cuttings stems must be kept in continual dampness but not too much. So they can dry in pellets if the frequency of waterings is too low. Good systems for cloning is waterfarm like systems in grow rocks, in rockwool with one watering every day till roots, and bubblers, stems staying above popping bubbles. But always with rooting gel or powder. In dirt it's good also.

fhydro Reviewed by fhydro on . s Ebb &Flow as good as Aero or NFT or Drip? Hi. what Iā??m wondering is: is there really much advantage to using more complicated systems such as Aero, NFT, DWC or Drip, instead of just a simple ebb and flow? I can think of the following advantages for E&F: 1) The use of a medium (rocks/coco) so the roots stay distributed evenly and not matted together, and to hold microorganisms. 2) It forces the stale air/plant gasses out of the medium with each flood, pulls in fresh oxygen. 3) NOTHING TO CLOG; no dozens of f***ing Rating: 5
