This is a NFT system made with 5x5 Vinyl Fence posts. I didn't like the idea of the PVC Tube method because I wanted a lot of space for the roots. The stand is made of 3/4" PVC thick tubing. I baught a 8' peice of this fence and cut it into 2 4' sections with 3 3" net pot holes on each one. I then made a stand that would easily cradle each end of the fence post and are removable. The pump is a 396gph EcoPlus submersable pump. The pump goes to a peice of pipe that has 2 nipples(tee hee hee) that go into the top of the intake end of the fence post. At the other end (pic 4 & 5) there is a bulkhead that goes down to 2 nipples that I will attach a hose to that goes back into the sump. This system costs about $100 (mostly the fence post) and I think is great. Light, Effective, and great for 6 big plants. I plan on doing a SoG with this. If some of you are interested in building this (or something similar) I'd be more than happy to give you measurements and a parts list. Thanks for veiwing.
