Aero/NFT combination with CLOONER
Sorry, is in spanish but easy to understand.
After research I came up with this system. It has all the benefits on an AERO and a NFT system. Is the one I am currently using and working on. You can add so many things like stands for light or tall plants, thermometer, high capacity reserve tank, even a cover for those hot places that burn your crop. Nothing to it.
Just some rain gutters, an air/water pumps, 1/2" pvc pipes and connectors for delivery and recovery, air stone, easy access lid to maintain/clean/fill, and filters. Mine has a 22 gal. tank. I grow tomatoes and herbs in it with no problems so far. Hope it helps you build your own at a minimal cost of the ready-made systems that are expensive.
