aeroponics is still the best but dwc is a good second way to grow.Yeah stealth hydro are pretty exspensive.I built similar and sell the 6 site basic setup for $70 with hydroton heavy duty netpots,rockwool,cloning powder,pumps,misters,fox farm feeding chart ands schedules and I can add other extras at low cost but if you got money to burn stealth is ok but exspensive.I also built those single bucket plant setups but as aeroponics and I use larger netpot lids that can hold 6 inch rockwool cubes for stability.All hydro kicks soils ass.But I think it goes aer,directline feed,dwc.bubblers,floodtables,and bringing up the rear soil
