lol Bro, yeast is a living organism, It uses oxygen and releases co2 as a waste product. The co2 it releases is used by the plant making it healthier, and the plant releases oxygen. Green plants use Co2 as part of the photosynthesis process. Therefore the yeast releasing co2 is a natural way to boost plant metabalism. In an indoor environement such as I have,(no outdoor air exchange) it may help the plants develop, or so I've been reading. I put 3 packages of yeast (disolved in warm water) with 1 cup of sugar into 3 quarts of warm (not hot) water. I put it in a gallon jar covered with cheeseclothe and held with a rubber band. Hope that helps, Sis
kuulbns Reviewed by kuulbns on . CO2. Is it worth it Hi peops, Just wondering if you experienced growers out there think co2 makes a big difference to yield. I will be starting my second grow in a couple of weeks and have read Encatuse's link on how to make a "yeast co2 maker" and it seems quite simple but will it give me much more bud. Cheers :D Rating: 5
