidding, but this really is a strange seedling (I think) so now I'm wondering if monster plants start this way or rejects. :~) The stem is very strong by the way so that is not a concern yet. The strain is 'Haze.' Keep up the good work guys! You're awesome!

WEBMASTER:  Give the plants a few more days of growth; you can't really gauge them at this stage. I've seen some young plants grow a bit odd at times while "establishing" themselves, and then they develop normally.


Comments

Hi Guys ... I have a question and a tip for Dave - hopefully. First, is it normal for a 'pure' Sativa strain to stretch as a seedling? I have one seedling that is now 3 inches tall yet the second set of leaves are just barely visible. It is growing like crazy but nothing seems to be happening in leaf development yet. I have another of the same strain that is about 2 1/2 inches and the second set of leaves is about half the size of the embryonic leaves - which seems much more normal to me, although possibly still stretched. FOR DAVE: I was in the same position as you, not being able to find the recommended Pro-Mix 'variety.' I ended up purchasing 'Premier Pro-Mix for Seeding and Potting' at Canadian Tire (white bag) and it is working great so far. Hope that helps.

WEBMASTER:  Sativa-dominant strains do tend to grow taller than indica-dominant strains, so indeed are prone to stretching. Move the lamp closer if you can; you may have to "top" the plant to encourage side growth. Thank you for the suggestion about the growing medium, Gardner! Any info is always appreciated :)

Hi, I have a terrible case of spidermites. how can I kill them including the eggs? t.y, Willy

WEBMASTER:  Read our section on spider mites at http://www.happygirl.ca/pump_sprayer.htm . I sympathize with you, Willy, I hate the little buggers with an anger that would best be called "indescribable".


Comments

im in the phillipins,tropical weather,the day light here is 12h light and 12h night year round ,this.how does weed grow here,and what kind a seeds can i get that will adapt to this climat and lighting

WEBMASTER: Hmm... you'll probably be best vegging the plants indoors for 18 - 24 hours of light under a good plant-rated flourescent or low-powered metal halide, and then moving them outdoor. Probably the Hawaiian strain would do well for you, or try some 100 % Indica strains, many of them are quite "hardy".


Comments

I am trying to hunt Premier Pro-Mix BX or HP down, but it seems every Rona around me carry's Promix Perrenials (35L, white bag), Promix Vegetable and Flower Bed Mix with mycorhiza (35L, white bag), and a Promix For Potting bail which isnt black or white, but some sort of brown fancy colour :). Of these three Premier Pro-Mix'es which should I buy? I'm just confused that the names (like BX, HP, BRK, GSX) aren't on these bags of Pro-Mix ... Thanks in advance :).

WEBMASTER:  The kind of growing medium you're looking for has NO pre-added nutrients to it. There's also a brand called Sunshine Mix, maybe the store has that. If you can find a store with a manager that is actually approachable, maybe they can find the product for you... if the store has various Pro-Mix products in it, they can certainly get Pro-Mix BX for you.

Mark, I am going to be moving across the country. I have been storing the seeds in the crisper as you suggested. My question is if they are going to be okay during the three day car ride. I could keep them in a cooler with ice if they need to stay chilled, but it would be easier to just keep them in the car. Any suggestions? By the way, thank you for all the great advice you provide all of us on your forum.

WEBMASTER:  Keep them in a cool, dry, dark spot. I wouldn't put them in a cooler with ice because they might freeze, and that'll kill the seeds. If your car is air-conditioned, keep it reasonably cool. If not, as long as the car doesn't get too hot everything should be okay.


Comments

hey guys. i've got some plants outdoors in 4 gallon pots, they're about two and a half feet tall. it's still a few months until harvest time, should I cut them back, or does this only apply to growing indoors? and if so how much can I trim them without losing any of my yield? thanks.

WEBMASTER:  Don't top the plants if visibility isn't an issue; if you can let the plants grow tall, let them! Remember that the center top of the plant will form the main cola bud of the plant if left on; growers cut that off to encourage plants to grow more to the sides than up, something you may need to think about if you want to keep your plants short. When topping, don't cut off the side branches is one of the biggest things to remember. Let me re-print an answer Mark X gave to a similar question awhile ago:

Topping the plant means to remove its primary growing shoot. The plant then redirects its energy to the next two closest shoots which become primary shoots. This may be done as many times as the grower desires. Note, however, that the resulting buds will be smaller than if the plant had been left untopped. The real issue becomes "Does the mass of the two new buds exceed the mass of the otherwise untopped cola?" The answer to this question varies from strain to strain, perhaps even, from plant to plant. When topped, frequently the two central growth tips will stop growing for a period, while the plant directs its energies to repairing the damage central shoot. A collateral effect of topping is that the plant bushes out, that is, all of the lower branches continue to grow when the growth of the central shoots pauses. This can be useful in a propagation technique like SCroG, in which it is desirable for all of the bud sites to be on an even plane. The slowdown in growth may be avoided by pinching, rather than cutting, the growth tip. This does not cause the resulting bushiness in the lower growth, but does cause the two secondary tips to become primary. How, when and where to top are also matters of ongoing debate. Ultimately, it becomes a personal decision of the grower, based upon his own experiences and goals.. however if you are further in the flowering stage.... you may experience Dormant buds at each node (auxiliary buds) are kept dormant by the level of auxins traveling down the stem from the shoot tip (apical dominance). The farther away a node is the less auxin it experiences, and at some certain level the bud begins to grow. We remove the growing tip to induce the formation of lateral branches by removing the source of auxin, which is mainly produced in young expanding leaves. If enough young EXPANDING leaves are left on the plant when the tip is cut out, apical dominance will not be broken until the leaves stop expanding and auxin levels drop. So, don't skimp when you pinch and cut back to mature leaves. ***Auxins are a class of plant growth substance (often called phytohormones or plant hormones). Auxins play an essential role in coordination of many growth and behavioral processes in the plant life cycle*** ***Dormant-in a state of minimal metabolic activity with cessation of growth, either as a reaction to adverse conditions or as part of an organism's normal annual rhythm.***

Also, don't top the plants if they're in bloom stage.

hey buds how are yas, just wondering how long it takes for delivery of seed thx god bless

Great site and super fast shipping! Thanks a bunch Toronto420.com I got all my seeds and I can't wait to get them in the ground!

Hey freind hows it going great i hope. What can u tell me about a bloom box buy bc northern lights it looks real good but does it work as well your advise is greatly apprecated STAY HIGH BRO

WEBMASTER:  Hey B. It's going great, thanks! To be honest, I've always been a little bit skeptical of bloom boxes. Sure, they may look really nice and high-tech, and for some people they work great. That's fine. But I think the method I use - growing in pro-mix in pots under a light - is more cost-effective, easier, and yields a bigger harvest. But that's just my opinion :)


Comments

Hi Mark. I have three juicy fruit and three BC God Bud under 600 Hps.I'm going on holiday's for two weeks.I really do not want to harvest early.If I raise the light about two and a half feet above the canopy and over water would they last two weeks.I plan on harvesting when I get home.Smooth smoke is very important to me. I'm concerned that if they partially dry under the light the smoke will be harsh.All the best,Twisted.P.S.They are in five gallon buckets with Pro Mix.

WEBMASTER:  I wouldn't do that, over-watering can promote root rot & fungal infections. It can be risky, but you may need to ask a very, very, VERY trusted friend to do the watering while you're away. Remember that other things could happen to your plants if left unattended for even more than a few days - insect infestation, the lamp burning out or tripping the fuse, etc, etc.

high mark ty for the info on the 420 G13.....and manyyy ty to the dude who put up the plans for the home made carbon filter... everyone should invest in one for UNDER $30 AWESOME results. took me 20mins and backyard {where its vented to} went from stinking of ona gel and mmmmmmmmm to NO SMELL AT ALL...even removed the ona from vent, can build to size depending on your needs and fan size[ I went to a 650cmf in a 5X6 room, with air cooled hood and vent both connected to 1 fan, thought it was over kill at first, butt setup now runs great] mine is 5" round X 14" long...so simple>>>>heres the link once again http://www.marijuanapassion.com/forum/showthread.php?t=8184 a quick question about the genetics.....planted several of the "crossed" BB/g13.....week 6/7 of bloom and the aroma form them is very different, some a strong bb scent, the others a bb/ hashy scent...is it possible that the bb OR the G13 is the more dominiat from seed to seed or would it vary that drastically??? either way it will great smoke, butt saved some the g13 pollen from the last batch of males, and i like to experiment lmao! cya soon

WEBMASTER:  Sometimes I notice that too, the same strain of plant will vary a little bit in smell. I wait until final drying to gauge the odor, to be honest. You're right, experimenting with cannabis genetics is quite fascinating, and can yield you award-winning seeds!


Comments

hi Mark thru your experience do you happen to know if having a television on in the same room as the plants at dark time has any effect on the plants?? Thx!

WEBMASTER:  Good Lord. Yes. ANY light will have an effect on plants, especially if they're in bloom stage! In the dark cycle, keep the room totally dark. And don't subject your plants to television - I've heard on good authority that "American Idol" is fatal to cannabis plants.


Comments

i was wondering if someone was to have alot of plants (50-100) how could they go about getting rid of the smell without spending alot of money

WEBMASTER:  I assume you're growing indoors. With that many plants, there's no way around it: you're gonna have to shell out some cash for a big carbon filter, inline fan, and odds & ends. If you grow the plants using the "sea of green" method, the odor may be a little less but still, all someone needs to do is sniff a little bit of fresh cannabis and they can report you. Take my advice: invest in a good air filter, rated for the size of room you have. Paying a bit of money is better than paying a lot of time in jail!


Comments

greetings Mark; well I just chopped the skunk 69 plants after only 6.5 weeks of bloom(had too). Regardless,,they are so puffy and sticky and (I dried and smoked some) potent! Thx for the cross. is your nothern lights stronger??if so how much??can i return the 2 of 5 - skunk 69 seeds that did'nt germinate?? ..........Thx for being there!!!

WEBMASTER:  Glad to hear the harvest was potent! All of our seeds are very strong; northern lights may be a little stronger than skunk 69 since the skunk is feminized, but remember a big part of the buzz you get is how good you grow the marijuana!


Comments

Can the police see 10 marijuana plants or less that are growing outside using thermal imaging or infrared from the air?

WEBMASTER:  In some areas, police regularly perform helicopter patrols using various detection technologies. The most common for cities is thermal-imagining heat detection of grow lamps through house's roofs. Most often these patrols are done at night because the heat detection is easier, so many growers have their light cycle on during the day (although if you're in veg cycle, you'll still have some light being produced during the night). If you're a casual grower with one or two lamps, your chances of being detected are less than someone with half-a-dozen or more lamps. I know there is some type of insulation out there, it looks like aluminum foil, that helps stop thermal detection, but I cannot for the life of me remember the name of it. I'll do some research.

O and by the way I am 6 and a half weeks into bloom with WWxB,NLxB,BBS,and ur very own skunk 69.I just wanted to say without u guys i would be no where near where i am now i GREATLY appreciate all ur hard work and dedication to this site TYVM

Hi Mark,I have 22 plants 2'-3'high,stretching, sides are restricted with bamboo, all plants have 3-4 shoots and have all the bottom branches chopped off. It is a nice even canopy. 1000w hps,good vent. 17 days into bloom. Pro-mix, 1 gallon containers, wwxxx. My question is, the pots look small compared to the size of the plants,would you transplant them into bigger pots 17 days into bloom? will this be of advantage to me? The plants look great now and already have well developed buds....small, but they have potential.If you suggested I transplant I will, what size pots would you use? I wanted to have them only 14" tall but they stretched in the heat wave we had 10 days ago....sheeesh. If it helps..... quality is waaaayyyy more important to me than quantity. Thanks BUD.

WEBMASTER:  Yes, you can and should transplant them immediately into 2 gallon containers. It has been a hot summer so far, so stretching this year is a common problem; sounds like you've got a good handle on what you're doing! Good luck Rick!

I'm cloning/mothering with 40 watts (t-12 flouorescent tubes)and then bloom with a 250 hps. Would it be too much to upgrade the hps to 600? Too much of a shock to the plants from 40 watts to 600? Thanks

WEBMASTER:  As long as the clones have established roots, they *want* more light. In fact, I'd never use a 250 hps myself. You can upgrade to a 600W, just make sure the light is far enough away from the tops of the plants, it will have to be farther away than the 250hps, probably a good foot and a half more. It won't be a shock to move the young plants to the 600W as long as you initially put them on the perimeter of the light, not right underneath it. Monitor the plants to see if they respond well; if they do, move them more gradually under the light and remember to transplant into bigger pots when they're outgrowing their container.

Hey Everyone - If you haven't signed the Marc Emery petition (Block Extradition to the U.S.) you can do it here: http://www.petitiononline.com/Emery/petition-sign.html I've managed to get over 20 signatures for this petition and I'm old and sick, so, you can do it too. :~) Support for people like Marc Emery is imperative, not to mention Mark X and Dan 420 who are obviously dedicated to the cause and have helped us medical users more than they will ever know. Us common folk need to show our appreciation for those working on our behalf in any way possible. I've been meaning to throw up a link to the petition for a while now, so thank you 'happy guy' for giving me the reminder. Mark and Dan: The Stairway to Heaven starts with Toronto420 seeds - thank you!

mark i just wanted to let everyone who has doubts about your site and the work you do i recieved my 15 seeds in the mail as promised out of that 13 spourted i accedently killed one so that left me with 12 out of that 3 were males . so iam very pleased iam so pleased that my sex life with the wife has never been better so she thanks you to. you r the man. everything is looking good next time iam in toronto i look forward in to coming to the store . but for now i have only 2 questions . how long into the bud cycle can i spray with soap and water i only have a small gnat problem in dirt and i beleave it is under control . i have no mites but iam 3 weeks into the bud cycle and i just want to be safe. also what is going on with mark emmery i know his trial has started but have heard nothing. i would also like to remind everyone to get out and support him. after all if it wasent for people like him r you we would not be able to enjoy some of the finner things in life . which in my eyes should be r god given right. thanks for all your help and keep up the good work because not many have the balls to stand up for ther rights r the right s of others

WEBMASTER: Er... that's the first time we here at Toronto420 have been praised for improving someone's sex life! Huh. Please send my regards to your satisfied wife. About your questions: personally I'd stop around three weeks in bloom with the soap and water and try ice-cold water. Get a sprayer, the big pump type, and fill it with ice cubes and water and let chill; spray plants with that & the freezing cold should take care of many damn'd mites/gnats/etc. If that isn't working, you may want to try BANG! once or twice, it's a natural insecticide you can use in bloom (although I advise sparingly). But, yeah, as the plants bloom and more resin is produced, you have to be more careful with the insecticides... and then there's just a point where you have to give up and harvest what you can save. I hope you get a great yield, happy guy!

We have a card to produce our own plants from the government. I have heard that you can have a certain number of plants in veg and some in bloom. The government counts the plants in bloom as your plants you can have for your card. I also have a mother plant now, is that ok? Please let me know Thanks

WEBMASTER:  Even the government isn't sure of its own rules, to be honest. Probably the best way to protect yourself is to stick to the plant limit you've been given. If you have extra plants in veg you could conceivably argue to the judge your need for backup plants in veg, but your success would of course depend on if the judge is compassionate towards people like us with chronic pain. I'd advise sticking to the number of plants you've been rated, but of course I'm saying that to cover my own butt ;)

Hi Mark: I have some of your Skunk X NL seed that I have grown into mothers and cloned. How would you grow them in a 4x4 ebb and flow table under 1000 watt light? SCROG, Sea of Green? Basically what I'm asking is - how many plants would you put in the table given the breed and lighting conditions? THanks

WEBMASTER:  A standard rule of thumb for ebb & flow with Sea of Green method is four plants per square foot. I don't use the ebb & flow system myself, I prefer growing in Pro-Mix. And for how I'd grow it, I'd stick with your basic table or tray and reservoir plus the usual trimmings. Here's a handy site with some good info on ebb & flow: http://www.hydroponics.net/learn/build_ebb_flow.asp Best of luck Turd! Heh, that's a funny name. Turd Ferguson. S'funny.

Hey, my friend recently put some plants outside for the season and i was telling him about the N P K levels of nuetrience for his plants and what they should be getting. ive been looking over a few different pages and it seems to vary from page to page and vary greatly when its hydro vs out door. i was just wondering what you might feed your oudoors plants in terms of nuetrience

WEBMASTER:  Many outdoor growers use Miracle Grow 20/20/20, you've probably seen it in blue "chunky" powder form. If used properly, it's great for outdoor plants because some nutrients will be drawn out by the surrounding soil or by sunlight/evaporation BUT there's enough left for the plants to use. Don't over-use it, though, it's strong stuff! You can find it at many gardening stores or even places like Canadian Tire or Home Depot.


Comments

Hey Mark.. For my 1000w hps ballast, should i buy a generic $40 bulb... or is it worth investing in the hortilux with extra blue... is there is significant difference in terms of yeild... Its just that the hortilux is about $100... thanks man

WEBMASTER:  I've found as long as the bulb is rated to grow plants and is from a reputable company, that's the best way to go. I'm a little wary of generic bulbs, to be honest. I usually spend around $100 for a decent 1000W bulb. Sunmaster has a 1000W Super HPS bulb for around $99!

I am 4 weeks into flowering and I overfed like a week ago. This is my first grow and I thought I had the feeding going well. The tips were burnt, so I cut the next watering down to only using half of nutrients (5ml/gal of Pure Blend Pro Bloom instead of 10ml). All of the leaves then got burnt around the outsides of the leaves on each tip. I flushed the medium as soon as I seen it was getting worse and just yesterday used plain water for the watering cycle. My plant still looks like it will survive but each day more fan leaves are turning yellow on me. Is there anything else I could do? How do I resume feeding and in what dosages? I am using 600W and the plant is an indica just over two feet tall.

WEBMASTER: Sounds like both over-feeding and under-feeding issues are going on here. In this case, give the plants one feeding of VEG nutrients at full strength. If they recover, go back to full Bloom feeding until you decide to start flushing for harvest. If they don't recover, start flushing for harvest. Sorry I didn't respond sooner, I've been swamped with work! Best of luck Max!

Is there anywhere on your site you can direct me to that can give me a good recipe to make hash or bubblehash with my clippings. In fact what is the difference between hash and bubblehash?

WEBMASTER:  Here's a great site for you to check out that has an excellent explanation of hash & how to make it in a variety of ways: http://cannabisculture.com/articles/2312.html . The differences between hash "types" is the process in which it was made, i.e. how the trichomes are removed from the cannabis plant matter. As you know, many growers use the excess plant matter from their cannabis harvest after trimming; there are different techniques to remove the trichomes from this "skuff", some techniques are better at filtering out plant matter from the trichomes being removed for hash.


Comments

I have been reading about some test grows where the lights are raised higher during the last few weeks of bloom to act like the sun is changing angles during the fall season. Does this method really help in making harder buds with more resin or is it a wives tale? Thanks you for your time.

WEBMASTER:  Y'know, I heard about that too. I always think a plant will do better the closer you get to optimal outside weather conditions. Two growers I've spoken to say the angling method does help, but a couple other of my growing buddies say it's all B.S. I personally think the "jury is still out" on this matter and a lot more testing needs to be done. I suppose from a plant's point of view the nourishing lightsource / sun does move, but then again, I've seen so many people have incredible results using the traditional "stationary" grow light. I think I'm going to do some experimenting with this technique myself, that's often the best way to see if something actually works! Great & thought-provoking questions ML, thank you.

Hi Mark I have 25 wwxxx...clones under a 1000hps in 1 gallon pails. They have grown fast and have stretched,I cut all the side branches of in veg. now they are 1.5 too 2 feet tall. I am in 8 days of bloom.It is crowded yet the canopy looks good and even. I can move 6 or 8 outside, At this time of year will the plants I move still continue to bloom. The 25 plants are now taking up an area of 5 feet x 5 feet.What would you do?? Thanks Man, you have ALWAYS been a great help.

WEBMASTER:  I certainly would not move any blooming plants outside at this point, you'll stress them too much and lose a good amount of harvest. Keep them under the 1000 watt light; I know things may be crowded, but 25 very small plants in a 5x5 room sounds about right if you're doing the Sea of Green method. Keep the ladies indoors!


Comments

Mark ... Why don't you try and find a knowledgable person to help you answer some of the more common questions here? I've noticed that often the answers to questions can be found in other areas of your site (or elsewhere) and/or should be common sense but I guess people just find it easier to ask than go look for themselves. (No offense anyone, but sometimes ...) Maybe not an idea you would like, don't know, but I just thought it might take some of the load off. I don't know how you do it.

WEBMASTER:  Hi, Dan420 here. Mark has been my "cannabis mentor" for some years now. I'm doing more work on this site as part of his nefarious plans for total conquest of the earth via marijuana education. Why that involves me getting him coffee all the time, I'll never know.

hey mark... i just planted my clones and noticed a few days later that there is a buildup of white bubbly liquid where the leaves branch out from the stalk. also in these bubbles, there seems to be little white jucie bugs. also there are mites at the base of the plant which are whit in colour... bnut very tine... thanks alot later

WEBMASTER:  Yup, that sounds like aphids at the leaf branchings. If the outbreak is small enough, you can pick off the aphids with your fingers; you can use a magnifier scope or lens to look closely if you need to. But if the outbreak is more than one plant, spray them with the standards: ice-cold water with a tiny bit of regular dish-soap or Neem oil.

How long should I flush my plants using small rockwool cubes in pots watering them by hand? I've been flushing for a week now just pouring cups of water daily then today I put them in the bathtub one at a time and used a hose to water them, they still had a lot of nutrients in the rockwool but now its all clear water draining from the bottom. My question is now that the water is clear how long will it take the clean water to get to the buds and flush the nutrients out. They have been flowering for 8 weeks today. What happens if I wait too long to cut them down. How will I know how long is too long? I dont want to be smokin nutrients but i also dont want to wait too long.

WEBMASTER:  Flush with water + 25% nutrient solution for better results; I know it sounds odd, but it works. If the plants have another week until harvest, you should be okay. Check out the article I advised Troy to read at http://www.happygirl.ca/lessons/harvest.htm . Good luck bill!

Sorry 1 more ? in regards to flushing i was wondering if u can explain FLUSHING in depth please.TYVM

WEBMASTER:  Flushing is the process of leaching out nutrients from the growing medium so the plant uptakes less nutrients and uses stored food. Makes for nice, clean smoke :)

Hey Mark I was down to ur store and i got 5 KUSH and only 2 germinated and only 1 actually came above ground Im little dissapointed in those results, as i am statrting a new veg period while my others are @ 40 Days bloom evthing seems to be ok,Also i was wondering when i should start flushing as i am approaching 6 weeks in bloom and was wondering if 2 weeks of flush would be a bit much but im not sure as i am looking for QUALITY nice burnning and tasting smoke.TYVM N TC

WEBMASTER:  If you can mail me the cardboard backing of the seed card I'll be glad to replace ones that didn't germinate. Most growers flush about 1 or 2 weeks before harvest, so you're about right. Flush with water + 25% nutrient solution for better results than plain water. Check out our article at http://www.happygirl.ca/lessons/harvest.htm . Good luck Troy!

i just planted a clone at my cottage . i will not be up here every day to water it . i have just put in nutrients and water. it gets LOTS of light too. i may be gone for as many as 4 days at a time... will this be ok? ...hopfully it rains.

WEBMASTER:  I assume it's planted in ground and not in a pot outside? If so, it depends on the soil conditions in your area and current weather. Personally I'd be worried about leaving a young clone alone for four days; once the plant has grown a bit and established itself in the new soil then you can worry a teensy bit less. So, four days I'd say is a risky gamble to leave a young clone outside. Good luck though, marker!

hey Mark. i am curious about pests. i have a few month and a half old plants outdoors, and yesterday noticed small whitish/yellow bugs on the undersides of some of the leaves. this morning i noticed that there were small shiny black and brown bugs on the undersides of some of the other leaves. any idea who these guys are, what kind of damage they might do, and how I can get rid of them? I have some pictures if you want more info. thanks.

WEBMASTER:  Hmm... sounds like a mite and possibly an aphid infestation too. Check out the Toronto420 article about this subject at http://www.happygirl.ca/pump_sprayer.htm . Good luck Bob Dylan, love your music.

Mark, hope you are having a great summer! I would like to produce some new seeds without pollinating the entire crop. Is there a safe way to pollinate one bud without affecting the others?

WEBMASTER:  You will need to *totally* separate the female plant you wish to fertilize with pollen. Many growers use a "pollen brush" in which they collect pollen in a little jar and then brush onto the female plant. Pollinate the female plant as far away from the female plants you wish to keep unpollinated; some growers won't even pollinate plants in the same house they have unfertilized plants in! Change your clothes and shower yourself after pollinating to avoid bringing in pollen to your grow room by accident. Good luck TX4LIFE!

Mark ... I had written about germination problems and you said to send back the package ... well I have looked and looked and looked some more and cannot find it. I thought I saved it (with the cards inside) but - can't find it. I am wondering if I could get my address to you somehow and you recogonized it maybe that would work? I am at a loss here ... what do you think? Thank you so much.

WEBMASTER:  I got your email and will gladly send you replacement seeds, DS. Sorry for the delay in response, we've been having Internet problems here. The technician replaced our Internet feed cable from outside, so hopefully things will be better!

i hav two questions, first of all when do plants start flowering outdoors and second of all if i set mother plants out now (mid june) how big wud they get and what wud i expect to yeild

WEBMASTER:  The onset of bloom/flowering cycles in cannabis plants varies a bit with their particular strain, but a good rule of thumb is about eight weeks. Some plants will bloom earlier, some later. I've seen plants bloom a little after six weeks, and some that needed fourteen weeks! Mid-June is a bit late to plant unless you have some good early bloomers like a heavy Indica strain. Cannabis plants can grow over ten feet in the proper conditions. Yield-wise depends on how good a grower you are ;) I've seen many growers get over a pound easy from each plant.

Mark, I have a 3 seedlings that are 3 weeks old. I have a 20 inch fan on low and 6 T40 4 foot lights (6500K daylight for 3 and 1900K indoor grow light that is on the red side for the other 3. One of the seedlings has stopped growing and the others have grown up about 1 inch higher then the one that has slowed down. The leafs on the one that is slow growing are a dark green and the stock is dark purple, any ideas? I also used jiffy pots that break down, I left them on the plants when I replated them in a bigger pot because they break down. Now one of the larger seedlings is now showing signs of the purple stock Also is sun light good for seedlings or is it too strong? One more question. I have been using FloraNova Grow for the veg. I have been feeding every other watering (about every 5 days between waterings). The question I had is do I follow the .625 ml/L for seedlings or should I do 50% of that or 25% of that?

WEBMASTER:  Your plants sound like they need stronger light than flourescents now to grow properly. You'd best get a stronger type of light, like an hps, for better results. From the purpling it sounds like nutrient lockout; your plants aren't getting enough light energy to convert the nutrients to food. Check to see if any of the leaves are growing in mis-shapen. I've never had problems with Jiffy pots, although I find planting sprouted seeds in Pro-Mix works fine. Try giving your plants just water next feeding, then give them a half-strength feeding and see how they do. And invest in a good 400W, 600W, or 1000W growlight, you'll get much better results. Good luck Eur!

how often should i water my newly planted clone?

how often should i water my newly planted clone?

WEBMASTER:  Water it when the growing medium is more dry than wet, but not totally bone-dry & certainly before the plant begins drooping. Don't keep the growing medium wet all the time, you want the roots to seek out water to keep them active and healthy. So water, let dry until the plant container feels light when lifted but before plant begins drooping, and you'll be good.

hey bud, sorry to bother u once again, just wondering how or what to do if i have to harvest with mites, can i soak the bud in ice cold water or will this damage the trichomes in any way, i read somewhere that u can use no pest strips and there not harmful to plants because they dont touch the plant, but are toxic to humans as well as mites, so cant use where u frequent often...thx for your time see u soon. god bless

WEBMASTER:  No, don't soak the bud, you'll damage the trichomes and possibly promote a fungal/mold infection as you dry them again. With a mite problem at late bloom stage, it's best just to spray with ice-cold water a couple of times (don't soak the plants, though, but spray them good to knock the little buggers off). Some growers use a product called BANG, which is a natural insecticide you can use in bloom; some growers love it, others don't because they say it affects the final taste of the bud. All in all, it's best to harvest what you got if the mites aren't going away, give the grow room a good disinfecting scrubbing, and start again. That's the life of a grower: some harvests are great, some not so great. Oh, I don't like pest strips personally; even though many say they're non-toxic, I invariably get part of my body sticking to it when I'm moving lights. Some of the cheaper pest strips do give off fumes, I know that from just smelling the things. Best to stay paranoid about mites and spray as soon as you see any white tiny spots on your plants.

I was wondering how many seeds you can get if you leave the males, and how far the pollen can travel. Also what is the best way to dry outdoors if there is one.

WEBMASTER:  A fertilized female cannabis plant can produce hundreds if not thousands of viable seeds, depending on the plant's final size. Pollen can travel hundreds of miles through the air; some plant pollens of different species travel thousands of miles sometimes through the windy skies! Pollen also lands on animal and people, objects etc, and can fertilize plants if brought to nearby female plants, so be careful if you come in contact with a male cannabis plant before visiting someone's grow room... ! Also, DON'T dry your harvest outdoors; you have much less control over the best drying conditions & you'll be exposing your drying to plants to airborne molds, fungi, and dishonest hippies passing by. Good luck HERBert ;)

Hi Mark, I recently put up 1000w hps light in a 4 x 4 grow room. I am having a heat issue. the room is at 31 I bought a 150 cfm industrial fan. How should it be positioned. I can not vent out of the house in this room. Can I use duct material to blow the air out of the room? Or cold air in? Any help would be greatly appreciated.

WEBMASTER:  To be honest with you, 1000w is a bit powerful for such a small grow room; we usually suggest 5x5 or 6x6. Have you thought about using a 600W light? You'll get great results in the 4x4 space and your heating issues will decrease. You can use duct hose to bring in cool air or move warm air out of the room; many growers mount their carbon filter on the ceiling of the grow room. As long as the air hose bringing in cool air allows that air to circulate around the room before being expelled by the carbon filter & fan, you're good. So you could put a fan outside the room with a hose going into the room (for cool air intake), and the carbon filter & outtake duct hose at the ceiling of the room. But that's a lot of work in a small space; I personally would go with a 600w light and avoid much of the headache. Good luck Mary!

He Mark.. I need to know the maximum amount of electricity that can be used in an apartment... I 'm not worried about raising suspision as each apartment does not have individual meters... my concern is popping the fuse thats in the hallway on each floor... i know that inside each apartment there is a fuse box ... but also there is one (or two from what i've been told) main fuse(s) for each apartment unit... my question is pretty much: Do i calculate my electricty usage based on amps or watts (in terms of load on the fuses in for the entire unit) and what is a safe watt or amp usage so i dont pop the fuse outside. My only concern is blowing the fuse and not raising suspision... For example: is 60 amps too much load for an apartment? and if the ballasts are running on a 240v does that decrease the load on the apartment?. Your the man... Thanks.

WEBMASTER:  Hmmm... that's quite the question! Dealing with electrical issues can be the most major headache for the indoor grower, as I'm sure you appreciate by now! It's best to start off by figuring out how many seperate electrical circuits you have going throughout your apartment. Depending on the size, it can be two, four, six, or more... usually the bigger the apartment, the more separate 120v 15amp circuits you get to play with. You'll have to flip breaker switches to figure out which circuit is which. I don't know the size of your apartment.

 60 amps is a sizeable load, you should look into a getting a "power board" (a fuse box & electrical plug board to consolidate and or convert your electricity); 240v can run lights more efficiently with less load IF it is done properly, but one needs good basic electrical knowledge to set up. I could go on and on about electricity in hydroponics, it's a huge topic in and of itself! Check out my online article at: http://www.happygirl.ca/lessons/power.htm . The other thing I can tell you is that it's very good to be friends with a competent electrician! Good luck, go slow, and don't touch any bare wires (I speak from experience).

once im done my cycle, and i start leeching.. i add the final flush.. the next day i check my rez and im at 800 on the dip stick.. do i need to change the res daily until the dip says 0 after a flood?

WEBMASTER:  Check out this link:  http://www.cannabisculture.com/articles/1738.html . I usually answer questions myself, but this link is a great quick & thorough read on reservoir systems both active and passive. I prefer the Pro-Mix method but hey, every grower discovers what works for him or her! My best wishes to a great harvest to you, J!

Hi Mark. I wrote about doing some outdoor growing about four months ago .I wanted very short outdoor plants to mix between my flowers.I bloomed them indoors under 600hps for two weeks when five inches tall,like you suggested. I have two juicy fruit and two BC God Bud mixed among some poppies about two feet tall blooming beautifully.Hope all is well. Twisted.

WEBMASTER:  Sounds like you have quite the garden growing there! Mixing the best of indoor and outdoor growing can yield incredible results to creative growers like yourself. All our best, Twisted!

i am a first time grower i just planted my first clone, im groweing in a great spot with lots of sunlight and am hoping to yeild 1 pound per plant, do u think this is possible and what type of special care should i use??

WEBMASTER:  While it's not so much the yield you get from the number of plants you have as it is the amount of room you grow the plants in, 1 pound isn't out of the ballpark range although I don't know how big you are growing your plant. If it grows out to be big & bushy, five feet tall or more, than you're probably not far off at all... some growers do even better!


Comments

Hey Mark... humidity during the day is obviously a problem causing stretching and lower yeilds... however how about high humidity during the dark hours... is it harmful? if you can touch on high temperature during the dark hours and the impacts as well... thanks brother.

WEBMASTER:  High humidity (over 65 - 70% abouts) is always a problem, day or night. Humidity affects the plants ability and "willingness" to draw water (and therefore, nutrients) from their growing medium. It's okay if humidity dips a bit during the dark stages - cannabis plants naturally expect that - but it should'nt go up by much, that could very well confuse or damage the plant. High temperatures and high humidity will damage the plant anytime, unfortunately, the longer it goes on for during the growing cycles, night or day.

10 seeds 4 females 6 males not very good odds man, just thought id inform you 2 Nl X Skunk, an 2 Whitewiddow X Buddah, but im not complain healthiest plants ive ever seen dude, i was just hopin for male females tho, may next yr

WEBMASTER:  I grant you, the female/male ratio from seeds can be a bit of "the luck of the draw" but overall our customers are pleased with the number of female plants they get. Besides, having four very health cannabis plants is much, much better than having ten sick ones! ;) You should look into cloning, many growers will have a mother-plant and take clones off it to bloom, saves lots of time!


Comments

Hi I was wondering The yield and potency of Summertime Buddha and Fast pine seeds.I was also wondering how potent the smoke is and yield if you leave the males with the females

WEBMASTER:  All of our seeds come from parents of excellent genetic heritage, it's up to the grower to coax the seed's potential into a great plant! And... uh... leave the males with the females? You NEVER want male plants with your female plants, in the bloom stage they'll fertilize the female plants which will lower your harvest by about, oh, up to 90%. When it comes to growing cannabis, be like a radical feminist who's just been given an Uzi 9mm automatic pistol and a hunting permit for men to go with it, i.e. KILL THE MALES.

hey bud, how are u, just letting u know that u are correct and i only have to fill out form "c" health canada called me back and confirmed that , but the first time i asked them they told me that i had to go through a whole new process, so i would say that if people have questions ....ask mark first ,he does know. thx bro god bless.

WEBMASTER:  Well, we do our best here at Toronto420. The kind people at Health Canada have been very nice to me everytime I've spoken with them on the phone; they're very understanding of the chronic pain many people like myself and you experience everyday from health conditions. Glad to have helped and all our best!

is there anything u can do beside throw out your carbon filter once it stops working?

WEBMASTER:  Many carbon filters can be re-filled with carbon particulates; check with the manufacturer of your carbon filter, they should be able to do it for you at a reasonable price.

Hey Mark im thinking about adding a 600w to my existing 800w for next cycle.I was wondering if my 247 cfm fan hooked up to a carbon filter will keep my room cool or should i upgrade ventilation a bit.also should a total of 1400w be fairly unnoticable for me as i am in a 2 bedroom highrise complex.O 1 more ? my clone mother room/veg room is a lower temp around 23-25 should this be OK and is 220w enuff for that room as i am planning to veg in there aswell.I am 31 days into bloom is it normal for hairs to change color this quick.TYVM N TC bro

WEBMASTER:  Since your room is already on the low side (23 - 25 C), adding a single 600W shouldn't drive your room temperatures of out the best range, 25 - 30 C. Even if you have to upgrade ventilation an additional 1400W on your montly electricity meter won't tip off anyone; one person uses about 1000W a month, so getting another light or strong inline fan & filter equals "a roommate" if you're ever asked about power consumption ;) 23 C is a bit low for clone rooms, 25 is good. Yes, on some cannabis strains the hairs will change color quite early!

I asked a question a while ago about feminized seeds. I had a plant go herm on me and when I planted the seeds from it they all came out female. You had said these would be feminized seeds but it was "cheating". I have read that these seeds would also be hermy. Could you please explain feminized seeds........ thanks so much. Your the best

WEBMASTER:  Basically "feminized" seeds are seeds from a female plant that has been fertilized by a hermaphroditic plant, or from a hermaphroditic plant like yours. Some growers think using feminized seeds is "cheating", some growers love feminized seeds. Use what works for you. And thank you, I know I'm the best, now if only my wife would believe that too...

Hello I was wondering if you have chronic seeds in stock

WEBMASTER:  Check out the Toronto420 seed catalogue, we update it often!


Comments

is a L of water every day enough for one out door plant ( to 10 Hours of direct sun light )

WEBMASTER:  That sounds a bit low to me. Even a plant in a small container can soak up two liters of water before fluid begins seeping out the bottom. Don't go by an exact number of water litres your plants needs, that can be misleading. You'll have to visually watch your plant for signs of under- or over-watering. Generally though cannabis plants love water and soak up lots of it; if a plant dies from "over-watering" more than likely too much food was put into the water. Give the plant lots of water and the proper amount of nutrients is the goal. Cannabis grows well in a moist growing medium but not a water-logged growing medium.


Comments

How many weeks into bloom can some one use Neem Oil for protection from Mites? Thanks for all your great knowledge!!!!!

WEBMASTER:  Generally the second or third week, although some growers will say you can keep using it to the very end and some other growers will say not to use it in bloom because it affects the taste of the bud! If I use neem in veg stage I use it liberally, but if I have to use it in bloom I ease off on the strength of it because if you do keep using it regularly during bloom it will affect the taste of the smoke negatively. If you have pests in bloom try ice-cold water first (fill a 5l garden sprayer with ice cubes and some water, let chill, then spray) first to try avoiding leaving an "oily" taste. So in veg stage use the neem like a hammer, in bloom use it like a scalpel: veg, spray all the plants, in bloom, spray only affected areas.

Mark, I was wondering if you could provide some air circulation guidance. I have a 1000W MH cool tube light. I live in a condo that has a normal four walled closet (5x5). I have cut a hole in the ceiling, and the air duct runs into the attic to expel the light's hot air. The problem is that the attic is 100+ degrees in the summer, so I am not sure where I should place the intake air duct. Will the air temperature inside the closet qualify, or should I cut into the air conditioning duct? Many thanks.

WEBMASTER:  Heat retention in closets, attics and upper floors is a problem for many growers. If the air temperature in the closet is between 25 - 30 Celsius you're generally good. With a closet like yours I agree that the bigger problem is getting good ventilation into your closet rather than blowing the hot air out; as long as the lamp's outtake hose leading from the closet to the attic is generally air-tight, it won't matter too much how hot the attic itself is when you blow the hot air from the cooling tube/closet (although it may raise the overall temperature of the building, especially during the summer, and if your condo neighbours start having a big problem with their apartment temperatures that could be a problem for you). About the air intake: you will probably have to do some experimenting; I prefer cooling the grow space down first rather than running cool air through a lamp cooling tube. But that's just me. Many closet growers with a ceiling out-take ventilation hole will cut a small intake hole into the closet door near the bottom or side and run an air-intake hose attached to an in-line fan (as long as the cool air coming in goes into the room first and not immediately the air out-take hole/tube, you're good to go). In-line fans are great for cooling closets and are relatively cheap as I'm sure you know. I know having a lamp cooling tube and an inline fan for drawing in air to the closet itself seems like overkill but that's what many growers must do if their grow space gets too hot. In fact, it's a great setup for keeping the air moving & at right temperatures. Bring in cool air with the in-line fan and blow it out into the hot attic via the light tube and that might actually cool the attic just due to increased air circulation up there. Good luck!

hey bud, how are ya, friend of mine been having trouble with mites, she"s been using bang, cold water,dishsoap, individually and combined trying to kill those little bastards, now plants are dry looks like burning of the pistels because they look like their ready to be pulled with the amount of color change, but only going on 5th week of bloom(hashplants)and not much resin build up on the little leaves. Fan leaves look terrible wondering if she can cut them off or deal with the problem till thr end, pistels are brown lower than main cola. thx god bless the little babies.

WEBMASTER: I agree, mites are little bastards and I hate them with a hate unknown to mankind. Unfortunately these plants, being in the fifth week of bloom, will be very hard or next to impossible to recover to the point of having a healthy yield. Keep doing damage control and harvest the plants soon if it looks like they aren't recovering from treatment. Stick to ice-cold water until you harvest now because since you'll be harvesting soon you don't want to make the bud you get unsmokable by heavy application of soap or Bang (yeah, I know they say Bang doesn't leave a tast, but if you use it too much (or anything, to think of it) it will affect the taste of the bud). Get a good quality 5-liter plant sprayer and fill it with ice cubs and cold water and let it chill; spray the plants and the ice-cold water will kill or slow down any mites. After harvesting the plants, if you're going to grow in the room again, clean the room REAL GOOD. Use a strong water/bleach solution and wash the room, floor, and ceiling, there will be mites. After cleaning like this sometimes I spray around with Lysol anti-bacterial aerosol; if you do that, wear an air mask, that stuff is strong and harsh! Wipe off your growing equipment too before using it to get rid of mites. About fan leaves: cannabis plants use leaves as food right to the point where they're dead and falling off, so don't pick off them off for now. Hope you get a decent harvest despite those damn mites!

hi Mark growing skunk 69 in promix should the medium be kept moist all the time?? i got brown spots on the leaves that make me think i am giving them too much water. this is the 4th week of bloom. the buds look great though. also a lot of the fan leaves are yellowing way quick and falling off. Thx 4 ur help bro........

WEBMASTER:  Hi boon, sorry for the delay in response! The Pro-Mix the plants are growing in should be allowed to dry to the point where the pot feels quite light when lifted by both hands but DON'T let the plants get so dry they start to droop. The "lift test" is a great indicator, also look for the Pro-Mix "pulling away" slightly from the edges of the pot as they dry (run your finger along these rim cracks to get rid of them before watering, or else the water will just run down the sides and not soak into the Pro-Mix growing medium). You don't want to keep the Pro-Mix moist and wet all the time as that may lead to root-rot and possibly fungal infections; letting the medium get relatively dry (but not TOO dry) between waterings is a great way to promote root growth because the roots continually search for water, i.e. they don't get lazy. Follow the feeding directions on the label of the food you're using and shoot for your plants being a nice even medium-dark green, i.e. give them extra-food if they're yellow and ease off the food if they're too green or "burning" is the general rule. Best of luck, boon!

this question isnt about growing so hope you can help me still ok so when using the cold water extraction method to make hash and you use the trim from your plants do you use all trim or just the trim with the trichomes on them and is that what hash is just the trichomes or all the thc from the plant. thank you alot for your time

WEBMASTER:  ..I use all trim because trichomes stick to anything so even the leafs far away from the bud have some trichomes on them..... trichomes are those tiny tiny little crystals on the buds and the leafs, that's all that hash is ..... and in fact when done right its a honey-like clear liquid... it actually contains primarily CDC and not THC... put simply it contains more sativa-like compounds (CDC) .. the bud itself contains mostly indica-like compounds (THC)....

Hi Mark ... I've emailed you a couple of times about some germination issues I had but haven't heard from you. I know you're very busy and probably get a ton of email but with all the health problems I have this is very important to me, so, here I am again. :~) I thought it best not to put the info here ... do you know the emails I am talking about? They are from DS in Pet ... Thank you Mark.

WEBMASTER:  ..sorry but I am not answering from my laptop (I'm in a hotel) so I haven't red emails in a while.... ask the questions here please.... with bad germination even if its your fault I simply replace the seeds... mail me the package they came with and you will get new seeds... the warranty is universal...

when growing out doors. would it make a difference if the hole is about a foot deep instead of two feet deep. their about two feet apart from each other. would this depth stretch the plant. and how well does (juicy fruit* skunk* northern lights) grow out doors. and what time should i prune them, i put them in the ground June 3 we got lots of rain these past two days but no sun yet. the temp has been 14 to 20 degrees is this ok. i hope i yield around a pound off each female please help me accomplish my goal. they will receive 9 to 10 hours of direct sun light.

WEBMASTER:  ....it is turning out to be a wet and uneven summer (so far)... hot, wet but cloudy... two feet apart may not be enough if you want your plants to get one pound each.... at this point they should get over crowded by mid July and the bottom half of the plant will not produce as much because of the lack of light.... in any case I would expect (at best) 1/2 a pound per plant from this arrangement .... both varieties do well outdoors but the juicy fruit should yield better due to its sativa genes... skunk yields better indoors..... with the spacing you chose you restrict the plants to a certain size thus whether its 1 foot deep or two feet deep does not matter... if they were spaced out every 4 feet then a bigger hole would allow them better buffer against the "cold" soil and thus yield more.... they way you did it a bigger whole would not increase yield....

hey bud me again ,thx for the info ,just wondering if i have to send a new photo as well, because according to Health Canada i have to reapply and have medical papers done again as well because the renewal is different. before i had auth. to poss. but now i want both....confused i am don't know which way to go thx again . god bless

WEBMASTER:  ..apparently the photograph is good for three years thus as long as they have your picture from the last time you applied they do not need the new photographs.... but to be honest when I re-apply every year I still send them new pictures, because I do not want them to complaint... you should call them periodically to see if everything is ok with your application since it takes 6 to 8 weeks....

WEBMASTER:  ....they problem is not growing it... its a "weed" so it will grow for sure.. problem may be when it comes to the bloom period.... from early July to late September the plants naturally go through bloom i.e. days get shorter and nights get longer (darkness is VERY important to a good bloom)... but if you turn ON all your ambient daily lights when night (balcony lights, street lights, etc.) comes this may disrupt their bloom cycle.... some people simply put a garbage bag over the plant at the end of the day to make sure she stays in darkness..... even if you just let her be naturally you will get some smoke... but the darker she is at night the more of it you will get.....

Hey mark... Consider a 1000w light HPS with a sativa dominant strain... they were topped and pruned while veging for 2 weeks and approx. 1-2 feet in height when set to bloom.. they are about 5 feet tall now in week 5... the environmental conditions are normal ie. humidity and temp.. there are approx 14 plants under the light.. i am using DNF a + b and DNF bloom fortifier... The plants have thick buds growing on them however some have thicker buds than others... actually some have very weak buds at the tips of the cola... i don't understand why... is it stretching?... a problem with feeding?... all my leaves look green and the plant looks healthy... i cant understand why some of my tips are giving such thin buds... please help.. thanks bro

WEBMASTER:  ..I am assuming they were from clones and not from seeds because the explanation would differ... I would say that there is too many plants OR they were vegged for too long..... even pruned I would go down to 10 plants and two weeks of veg or 14 plants 1 (1.5) week of veg, in the second week of veg these plants can add an inch a day in diameter so timing is crucial, couple of days of extra veg time can add feet in the very end, I would usually take out some plant is it happened to me and it does.... it better to cut some plants then dealing with all of them being over crowded.... stretching happens because you have stress like over crowding... they feel over crowded when they touch each other .... when many leafs touch many others from the plants next to it they try to reach out for the light... in many ways its a lack of light problem... with more space and more lights they would get enough light to every branch.... at 5 feet in height only the top 1 foot of the plant is really getting any decent light so that means that the bottom 4 feet is useless plant matter.... they should have really reached 4 feet so that means that the 5th foot was added from stretching....

Hey Mark, I have 25 wwxxx 6"-9"clones under 1000w HPS, 1 gallon pails. Plants are supported with bamboo, minimal stretching. Personal set-up. How tall would you grow these ladies before bloom? Would you consider transplanting into bigger pots if the need arose.....Quality is much more important for me, than yield......wwxxx....now that is heavy Indica...Thanks dude.

WEBMASTER:  ..in 1 Gallon containers with 25 plants  I would veg them to 10 inches high at most before blooming... also I would probably cut off the excess bottom branches as the plants will still grow for the first 2 weeks of bloom and they space may be a bit tight.... with this set up I would try to grow so called "donkey dicks"... i.e. plants that have one main cola but not much of side branches.... if you repot into (lets say) 3 Gallon pots, I would only keep 15 plants and cut the tops off... instead of the side branches... making plants bush out ..... I would veg until 1.5 feet before blooming..... different methods.... since taking the tops off would take longer in veg for plants to recover as well as they have to veg longer to achieve 1.5 feet (but with less plants) it would yield slightly more (in theory).... if its your first time go with the first method...

so other than the trichomes changing from clearish to amberish what other signs are there to tell if the plants are finished??

WEBMASTER:  ..counting weeks.. at week 7 of bloom I would start looking at the ratio of dark hairs to white hairs... when I see that over 75% of hairs turned colour I guesstimate that its time to harvest... it should be within week 8 of bloom.... I may snip a bud at week 7 to taste it, again at week 8.... it is not unusual to go over to week 9 and 10 if the hairs do not change...

hey mark, great site, great information! I would like to know what are the risks of growing at temperatures around 36 celsius? Currently that is the kind of temperatures my room is experiencing and I am concerned for the plants. I suppose they encounter these temperatures when growing outside, but I believe I heard something bad about it for indoors. What are some strategies to bring the temperature down? I am worried about running an air conditioner on a 15 amp breaker with the light and carbon filter fan already on it. What are my options? thanks so far for all the help.

WEBMASTER:  ..these plants consider it stressful to be above 30C and they will stretch and leaves will twist, roots will slow their intake of nutrients, mites and other pests will find her for sure...... all around problems......you can NOT run a light and an air conditioning unit as it will trip a 15 amp breaker... get an extension and plug the air con to a kitchen socket as they are 15 amps as well.... the only other way to bring down the temperatures is to increase the power of your outtake fan.... the more air you move the better... a 400W needs 80 CFM, 1000W 150 CFM... CFM being a rating of the inline fans (like this).... do not use any other as they are a waste of money (like this)....

HI Mark!! I found what looks to be a male, It was odd because it was the shortest. (that is odd) But It has many ball sacks, I made this decision ONLY due to pre-flowers- its been growing for over 2 months, was it a good decision to take it out of the room. (unless the plants starts blooming I would not be able to be 100% sure its a male) The Other two are now 2 feet tall. I need to take cuttings, but I do not have a separate place to put the clones, I have a closet 6x6 I am using, with a 400W MH , 2 32 W 4ft fluorescents and 2 small 15 W fl. I want to make a small box out of the fluorescents, but i am worried about leaking light and designing the box in the same room i flower in .(Unfortunate there really isn't anywhere else) When I take the cuttings, the original plants will need to flower in a few weeks, So my ? is there no other way of taking clones, and then flowering the plants, and keeping clones to growing in veg, other than have 2 separate places/rooms right? (the two spaces need complete separation of lights otherwise the bloom part will suffer, which is possible if you do it right) I am going to cut the plants in half when I do the cutting, My tallest plant is over 2 ft tall, So I take the cutting, and then what do I do with the top, Take of the main stems at the bottom and use those for smaller cuttings, and then have a big main one, or...?? (you take cuttings from the top , down... not from the bottom , up... leave the lower branches alone and they will become dominant within a week after the cut) Last one, My room is 34 degrees, Is this too hot for the plants, it goes from 27 when i start, to 34 during mid day, and all throughout the day, then cools down at night. I read a cooler room produces more females. (totally true but unless you can get an air-con or better ventilation there is nothing you can do) Last thing really, I noticed on what I think is a female/hermie. that it had 3 little hairs coming out where balls/sexy parts come out, it isn't balls, It doesn't look like my male, its just a row of hairs. This is just a little something that I am guessing is due to light hours being not timed at all and a major change of lighting, but what?

WEBMASTER:  ..make sure they get minimum 18 hours of light when they veg.... I can not really tell 100% if the plant is male or female unless I bloom the plant or their clones... I do not know if its a hermie or a male..... these are very "if-y" issues... the only way to tell is to bloom the plants....

hey bud how are ya, quick question please, i have an authorization to possess dried marihuana and know want to apply for the cultivation for personal medical marihuana, can u help me with this? . thx god bless

WEBMASTER:  ..you need FORM C from this PDF file... see pages 13 to 16... I will explain by Heading... C1: Applicants Information... easy... you data...and fill in your current possession license number C2: Production Site... check the first box... you will produce it yourself.. right?... C3: Mode of Production.... indoors or outdoors is your choice.... C4: Security Measure..... you have to say in the first line under "Please describe the security measures that will be used at the proposed production site to protect your crop of marihuana against loss or theft:" you have to say that you Main door of your house/condo/unit is locked with a dead bolt and the grow room is hidden from view and visitors, also you have to say that the door to the grow room is locked with a dead bolt as well..... In the second section where it says "Please describe the security measures that will be used to protect your dried marihuana against loss or theft:"... you have to say that the marihuana is stored inside a cabinet locked with a heavy lock...and it is hidden from view of any visitors .... sign the form and send it to Health Canada...

Hows it goin Mark, I have a total of 800w Hortilux HPS so as per my last ? below u suggest that over feeding is for 1000w ONLY or could i get away with a slight overfeeding?TYVM n TC

WEBMASTER:  ..you can but you need to first overfeed a couple of plants (a test) and watch them... slowly feed them more and more and when they die (IF)... note how high you can take the rest of them.... example: if you overfeed two plants by 40% and they are ok after 48 hours, on the next watering cycle overfeed the rest of the plants by 20%... you should never be higher then 50% of recommended as this would be a 1000W territory.....

Hey Mark i was just wondering what kind of nutrients u use during a whole cycle?

WEBMASTER:  ..I like Pure Blend Pro as well as Flora Nova, good organics... currently I use a bran-less A and B formula ... same as DNF and Tiger Bloom.. they are all the same in the end but none are organic... I do not use super thrive or Fulvic acid or any other additives.... I do however bud boost the plants in week 5 and 6 of bloom with Monster Bloom or PK-13-14 or Miracle Gro Ultra Bloom 10-52-15 (not 10-30-15)...

how would one find out how to feminize a plant. Thanks for any help. wishing to get stated.

WEBMASTER:  ....take a female plant and put her in a cardboard box so she feels restricted.. place her on a heating mat.... so she is subjected to above 30C temperatures ... bloom her.. due to stress she would become a hermaphrodite plant, with both female and male sexes.... now place this hermie plant among other true females already blooming at the same time as the hermie... the male part of the hermie plant will pollinate the true females and those females will produce true feminized seeds... the seeds from the hermie plant should be discarded as they are hermie as well..... eat them they are delicious and full of nutrients, no joke.....

Any guesses as to what I might get if I ordered one of the variety packs you have on hand now? Thanks my friend!

WEBMASTER:  ..i seemed to mixed up some wwxxx and hindu kush with fast pine... so that's the make up of the variety pack these days .... but it could change....


Comments

Mark- Im curious as to whether you have any experience growing in extremely sandy soils such as river floodplains. How did it work out? Any special problems associated with these soils? Thnx in advance...

WEBMASTER:  ..I have no experience because this type of soil is usually in exposed locations where people can easily see it and steal it... whenever I grew in it, it ended up stolen so I .. just do not know....

Hey Mark i am 19 days into bloom and i had bought BANG and DR DOOM, but i was wondering since i am only 19 days into bloom would it be OK to use Dr DOOM on my flowering plants as i bought it for me mothers and i don't have MITES (BUT I DEFINITELY DO NOT WANT THEM either) also i was wondering when i should add my KOOL BLOOM and at what percentages, also would it be on top of my regular feeding, (yes) O and also when is it appropriate time to start over feeding. (4th week when using 1000W only)  TYVM N TC u da man ;)

WEBMASTER:  ..if you are careful you could spray just the bottom of the plants .... up to 4 weeks into bloom its ok if you're careful... do not spray it on the top buds.... kool bloom should be added starting in the 4th week of bloom and finished at the end of week 6 ... start with their minimum dosage (as on the lable) and increase it slowly tough this 3 week period (to their maximum dosage).... generally I add this stuff twice a week with or without the normal nutrients....

Hey dude howa it hanging me its great so a newly licensed grower do i have to buy Ottawa weed for the first 4 months or can i buy from the usual source take it easy or anyway u can get it

Hey Mark ... Couple of questions for you ... This first question is really just a curiosity thing as I don't plan to keep any males anyway. I have read twice now (on other websites) that allowing pollination of a female plant results in a MUCH LESS potent bud, the reason being that the plant puts energy into seed production thereby taking energy away from resin production. This doesn't make a lot of sense to me, I mean, I can see what they are saying and yet I find it hard to believe. What do you think? The second question is this: Forgive my inexperience, but, how long can a mother plant be kept alive? If the answer is 'virtually forever' is it just a matter of pruning etc. to keep it active and healthy without pushing out through the roof? (Sativa) Thanks so much Mark! I am continually amazed at your dedication here.

WEBMASTER:  ..I find that whether I have seeds or not the smoke and the quality is the same.... in fact I could argue that seed production permits the plant to go through the entire life cycle properly thus producing a fuller and better smoke..... but that's my thoughts on that.... a mother plant can be kept for between 6 months and 12 months... after that the plant lives but it falls into a sort of a "coma" and it grows very very slow.... for cloning purposes I would keep a mother plant for no more then a year and replace her with another mother.....

What is the best way to attach plants to a bamboo stake or is being close to the plant good enough? Been reading that it is good to stake plants but can't find information on "How To". Thank You For Helping.

WEBMASTER:  ..you have to attach the stem of the plant to the bamboo stick with a plastic twist tie or rope or garbage twist ties...I generally stake 4 or 5 bamboo sticks per plant and run a rope around the plant for the rest of the branches to find support (without attaching them)... not too tight and be gentle.... another way to learn is to read about staking tomatoes... its the same thing...

hi there mark, i had a question regarding "super cropping" say i had a plant about 16 inches high and i wanted to super crop it, what would be a good size to crop it down to? and where are appropriate places to trim the plants? also, can i trim all branches down or just the main one? one more question to this: can the plants have their leaves touching one another or should they be totally free on all sides? touching is ok... do not remove leafs just because they are obstructing another leaf...

WEBMASTER:  ..I would cut the top half of the plant... down to 8 inches .... see if this helps....

Hi, Im planning on buying a used 400 W MH OR HPS. In your opinion, is one better than the other? The HPS comes on a tripod-y stand, and would not be hung, put placed over the plants with re adjustable poles to move it up and down. I would get 3 bulbs, 1 new, 2 used. The MH is with ballast, So would be hung, and comes with 1 light. and IF i am going to buy a new grow bulb with plant spectrums, which light system would be better for it. Mark, You are the Pot King. Thank you, goodbye.

WEBMASTER:  ..if you are never (ever ever ever) going to have a separate veg room get the MH ...its best for both veg and bloom (get SunMaster bulb to compensate for lack of red spectrum in bloom), if you WILL have a separate veg room eventually, get the HPS, because it does slightly better in bloom (to compensate and get more blue spectrum get the Hortilux brand bulb).... Marc Emery is the Prince of Pot and the current Pot King... may be dr. green thumb :-)

hi, im looking at your "house brand" strains, and im wondering about which strain i should buy.....just from Toronto420, no Paradise or anything... i hate saying this, but im sick and ive been growing for almost 15 years, and i have the same genetics from a ways back...dont even know what they are as they are "bagseed" from some friends bag....i want a strain that i know what it is, how long it takes, i can talk about it and ask questions with other people that grow the same strain...know what i mean...been growin an "unknown" strain forever...im dealing with Hiv and ive got serious stomach problems once in a while....i see u have strains that are perfect for that....BUT...i really need something with yield...i mean somethin special....and preferably not a SUPER smelly one (i have a CANFilter, but still don't want crazy smell).... im practically on my way to ur shop...when u open.....but i cant decide from your strains what to get..... consider that im not gonna grow a bunch of different strains, this one has to be special potent/yeild.....this would be the FIRST known genetics i ever buy! and about yield, i always seem to run out before the next crop is ready.....i know what im doin, in lay pebbles, 1000w air cooled in a 4x3 in 5 gal buckets, c02, advanced nutes......i just always run out....i think my strain sucks for my skill level....i need the best yielding strain ever...but im a connoisseur as well...so that's why its so tricky for me...... it just has to be fat and potent, and not a stretchy one..... sorry for the long read, but im really sick of my shitty strain, and im coming by ur place soon, and i really need the good medicine already, as im frigin immune to my 10 year old strain...and she hermie's every so often...(funny i know)...... PLEASE help me out....ohh! and i also really HATE HATE HATE the sleepy stuff...the fact that MY strain gives me energy and makes me smarter and more active is one reason ive had her for so long, and a BIG reason why im SUPER healthy, and strong and still alive, so i definitely don't need a couch lock strain... sorry, im a complicated bitch! hehehe im sorta leaning towards the Blueberry skunk, but is it really stinky crazy smell?? and the fact that it has blueberry, is it a shitty yielder?? (good yield) and is it a good to smoke all day long, with good medicinal value?? (no read below) (hate nasty hashy throat pains (leach them more this will help)) and how's the g13 x buddha (good sativa smoke but bad yielder when bloomed too small)...what else can u tell me out it that might pertain to my situation, would it be good for me? are the yeilds fat?? (only is you grow them big, 10 gallon containers, 4 per 1000W light) Thanks so much....i know im crazy for this long post!

WEBMASTER:  ..you want two opposite things.... big yield and Sativa dominant strains.. sativa is the up and happy and motivating and daily smoke.. sativa and big yields do not mix well, that's why street weed is 99% indica, big yield... in order to make a sativa strain yield well you need to grow them big... outdoors is perfect for this..... summertime buddha, white widow buddha, are 80% sativas BUT blueberry skunk is 80% indica and it will make YOU sleepy... it works for me and I stay away from sativa since I need to de-motivate my self i.e. come down with a nice heavy indica.... it is really a personal issue, you should try 5 seeds of 2 strains instead of 10 of one... in the end how it tastes is personal.....

I got some seed from you [skunk fem] starting it between wet paper towels (in darkness?) it has been 2 weeks and still not sprouted bad seed or did I do something wrong. I kept the towels damp never dried out and kept temp 18-20c. Just wondering bad seed in plastic bags to long seeds have to breath to. Any help with this would be greatly appreciated. Thank You

WEBMASTER:  ..I would not keep them in plastic bag, they need to breath but that is usually not the problem.... send back the card the seeds came with and I will mail you a replacement....

Mark, 1000w light on a 4'x4' table, 6'x7'x7'room, good vent...clones...Heavy Indica.... How many plants? How big should the pots be? How tall should I veg them before bloom? If you can answer these 3 questions .....you the man! \

WEBMASTER:  ..20-25 plants in 2 gallon container, keep some side branches, veg to 8-12 inches or 40-50 in 1 gallon containers, cut all side branches, veg to 6-10 inches ..from clones..... from seeds 10 plants in 4 gallon containers, keep 5 females, veg time 1 to 1.5 months, veg to 24 inches....


Comments

Hey Mark its the dog again so i get a license to grow 20 plants So now i got 10 in bloom and i make 10 clones does this mean i got my 20 plants or can i have 20 in bloom and mo clones so the question is does our clones count as one plant of my 20 thanks alot dude

WEBMASTER:  ..unfortunately the way Health Canada and the Police look at this issue is that a plant is a plant from the point of clone to maturity, so it does not matter that you have (examples)... 10 x 1000W lights in a warehouse and 20 giant plants in ten gallon containers OR you have 40 small clones under 40W of fluorescent light in your closet..... you could be arrested for those 10 plant over your limit........ you should keep 2 mother plants and have 8 to 10 clones always ready to be bloomed.... this way you can have blooming plants in different stages of bloom..... 2 plants over the limit is not an issue from what I heard and the regulations are very unfair.... and as long as you are not exceeding your possession weight limits you probably would be ok....


Comments

hey mark im 9 days into bloom and out of 19 plants i got 1 hermie and 6 males, is this normal? seems i had a few too many males but its my first time so i don't really know what i should get in females/males ratio, and 4 of the ladys are ur feminized skunk69.But other than that its goin well i think lol. TYVM n TC :D

WEBMASTER:  ..playing the odds... you seem to be a bit less then average... stress causes this + luck + skill.... I find that its easier to have a small veg room independent of the bloom room and have a mother plant with clones... this way all you need is 1 female and you can re-clone her into many female clones.... a veg room/closet needs at least 80W fluorescent lights, say 1 foot wide, 2 feet long and 3 feet high......


Comments

Hi Mark, I am in day 52 of bloom, I have been growing 4 wwxxx plants under a 1000w hps. I have read in your forum and seed bank, that if i turn the lights out for 2 weeks and leave them in darkness they will get VERY sticky. Right now they have minimal frosting on the buds.......I could spare a week of darkness, will that help????? thanks man.

WEBMASTER:  ..yes, it will produce more trichomes, i.e. make it more crystalie/crystally(sp?) ..... the two weeks of darkness are in addition to the 8 weeks of standard recommended bloom...... personally I would not do it as the yield suffers... not by much tough ... and the two extra weeks could be used for veging new plants...

the Police... why don’t you catch a rapist or catch the murders that are free? Do you know how many murders are roaming the streets of Toronto that the boys in blue have failed to capture? Better yet, instead of using your Internet usage privileges for these miniscule acts of trying to intimidate the users of this forum and ruining the hard work of Mark who is conducting himself according the law…yes the same law that was put in place by those who pay your salary Mr. Swine... allow me to finish my point… instead of using your internet usage privileges for learning how to grow for medicinal purposes… why don’t you find child pornography… has our constitutional rights of being a Canadian become so much like the Americans that even law abiding citizens who pay their taxes (Yes Mr. Swine the same taxes that pay you salary) are under surveillance?… Mr. Policeman please spend your time doing something more productive and reasonable.. Do you really think someone will place their address or real name on this forum? Or maybe your looking for a technicality to shut down this site… well Mr. Policeman your intimidation and scare tactics will not work here.

Hey Mark.. just pondering the pros and cons of using vertical lighting in terms of total yield. what i mean is instead of using a reflector and spreading light across the canopy.. why not put the bulb in the middle and spread the plants around the bulb such that the sides of the plant get light (yes, generally when you have big plants but few of them).. i was thinking that the plants would need daily rotation to ensure equal lighting on every side. (yes, quarter turn every day).. however the number of plants that can be grown in this manner is less than the number you can grow if you use a reflector (thus the trade off)... i just want to maximize yield... maybe you need to veg longer however will there be a higher yield? any comments or suggestions... thanks brother.. (some strains yield better when they are big some when they are small some prefer slightly more nutrients and some do not, but as example, fat skunk would be the plant that yields better when it gets bigger and yields a bit less when bloomed small) 

WEBMASTER:  ..this is what what I do when i have mother plants used for clones but I find that the method requires that you have few but big plants... example is that if you have 5 plants under 1000W the you can place the bulb between rather then above the plants.. yes daily rotation is necessary.... but if you have 10 or more plants then its more efficient to have the light above them .... with 5 to 10 plants it is up to you to figure out what's best since each strain and each light and each closet work together differently... about light: I am totally with you on this issue since reflected light loses 50% of its power... so I generally prefer to have a minimalistic reflector so my light goes directly to the leaf.... I always chose small and easily bendable reflectors.. so I can bend it always from the bulb.... you do not have to remove the reflector, just bend it away from the bulb so it prevents the lights from reaching the ceiling but is still mainly exposed to plants....

Mark ... you should be able to get the I.P. address from the 'Police' submission, right? Check it out and see where it originates from.

WEBMASTER:  ..you should always remember that the police does not warn you when they monitor someone.. I also must say that they can SPELL VERY WELL.... also I disabled the IP tracking function precisely so no one can track the IP of anyone who post messages... the most they can track (after some fairly expensive court orders and lots and lots of man power) is the main hub of the last server processing the message.... not to mention that hunting for growers who grow 5 or 10 plants is VERY VERY expensive and I am currently not aware of ANY busts resulting from the Marc Emery affair and THAT was a BIG one...

Your forum is tracked by our police division. Any trafficking is strickly prohibited and we will take the required actions as necessary. We have already arrested 2 grow op owners who have allegedly purchased seeds from this website, and although we are aware that nothing illegal has occured, we are in obligation to warn all other at this time. Please do not grow your cannabis plants if you are not authorized to do so by the government. Monitoring of this forum will be continued. you must be local Toronto police since if this was RCMP it would say "stop growing whether its legal or not"...

WEBMASTER:  ....I hope the police can spell better... but to emphasize the nature of our goal .... I would like nothing more then to explain to the police the process of cultivation of cannabis plant indoors... it would help an average cop distinguish a personal grow closet from a "grow-op" and not freak out EVERY time they see a license to grow..... I already send in my resume to Health Canada and the RCMP in order to be the first to really, I mean really, explain what growing cannabis is like.... I am very personable, direct and above average speaking skills... in fact please feel free to read this FACTUM (assuming you are the police and you know what it means) which clearly points put that Canadian police know next to nothing about cultivation of cannabis.... its not an insult .. DEA knows since they grew their own pot to find out what you can do with a plant ..... I can teach you... only knowledge can enlighten all of us, those who fear pot (even tough its legal to me and 1500 Canadians) and those who love it...... please feel free to monitor this forum and enjoy.... I could go on about freedom of speech and my rights, my rights... but you already know all that....

hey bud, how are u today., i got 15 hash plants on the go. I flipped the ladies 2 weeks ago at apprx. 10-12", today they are around the 2.5 to 3 feet tall and forming already, do i keep the light at approx. 2 feet away at all times. they look great and cant wait to taste the medicine ..thanx alot and have a great day.Oh by the way i called health canada to find out when renewal of cards should be done, they say it is about a four month deal. my card is up in sept.07 so i am reapplying now because well u know them, in reverse for the people. Again thanx and renew early, god bless

WEBMASTER:  ...i find the hash plant to be a well balanced (60%) indica and (40%) sativa strain ...

i have 9 plants 40 days into bloom under a 1000w hps. and all the older leaves are going yellow with brown spots and are getting crispy and the hairs are curling up, this has been going on now for a couple weeks , i am growing in pro mix and am using dnf bloom, and have added dnf bloom fortifier once..

WEBMASTER:  ..this is a fairly normal process that blooming plants go through... the older main leafs tent to die off first.... you over watered them combined with slight overfeeding, next time around you should preventatively leach the plants with 25% nutrient mix every 3rd or 4th watering cycle....... there is no real way to fix this... you should pull back on nutrients for two watering cycles and most likely do not water the plants as often as you did.... try to give them an extra day if you can between watering..... do not water with plain water.... add 25% of nutrients for two watering cycles.... they will continue budding...


Comments

how can you revive a plant that has some purple stems developing?

WEBMASTER:  ..mix exactly 20% of your regular nutrient dosage in you the water,..... if you give her plain water she may get worst, but if you give her full feeding she will overfeed..... at 20% or 25% nutrient level the roots will get clean (since you may have a salt build up if its overfeeding) without withdrawing the nutrients completely, which would cause nutrient lock..... in short water her with a wee bit of food.....

Hey Mark... need ur expertise... lets say u have a satvia strain under 1000w bulb... how many plants would you place under each light to prevent stretching... i like plants to have a thick base stem, but does it really matter or is each plant different?... currently the stem is not thick and the plants are tall.. i cant tell whether they have stretched or if its just the traits of a sativa strain... is it better to cram more plants under a light or to put fewer plants so they have more space to prevent stretching... i'm talking in terms of yield.. the strain i have is a very very potent sativa strain.. again i am having difficulty determining whether the plants have stretched or whether its natural for sativa to grow in such a fashion.. any advice would help.. thanks brother..

WEBMASTER:  ....make sure your bulb is not over 10 months old as this would stretch plants as well..... sativa stretches naturally and there is nothing you can do... in general when I know I 'm growing a sativa strain, I would trim her twice when in veg so the plant gets bushier .... once in bloom try to find a way to support each and every branch.. the less they move the more yield you'll get...... when you bush out a plant, each bud is still stretchy and small but at least you get more branches with this stretchy and small bud.... sativa is notoriously bad when it comes to yield.... with a sativa its better to grow them big , like in 10 gallon containers vegged for a month..... this I find is the only way to get the minimum yield ..... so with a sativa plant under a 1000W I would be more then happy with a pound of dry bud.... with a heavy indica I would expect 1.5 and hope for 2....

What size of exhaust fan and filter would be sufficient for a 8'lx4'wx7'h room that contains 2 1000w bulbs. Which lights would you recommend as this room is bloom only.

WEBMASTER:  .....in a basement with an exhaust line not longer then 10 feet you can have a 200 CFM fan and a carbon filter (example), .... if your line is longer then 10 feet and / or you are in a spot where it gets hot.. this being summer... I would get .... 300 CFM and a bigger filter.... for lights I would get 1 MH and 1 HPS.... bulbs brand name matters little as long as they are new.....

hey mark! i would like to ask u what the smallest space i could grow in using a 600w HPS? the reason is that my closet is 2 feet and 8 inches deep by 4 feet 6 inches and the hight is more than 7 feet tall, would this be enough? i plan on growing 5 plants (your skunk 69) and im worried about the size of my space. i do not have my fans bought yet, so perhaps you could tell me what cfm fan i should get for this space as well, that is if you think i should even bother using my closet? summer is practically here and im also not sure if the heat we get in summer would be too much for the plants in my space? considering the size of my space, do you think this would affect my yield? (heat in the summer as well as the sheer size) i hope to get the maximum i could possibly get with my light. i think this is all the questions i have for you now, i hope this is not too many questions. aside from all this i only have good things to say about your services, i read your grow guide and this forum all the time, i recommended you to all my friends and i have most of your seeds too. thank you and peace in the middle east!

WEBMASTER:  ...3'ish by 4.5 feet space with a 600W light would theoretically need about a 100 CFM inline fan, 150 CFM if you add a carbon filter or push more then 10 feet of air ....... that's if this is in the basement... if you are on top floor and the roof heats up in the summer, you may need 200 CFM fan....  5 plants vegged for a month (from seeds it take 1 week to sprout, 1 week to show something resembling a plant, 2 weeks for serious veg time growing to may be a foot or 2) and about 8 weeks of bloom.... your pots should be at least 5 gallons or 12 inches.... I would probably add a week to your veg time because I would snip off the tops when the plants reach about 5 inches... it takes a week for them to re-grow so an extra week gets them more bushy and thus more yield....

hey there Mark did the paper towel thing never dried out had them in the doom humidity was 82 to 87F and i store them in original package in my strong box oh yes was only 10 seeds

WEBMASTER:  ...send me or come in with the little printout/card the seeds came with and you can have a pick at 10 free seeds.... whatever the reason ..... in general I would store the seeds in the fridge (not freezer)... in a light tight container.... otherwise they may dry out.... I prefer toilet tissue over paper towels.. its softer... but it does not mean the paper towel was the problem.... I also emphasize that when you are sprouting them they need total darkness as they often sprout a root first and roots hate light....

hey mark.. i got this bottle of DNF gold and it says that if you do a foliar spray during flowering it will produce more flowering sites and make the buds more stick icky... is it true or just a marketing scam?... i don't whether is Fulvic acid or what it is... but any advice would help... thanks brother...

WEBMASTER:  ... I believe I had only one person raving about this product and it does not sell well over all (what I heard), if they simply relabeled it as Fulvic acid they might have more luck....... from what I remember its a type of Fulvic acid from a tree (as opposed to??) .... in general you should treat it like Fulvic acid and you could spray (with a fine mist) under the leafs every 3rd day and try to avoid the bud itself... its good to have good ventilation..... I do not really understand why they want you to add it to your water all the time... and to be honest.. if they price does not scare you it won't do any damage... but I try to add Fulvic only once (when watering the pots) when in veg and may be twice when in bloom, and give them a weekly (light) spray once a week in bloom.... but I do not do it at all in the summer, too hot, mold may be a problem.....

a follow up to my previous question regarding seedlings outdoors: once they have sprouted, can I keep the seedlings on a bright window sill (lots of light, but no direct sunlight) or should I put some money into a daylight type bulb and grow them for a week under that?

WEBMASTER:  ...I do not think you should spend any money first time around, after all you can always spend money for the autumn or winter, summer is good for us.....sprout them in the dark, transplant and put them on the window sill but when they get over 5 inches move them to direct light.... a cheap fluorescent bulb would be ok if you want to take cuttings and sex them (bloom the cuttings to find their parents sex)...

Hi Mark ... I'm sure you're very busy but I would appreciate it if you could help me with your suggestions. I am ready to order seeds and would like your advice on which strains to purchase as per my needs. I plan to buy 2 strains, 1 for daytime use (sativa/up) and 1 for sleeping (Indica/down.) This information should help you: I am using marijuana for pain, nausea, stomach problems, depression and as a sleep aid/pain killer. I am a beginner so the easier to grow the better. Also, low odour would be beneficial. To summarize, I need an energy booster and a sleep aid that will assist with the health problems mentioned. Thank you so very much. Your help means a lot to many people - I hope you realize how much we all appreciate it.

WEBMASTER:  ....anything 80% sativa is for the up feeling... all the strains with BUDDHA in it are 80% sativa.... for the sleeping effect get the wwxxx or anything with 80% or more Indica in it.... with indica extend the bloom cycle by one extra week and you will get even more sleepy bud..... you should try to get Health Canada card or at least join a club in Toronto.....

Hi Mark it's me again. I was just wondering. I'm starting 4th week of flower. You said you should use blooom enhancers all the time at the 4th week at weeker levels or twice at a stonger level in the 4 to 6 week period. when you say extra how much roughly do you add. KOOL BLOOM sais to use 1.5 grams per 4 litres, DNF BLOOM FORTIFIER sais to use 2.5 ml per 22.7 litres. Could you please tell me what you would use. Thanks again and I will be seeing you soon. Hope everyone is managing Ok. PS keep up the good work. By for now.

WEBMASTER:  ....under 1000W I could up the formula by 25% never more then 35% for fortifiers..... when it comes to DNF A and B (only) I could add 100% more .... but this is based on my experience of looking at the plant so take that as a test.... test it on a plant or two first....

Hello Mark, Will be taking a trip to the Toronto area for a convention and would love some advice on some do' and dont's (other than the common sense ones) on trying to locate some bud while in the T area. Also whats your opinion on the best route to take to locate some. Thx much! Regards Colashiro

WEBMASTER:  ....your friendly bike couriers.... delivery bike couriers downtown... just ask

hey there dude just germinated our blueberry skunk seeds bought then last year from you was kind of disappointed with the results of the seeds got only 3 to take is this because a waited a year or i did something wrong

WEBMASTER:  ....how did you germinate them, how did you store them and how many did you buy?.... could be many reasons....

Hi Mark .. Super job here - keep up the FANTASTIC work! My question is about lighting. I can't recall seeing anything about Halogen lights in any Grow Guide. Are they considered the same as fluorescent lights or do they simply not put out the necessary 'rays.' I have a dual 500 watt Halogen 'Work light' set that is extremely bright and emits a lot of heat. I realize brightness does not equate to essential UV and other rays, but I thought at the least these lights might be useful as a heat source since they don't cost much to run and put out a ton of heat. If they were useful as a light source also they might be a great thing to use. Do you know much about halogen lights Mark? Is this just a stupid idea thought up in a moment of 'revelation?' :~) Thanks so much for answering. You are amazing!

WEBMASTER:  ....the halogen lights give off more heat then light... in fact so much heat that they will most likely burn the plants.... I do not know anyone who was successful with these lights.... don't get me wrong ... 500W is a lot of light but you will not be able to control temperature .. I guarantee it....

ive come across some clones that were reverted back into veg from bud (early girl ) im pretty desperate for clones and have no choice but to buy them. am i wasting my time with these clones ? should i expect a small yield ?there is 35 of them they have been in veg for a month in a half and are ready to go outdoors .

WEBMASTER:  ....it may take 2 months before the plants start veging after being pulled from bloom.... the bigger the plants the quicker it happens but ...... I would not want these clones..... are they even showing signs of growth?... if they are then they are ok but if not it could be a total waste....


Comments

Hey mark it's me again lol. I have another question regarding Pro-mix BX. After I'm done harvesting my plants using this soil, can I recycle and reuse the soil? IF so, How?

WEBMASTER:  ....if you pull out all the roots (more or less) and add about 20% fresh promix you should be ok to do this once.... then you have to replace the whole thing second time around....


Comments

Hey Mark, I just got your seeds in the mail and had a few questions for you. I would call you and ask only i thing that the answer would benefit more people if i asked here. 1)You use the term flowering period. What does this mean? Does it mean that the plant will produce buds for that period or does it mean that the plant will have to gro for that period in order to get buds? 2)My plans to grow might be delayed, in general how long can cannabis seeds last if they stay in the bag you supplied them with and in the absence of all light and water? (with no light and no water, placed in the lower part of the fridge should last for years) Thank you for your time in hopefully answering my questions, I will definitely come to see you the next time I purchase seeds. P.S. You are a very reliable seed bank as to delivery i will let you know how well your product is soon;)

WEBMASTER:  .....as you start seeds, and grow your plants, your main light is ON for at least 18 hours a day and this is called the vegetating period, the longer you prolong this period the bigger the plants will get BUT they will not produce any bud/pot........so the answers to question #1. flower period starts when you switch the timer (on your light) to 12 hours ON and 12 hours OFF (sleeping time)....once switched you can NOT switch it back, you have to take them to the end of 8 weeks...... when you start the flowering period the plants start to produce buds, on the average this period lasts 8 weeks and you have to cut down your plants (i.e. harvest) at the end.... it is crucial that when the plants sleep NO LIGHT of any sort gets to them.. EVER....

Hi Mark ... Absolutely amazing site here and your dedication astounds me. Thank you thank you thank you! I will be growing for the first time (and ordering seeds) within the next month. I have spent the last couple of months learning all I can before I start. My question is this: How critical is it to germinate the seeds using the paper towel (toilet paper) method? I would prefer to simply plant the seeds directly in the soil mix because I don't see very well and am afraid I will screw up the root. It's possible I could even plant them upside down! (NO) I don't expect any problems once I get started as I am very patient and somewhat experienced with other plants; however, I am a little worried about the germination process. What do you think? Thanks very much!

WEBMASTER:  ... you can of course simply place them in the dirt and keep it wet for 2 weeks at least.... I do not like this method because the seeds are expensive and the toilet tissue method if far more reliable..... its one thing to plant (example) carrot seeds at $1.29 for 100 seeds and cannabis seeds at $5 per seed...... in other words chances of germination can be as low as 50/50 when in dirt... and 90% when in toilet tissue.... I would not worry too much.... this germination method I learned from my grandmother....

Hey Mark I was playing around in the room all stoned out of my brain.. and i was replacing a digital timer... like a pothead i forgot to turn the timer onto AUTO before i left... So the lights stayed ON for 24 hours straight... is my crop totally fucked? im going into my 4th week of flower.. thanks

WEBMASTER:  ...definitely damage occurred.... I think you can safely extend your cycle by at least a week and the bud may (MAY) taste a bit too fresh.... also 1/3 of your yield is gone.... for personal smoke it should be ok tough....


Comments

hey mark i sent those pics to ur new E-mail. Also i was wondering what ur thoughts were on the ADVANCED NUTRIENTS products.

WEBMASTER:  ...if its the pics with the male pollen sack I think I replied to you by email... in short no big deal, chop it off... I'm ok with Advanced Nutrients, just a bit expensive...


Comments

Hi Mark, Great site, thanks for all your hard work. I am growing in pots outdoors, and wanted to know if i should start the seeds in the promix outdoors, or germinate them in paper towel and then move them to jiffy pots outside? Or do you think maybe it is still a bit cold to have seedlings outside? I've got a little greenhouse that should keep them warm... anyways, let me know your thoughts.

WEBMASTER:  ...start the seedling indoors, baby them for a week and when they are few inches high take them outdoors.... by all means use the greenhouse if the temperatures are good, but do not plant them outdoors yet as nights still get pretty cold....


Comments

I was wondering if it would be a stupid idea to move my few plants out from under the 400W HPS and put them under my skylight when its really sunny out for a few hours

WEBMASTER:  ...it is a good idea as long as you get a clear day.... they should get more lumens from the skylight then the 400W .... there may be some wilting at first since the sun may overwhelm the plant but you can just push it to the side (with less direct sun exposure) for some time ...

skunk 69 is rather odorous when veging Mark. today I just switched to bloom time. will your sweethearts generate stronger smells?? just wanna know if I should purchase a more powerful exit fan. also.. I know you said to not let them touch I only have a 3x4 space plus 3 6" fans and the (3 of 5 seeds growing) have bushed more than I anticipated (10"pots) so they are touching each other but not really crowded. the 2 seeds that did not come to life are back in the original packing. do you want to have a look at them for research purpose?? I almost cant wait to try out the 69er buds. I have a sleep condition due to shift work and the indica side of 69 I hope will help with such. Thx for being you and this awesome website!! Your education too all is invaluable. .....

WEBMASTER:  ...get some supporting sticks (bamboo or plastic sticks) and use them to support the larger stems ... this will restrict their growth Up instead of sideways and also allow the buds to get bigger since the plant will not have to waste its energy on supporting the heavy stems.... in simpler terms do what people growing tomatoes do... support the plant ... do it now, since for two weeks they will grow... then they will stop..... what is the CFM rating of your fan .... often its right in the name of the fan.... is it inline or squirrel fan? and what kind of light do you have.... I prefer to spend my money on kick ass ventilation rather then on fancy reflectors, so yes, you should upgrade if the smell is bothering you now....


Comments

I have read places that blueberry is a little harder to grow than your average strain. Does this apply to the Blueberry Skunk seeds you carry?? And do you have more detailed information on Blueberry Skunk? Thanks Mark!

WEBMASTER:  ...I found either strains easy to grow... often when a strain is a bit more sativa then indica she needs regular feedings at 80% of recommended when a heavy indica would want 120% ..... some people may end up burning a sativa when an indica would love it... blueberry skunk is 80% indica so it can take some abuse beginners often make through trials and errors....


Comments

How do I get a supplier? Seriously how does one start to receive cannabis if they want it? Hope you reply.

WEBMASTER:  ...I reply but I am not sure how to help you.... you have to be a medical user....


Comments

oh and dont go with a used bulb kiki....new bulb is the only way.

WEBMASTER:  ...that is absolutely true... used bulbs (even if its 1 month old) are worth $5....


Comments

try ebay for used equipment kiki....there's lots there.


Comments

Hey Mark I'm looking for a second hand light and ballast that is affordable because I'm looking to cut down on my expenditures. Could you direct me to a place in Toronto I would be able to find this? Thanks very much. Kiki

WEBMASTER:  ...at this point I do not have any used equipment ..... I bought stuff off of Craig's list and eBay but I am not aware of any stores that carry used equipment....

Hi Mark, what is the best temp. inside a dome when first taking clones. I have heard that 80 degrees is the temp. you want under the dome for the 5 days. What is your mist technique 3-4 times a day? thanks in advance.

WEBMASTER:  ...temperature should be around 80 to 85 F, humidity around 80 to 90% for the first 2 days and on the third day I remove the dome completely so the clones can get used to the outside temperatures... 80F is fine...... when under the dome I do not spray but once the dome is off I spray twice a day.... once a day after 5 days.... and I put them on a heating mat once the dome is off....


Comments

Marek, is it possible to achieve 1 pound per plant outdoors and how spaced out would the plant need to be to achieve that, if i was packing in plants and i was putting one plant every foot what could i expect to yield per plant and what do you recommend in terms of nutrients?? When do i switch from veg food to bloom food??

WEBMASTER:  ...1 lb per plant requires at least 10 Gallon container but better yet if its was right in the ground, the plant would need 5 by 5 feet of space... the plant should be at least 2 feet tall when taken outdoors in mid may ..... veg to bloom switch happens after the solstice... June 20th.... plant plants every 3 feet at least and 4 feet would be better..... about nutrients, scroll down to Point No.6 on this page ....


Comments

hey mark just wondering if you could send me a good link on a good home made hydroponics system i'll be using two 1000 watt hps ballasts ,a good step by step diagram would be great

WEBMASTER:  ...I have yet to see one on line that's reliable and trustworthy... sorry but if you find one let me know....

Hey Mark How R U. Well i just sent u a few pics of 1 of my plants that is 7 weeks in veg and it has what appears to be a very premature pollen sack that looks to be open. IT CAME FROM PROGOLFER1 IT IS A WWxB plant in promix as i removed it from my garden scared os what it will do as this is my first grow TVVM

WEBMASTER:  ... send it to sublime@toronto420.com..... the other email gets spammed too much....


Comments

How do I find a Doctor to sign the paperwork for Health Canada ? Thanks

WEBMASTER:  ...make appointments with doctors and try to get a clear diagnoses of your problem, accumulate as much paper work on your condition as you can.. at the same time ask every doctor you meet if they are willing to sign the Health Canada forms.... in general it takes a lot of appointments .. some doctors are scared and some unwilling ... some will sign...

Hey Mark, I been to the march what a seen that is and sooooooooooooooooo many people it was a greater experience in my life and i had a great time, I recorded alot of it so. I was also wondering what u thought of WHITE RUSSIAN, and KUSH as that is what i will grow next, WHAT DO U RECOMMEND as a great strain. TVM NTC hope u had a good time down there ;)

WEBMASTER:  ...the march was great but I was working so much I missed the actual parade.... I do not like the White Russian as its too much of an indica and too much like White Widow, I am a bit bored with the WW.... Kush is more balanced for me and the smell is better..... either one are easy to grow....


Comments

Hi Mark.....hope the march was good! I followed your advice in this forum to grow from seed then take a clone from each plant and then put them under 12 hours to sex them, and then remove the males. It has been 14 days and the clones have not showed anything yet. I have...some.. experience and know what a male and a female looks like, maybe it takes an expert in the early stages....any suggestions you have would be great as my plants from seed are out growing the area and really starting to stretch.........Thanks

WEBMASTER:  ...the ones that are stretching may need to be cut back... i.e. chopped... the clones if they do not show sex may have light leaking in during their sleep... make sure its pitch black when they sleep and NO interruptions..... 14 days is a bit long... they may be "stunted" in which case another week will pass before you know...


Comments

Hello, about Outdoor growing, how long does it take to harden-off a plant so it won't shock when I move it outside?

WEBMASTER:  ...minimum 12 hours and usually a day.... bring it outdoors into a shade and leave it there for a day... the next day put in into direct sunlight.... if this was mid may (usually the 20th) I would start putting plants outdoors no matter how tall they are....


Comments

HAPPY GLOBAL MARIJUANA MARCH I hope everyone has a great day.


Comments

Hey Marc, what would you say the latest into bloom you can go and still safely thin out plants? There are a lot of small branches that will never see light so it would make sense to cut them off so the top branches get more food. THanks

WEBMASTER:  ...yes it makes sense to cut them off.... the branches getting no light will starve the top buds and produce very little themselves....


Comments

I just want to get this straight, as long as I use Pro-mix BX, I can use my nutrients mixed with tap water to feed my plants, (yes) I don't have to check or mess with my ph levels? (yes)  How many CFM do your recommend for a closet no bigger then 2 by 2 with a 400HPS.

WEBMASTER:  ... I would like at least 50 CFM if its an inline fan..... if you get a standard bathroom fan get the one that says 75 CFM....


Comments

Hows it going Mark, I was wondering if low humidity causes stress like 40 to 50%RH TYVM

WEBMASTER:  ...no... if the temperatures are within 25-30C or 78-83F then humidity is of no issue... also 50% is ok... if its over 75% then I would try to dehumidify.... the smaller the platnts the more humidity they like... a 1 inch plant would love humidity at 75% but a 1 foot tall plant likes it a around 40% to 60%.....

hey bud, how are u, since u are experienced in the hashplant, wondering if u can tell me best week to harvest in? 7-9? i am a mmar for possession card holder planning on applying for the cultivation license next month, anything i should be aware of? will this give those outlaws in blue the right to enter my home when they please, unsuspectingly, u know like roaches, turn the light on and their there. thanx god bless and i dont have roaches hahaha.

WEBMASTER:  ...the boys in blue are very unaware of the Health Canada program so if they come its because someone complained about the smell or noise or something... cops generally do not even belief that you can actually grow pot legally so you have two choices... 1 is to get your permit and report to your local police station and tell them you have this and welcome them in your house... in a day or two a cruiser will pull up to your door a couple of cops will visit you and you will never see them again (I did that with one of my places)... or you can just stay quiet and keep to yourself, if they come you still have a permit ...... hash plant is a good yielder and its a 40% sativa so the smoke is very sweet.... you can go over 8 week but 9 is the maximum....


Comments

how long should the seed shell ( don't know the proper term ) hold onto the the first 2 leaves ... for some reason all my seeds (not yours) are holding on for too long .. and they un-stick and leaving one side with more growth then the other ... sorta mutant plants .. is this genetics or is this me doing something wrong ?? the shell of the seed just don't fall off as fast as i thought it would ... and if it lets go of the one first leaf the other one slows down in growth ... and this happened to multiple varieties (white russian - sugar blossom)

WEBMASTER:  .... you will know whether the plants is bad or good when they reach around 5 inches ..... usually stress factors make plants do odd things..... could be lack of light or over watering.... your temperature should be abound 82F and 70% humidity....  if you are outside of these parameters then the plants may have a rough start but they still may turn out good, as they grow up.... another thing I would like to add... with fluorescent lights you want the light 2 inches away form the top as its not a very powerful type of light.....


Comments

how harmful are fungus gnats and how can i get rid of them? they are infesting my mother. One more question, if i take a clone off my mother, let it grow and take a clone off of it, does the quality get better or worse.

WEBMASTER:  ..in promix fungus gnats are not really a problem... in water tables they can be very damaging.... there is the specific stuff you can only get from homegrown hydroponics, called biovac or viobac..... or you can mix Neem Oil and soak the roots.... lower the temperatures down to 24C when doing that.....


Comments

i read somewhere that it is normal for some sun leaves to wilt a little during flowering, my question is is it better to cut them off or just leave them alone and also should i cut off big sunleaves that block light from lower branches or leave them alone?

WEBMASTER:  ..if a leaf is more then 50% damaged (or lacks the green color) then I could cut it... problem is that I DO want you to "pick" at her every day, a leaf here and a leaf there... if you do that kind of thing clean off the plants from dying leafs every couple of weeks, all at the same time but otherwise try to leave her alone :-) ....


Comments

hey mark thanks for the information about my license now i hear that if u leave our light out in the last part of flower the buds will form more of the crystal is this true or false

WEBMASTER:  ..yes. that is why some people turn off the lights for the last 3 days before chopping them down... personally I do not do that as I can not tell much of a difference.... some strains like wwxxx (I think as well as other white widow mixes) really responds to that but some do not ......

Hello Mark was lurkin around for a bit was wondering about sexing clones. I have had clones under the dome now for 4 days and i left the dome off for an hour and a few wilted a bit not much (keep spraying them often or keep the dome on for another 24 hours then remove it again) and they are fairly big clones like 4-5 inch would it be OK to sex them ANYWAY im thinking by the time they actually die ill get the info i need anyway :D YES? NO?

WEBMASTER:  ..if they are ok under the dome then keep the dome ON but start the bloom/sexing anyways... they don't need to be "perfect"... sort of as long as they live.....

Hey Mark. I forgot to ask u about a carbon filter i seen in one of ur pics but its just sitting on the floor hooked up to a fan in a corner of ur room I was wondering if this is as effective as it would be if it were hanging 8 feet above the plants. TYVM

WEBMASTER:  ..works either way however it would be better if it was hanging off of the ceiling as the hot air migrates to the top so it would get removed first.....


Comments

hey mark, I was wondering what the mixture of superthrive would be on top of my other nutes or should i give them Superthrive by itself mixed with water. TYVM

WEBMASTER:  ...superthrive is mainly B1 vitamin which is good when plants are young and starting to develop roots... you can use it throughout the entire veg cycle but not in bloom as it will stretch them.. which is not good in bloom...... you can not really overfeed with B1 so any dose is a good dose however its generally no more then 1 ml per gallon of water.... 2 me gallon is 4 liters....

Hello and Thanks for the Help in advanced. A little background. Growing Blueberry/Skunk and G13/Budda, 3 weeks since cloning (About 17-20cm tall). Using Pro-Mix in 1gal Grow Bags (Will transplant to 3gal bags soon). Using General Hydro Grow and Bloom one mix powder (Easy for a sick person to use). Using RO water because there is hard well water. Under 175w MH lights, they grew perfect at 1/2 strength nutes, every watering. Now the plants are under 1000w AgroSun MH (60-65cm above plants) and the G13/Budda plants lower leaves are starting to turn color. The veins first turned almost a copper color and then the leafs started to yellow. Only one Blueberry is showing the same problem. After moving plants from 175 MH to 1000 MH I have done one watering of 1/2 strength nutes and then 4 days later (Dry Pro-Mix) a watering of full strength nutes. The plants don't look like they are over feed but something isn't right. The Blueberries are a nice dark green color and the G13 are a little lighter in color but no burnt tips or curled leafs. What should I watch for so I know what to do next watering. Second Question - Should I transplant from the 1gal bags to 3gal bags before moving into flowering?

WEBMASTER:  ...with a 1000W I could mix in nutrients at full strength every watering cycle for 3 consecutive cycles at least.... so my instinct says that the G13 should be continued fed at 100% and/or more by may be 20% ... yellowing does have the tendency to come from underfeeding since (given no burnt tips and such) the 1000W is providing plants with lots of opportunities to grow faster then they could under a 175W.... mix in 25% more nutrients and give it to one plant ..... see in 24 hours if there is a difference..... you can transplant at the same time as you go into bloom and I think you should have done this earlier by a week.... but even with on set of bloom the plants grow/veg for 2 weeks still so a transplanted plant has a lot of time to adjust.....

hey mark, im 2 weeks in bloom stage, and my question is, is it too late to clone from female plants and when is the latest time or stage to clone? ( just finished identifying all males). thanks!

WEBMASTER:  ...technically its ok to take clones 2 weeks into bloom but they will take a longer time to root... 3 weeks ..... you can always take some smaller bottom branches that would be trimmed off anyways and try ....

Hey their, very new to hydroponics, looking from where to get seeds, "homemade" but successful solutions and a book recommended would be appreciated. I have a terminal illness and in early 50's and pot is the only thing helps with my discomfort if someone wants to put me in jail for that, than something is really wrong with this world. Marc

WEBMASTER:  ...get seeds here.... read on line guide here to grow your own easily.... and get equipment here .... if you like books The Marihuana Bible by Cervantes is pretty easy to read.... when it comes to medical issues read about me here and about how to get yourself legal...... but there is something wrong in the world... stay safe :-) ... and always feel free to post questions here...

What are suckers on tomato plants and how and when does a person remove them?

WEBMASTER:  .....I got this from another forum...."Question: Should tomato plants be suckered at the first sight of blooms? If so, why and how is this done? A: Pruning is the selective removal of "suckers", those side shoots that grow from the crotch above a leaf branch. If these are not removed, each sucker will become a main stem with flowers, fruit and even more suckers. By pruning tomatoes, you are reducing some of the potential fruit the plant could produce. Rather than a plant producing 80 fruit, a pruned plant may produce only 40. Since there are fewer fruit each will weigh more. This doesn't mean that a cherry sized fruit will turn into a giant beefsteak type but it will typically add an ounce or two, depending on the level of pruning"  ......  same as for cannabis.... but replace the word sucker for branch... those branches that have no access to light (too far or too low or behind another branch) and should be cut off so the other branches can yield more....

When using the peroxide, alcohol, dish soap method for mites is it required to raise the lights as it is when using NEEM OIL. TYVM N TC

WEBMASTER:  ......not really, if you have good ventilation and temperatures around 80F or 27C you do not have to.... with Neem Oil you must...

hey mark i wanna try growing outdoors this year i wanna put my seedlings up north this weekend would that be ok or is it still to cold

WEBMASTER:  ......daily temperatures are ok but at night it drops too low... I would wait until either late April or early May.... if you could keep them indoors for the night it would be ok.....

mark i live in a hundred year old farm house and was planning on building a room in the basement. Now only a small portion of the basement is concrete and that is where i want to build my room. On the weekend i had guest so i put my plants in the basement which i ordered from you and all sported and looking beautiful. My problem is i noticed lots of fungus nats. I had this problem once using cubes and they sucked the life out of my plants it was a real disaster. I am now using soil and i heard that they don't feed off the roots in soil something i find hard to believe. For now i have moved them out of the basement and i plane to treat them tomorrow as a precaution. My question to you is do you think i should abandon the basement idea are do you think once i seal the room will i be able to control them are have you ever heard of any bug bomb i could let of in the basement to wipe them out. Once again thanks and i look forward to your input.

WEBMASTER:  .......I personally have zero problems with root type of insects and the only problem when using promix type of soil is mites.... I never found fungus gnats a problem... but if you want to control the gnats mix Neem oil into the next 2 watering cycles.... with a basement like that I would double the CFM outtake fan power necessary... so for example if you have a 400W and the CFM (CFM is a rating of fans, stands for Cubic Feet per Minute) needed for ventilation is somewhere around 80 CFM get 200 CFM if you have a 1000W you need 150 CFM Fan so get 300 CFM... when you take this much fan power in a basement you can actually kill mold... since mold lives in stale air, but with this much power there would be no stale air, in fact mold dies off if expose to constantly rushing air..... I just assume that basements tend to be humid.. but ventilated properly can be a really good thing....

Hey Mark, Well I'm getting antsy im going to bloom my babies in the next 2-3 days they been in veg for almost 6 weeks from seed, I was wondering if it was OK to use ur spider MITE formula (THE ONE IN YOUR GROW GUIDE) as a pre treatment before i went into bloom. I do not have mites now just as a precaution. TYVM all info is much appreciated

WEBMASTER:  ...yes and of course.. mites are always there.. you just keep them under control... in veg I support use of pesticides if you want... not in bloom.. spray once and then repeat in 3 days....


Comments

how important is it to keep the veg room (18on/6off) in complete darkness (not at all, in fact you can keep the light ON for 24 hours)... the room is not light tight some light seeps in from natural source (this natural source could actually be better than the bulb so you may want to explore it) and other light bulbs is this ok ?? (yes in veg, NOT in bloom, in bloom this will stop your blooming process cold).... bloom room is super light tight no light leaks whatsoever... would i get more vigorous growth results if veg room is light tight ? everything else is up to par according to grow guide

WEBMASTER:  ..in veg I keep my lights ON for 24 hours a day.. I find the plants like it ..... the only concern may be power usage...

Hows it goin Mark, I have ur skunk 69 feminized, But i often hear you talkin about they make HORRIBLE MOTHER PLANTS. Can u please give me some examples on how it will be horrible cause i was gunna try it anyway and just to see what happens. Would the bud be the same, taste, yield, ect TYVM N TC

WEBMASTER:  ..by horrible I mean that there is a easier possibility of the clones reverting to hermaphrodites when put through a stressful environment.... at worst you will have seeds in your bud..... now many seeds usually depends on how well you control your temperatures... if your temperature stays at 30C and above, it is particularly stressful to these type of feminized varieties.... so for a mother plant I would rather keep a so called pure breed ..... its easier to take care and does not get affected by stress as much .....

Hey Mark, I noticed u talking about WHITE SHARK, <is this plant 99% Indica if so do u have any seeds for sale for that particular strain say it is used for Pain ??TYVM N TC

WEBMASTER:  ..with in the next 3 months I will rebreed this strain... at least 3 months.... it is a good strain and its more like 90% indica....


Comments

hey bud, how are u today, wondering about your opinion on grow bags opposed to pots. thanx and god bless

WEBMASTER:  ..Thumps UP, easier to carry and easier to conceal ... but can be a bit more bitchy when watering.. since the pots have more rigid structure so water spillage happens less with pots....


Comments

Hows it goin Mark? Well the clones have seem to be doing a lot better all but one seem to be doing fine, and the one that is not its only a lower leave that has yellowed a bit is this normal? I have them 1 inch from 2 40w growlux floros for the past 3 days and lights on 24 hrs with a dome and i have been spraying 4 times a day MAX. So now what am i looking for in plant behavior before i switch these clones to 12/12.Or should they be a custom to their new surroundings now? TYVM

WEBMASTER:  ..mix some nutrients next time you water them, veg food, but make sure its something like 1/10 of normal dosage..... but (i think) give them a day or two and change the cycle back to 12/12... sex should appear after 10 day or so....

I have a packet of BioTLC ( the size of a fast food ketchup one) of Liquid Growth. 6-12-6. It mixes with 1 gallon of water....Sound Ok? and ... is it safe to mix up all at once and keep in a container and then how should i use that mix?......25%mixture + 75% pure water or the Mixture alone....or should I throw it out considering the size and sketchiness and buy me a big bucket of nutrients.?

WEBMASTER:  .....you want a proper nutrient with a clear label from a hydroponics store ... yours seems like a bud booster from this number 6-12-6.... you could use it when blooming but for the veg period this is not good.....

I have 3 sweet purple plants, they've been growing for 1 month, give or take a few days. Im growing under 3, 15 W fluorescents,, they are growing their 6th set of leaves + the mini leaves starting to grow in between the stems.... its growing nice&full, but they are only about 15 cm tall. Should I only expect a 1-2 ft tall plant after a month using a HPS light , not florescent..? Would fluorescents (I really cant spell that word and i know i cant so im very sorry) be efficient for growing 3 + plants...Assuming the lights are a high wattage?. One problem I saw was a browning on the tips of the plants when they were younger, and now a yellowy brown spotting / spoltching that happens randomly in the middle of the leaf, Its not mites- Is it a Nutrient deficiency? (I would decrease the nutrient level significantly since they do not have enough light to process the nutrients)

WEBMASTER:  ..the problem is that with 3 x 15W fluorescent lights, its not very much power... so your you should stay at may be 20% of recommended nutrient dosage .... to be honest I would never ever bloom with fluorescent lights unless you get into 400W of total power... that is why its easier to just get one bulb at 250W or 400W from a HID type of a light (either MH or HPS) so ...... you would have to have a stack of fluorescent bulbs to equal the wattage (W) of an HID light but you can not equal the lumens.... so in the end the yield from a fluorescent garden always disappoints....

hey there i am in the process of applying for my license and is our approval base on Ottawa or our medical doctors can Ottawa rejected the app. base on there decision on where u need it or not?

WEBMASTER:  ..no they can not, this is a court mandated program so, as long as your doctor signed the forms (and they are correctly done) Health Canada can not dispute it.... they can delay it because of some technicality so make sure the forms get filled out correctly and legibly... also after mailing it to Health Canada call them after 4 weeks and ask if everything is ok with your forms... they may tell you your picture is blurry or some page is missing a signature .... fix it and with in another 4 weeks you should get the permit....

I've got 5 WW-Bhudda which I've germinated (2 days) and are now being vegged for the last 7 days under a 250 watt MH in a deep water culture system using DNF. They are now 4 inches tall and are developing their 3rd set of leaves. Is it to soon to switch them over to Bloom using a 430 watt sodium? I've added some support for them as they are growing pretty fast (using DNF grow at 1.4 mil per litre) and my fan is gently waffting them in a slight breeze.

WEBMASTER:  ..it is never too soon to switch them to bloom... as long as you remember that given that you have 250W they should double in height and may be even triple...

Hey Mark, I've been having trouble to find the right food plant. Where can I get it? Also, I only found Pro-mix seeding and potting mix (no good sorry, ask them for a professional triple mix.. they should show you big bails of whatever triple mix them have). I didn't find the Pro-mix BX or Pro-mix HP, so I planted the sprouts in the other one I found. Is that o.k? Thank you for your help.

WEBMASTER:  ..the plants will be ok when small but as soon as they reach few inches they will have the problem with this type of soil.... I would re-pot them in to the proper triple-mix when you find it.... keep in mind that its not like they will die or something but .... the plants won't reach their full potential....

Hey Mark i was also wondering where the new growth will start after i supercropped? Would it be directly where i cut the tops off or will it be below the cut? (I am not sure what to look for) I have went ahead and took ur advice and chopped them all down to like 1 foot and a foot and a half give or take an inch or 2.i wish i would have done this within the first 2 weeks of veg (but u live and learn first timer neway LOL)ALL UR INFFO ON SUPERCROPPING IS MUCH APPRECIATED and i feel this will be the best result for me as i am using 2 400w setup and is recommended for 400w users to supercrop NO? YES? How much of a difference in yield wise will supercropping promote? TYVM N TC HAGD

WEBMASTER:  ..to me super cropping is just one of many ways of growing .... for you it works, to other it may not....it depends on the number of plants ina space....5 plants in a 4 x 4 space need to be cropped, but 10 plants need not as long as you veg them less..... after the cut it takes plants a week to start re-growing... but after I would expect an inch a day of growth....


Comments

Well Mark…. I am about 4 weeks after starting from seeds. The plants were doing pretty well until after I gave nutes twice. Using Pure Blend Pro I used only about 4ml/gal…. 3 days apart. After that I leeched them because of the necrotic spotting and yellowing around the spotting. Leeching seemed to help slow down the damage but still didn’t seem to do the trick. I then checked my Ph level and it was a little above 7 and I am growing in Pro-Mix (BX or HP?). So I flushed out all my plants again with a Ph of 6 added some superthrive to the last watering and things seem to be doing better…. Not noticing any new spots really and the new growths are uniform not retarded looking like they were for a few sets of leaves. I am not totally sure if I have solve my problem or not…

WEBMASTER:  ..what kind of lights do you have? sounds like fluorescent?


Comments

Hi Mark - Ref: April 11 post. I never got a chance to water one of the seeds that didn't open of course but the one tap root I planted that didn't grow (and all the rest actually) were given 25% strength flora nova 7-4-10. (much too high.. it should be just a trace amounts ... like 1 to 5% maybe, and I do not use any when popping the seeds) The other 3 after 1 month are growing so very nice. 1 of them is only 7 inches tall and 15 inches across. Wow! Bushville. As always Thx for your help man. Be well.....OGG

WEBMASTER:  ..BTW flora nova just came up with a revised dosage for its product ... you should probably double check with their website....

I was reading along, when I read that you can get free seeds with MMAR card, is this true and what kinds are they giving way. Thanks again Mark I don't know where get the time for all these questions, you are a good man.

WEBMASTER:  ...with a MMAR card you can get clones ..... email me a copy of your card and pick 10 seeds of Toronto420 kind and contact me....

Hi Mr. Mark how are you today. I was just wondering about clipping the tops to make the plants bush out. I know to do it at the 4th or 5th internode. How long after would you take the tops off again, (once a week) and how many times for a 5 foot plant. I seem to have lots of small branches that are leggy on some plants, can I cut them off at 5 days in flower, or try to tie them up. (try to tie up first but if they still get no light cut them) Thanks again. I hope the guy that got beat up for smoking his medicine gets a speedy recovery, and the guy that did it goes to jail.

WEBMASTER:  ...5 foot tall plant should provide me 50 clones once a week..... in veg feel free to make cutting once a week..... in bloom you can take cutting up to 2 weeks in to bloom but not after.... feel free to prune the lower branches even 3 weeks into bloom... if the branch does not get any light it should be cut... its a drain on the rest of the plant.... read this page... instead of "prunning" take clones...


Comments

What does it mean when the bottom leaves starting showing brown spots between viens on the leaves? These brown spots started spreading to leaves above and eventually some of the bottom leaves were just completely covered with yellow and brown and were crunchy?

WEBMASTER:  ....it looks like an issue with nutrition.... (just off the top of my head) over watering .. watering too often combined with overfeeding.... I would say that you have to make sure that when watering they get a complete soak and then you wait for the medium to dry out completely... should take 2 days minimum and longer.... In this case I would leach out the nutrients for a few days and provide a fresh full batch of nutrients.... are they in veg or bloom???? 


Comments

when i top my plants can i use the topped part as a clone and make a mother out of it or another plant to put into bloom (yes)... meaning when i top the plant i cut the MAIN stem in order to get it bushy (when you remove the top the growth? hormones transfer to the other smaller stems below and the plants produce more side branches thus making it bush out) .. will this work ??

WEBMASTER:  .of course it will work... this is how you collect clones... before topping the plant you remove any usable clones and then cut what needs to be cut off of the mother plant..... the more "toppings" you make the more bushy the plant becomes.. do not top more then twice as the plants will actually yield smaller buds and its just not worth it....

hey mark how are u, mmar cardholder with hash plants, wondering about curing, is this mainly storing in dry airtight places ''aging' (pretty mush yes). they were sick with mites but think i have it under control with bang. can this product be used in bloom if needed when the time comes. thanx, enjoy the sun and hope to see u at the march.

WEBMASTER:  ....if you do not take care of mites by week 4 of bloom the only thing that you can spray your plants with is ice cold water ... spray throughout every couple of days..... bang is ok but it will change the original flavour of the bud... good news its not toxic.... so you can spray until the 3rd day before harvest..... when curing it means that you allowed the bud to dry completely (slowly over 1 week) and then you place it in an air tight container at room temperature in the dark... I prefer to cure in the fridge, which takes longer but tastes better....

Hi Mark Glad your back. 1 was lost all week, you are vary knowledgeable in growing. I've been growing since 1987 and I've only seen large hard heavy buds a few times. I have never used bud boosters or Cal Max or anything extra. Now that I can do things legally because of foot disease. I am now using bud boosters and some cal max. The only thing booster instructions say to use it at the 3rd week of flower, till the last week. Can you help me make hard rock buds because I have been growing for quite a while and I deserve, a BREAK. I wish I had talked to you earlier in my life. You are very smart. All I need to know is when to add the boosters. What do you look for, they say when first showing Pistils, Lot of white hairs, or when they start to zoom around the fifth week, or quick flowering and filling out. Please help me make rock hard buds. I am using hydroponics pots 12" 1 meshed pot in another pot leaving a 2" to 3 " space between them, similar to ebb and flow floods then drains back within 20 minutes. I feed them 4 times a day during light cycle only. Using 3, 1000 warm deluxe for lighting (replace bulbs every 4th cycle) , with shields,  co2 injection using bottled c02, DNF Flowering formula, 8 1/2' x 10' room. KOOL BLOOM, and DNF fortifier for bud boosters. They say weed is ready when most of the pistils turn brown, or is it when TRICHROMES turn opaque or darker (this is the most reliable if not difficult method). I hope I am not bothering you too much as I should know after 20 F--ing years. I guess my social phobia prevented me from talking to other people. Hope you have had a good day. Thanks alot.

WEBMASTER:  ..when harvesting I count the weeks... 90% of my plants finish at end of week 8, even if hairs are not all dark but the trichomes are opaque I harvest..... . the "secret" if you call it a secret.. is that I massively overfeed the plants staring in week 4 of bloom.. steady feed through week 1 and 3 and slowly rising till it culminates with 50% more nutrients then recommended (be careful because overfeeding is easy in a system like yours, promix is more forgiving)... in your case you have to drop your PH to 5.2 in week 4 to 6 .. at this point the plants can consume large amounts of bud boosters.... you can add bud boosters all the time at low dosages or twice in this 4 to 6 week cycle at very high dosages, usually this is measured ON TOP of your regular nutrient level... again be very careful... you have to watch your plants and it all really depends on how well the plants absorb the nutrients.. its a question of observing them and a bit of experience... .................................................................I still feel like I am in a closet and we are all hiding.... I wish it was a legal....

Hey Mark i just sent u some pics from progolfer1 named pics/wilting clones. It is now 2;13 Wednesday April 25th.All ur expertise is well appreciated and if it wasnt for u i prolly wouldn't have made it this far LOL TYVM

WEBMASTER:  ..your problem may have been the fact that I keep the lights ON for 24 hours for the first few days so the clones get used to the new environment.. once they set in I change the light to 12/12... I also keep the clones an inch away from the fluorescent lights....


Comments

Hey Mark, I asked you earlier if I could grow weed just regularly in my room and you said that for the vegetation period that should be o.k, but after the June solstice the plants should start budding but household light will confuse them. You then suggested putting a garbage bag over their heads for 12 hours for 2 months. So is it for two months AFTER the June solstice, when the plants switch into the blooming period or should I put a garbage bag over them before that as well, and if yes for how long? Another question, my seeds cracked about 6 days ago since then the sprouts have been getting bigger. I'm not going to be able to plant them until tomorrow evening, because that's when I'll get the supplies, so is there anything I should do to help them stay alive for the time being? I'm keeping them in my closet in wet toilet paper. Thank you for your help so much. I really want this to work. (a day or two may not make much of a difference so just keep it wet)

WEBMASTER:  ..the moment you switch their cycle to 12 ON and 12 OFF (by the garbage bag "method") the plants start budding and it takes 2 months to finish.... it is entirely up to you when you start this 12/12 cycle.... since the plants live on your schedule and I am sure your lights are ON for longer then 12 hours a day, they will not feel/see the solstice, so in your case it is a arbitrary date.... essentially when the plants reach 1 or 2 feet (up to you) start the budding by religiously placing the bag over their head for 12 hours EVERY SINGLE day for the next 2 months.....

hi ya mark thanx for the reply and yes i was keeping the dome on them for the full week waiting for them to grow. the dome is now off and hopefully everything will turn out right. I really appreciate the help this is a first time for me and it is quite a learning curve. But i must say your grow guide is an excellent place to start for newbies and this public forum is a great place to lessen that learning curve. thanks again for your help and i will probably be posting again soon :)

WEBMASTER:  ..spray them often for the first few days .... they may wilt for a while but if you put the dome back on take it off again once they come back to life..... this is how you "train" then to adjust to outside temperatures.....


Comments

Hey Mark sorry so many posts (first grow) i took clones from my plants today as u suggested but they do not seem healthy, very weak like and not all of them stand up in the rockwool is this normal will the strengthen up in a few days? or should i clip new ones? All ur help is much appreciated TY n TC

WEBMASTER:  ..how far away from lights?... is the dome ON?...


Comments

mark you are the man. quick question for you. my friend has a 7 by 8 by 7 foot tall room with 190 cfm exhaust fan. because it is summer what do you think he should run for lights. two for hundreds MH are one one thousand MH of coarse they will be in dirt. what do you recommend for lights and how many plants do you think would be optimum for this area. of coarse in winter i told him i would use two one thousands. but in the summer i think that would cause to many problems with mites and of course heat build up. keep up the good work cause you are the man and a man of your word. i would and will recommend you to anybody i know. so far everything has turned out one hundred percent. my friend has gotten 14 out of 15 seeds sprouted. and i will keep you up to date as she goes.

WEBMASTER:  ..190 CFM fan can handle 2 x 1000W in the autumn/winter/spring season but only 1 single 1000W in the summer..... I do 5 plants per 1000W vegged for 3 weeks from clones (seeds take longer).... in 12 inch pots (5 gallons volume)..... Thank You :-)


Comments

mark...did you say a couple months ago that a plant in veg (18hr) that starts to show as male MIGHT still turn out to be a female once the photoperiod is reduced to 12hrs? or should it be discarded...fast pine, ideal growth conditions.

WEBMASTER:  ..you are correct... (In my opinion).. in veg you can tell if a plant is a female but you can NOT tell if it is a male.... BUT a female CAN turn into a male (stress usually) .. a male can NOT turn into a female..... the only way is to take a clone off of a plant and bloom this clone... in 2 weeks before it dies it can tell you its parents sex...


Comments

Hey Mark i was talkin to ya earlier on in the day but was wondering when sexing my plants should i use the dome for the clones and spray them or should i just put them in the rockwool as is in a tray. TYVM N TC

WEBMASTER:  ..put them into pre-soaked rockwool and place the dome ON them for the next 48 to 72 hours... take the dome OFF after and spray up to 4 times a day but not more....

hi mark, can i use a 125+watt cfl with my 250watt hid?? only got a wee wardrobe and tried 400watt but trouble with heat so went back too my 250(bummer),then had a eurika moment,or just too much skuff:)&thought with cfl it produces less heat but can it get used in conjunction with hid????,only other option is boot the old lady out&use her wardrobes.(only jokin hun*@*"@:-(...)cheers BROTHER..

WEBMASTER:  ..lol.... it is ok to use CFL with HID, keep the CFLs on the sides and the HID on the top.....

well my last set of clones were to darn wet and i ruined alot of them me bad but i am new and bound to make mistakes my question is should i dilute some no damp in my spray bottle for doing my babies while the are in there little greenhouse? I do use it when i start them just wondering if i should use it in my regular spraying?

WEBMASTER:  ..the clones should be out of the dome and under regular humidity after 3 days after taking them.... they only need 100% humidity for the first 2 days and after they should be ok in the open.... if you keep the dome continuously .. after a week the become weak and wilt.....  I would not use no damp .... I bet you keep the dome ON them longer then 1 week?....


Comments

Hey Mark hows it goin? well my plants are 4 weeks old this Saturday past and some are not a foot and half high, would it still be safe to clip a clone (yes) and sex the smaller ones this will allow an additional 3-20 day veg period for the others to catch and if the bigger ones get out of control i can always prune them if need be right? (correct)  I was also thinking of super cropping all 19 but is it safe to do so with the strains i am using BBxS, NLxB, WWxB, (no problem, go ahead) and ur very own skunk69 which is growing superb as we speak very strong plant as well. But the white widow X BUDDA being a sativa acts differently then my others is this normal? THNX ALOT N TC

WEBMASTER:  ...sativa should be slower to develop and generally prefer a lower dosage of nutrients... she is also more delicate and susceptible to any problems, overheating, under or over watering.. etc....


Comments

when do i know when to place the seeds into jiffies or rock wool with the paper towel method ?? and which has a better success rate jiffies or rock wool ??

WEBMASTER:  ...you should work with promix and try this first... in general I prefer the jiffies because they are very basic to work with... rockwool needs explaining and a bit of experience to deal with....

5bbxsk 5nlxsk 10mix plants are 3wks today. thanks for the extras most appreciated. every seed germinated no probs. under floros in 10oz. beer cups in schultz potting mix all i could get in a hurry.18 plants in a 22''x12'' tray. problem is the lower leaves are drying right out the tops are all good. watering when dry with low nutes. its pretty crowded in the tray. could this be the problem? (one problem that's for sure) should i clip the dead/dried out leaves. (when overcrowded, then YES)  I k.o.ed one of the nlxsk by dropping the water bottle on it but its rallied back with a weird lookin bulge on the stalk. tough plant.10inches smellin good already.

WEBMASTER:  ...fluorescent lights are good for 1 foot away from the light... so if the leafs are further then one foot away from the bulb they will go yellow and there is nothing you can do unless you want to place extra fluorescent lights on the sides of the plant..... feeding more will only affect the leafs that receive the light... so that would overfeed them.....

ive got couple seeds which im having a very hard time sprouting ... ak47 and white widow ... i only have 10 of each . and ive tried multiple ways to sprout .. placing them in water then once they first crack placing them in rock wool that soaked over night (failed) second was the paper towel method and waiting till i see about 1/4inch of root then placing them in rock wool that was soaked over night (failed) when all failed i just tried placing the seed into the soaked rock wool (this should work) as is (failed) what the hell am i doing wrong im starting to run out of very expensive seeds i don't understand ... all was either on a heating pad and used aerated tap water at the temp of 75 degrees

WEBMASTER:  ....if you use rockwool.. simple pre-soak the rockwool overnight and then place the (un-sprouted) seed right into the rockwool... and place in a dark place..... there is no need to sprout the seed and then placing it into the rockwool.... it only works like that with promix.... may be you should get promix.... relax I will give you some seeds if you fail completely...

I'm trying to grow weed in my room and I have a couple of questions. I found 3 weed seeds in some weed that I got once and kept them. Now I sprouted them and I'm planning to plant them. First question is whether or not you think these seeds (now sprouts) will yield good plants. Second question is whether or not I can grow it just regularly in my room rather than in a closet. I have a large south window and another small west window in my room. Therefore my room always gets lots of light. As well, my room is always very hot in the summer. I have other plants growing in my room and they are growing very well. Do you think weed plants would grow well and yield a reasonable crop? Thank You.

WEBMASTER:  ..they should be ok when it comes to the vegetating cycle but bloom would be a big problem.... at some point after June solstice the plants will start budding but if you live among the plants, your household lights will confuse them ... cannabis plants need 12 hours of complete darkness in order to bud (produce pot).... if they get get disturbed with lights when sleeping they will not produce anything.... one option would be to put a garbage bag over the plants head for 12 hours a day and make sure to do this religiously for 2 months......

hi mark; i have planted nine clones 8-10 inches in height under 600 watt, they look healthy but they have not grown in 5 days. am i doing something wrong? do you have any suggestions for me, i would really appreciate your feedback.

WEBMASTER:  ..it is not unusual for plant to take 7 days to recover from a shocking event... transplanting is a shocking event.... after 7 days they usually resume growing.....

Hi Guy how u duin. I was wondering if I should clip the centres on the hash plant and white widow crossed with budda, to make them bushier. I heard on some plants you shouldn't clip the centers. What is your opinion. I want the best yield that's possible. I always thought you get more by making them bush out. I don't think I ever had a plant that wasn't bushed out, so I don't even know what's better. Bet you do though. P.S can u make a list of the different clones you have. hey i'd like to come down and have a beer with you some day, plus buy the cellphone finder a few beer. Talk to you later Mark, thanx agane.

WEBMASTER:  ..clones are available for medical patients only.... usually with 2 weeks notice... I would cut all plants.. to make them bushier.... only some sativa dominant plants do not like being topped/cut... but even then I only met one plant that behaved like that so I would not worry... cut them all...

I recently moved to the house I am in now a little over 2 years ago. I was told by the neighbors that the previous owner grew pot here. For the past 2 summers (that I have been here) about a dozen plants have come up in the back garden that look very much like marijuana, well the leaves do at least since there is not much to the plants. They grow about 3 - 3 1/2 feet tall, are extremely skinny and have small yellow flowers. They also have leaves (as mentioned) that look exactly like marijuana leaves to me. There are (I believe) 7 leaves at the end of the branches shaped like marijuana plant leaves. Is it possible that these plants are marijuana? They seem to grow for 2 or 3 months then die off when the flowering is done. I really haven't paid as much attention to them as I should because I just couldn't believe that pot would come up year after year. What do you think? I don't have any pics unfortunately. If they ARE pot, my guess is that they just don't grow properly in the conditions and location they are at. They sure look like very poor pot plants to me but I'm not an expert either. I tried to find another plant online with leaves like a marijuana plant but couldn't. Is it possible that these are marijuana plants? If not, what on earth has leaves like a pot plant? I'm really curious about this. Thanks so much.

WEBMASTER:  ..they are probably pot... they can be so called ditch weed... still cannabis though..... the plants drop the seeds every September which then hibernate throughout the winter and re-grow in the sprig..... If you take care of them, i.e. feed the with nutrients they could be some good stone.... I would suggest you send me a picture once something pops out of the ground... they could just be real weeds... there is one particular species that looks like cannabis but its not....

Hey Marek U haven't been around in a while hope everything is OK. (its all good) well i now have got some cash together for a good ventilation system somewhere between 400-450$. I have a total of 800w HPS Hortilux in a room 6by5 i was wondering if 175cfm fan with a 200cfm carbon filter would be sufficient? or should the cfm rating of the fan exceed the cfm rating of the carbon filter? Should this type of ventilation cure smell to 100% if vented out a window? (yes) also was wondering if any plain ole joe can buy equipment from HAPPYGIRL or do u have to be a cardholder THNX N TC (sorry cardholders only)

WEBMASTER:  ..I would try to match the power of the fan and the filter, get a fan rated at 200+ CFM.... remember that you lose 50 CFM of power if your ventilation hose is longer then 10 feet... OR if you have a 90 degree kink anywhere along the ventilation line..... therefore if you have 200+ CFM fan and 200 CFM filter and you lose 50 CFM anywhere ... at 150 CFM you still theoretically have enough power to ventilate a 1000W bulb... and you have 800W.. so you should be good...:-) shop here in Toronto.. they know thier s#&t.....

Hi Mark How's it going. What is this about health Canada scrapping the licenses for personal use and production license. Does this mean I have to buy there crap. I'm losing sleep over this bullshit. How the heck can they do this. I think once you get your license, it should be good for life and I'm going to make it good for life. I will grow whether they like it or not. I've been in jail before. What is there problem. bunch of Idiots.

WEBMASTER:  ..unfortunately the license is good for one year... there is a case going through Ontario Courts right now... Parker is challenging the crown about this very issue.... the way stuff works in Canada this case will redefine what is and is not allowed..... even the Feds can not change this.... but the bottom line it is a complete waste of time and utter bullshit... sick people are deprived of medicine because ???.... why??? .....

Hi Mark How are you today. Remember I had a major problem with spider mites. Well I went and talked to a friend of mine about getting rid of these damn mites, and he handed me a 250 ml bottle of liquid and said spray 1 part water to 1 part organic liquid spray, then the second time in about 3 days. He said it is totally organic. So I went home and checked for mites and low and behold the plants are loaded with these damned mites, so I mixed up the liquid and instead of spraying, I dunked them upside down in the liquid. the next day I got my 18x Magnifier and started looking underneath the leaf for the mites, well what do you know, I only seen a very few. I dunked them the second time after three days, and looked the next day and could not find any alive. All the eggs and mites had a orange appearance to them but they were all dead. I think my friend has a gold mine with this stuff. It really works. Thanks again Mark.

WEBMASTER:  ..dunking works.... :-)

Hi Mark. I'm gonna go out up north soon with my ladies and was wondering if I should water them before the journey or leave them dry? I'm using large styrophone cups and I'm putting another cup reversing it to close the plant off and be safe in there. That I tape so it don't open in my bag. I'm doing 15 like that so hopefully I get something out of it at the end. What is the best way to transport small planted clones? How do the pros do it when they do crazy amounts? they must camp in the wild eh?? The journey will probably be 8h for me, and they'll have to wait another 12 or so more before the morning and the long hike to put them in ground. I'm gonna plant them by a stream or something like that and hope f&%#$ animals don't wanna munch on them and get stoned. The roots are well developed so if I plant hem correctly by a stream,(15) how much should I get out of that? Toke you! :)

WEBMASTER:  ..there is not secrets... logistics... car, big truck, definitely water them before you go.....low dosage of nutrients....

We are nearly 30 days into the vegetation stage but the plants are still not 1.5 feet tall. Should we bloom or wait? Thanks

WEBMASTER:  ..if they are 1 foot at least I would start blooming.....

Hey Marek, I have a plant that droops his leaves around 1 hour or so before lights go off every night, i was wondering what causes this or is it even anything to worry about they seem to perk back up but is this slowing the growth cycle for this plant. Also thnx for ur expertise in regards to my pics as i am glad to hear that there is no emergency. They seem to be doing really well now as they are 3 weeks old april 14. TYVM N TC

WEBMASTER:  ..check if she needs a bit more water then the rest of the plants... but may be this is normal for this plant...

I am interested in purchasing a 1000 watt bulb for my woman when i need to change the cycle, i was just wondering if you had some comment/suggestions, etc... about the bulb. I'm pretty much looking at the difference in hydro and the quantity that i can produce...Thanks for the help.

WEBMASTER:  ..in short.... I go for the cheap bulbs in general, but I replace them after 8 months, however there is SunMaster Warm Deluxe for the MH spectrum and the Hotrilux 1000W for the HPS spectrum.... these bulbs are 30% better but are also expensive.....

Hello again Sir; How art thou? Well, I finally had the time and space to begin my skunk 69 (project #2 only for me). I am going note for note as per your grow guide. Promix BX, 400 watt HID (4 feet away first week) etc... Day 1 I began germ. phaze. 4 of the 5 pack cracked a tap root within less than 24 hrs. (WOW) I placed the 4 new taps into their respective pots of promix. 3 of the 4 are developing nicely. The 4th one refused to show itself. Its been a week and a half now so Im guessing one of the taps must have lost its vigor from towel to potting. The 5th seed didn't bother to germinate in the paper towel. I am at a loss. I feel as though I've been too a funeral. 2 of my girls have died. Please help...............................

WEBMASTER:  .....please elaborate as to how you watered them and what kind of nutrients etc.....

or is this a better floro bulb Sylvania 48" T12 Cool White Cold Temp Fluorescent Tube T12 Shape Recessed double contact base Initial lumens 4050 Nominal wattage 60 12,000 hours of life 62 CRI; 4200 Color temperature

WEBMASTER:  ..I have never tried these so I can not say... but the specification definitely seem better then the one I use myself.... I would say go ahead with any of these... get one of each...


Comments

are 48" t12 3,000 lumen Sylvania cool white plus fluorescent tubes sufficient for mother plants ? 2 fixtures with 2 bulbs a piece.... (I grow with these)

WEBMASTER:  ....yes, however you have to keep your plants to no more then 1 foot in height... this is from a post below that...."fluorescent lights are good for 1 foot away from the light... so if the leafs are further then one foot away from the bulb they will go yellow and there is nothing you can do unless you want to place extra fluorescent lights on the sides of the plant..... feeding more will only affect the leafs that receive the light... so you are correct that would overfeed them..... extra light is the only answers BUT if they are meant to be mother plants I would be cutting them down so they stay around 1 foot in height..... "

Thanks for answering my other questions. I'm currently using a 150W MH to veg 3 plants. I want to go to 400W. Would HPS be my best choice since I already have the 150W MH setup (yes, exactly) that I can use for clones and vegetating? That brings another question ... having both setups... Would you use the 400W HPS for the entire grow or use the 150W for the veg cycle and switch to the HPS when I change to the bloom cycle?

WEBMASTER:  .... I would use both at the same time.. more power, better yields.... however if you are restricted on space... I would use the 150W for the veg and 400W for the bloom...


Comments

hi again, also would it be a good idea to prune these dying yellow leaves off? They are pretty bad. Thanks again.

WEBMASTER:  ....only when there is NO green colour what-so-ever.... and generally I don't like picking leafs off unless you do it when you take clones... BTW.. you should take clones immediately.... cut her down to half her size....

hello, I'm having a problem with my bottom leaves yellowing. My plants are in veg and I'm using a one part organic fertilizer along with an organic B vitamin supplement. Also they are under fluorescent lights. I started off with lighter nutes then what was called for and have been increasing it now to the full dosage but the yellowing continues. I don't really want to over fertilize them, so should I increase the nutes or not or is there another problem I should be worrying about. These plants are intended to be mothers. Also they are in promix and I still ph the water. Any advice to make my lovely ladies lush and green again would be greatly appreciated. Thanks alot. Also they are about 3 weeks old.

WEBMASTER:  ....this is a classic problem of lack of light... fluorescent lights are good for 1 foot away from the light... so if the leafs are further then one foot away from the bulb they will go yellow and there is nothing you can do unless you want to place extra fluorescent lights on the sides of the plant..... feeding more will only affect the leafs that receive the light... so you are correct that would overfeed them..... extra light is the only answers BUT if they are meant to be mother plants I would be cutting them down so they stay around 1 foot in height.....

Marek, Grandma's 80 years old suffers from extreme arthritis takes lots of pain killers, she wants to give pot a try so she doesn't have to live her last days in pain, could we get her a medical card to grow and possess and do you have a good indica strain available or something that would be ideal for her arthritis

WEBMASTER:  ....she would have to get the permit herself and designate your location as a grow area.... in other words you can grow for her but you can not identify yourself as the grower... in theory her place would be .. where she stores the weed and your place would be where she grows it.... I have white shark a strong indica which takes the pain away.....

Hey Marek, I have sent a few pics (april 10 7pm) all pics of plants are about 2 weeks and 3 days old from ur seeds (of course) the E mail they came from is progolfer1.also the subject is NUTE BURN. also was wondering when the appropriate time would be to sex my plants. also to sex the plants would it have to be complete darkness at the 12/12 cycle as i do understand about turning hermie but does this still apply as the plants will be still young? AS always all help is greatly appreciated. TY N TC :D

WEBMASTER:  ....I saw the pictures and there is no problem... a nutrient burn would be a far more visible problem... they look like small plants with nice heavy green colour... you may be pushing their feeding regiment but they do not like in any way burnt.... decrease the nutrients by half but there is no emergency.. in order to find sex, you have to clip a small clone off of each plant and set those clones to bloom immediately without waiting for them to root... you need any light (i mean incandescent bulb would probably do) and any space (like a kitchen cupboard)... by the time they'll die, they will show sex..... from your pictures I can see that you may want to have to wait a week before you clone them.... I would take the biggest top branch as the initial clone.... this would makes the entire plant bushier....

hey bud one more quick one, temp. in room is about 70-75 in the day, at night don't know i don't go in there and i am in 5-6 week in bloom is this ok. thanks

WEBMASTER:  ..you are lucky to have low temperatures... because most people complain about temperatures being too high.... the problem is that your plants will not be able to consume as many nutrients and grow as fast as they could if they had 78 to 82 F.... this is the best temperature for cannabis.... in your case the yield will be a bit less then it should.... but in no way is this unhealthy... just would be better if it was a bit higher....


Comments

hi mark I got your G13x buddah and it's flourishing greatly, Thanks! But my question is about PK13/14. I heard the yield is good but the smoke quality is compromised. (NOT TRUE) Now i'm looking for a head high but I don't like to be growing continuously. What product may I use for good yield without compromise to taste flavour potency etc. what have you heard about superthrive? (use ONLY IN VEG, in bloom super thrive will STRETCH your plants, which is not good) Thanks again, you are a weed god :D

WEBMASTER:  ..I use both, super thrive in veg and PK-13-14 in the 4th to the 6th week of bloom..... PK-13-14 is nothing special and it does not contain any "secrets", ... just another rumor....


Comments

hi mark, after planting the small plants into bigger pots, one of the plants has started drooping it's leaves. The color is fine and otherwise it looks healthy but i recall reading somewhere in your grow guide that drooping leaves means the plant is unhealthy. What are some possible explanations and remedies? I don't want the plant to die.

WEBMASTER:  ..transplant is a very stressful experience, but I bet you the plant has recovered by the time I reply to your message... They often drop their leafs a bit after transplant but they usually re-bound after 24 hours or so..... its not a sign of unhealthy plant... its more of a effect of transplanting...


Comments

hey mark, fine day for indoor cart racing, but i have a question for u . wondering if i can determine sex a of a plant using a fluorescent light? just in case one day when i need little ladies and can't get them. i am a mmar for poss. cardholder and we have met.

WEBMASTER:  ..MMAR card holder should call me direct 416-824-5156... and yes you can use fluorescent light to sex plants..... any light really.... its only for blooming that you need HID lights.....

Hi Mark, I'm wondering if my clones will bounce back. I have a few clones that I haven't put in promix yet, I left them in their rockwool for a bit longer then I should have, all the roots have turned yellowish color and aren't that vigorous anymore. I think it might be root rot. Would they bounce back in promix? thank you.

WEBMASTER:  ....transplant immediately and most should re-grow... brown roots means they have been exposed to light .... most roots will re-grow and most plants should re-bound....


Comments

Hey Marek i have a nute prob i think with 3 or 4 plants max, but it isn't that bad i don't think. They have a few burnt spots at first i thought it might have been heat stress but i moved the lights higher and it is continuing on the new growth so i flushed with 10%nutes.example the leaves have dry burnt patches on spots here n there. would inconsistently adding water/nute mix cause this problem? all help is much appreciated. Also the NLxB i got from u all seem to be stunted very slow and SMALL NE suggestions. Using promix, pure blend pro vegatative, 2 times 400w eye Hortilux bulbs.

WEBMASTER:  ..inconsistent waterings and nutrients would make it very difficult to recognize a problem... but if I had this problem with this many plants I would be blaming overfeeding, continue with low level nutrinets.... I would also look into how often you water them and how much.... I notice that people give the plants water too often... allow them to dry out before watering again.....


Comments

How many ounces will you need to get 400ppm? Using 20-20-20 for a 5 gallon stock tank.

WEBMASTER:  ....you should not be using ounces as your measurement.... I would add NO MORE then 1 ml per 1 liter of tap water.... so to archive 400ppm you would have to add 0.001 ml/L since normal water testes at 300ppm...


Comments

Sorry Mark I did't know pentax was a pesticide, somebody talked about it and said it killed the spiders and eggs not humans (haha) I'll stick with the stuff you talked about. Hey bud just 1 more question, is it advisable to run straight water or RO for the last 3 or 4 days before harvest to improve on flavour, (yes) besides reducing nutrients in the last 2 weeks. Thanks again Mark you've been a great help. PS can I call you DOC. HAHA, maybe see you on the 4th. of May.

WEBMASTER:  ...EVERYONE should come......


Comments

Getting back after putting the girls in bloom. I've got 2 weeks left and I see you've changed your data a bit. What I was going to do was put about 10% nutes per bucket until completely coming out of the bottom of the pails and get rid of the old nutes. Doing this for the last 2 weeks. Would this be correct? (yes) I've read were you just keep on dumping clean water until all is clean.

WEBMASTER:  ...I revised my guide and now I prefer to leach with 10 to 25% of normal dosage of nutrients... dumping plain water is not bad but you risk "nutrient lock" .... its better to decrease the nutrient levels gradually rather then just stop feeding the plants.... so if you decide to feed with 10% of nutrients and then after (lets say) two or 3 waterings you decide to give them just plain water I would be ok with that.....


Comments

HEY MAREK, I have 19 plants but 2 or 3 seem to be stunted or sumting very small and growth is slow they are about 1week and 5days others seem to be doing ok. NE SUGGESTIONS can send u pics if u need em :D.

WEBMASTER:  mark@toronto420.com... and tell me when you send them (on this forum) .... I stopped checking my email as 300 a day is way to much.... 2 or 3 getting weird is not a bad ratio... usually I would pull back on nutrients for these plants .... and leech them for a week ......


Comments

Hey Mark, I was wondering if you had any suggestions as to what characteristics to look for in young seedlings that may give an indication of a plant's potential yield. I am always on the look out for a new mother. Normally I order my seeds, germinate, sex them, plant females outdoors and wait until the end of the season to determine which plants have the best qualities. I just wondered if there is anything to look for when plant are still young that may suggest production qualities. Thanks for your advice

WEBMASTER:  ...for outdoors, you are looking for the tall and bushy, a mix of indica and sativa... for indoors you look for a short and bushy, dominant indica gene... these are the only two characteristics I look for when making a mother plant....

Hey Marek, I bought another 400w system at hydrotech as of now i have 2 400w system in a 6by5 area i was wondering if i could use a 6 inch axial fan with a 235 cfm (ON BUSTAN WEBSITE) to draw the heat out as of now i am hooked up to a bathroom fan but i have to run ducting therefore there is really no suction happening from the bathroom so i just open the window and have three fans blowing around. (NEED SOME SERIOUS HELP AS MONEY IS KIND OF TIGHT AT THE MOMENT) Looking for a a cheap but affective way to vent. The reason i suggested the axial fans as u already know (THE ARE CHEAP AND QUIET) but i have no exp with them at all so was wondering if u would agree on 1 or 2 axial fans as my ventilation just for the time being or would it be a waste of money. TYVM n TC

WEBMASTER:  ...sorry but this will be a waste of money... the axial fan has power only when its completely unobstructed... i.e. no ventilation hoses... the moment you put the ventilation tubing on this type of fan the air flow will slow down to may be 50 CFM.... only inline fans have the torque necessary to do this job.... and unfortunately it takes over $100 to buy one of these fans....


Comments

when buying seeds that give a yield eg:325g/m2, is this all the seeds bought combined, ie: sometimes around 10 or 12, is there also a rough guide to spacing the plants within meter 2. Any help would be very grateful and appreciated.

WEBMASTER:  ...the number is absolutely meaningless unless you know what kind of a light the grower used.... I would guess-estimate that they mean under 600W...


Comments

Straighten me out here! ?. What is the 50W/cub ft. representing exactly? I had the idea that if I stay within that volume I should get the same yield than if my plants were in a larger volume with a 400W per say. Since I was in such a small area I thought 250W or 400W would be too large. I only have about 32” from the bottom of my vented light reflector (with glass) to the floor. And also why would I have the same amount of yield whether its 3 plants or 10?

WEBMASTER:  ..if your space is 4 feet wide and 3 feet long... and you have a 400W light.... 4 x 3 = 12, 400 divided by 12 = 33 watts per square foot....


Comments

is anybody else out there constantly dealing with powdery mildew, and marek have u ever had serious mildew problems>?

WEBMASTER:  ..sm90 works as a prevention and cure.....neem oil works as well ..... and this stuff kills mildew ..... in veg apply anytime, in bloom you can only apply until the 2nd week of bloom..... I usually find that when I spray with Neem I get no problems with mildew....


Comments

Hi Mark its me again. I have not had mites in over 3 years. I know you said spray dish soap or pokton insecticidal soap but thats not good enough. I'll be spraying for the next 100 years. I don't usually wine but these mites are a nightmare. I need something better than dish soap. It does not kill the eggs. I cannot afford to give my other plants mites. So I'm coming back down to get something better than soap. If you can't give me something better then I'll have to throw them out and get more without mites. PS please find some pentax or something like that so I can get rid of these bastards. PS have a good day.

WEBMASTER:  ..sorry I can not sell pesticides.....


Comments

hey bud, how are u?. noticed u offer free seeds to mmar card holders, wondering what strains are available? trying to find an old school med. ike Acapulco gold or Columbian red x anything indica?

WEBMASTER:  ..I offer 20 seeds (Toronto420 and OSB brands only) to medical growers, contact me and I will send you a batch... on the other hand I also sell clones to medical growers... I have predominantly indica strains, hash plants, white shark, ww x buddha, nl x haze, skunk no.1......


Comments

I apologize. I forgot to mention the 3 plants have been growing for about a week and a half. All three are about 3" in height. I am also using a low power fan for air flow.

WEBMASTER:  ..allow the plants to reach 1.5 feet high and start the bloom cycle....


Comments

If I am using a 150W MH bulb about 10" away from 3 plants, in a small space... lets say about 4-5 cubic ft. Using a reflectors on the MH bulb... can I still achieve a good yield? I read somewhere that 50W/cubic ft is optimal.

WEBMASTER:  ..150W can support a space of 2 x 2 feet optimally and may be 3 x 3 at best... 50W per 1 square foot is on a high scale... minimum is around 26W/sq.ft.... good yield is a relative word... I would expect 2 to 4 ounces from this light, whether its 3 plants or 10... Total per grow cycle... the only way to increase the yield then is to get bigger light...


Comments

hello mark, I am noticing some spots of yellow to appear on a leaf or two on two of my plants. I feed them about once every 4 days with a 1000 watt light. They are still quite young, about 2 weeks since the seedlings were planted. Do you think it could be nutrient problems, pests...?

WEBMASTER:  ..slight yellowing here and there is not a problem... see if you have any powdery stuff on the underneath of leafs... that would be mites... if nothing I would not worry... if the yellowing progresses start feeding them a bit more nutrients... and inch the lights closer so its 2 feet away from their tops ......

I regularly grow using a Rockwool medium (slabs in the 1 metre Aqua trays) feeding by drip feed. I am intending to switch to Coco slabs instead - more environmentally friendly and all that. My question is : Do you have any tips regarding the initial pre-soak of the compressed slabs or is merely the same process as with rockwool ie: a 24 hour soak in a Nute Sol with a CF of 6 and PH of 5.4.

WEBMASTER:  ..coco is more forgivable and generally easier so you still use the same methods as with rockwool.... coco tents to hold water longer so you may need to decrease your water flow but only if you notice some odd wilting....the issue of PH: in veg PH should be anywhere between 6 and 6.8 (EC well below 2000 i.e. normal feeding)....PH at 1st week of bloom should be 6.0, 2nd week 5.8, 3rd 5.6, 4th week 5.4...5 to 7 week should be 5.2 (you increase the EC as you decrease the PH, so you may start at 1800 EC at the beginning of bloom but you should be at 2200 or 2400 in the 5th and 6th week of bloom, week 7th and 8th is for gradual step down from EC down to 500 in the last few days before harvest, but PH can be any where around 5.5).

which is the best height for me to grow my plants in veg stage if my light can go to 2 and a half meters wit loads of space im looking to get a couple of once per plant is this possible in my room wit a 400watt light how high shall i leave them in veg for to do this many thanks

WEBMASTER:  ..with 400W you are still limited to 4 x 4 feet grow space and 6 feet tall... more space is bonus but it matters little, your lights have these limits .... veg 5 plants to 2 feet tall and bloom... 2 ounces per plant expected....


Comments

my friend has just given me three plants not very big but he has planted these into the same pot they are all growing into one plant if one of these is a male can i just cut it down will the others be ok even if the roots are growing together will it cross any females wiv just the roots there many thanks

WEBMASTER:  ..they are competing for space now, but being a weed they may survive for a long time.....its possible that the plants will be stressed out and chances are that one plant will overtake the others.. i.e. the stronger plant will take the nutrients and the weaker plants will die off.... you can kill the male without any problems, but the problem may be with the plants getting root bound......

Hey Mark, tomorrow will be the first day of my 6th week of bloom, so its starting to get close. I have read from you and elsewhere that most plants are ready after 6 weeks. I want to bloom mine for the full 8 and leach properly, but I also wanted to maybe take a bud after week 6 (impatient :). What is the best way to do this without stressing the plant, or is that even possible? (just cut off what you need, there is no special way of doing it) Do I cut the bud only, or cut at the base of the offshoot where it meets the main stem? (yes, but either way is fine) Would it just be best for my plant to leave it in tact until the end? Also, a lot of the hairs are turning brown now, maybe 20%. At this rate I'm not sure how it will last the full 8 weeks, but maybe this is normal. If it matters at all, I am growing WWXXX with a 400W MH, just watered for the second time with bud booster. Thanks a ton Mark!

WEBMASTER:  ..when you need smoke, you need smoke, the plant can be smoked after week 6 but it may not be the best pot to smoke as its full of nutrients and thus a bit harsh to smoke... but if you must go ahead.... I do not use the colour change of the hair as the only indication of readiness... I would leach for 2 weeks after 6 weeks of bloom to take out the nutrients.... 20% of hair changed colour seems reasonable at week 6 under 400W....


Comments

u said not to trim my leafs off just branches yea is it ok to do this in veg stage (only in Veg and never in Bloom) and how much shall i trim back and also is it ok to pull off any dieing leafs as u know this must happen to the bottom leafs which are not getting any light can i pull tem ones off and is it normal for these leafs to die off like (yes)

WEBMASTER:  ....you cut the plant in half, the plant will re-grow new branches below the cut.... when you make the cut you can also take off the weaker leafs.... I am trying to avoid you picking the leafs here and there (i.e. occasionally).. the point is to trim stuff off all at once and let the plant recover... recovery takes minimum of 1 week.... you can only make cuts like that when in VEG....

one of my plants has like orange spots on the bottom leafs but this is not spider mite as had before and know what it looks like what do u think this could be if it not spider mite u have any ideas thanks bud

WEBMASTER:  ..looks like the yellow spots concentrate at the point where the light does not reach.... there is nothing you can do unless you can expose them to more lights..... this is fairly normal as the bottom leafs get least exposure to light ... I would not worry...

Hi Mark, I'm helping a friend set up a grow room in her house. Is there a web site or publication that lists used equipment in the G.T.A? She is looking for 400w MH or a 600w HPS at a reasonable price. Thanks.

WEBMASTER:  ..I am not aware of any but I do find stuff off Craig's list and eBay.....

Hi Mark I have a major problem. I have lots of spider mites on my new clones. I hate these things with a passion. I really need a quick fix because they are the hardest things to get rid of and I don't want to spray every 3 days for ever. What do you suggest. Should I come see you.

WEBMASTER:  ...get this or Dr.Doom, both pesticides, turn off the lights for the next 2 or 3 hours, put on a mask of some sort, grab each plant individually and blast the entire plant from below...... that will kill it ....

mark... just wanted to let you know I think everything you do here is awesome. Im a regular reader though I don't often post. I find it informative and proactive to read about other peoples problems and your "solutions." Most of the stuff gets rehashed over and over but when you're catering to newbies that's how it goes. Im by no means an expert but I've had a decade of practice outside and a few years indoors. I learned with the help of my friends...and the school of hard knocks and shitty harvests. If there's one thing I've learned...its that there are no shortcuts. They ALWAYS come back to bite you in the ass later. If people want exceptional results (and we all do) there's no substitute for genetics, exceptional lighting (1000W bulbs for bloom), exceptional ventilation (bigger is better) and exceptional cleanliness. If your garden is weak in any 1 of these areas...that's when problems can and will get a foothold (bugs, mold, mildew, crummy yield etc). Most gardeners should worry more about these basics and less about the fancy nutrients and processes. I manage to get excellent results (yield and quality) using nothing more than the basics and hardware store nutes in promix...Just my 2 cents...

WEBMASTER:  ...that is exactly how I feel.... there are no miracles... there is only hard work.... Thank You.... I do answer some questions that I feel are pretty advanced...

hey bud, how are u , quick question, due to something already on the go and something new ready to start wondering if i can veg with fluorescent in an adequate box until 6-8 inches then flip them to 10 inch pots until i can get some 5 gal. bucks lacking separate spaces for the perfect project. being on odsp sometimes cash is hard, fuck who am i kidding its always hard. flipping then plants should finish approx. 18 inches? thanx man.

WEBMASTER:  ...sounds reasonable and I would proceed..... but I am worried some may be taller since the fluorescent light makes plants stretch a bit more then under a bigger light.... closer to 2 feet tall finished...


Comments

Just wanted to say that I got my seeds today and I am very pleased :) you rock man. also had a question: I live in Canada about two hours north of Toronto and I was thinking about starting some seeds inside in beer cups in the closet. (yes) I only have about 2'x2' of closet space and 6500 lumens in fluorescent lights. (its enough) I have been able to grow plants under that setup before. my question is if I start them inside, when/at which stage of growth should I plant them outside? (I take mine as soon as the reach about a foot or so, but they can be as small as couple of inches tall ... they are weeds so they will survive) I haven't been able to find any last frost dates, but farmers around here tend to plant around may 15.( I kid you not, listen to the farmers because this is what I do)

WEBMASTER:  ...the bigger you get them indoors before the mid may outside planting season begins, the bigger they will get outdoors.... the more yield you will get....

Hey Marek, I am adding either a 400w 0r 600w to my room which is 6by5 as i already have a 400w in there now but i have 19 plants so i am assuming i am going to need more light, as u indicated u would have only grew 10.(LOL to late i have 19 at 1week and a day or 2 old. I guess my question is would i get a MH or just get another HPS Hortilux. also my ventilation is only a bathroom fan and i have a few strategically placed fans to increase ventilation, also i was wondering if U SELL EQUIPMENT (USED OR NEW) also what kind of ventilation to recommend for a 800-1000w room (LOOKING FOR THE LEAST BIT OF NOISE) One more for the road LOL when using promix and tap water left out for 24hrs I mix my nutrients into the tap water, but should i be PHing the nutrient/water mix before i feed my plants? as i do not as of now. (not necessary to pH the tap water as promix buffers the tap water ....i.e. makes it acidic .... )

WEBMASTER:  ...for new equipment in the GTA I would shop at Hydrotech and they don't pay me to say this ... they always have promix in stock and they fully agree with my way of growing.... used equipment: sometimes I have old stuff I trade with others but not that often ...... I may have a 400W kit kicking around somewhere but I may want to keep it for some small scale experiments ..... check Craig's list or eBay for used stuff... for 800W/1000W of lights you would need a 100 to 150 CFM fan, CFM is the rating for an inline fan....for now all you would need is this fan .this fan is already almost whisper quiet so I would not worry too much.....if you need a carbon filter, you would need this fan, bigger because the carbon filter restricts the ventilation and in the summer you need more power..... the bottom line is that if you already have a HPS spectrum the next light should a Metal Halide.... If you want to splurge get a 400W MH with SunMaster Warm Deluxe..... but I am ok with a cheaper bulb...

Its me again. I read on the net they are going to stop giving growing permits after 2007. shit I hope not, I already had health Canada weed and it is garbage. I think they let it go to seed. What do you think. Thanks again. The cell phone.

WEBMASTER:  ...all bull shit.... rumors at best.... if the conservatives win a majority government then I would worry but not until then,....

To TONY, they are both true readings the pot and the wall are different temps.

WEBMASTER:  ....I average my temperatures... some right on the ceiling read 34 C but 24 down at the pot level... the average being around 27 is great for me.....

Hey Mark, I see a few mites on my clones and some of my plants, I know they just started cause there are very few of then something like 20-30. I threw away the plants that seem to have them. I know my temps were a bit high lately but I seem to have that under control now. can I get rid of them? I'm preparing a few plants for the outside soon, and am wondering what will happen to the plants when they're outside inmid april and have some mites on them, Will mites still attack my girls outside? Anyways Can I just spray them with neem oil while they're vegging under fluorescents? (of course, absolutely, you must) 110 Watts. Do I have to turn that light off too? (I would still turn them off because the lower the temperatures the better) it seems its not that hot under there, you mention anything above 25 Celsius is no good. (absolutely) How do they die from neem oil? Muthafuckin mites! I want to fuck their reproductive systems up! Please help!

WEBMASTER:  ....10 ml of regular (NOT the anti-bacterial stuff) green dish soap per 1 liter of tap water, use this sprayer (picture on right) and spray every two days for one week.... when outdoors or in bloom or anywhere where you have problems with mites you can spray every 3 days for the first week, stop, spray once a week afterwards...... if you spray once a week until the end of July there should be no problems..... when outside the mites are not even close to being as bad as they can be indoors... the temperatures outdoors often drop to to below 15 degrees Celsius so the mites can not really get hold.... now if we had a really hot summer, then the spray should help a lot.....

Hey Mark how are you hangin. Just wondering if I should aerate nutrients with air pump, when I am already adding hydrogen peroxide to raise o2 levels Thanks Pal.

WEBMASTER:  ..aerating the water is always a good thing ... the wisdom of using CO2 is split among my friends right down the middle so if its working for you its all good....


Comments

hi mark; i have two thermometers, one in the pot and one half way up the wall. the one in the pot reads 21 and the one up the wall reads 28, which one is the true reading? im in the six week of bloom. thanking you in advance for your wisdom.

WEBMASTER:  ..your temperature is the average of the two..... around 25

Hi Mark. I"ll pick the cell phone RAZ found on Sat around 2:30. Thanks Man I wasn't thinking to well when I sat the cell phone down. Its my wifes. Seeya soon.

WEBMASTER:  ..another good deed performed by the brave crew of Sublime cafe...lol. :-)


Comments

is it possible for the seed to germinate upside down and the root to sprout up? this is what looks like is happening to all of my seeds after 3 days of germination, maybe it is sprouting but it looks like its rooting against gravity?

WEBMASTER:  ..are you sure its not a little stem poking through, they do resemble roots at the very beginning....

DNF assumes that your tap water ec is 300....which for municipal water supplies is pretty much standard....as well as a ph of 7 which also is pretty much standard for municipal tap water.

WEBMASTER:  ..correct...that's Toronto water ....

Hi Mark I was just wondering how often should I change the nutrients in my reservoir. When 1 do should I use an ec of 500 plus the ec from tap water around 800, so final ec of 1300. and should I run this through system 8 times. What do you suggest. What if I have reverse osmosis water with a reading of 0.00 would I use an ec of 500 with pure water to leach. I wonder if all these recipes are adding the tap water ec on top of the nutrient EC. EXAMPLE DNF sais to use an EC of 2000. now is this a reading of 800 tap water plus 1200 nutrients to = 2000 (YES) or RO EC 0.00 plus 2000 worth of nutrients to me it seems maybe to high with RO (it is too high). Do you add 800 to the RO and 1200 of nutrients to = 2000 (yes) or do I use 2000 worth of nutrients. PS I've wondered for years. Tanx again MARK. your a good MAN. Keep up the good work.

WEBMASTER:  ..if your water tests at 300 EC you add nutrients to measure 2000 EC. i.e. 300 + 1700 worth of nutrients.... if you use water from a reverse osmosis filter that tests at 0.00 EC, then you would add 2000 worth of nutrients..... the pen you are using only measures SALTS in water and it does not distinguish between nutrients and some crap our water comes with.....

Hey Bro, how art thou; In your opinion. When do THC levels start to diminish. Is the best way to judge this, by the color of the trichomes?? Thx a Bud!

WEBMASTER:  ..when trichomes go opaque at over 60% (of all trichomes) its time to harvest... I frequently let my plants spend an extra week in bloom leaching and the taste and the flavour and the high is amazing..... so the decline of THC happens sometimes after a week of what is normally an 8 week bloom cycle.... but that's all I know.....


Comments

OH i forgot is good to have a oscillating fan going 24 hrs or should i shut it down at night when lights go off? TYVM also sorry bout the posts as i do not know what happened i only hit it once

WEBMASTER:  ....oscillating fan should only be ON during the day, but its not deadly if you keep it running all the time.... the ventilating fan (preferably inline outtake) should be ON for 24/7.... no worry about the posts...


Comments

Hey Marek, I was wondering when i should be venting? also what do u think my temperatures should be at this state? (plants are 6 days old from seed) I Have them from 27 to 28.5C and humidity is at 30% but can increase to 50-55% max if needed. What are ideal temps for when lights are off. Using 400w Hortilux in promix. Also do u have any little growing tips on the strains that i am growing (WWxB,BBskunk,NLxB,skunk69) ALL help is much appreciated. TYVM n TC

WEBMASTER:  ..venting happens for two reasons... one is heat control and the other is smell control....so ventilation should run 24/7...daily because you control heat and at night because you control smell.....you have correct temperatures and correct humidity.... when lights are off the lowest temperature can be 20 degrees of your daily temperatures... so no lower then 8 degrees..... at 15 degrees mites leave..... sorry there are no secrets... the grow guide is the secret....

Hi Mark, I recently have been on this forum asking you about SPIDER MITES....fk'n mites! I have used insecticide once and neem oil twice. I have gone into bloom 2 days ago...but still suspect a few are around, even noticed a few on my 4 clones that are two floors away....sheeesh! Last night they appeared in my dreams....fk'n mites! Can I spray them with dish soap and water every couple of days for a few weeks while the plants have not formed buds? I am keeping my temps down.....72-74 out of paranoia, what would you do?????? 1000w, 9 plants,18" tall, pro-mix, good vent. Thanks man.

WEBMASTER:  ..10 ml of regular (NOT the anti-bacterial stuff) green dish soap per 1 liter of tap water, use this sprayer (picture on right) and spray until you are in the 4th week of bloom.... spray every 3 days for the first week, stop, spray once a week afterwards......

growing outdoors in black grow bags - 5 gallon and 71/2 gallon - in northeast - what medium is best in grow bag - have always used promix and some additives - what about fertilizer - have used fox farm liquid - but have not been satisfied with results for season - what better fertilizer or medium might I try. thanks, tiffy

WEBMASTER:  ..my first impression is always... "you did not give them enough nutrients".... outdoors I prefer miracle gro - ultra bloom from July till beginning of September and whatever brand of nutrients for the veg period..... if you continue using the fox farm stuff and I like this stuff.....the lable tells you to feed X amount, I would add X + 70% more at the heavy bloom period of July till September....

horneygirl.... seems like u might have a leak in it ?? maybe the flange is not properly installed ?? also carbon filters are not judged by the CFM method ... but by the pounds of carbon in them... i have a 16 pound carbon filter hooked up to a dayton 265cfm blower and it works great no smell at all .. really all u can smell from the output exhaust is the carbon itself ... smell the filter without running the fan ... thats what the purified air should smell like .. also make sure all your fittings from the blower to the flange is sealed air tight and also the flange to the carbon filter is air tight so there is no air leaks u want all the air to travel threw the carbon filter peace

billy... depending on what kind of proportioner u have ... 4 way ? 5 way ? and plus i would not use this piece of equipment ... also i dont know if your proportioner is a stand alone or if its mechanical ... tell u the truth it seems like a waste of money for the application you are trying to use it for ...the only thing that comes close to what your trying to use this equipment for is the eliminator R/O system which works wonders.. for clean applications of nutrients they work great ..they cost anywhere from 200- 400 bucks depending on how many GPD u need but the proportioner is really useless for growing ganja .. peace

Have a question due to odor i have a big carbon filter that is new installed on to a fan actually bought it as a fan filter combo, now when you smoke a cigarette or joint in the room and the fan comes on you can smell it through the house slightly. is this the way it should be is that the best it does, what about when the plants start to stink? I am using a pro-filter with activated carbon. its a 400 cfm filter i think and the fan is 449 cfm could it just be i am pulling air to quickly through the filter cause this combo cost $600.00 from bustan in toronto...any ideas would be appreciated

WEBMASTER:  .....there should be no smell what so ever when installed properly, and you have a good combination of can and fan, if you consider that the carbon filter reduces the fan rating by 100 CFM... one way to slow down the air flow, if in fact the fan is too fast, is to put a "kink" in the exhaust line... one 90 degree kink decreases airflow by 50 CFM!!!!....

I have a 1000 watt HPS bulb and i want to start growing from clones i would like to know what size pots to grow in and what is the maximum number of plants i can grow under this light, lots of floor space in my room..
