DWC seems to be a "set it and forget it solution" for several things. I had tremendous luck in the greenhouse last year with cucumbers and I'm going to do just DWC in the greenhouse this year, cucumbers and tomatoes. Maybe one setup of lettuce. When I do lettuce, I don't recirculate the nutrient solution, just apply air. With the cukes and tomatoes, I'll recirculate.
I am anxious to work some "outside" systems this year. I don't have the light intessity systems to do cukes, tomatoes, or peppers inside as of yet.
"Set it and forget it" is a great term for this.
Hoop house or greenhouse is in the future...I see no reason for it NOT to be completely hydro.
