The more root mass that is in the water, the more air you will need to sustain them. If they start turning brown or getting slimy, get more air in there ASAP. Also be concious of temp of your res, mine is about 75 on average during the summer months which is the high end of the spectrum so be careful.

If I were to grow cannabis, I would only do so to supply myself and my close friends. Doing this would take myself and my friends out of harms way by knowing the source of our cannabis, as well as take hundreds of thousands of dollars off the black market annually. It would also lower the demand of black market cannabis, and would ultimately help keep cannabis out of the hands of minors.
