oh ok... my DWC grows have always been scrog so i never had any such problems.

however, in the future i would like to do a SOG, DWC setup with 4-6 plants per tub.

with 12/12 from rooting how tall do you expect them to get? i was kinda thinking of doing the same in the future and assumed i would be able to keep their height under 18-24 inches...
