This entire grow using the Undercurrent System in pioneering in it's tech, but I am very eager to see how you deal with containing these monsters. I see the tomato rack setup on the 1 bucket, but I don't think they will be sufficient, I think you will be taller and wider than those tomato racks provide for. Those are the stock ones from home depot?
My friend special orders some wider ones from home depot for his forest, but you will dwarf him with this setup. I noticed badfish used a lot of hanging ties, like a zillion, but they seemed messy and a lot of work. I just don't know how best to handle your tall branches I expect.
I am wondering if you may run long 2 lengths of PVC down (left and right) of each row of pots (intermediary support along the way). Then you can tie up some (several
botanicare 4x8 or custom or whatever) trellis between the PVC lengths giving the plants something to lean on. You could have like 2 or 3 different height trellis runs going if you need it. This will be a lot less work than those strings badfish used. At harvest, just cut the cheap trellis and leave everything else for the next run.
That's my 2 cents on this Easter Sunday!
