Thanks for the link Scarlet, thats a great diy tutorial.I think i'm going to build one, I've always used a drip system and now I am very interested in DWC. So I have a few questions that might help some others out as well as myself. In dwc when you place your clones in the net pots with your hydroton your supposed to keep it one inch away from the roots right? If thats the case when you first put your clones in the net pots no roots will prob be exposed so will the roots contained in the hydroton still have nutes deliverd to them?
