Thanks man. I'll check for the litmus paper version next time I'm at the grow shop. 450 is a little high for me. I'm saving for a reverse osmosis machine right now. After that I'll be saving to set up a bigger grow room for flowering. But if I can get a litmus paper version, I'd do that...

let us know how that test turns out man. by the way, how much does one of those co2 testers run for? can i find one for cheap?

thanks a lot leafsmell

where is everybody? doesn't anybody do this stuff?

Thanks a lot for all the replies. I'm thinking I'll try the sugar and yeast. I'm also thinking I'll still spray the plants, but I'll try to hit the undersides of the leaves and stay away from the tops. Oh, and if I get the tops of the leaves, and the don't get burnt spots, is it ok then...

thanks a lot man. i'll stick to just using the sprayer to clean off the plants in the veg room. sugar and yeast sounds like a better alternative to the carb water.

Thanks a lot for the advice. I've read about fermenting sugar with yeast to produce co2, but I havn't really thought about trying it myself for some reason. I think I am gonna try it out. The space in my flowering room is really tight (5ftX5ft with 12 plants at the moment, 10 more on the way)...

you can definately do it. a lot of people keep clone mothers alive for five years or more. whether or not it's really worth it is another question. thats a long time to wait for a harvest. why not just grow a few plants at a time and put them outside for harvest each year. also, a sativa...

for seedlings you don't need nearly as much light as for older plants, but id still try to abide by the 3000 lumens per square foot rule if you can.

most people like to stay away from stuff with time released ferts. im using a soiless mix that doesn't have any nutes. it seems like a lot of people like that. i tried using a cheap walmart potting soil once and it was absolutely horrible. the drainage sucked completely. im not sure about...

i dont have any co2 system at all, but i do have good air exchange. i've heard of people spraying carbonated water on plants to give them carbon dioxide. ive also heard conflicting accounts about whether or not its ok to spray flowering plants. i would like to do this to give my plants extra...

the lights will get hot like any other hid. i just use regular fans and keep the doors to the grow rooms open with the fans blowing the heat from the lights out. if you dont want open doors you will need one of the exaust fans to take care of it. if you go that route, its a little cheaper to...

GROWFAQ this is the link to the faq page that suggested the 21 hours of light at the end of the flowering period. i just read it over, and my mistake: it didn't claim a 40% increase in yield. i think its saying that it will increase the length of the photo period by 40%, while giving the...

A grow video I saw said that toward the end of the flowering cycle you should extend the light hours to fourteen hours. It said that your yeild would be increased without any danger of reverting the plants back to veg. Also, in the faq section of this site I found a thread that suggested...

I go to the actual store in cranberry. it kicks ass. the people that run the place are always really helpful and i know that you wont have any regrets if you buy from them. the only complaints that i have with htg at all is that sometimes they only have the expensive shit and nothing on the...

doesn't this make it kind of a pain in the ass to know exactly when to start flushing? do you guys have any problems with that?

oh, i think i might have read that article on jstor once. it sounds cool, but im not too convinced. i cant go back and look at it now cause i dont have a jstor membership anymore. im almost tempted to try it, but i'm pretty sure it would just stress the plants. does anybody know if carbon...

at first i was taking this article seriously, but there were just too many things that sounded like bullshit. and i'm tired of hearing about birth control pills affecting the gender of weed. it is a hormone produced by humans. how could it have any effect on plants? im surprised everybody is...

I think a lot of strains can have those characteristics. Im pretty sure all of them have really small white hair looking things and I have sprouted both big bud and jock horror that had purplish-red stems. Ive only grown out five strains so that coloration is probably pretty common.

Nobody really knows the genetics of the original purple haze. I feel that it was probably a variety of different strains that were given the name because of a purplish tint caused by low temperature. Not necessarily produced by the same grower and not necessarily related, other than just being...
