I have used co2 since the first time i grew. I started with the old yeast, sugar, and water. i took a milk jug and cut the top off. I filled the jug 1/2 way with warm water. then added about a half cup to a cup of yeast and then about two table spoons of sugar. It smells like old, stanky bear that has been sitting in your house for yrs! but it will produce co2. i then duct tape a hose to the top, and ran it over the top of my three little plants. i plugged it and stabbed little holes ever inch or so.

to be honest,...after trying all the different methods, i would just invest in a co2 tank, and a regulator. It will run you about $300.00....but WELL worth the invetment. laterz..
