Stink bud I've read so far through the first 48 pages of this epic post and inspiration was a flame! I'd love to read your high times article, how many have you written?
Here's my mock up

I'm only going to do one row of 5 plant sites spaced 5-6 inches apart from one another, and I decided to go with 4" PVC tube instead of fence post for aesthetic reasons alone, (although it's just dawned on me how the net pots will awkwardly set in a round tube rather than flat post)I have the tube go into a 4" to 2" down tube where I have a screen awaiting curious roots before they get in to my reservoir. Also my reservoir will be a 15 gal cooler. One of the reasone why I go down to the 2" down tube is because it fits perfect in a cup holder on the cooler. I chose a cooler because I am all too accustom with root rot in DWC and if I throw in a frozen 2liter water bottle once a week, my temps will stay below 70 degrees.

I went to the Home Depot and got a few things then on the way home found a new grow shop (called the grow room) it was great because I was going to get everything off amazon (sprayers n timers n junk) but stumbling upon a place tucked in an industrial area I have everything today. Except no one had a 4ft 4"pcv tube so that is tomorrow's quest. Also I've more 1/2" tubing that I'm going to get to complete the stand and plumbing.
Anyway I'm too high on hash and ranting. Stinky ol boy, you're alright,
