Or when they are younger you raise the water level and the air stones closer to the bottom of the net pot. Then lower the water level once you have ample roots sticking through the pot.
Zandor Reviewed by Zandor 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
