@HappyHydroGrower I think has a variant that is pretty cool too.
I built a frame that has four legs about the distance apart to fit a 7 gallon fabric pot filled with media. It’s all made from Schedule 40, 3/4" PVC and one length of Schedule 20, 1" PVC for sliding legs. The screen is rectangular to make it easier to thread branches through and still work as a SCROG. I drilled holes in the PVC and threaded it through and laced in so didn’t need glue or fasteners. I did add screws to any point that was load-bearing if I picked it up. That way when it’s a pig I can get my wife to help me move it around. Screen dimension is 22" X 30". This allows for airflow and mechanical stuff in the grow space.
My last SCROG gave me 402 grams of flower from one plant. That can be found here:
