I'd like to know what level you keep your water also. I am struggling with some newly planted sprouts in a DWC setup. My roots have just started falling below the netpots, but the one that hasnt dropped roots yet is starting to wilt and has me worried. The rooted ones I have the water level about a half inch to an inch under the bottom of the netpots. The one that hasnt started dropping roots yet I have the water about a half inch up the netpot bottom but it doesnt seem to be helping.
Its the one on the top left of the picture.
