<NFT System Description> I built the Closed NFT System after reading Stinkfist's(I think that was author) Aero PDF somewhere. I committed the basics of the design to memory and decided to change a few things to fit my setup. Some of my concerns were this: 1) 3 posts for my space not 2 or 4 2) Modular 3) Removable for Maint. 4) Incline height 5) Sprayer access 6) 1/2" PVC inside post not elevated to ceiling. 7) Post Length (72" I cut down to 68") Basic design is post with a Drill hole (sized for ez clone sprayers, originally I had sprayers). The water aerates partially from the ejection at the drill site and from the waterfall into the res. The first post I put together had a cap leak (caulking was dry and I didn't really notice till I was on 2nd post). I had a tiny leak 2 weeks into veg, so I made a replacement post and the transplant of 5 plants took about 10-15 minutes. Very quick (and thats with almost no room to work in the room. There are 3 posts of 5 sites each. The middle post is staggered so that each plant has approx 12"+ between any site. I removed the sprayers because I liked the water flow, the peace of mind, and I really wanted to go NFT (Always liked the idea and efficiency of the idea). (Holes face straight down). I was going to go full NFT after not liking the sprayers and was going to replace the pipes with open ends essentially like 10 big drill holes on ends. But decided to just give it a go without sprayers and liked when I saw, it was a comfortable medium between what I knew and what I wanted. I used one of the Yellow and black combat locker looking home depot storage bins (bought 2 ($7.99) extras for easy res change / dmg / extra tops) I covered the reservoir with Panda Film to help keep light out. (I am considering doing a DIY if the grow goes well so I want go into too much detail here, I will add a link to that DIY when/if it exists later) <Strain Info> Querkle again!
