Nice setup. When I saw all of your tents this is what came to mind.
I have two grow spaces. A closet for a couple autopots and a 3x3 tent that I top feed. I use coco with perlite in both spaces and feed them Jacks. Either 321 or TAP. So, I am pretty far removed from organic growing. However, I used advanced nutrients Iguana organic line for a year +_ and still use many of AN supplements in coco. I also use various microbes (Tribus, Great White, FishSh’t, Voodoo Juice ++) so in that respect I have living COCO.
I think, to get the most out of the autopot system an inert medium like peat or coco is the way to go. Environmentally coco is preferrable.
I have a seat and am set to watch.
I am just getting started on a small grow of Afghan at Afghan to close 2022
