To protect from power outages, I aim to have a least a couple of inches of roots in the solution at all times. Otherwise I would aim to keep none of my roots in the solution. I have a way to vary the level of nutes as the plants grow, but I keep spraying the entire root system about every 10 minutes.

I hope that gives you some ideas.
Thats not really DWC....thats more of aeroponics...which is great and thats a good idea of the sorta hybrid of the 2 because with aero if your power fails its bad news real fast.
Cyclonite Reviewed by Cyclonite on . Water Level in DWC? I have read many places that when the roots have not grown through the netpot you want to keep the water level 1/2" above the bottom of the netpot, and when they have grown through, keep the water level 1/2"-1" below the bottom of the netpot. Now, I never see with these figures how far into the netpot you are putting the plant...Do you put 1" of hydroton in the netpot, the plant on top, and then surround with hydroton? Or is that plant resting on a larger layer of hydroton? Basically I guess Rating: 5
