RastaKaze Reviewed by RastaKaze on . CO2 in the grow room I have a 2'x2'X3' grow room. I read about adding CO2 to your room to make the plants grow better. In a book I read, the Cannabis Grow Bible, it said that CO2 can possibly double your yeild. What I was thinking, since CO2 generators are expensive, to do the baking soda and vinegar reaction that will release CO2. I calculated about 1 lb of baking soda reacted completely with vinegar every other day inside the grow room will give the plants plenty of CO2. Just an interesting thought. Any comments? Rating: 5
