Up until the past 2-3 months, all my hydro was DWC...1st, germinate seed...or germ in rockwool or rapid rooters, then treat as you would seeds started in peat pellets...once the roots are showing out the sides of whatever plug you germinate in...you transplant to netpots with hydroton or other hydro medium...when you transplant to net pot...fill up your tub/bucket/whatever with ph'd 5.8 RO/distilled water with some superthrive, B-52, B-1,or Liquid karma (in other words, some type of B vitamin based additive for propagation)...make sure that the bubbles are right under your netpot...make sure that the water level stays right up to the bottom of netpots and be patient...In a few days you will see pristine white roots poking their way to the water. you see the bubbles pop and make the Hydroton rocks moist...the roots seek out this moisture...goodluck.lw It has always worked great for me...I even clone straight into
hydroton netpots(but that's another story)
