Homemade CO2


New Member
Hello I was wondering if anyone has used co2 enrichment on the cheap with the 2 liter and yeast and sugar? I am wondering how much of h2o, sugar, yeast i need to mix up to be somewhat effective. What does the temp of the water have to be? Does it even work? Thanks for the input.

Ive done it before.

Your growroom needs to be enclosed during its daytime for it to work. Also tubing directing the co2 might be needed since its heavier than air.

Google "DIY aseptic Co2 cannabis" to fix up a bottle.

I dont have any stats or ppms or anything, but extra co2 doesn't hurt.
