It's my own design. Just 4 4-3/4"x8' vinyl fence post ( the larger ones ). Then ran 1/2" s40 PVC pipe thru the middle. Then drilled 2 3/4" holes ever 6" for 3" net pots this should make 16 holes. I also offset the holes by leaving 3" on one end. The s40 PVC has 17 mister sprayers in each tube, one mister in-between each pot. A 900gph pump was plenty to spray for all the sprayers. I also installed shutoffs for each tube so I can shoot pressure thru to clear sprayers. I used a vinyl piece of gutter for the tubes to drip into then run off into a 14gal tote. I keep 40l in my res at all times. There is also a few tweaks I've worked out but I usually go 2-3 days out of town every week so it runs great on it's own. I run my ph at 5.5-6.2 and usually have to add a few drops of ph down after I've been gone a few days. But if you would like to build one I can send pics and give u my personal riu email if u need it. But as u can see it definatly works! It's basically an aero-flo/ NFT custom.
