Mainly you want to put a layer of rocks at the bottom of the net pot.Then set your rockwoll cube on this little layer and fill the rocks around it.Then like Everyone said keep the water level right below the net so the bubbles pop and get the rocks and the rockwoll cube.
J DOG 6000 Reviewed by J DOG 6000 on . Clarification on DWC... Ok... I understand the concept of DWC, oxidizing the water while the roots are constantly submerged... but how do u start (for example from seed) if there are no roots? I see all these DWC setups with hydroton and other grow mediums... but isn't that just to hold the beginning roots and main stem in place... so the roots grow out of the net pot, and then into the oxidized water, but how do u get the roots that far to begin? I guess what I'm really asking is... are the net pots, with hydroton Rating: 5
