Just asked you a question on my thread budolskie so I thought is share it here too.
I was saying that I'm not a fan if cooltubes and much prefer air cooled hoods.
But about you finding your way with perpetual, have you thought about a SOG setup with 2 trays of clones sitting in small pots.
Put some in to flower on a 9 week schedule (if you have any 9 weekers) then put a new tray of clones in after around 4.5 weeks. Harvest a tray every 4.5 weeks after that.
Should see you right for 200-300g every 4.5 weeks.
Maybe around 10-15 rooted clones thrown straight to flower after rooting in 5L pots.
So that full you area would consist of 20-30 clones with that 4.5week gap between them. Then each clone only needs to net 10g a piece dry and your golden.
