Just go to WallMart and get a 12-20oz CO2 tank for a paintball gun and go from there. Much easier to run a hose and valve than to deal with yeast
i got a 20 gallon tank off ebay for 40 bucks and i get it filled for 15... havent decided the best way to do it yet though.. last time i just gassed the tent for about 45 seconds and then hit the fans... guess it was a success lol my plant didnt die.. anyone have a better method ?
I haven't actually done it so I'm not sure. From what I read you can leave on a constant flow to maintain the proper PPM of Co2 in the air. This isn't a good idea if your doing this in your bedroom closet. Do it wrong and you will asphyxiate yourself. Co2 is what plants absorb/"breath" and they give off oxygen in return. So do your research and let me know how you make out
