Obviously you know how to grow. I never have tried nft, might one day out door, but I imagine it will be full of water, instead of the small stream they usually do.
As to your system, im assuming you run a chiller and use peroxide or h202? Regardless id be painting it all black. The standard white pvc leaks light through it and promotes root rot. Same goes with light blasting through netpots early on. None of this matters as much if your transplanting with a decent canopy that covers it all. Yet preventing light from entering anywhere is one of my main focuses, that and unnecessary drilling. The black tubing for your return line overtime will have a biofilm buildup on the inside, regardless of light, seems they like rubber tubing. I only mention it to as to root matter and perhaps a pebble could get down in there and clog everything. Other than that it looks good man, your drip setup is interesting, but ive never done drip so they are all interesting.
I see this treating you very well, looks pretty diverse. Im sure you could easily turn it into a rdwc if you ever wanted to try it, or even aero. . . Im assuming those are 6 inch netpots, so the tubing is what 7x7? As long as you keep your veg times down I wouldnt think you would have an issue with roots clogging the return lines. Mine can easily get over 2ft long.
But yea, glad to see people putting in the work to see what best fits them. Im on my 4th system now lol. . I enjoy it though so thats all that matters. Learning will occor
