i just saw the co2 info in the 30 days flowering thread and think i'll give it a try. my area doesnt get too hot so i can kill the fans for a couple of hours when i first open the water bottle.

from what i understand you fill a water bottle half way full with water and add a tablespoon of sugar and a tablespoon of yeast and let it sit for 12-24hrs. you would then open the cap and let it sit in your grow room to supply c02 for the plants. not sure if this will be good in my area though, does anybody know how big of an area this will work with?
