Ok so we have all read the threads about making co2 for you grow room with little to no money spent. Get a bottle add water, yeast, and sugar. My question is, if I attached a thin hose to the top of the bottle and ran the hose to the inside of my hempy bucket, would this increase yields? Or would it be better to just set the hose on the top of my plants? What do you think?
