...coming along I am rather impressed with your little DWC container, I've been considering a DWC experiment for personal. Due to the reason why I grow most of what I grow I try to keep it as natural and clean as possible. Several of the folks that my herb goes to have medical marijuana licenses for one main reason, they were taking so many chemicals that were all replaced by cannabis. And therefore I espeically have no desire to put any chemicals in their replacement therapy. But I've been hearing from folks about organic hydroponic nutrient solutions... will you be going chem organic or combo of both for your dwc?
(P.s. just caught the part a few days ago about mercury poisioning and it sounding like what your looking for good quip, if I ever breed a sativa/indica hybrid that exemplify's those characteristics at optimal harvest I gotta name it mercury now...)
