Co2

What are some ways that i can get CO2 in my growroom????

milk jug
2 cups sugar
1/2 cup yeast
3 cups water

mix it up in the milk jug, poke two holes in the top for the c02 to release, shake the jug everyday, make new one every 10-14 days...good luck

Thank you...........

make that 2 tb spoons of yeast, not 2 cups. my bad. dunno if that would have been good or bad.. 2 tbs and youll be set tho.
Unless you want to spend the cash on a generator? pricey tho
butter101 runs one of these and says it works great. I am using the DIY yeast and it seems to be working as well...

neHydro.com, Hydroponics and Gardening Supplies
good site for a co2 generator

whats DIY yeast....????

"do it yourself" in the grow faq, the little tap on the top left of your screen, will have all the anwsers to most of your questions

Does baking soda and vinegar work????
