Yeast for C02?

Given that spending money on a timed C02 pump setup it pricey.

And given that yeast + sugar + water = Alcohol + C02.

Would it be feasable to use yeast to give your crop the C02 it needs? Yeast is cheap to buy, and as long as you keep it fed with sugar and water (also inexpensive), it keeps creating alcohol and C02.

Plus, nothing goes great with illegally grown plants like illegally brewed moonshine.



So, yea or nay?

definitely. i use old bottles of all different sizes. seal a piece of fish tank air hose into the cap. after that you can just put the CO2 wherever you want. i like to put some in the canopy on some dnagling in front of the fans. My grow is only 2x4 with the plants in 2x3

yeah i use it
