I made mine from 1” sch 40 pvc.  Have it hung from frame of the tent and height can be adjusted if needed.  Using the white string trellis from Home Depot.  Have got two runs out of one net so far.  Use green coated wire to secure branches where I want after fishing them thru the trellis.  I really feel the scrog let’s me see what’s going on much better than when I let them grow naturally.  I’m still learning a bunch so hope you enjoy!
