We're about to rip each other to pieces down here, but hopefully it doesn't get that out of hand. Sounds like you're firing on all cylinders up there. Have you researched making fish hydrolysate or burying fish is the ground? The natives taught the pilgrims this when they first got over here. I think the reason I can reuse the peat is because I use it like a soilless medium and don't reply on it to retain anything more than roots. After a harvest and chopping the plant right to the ground, I flip the can over a tote, peel off the fabric pot, and poke the root mass a shit load of times with these shelf cuts to loosen the peat from the roots and gently comb and poke as much peat as I can loosen from the roots, and am able to mostly get it down to the main bunch of roots so that what's left behind has minimal roots left in it.
This lock down made certain things harder to locate for me. Perlite was one of those things. Normally I could shoot up to Home Depot that was 3 miles away and grab a 2 cubic foot bag of perlite for $18, now they no longer stock that at my local store and had to order it over the internet. IDK what sized perlite you use, but I don't know how to reclaim my perlite if I needed to, so if my peat ever stopped working, I think I'd probably just throw it all out and start over. Mixing 3 cubic feet of dried peat is no easy task when done n a bedroom, so when I do it, I want it to last for months and months. I wish I was this frugal when I was buying $40 bags of rockwool frequently, though if I could ever go back to hydro, I would probably just use big stone perlite like Tead does. But generally speaking, my grow is fantastic. I use very little electricity and water and all other aspects are paid for. Making nutes and reusing the $25 medium has my only expense to be the utilities and still taking 1 plant every week. I'm even weeding out the GSC and A Purple because they don't yield well and will focus my attention on the cheese, Bulk and PC till I can get another seed order.
ther than that, there's not much to say. Everyday and every week it's the same routine. Take clones, then harvest, take clones then harvest, take clones then harvest. I look forward to your journal update.
Edit - sorry, I forgot to include the pic of the shelf cuts
