Co2?

oK, my question is What does co2 do for your plants. And how should i use it. And what stages does it help?

Comeon, Someone gotta know sumthin.. ;P

That info is everywhere. Any specific questions?

Growing cannabis ( marijuana ) with C02

Theres directions in the grow faq on how to make your own co2 with sugar, yeast, and water. Should that work? If its in the grow log then its been proven right?

I don't know if I would go that far, lol. It sure sounds good in theory, but I doubt there has been any rigorous testing.

Should it be safe to try?

And also, one of my plants, has 2 leaves that are lookin to dark around the edges, kinda like a blackish color. Is this nute burn? Im feeding them little smount of nutes, only 3 weeks old.

3 weeks old is a good time for nutes, its when i started using mine i think. after a while a seed uses it food store and needs nutes. depends on how big they are, maybe a few pics to identify your problem. to answer your CO2 problem, plants carry out photosynethesis to provide themselves with food. CO2 is required for this process but the addition of CO2 is not essential for one plant, but the addition of it will only help. they only need this when the light is on, when the light is off it requires oxygen as it carries out respiration like we do. there is no such thing as too much CO2 as after a while, no matter how much CO2 there is present, it stop becoming a limiting factor as the plant can only carry out photosynethesis at a certain rate depending on other factors. in other words after a while more CO2 will no longer increase the rate of growth whilst the lights are on. hope this helps

this is a proven methoid to make co2 and it makes a big diffrence i only use it my bud room but it can be used for all stages.

now when i first started useing sugar and yeast i got the 5 gal bucket and hose but i only put the hose above half my plants. well thes plants were twice as big i got anther 5 gal buckes and more hoses.i use 2 5lb bages of sugar and 3 table spoons of yeast every week.
