Turtle is right. I grow from seeds with rockwool cubes and little netpot. If the plant has got or no roots, it's the same. The popping bubbles damp the rockwool cube ( if the level of water is high enough ). It's better to wait the roots to go out from the cube before putting it in the DWC system. Rockwool keep dampness too much, and i notice better progress to plants that have been put in DWC once roots out than the other ones. If they have no roots out, you better feed them manually, once or twice a day.

fhydro Reviewed by fhydro 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
