I am starting this thread to get people talking about soil-less 1000w set-up, there problems and fixes. I am currently using sphagnum pete moss as my grow medium and would like to know if anyone else uses it as well? It is great because I use Optimum hydroponix neutrient schedual (the pete allows this) for all my neut needs. I also would like to know if anyone knows of a method called "single stock" I have heard great things about this method so please post away!
