I've built a homemade DWC system. I'm about to transplant clones (currently in rockwool) into the 4" netpots with hydroton rocks.
My question is - where should the water level be in relation to the netpots? Should the nutrient solution be just below the netpots? Should the water submerge the netpots a little? Or even higher, to where the rockwool sitting close to the top of the netpots be submerged in solution?
Also, seems like a lot of people on this forum say oxygen is great for the roots. So do you start to lower the water level in a DWC system as the roots grow longer? To make them stretch more for the nutes? Or do you keep the water level the same throughout veg & flowering?
Thanks - I'm learning so much from this forum...
