I have been thinking about something like that. Elastic netting is a bit fussy. Deployment of and working around a rigid structure could have both advantages and disadvantages.
Finally got my scrog trimmed out a bit, haven't done this in a while.
Lots of petite sticky sativa buds.
The bungee nets bulge upward mounted with just 4 hooks. Sometimes you have to reposition it a few days later.
You can run it thru the tent spreader bars ( I didn't) to help reduce bulge and make it stiffer.
I have mine woven through the sidebars. It still mostly stretches around the perimeter, leaving smaller squares in the center. Annoying And it does bulge upward a bit.
I waited 10 days into flower when most stretching was complete. Then I broke the mains so they were the same height as the secondary. That was October 6.
When I SCROG, I do weave to lock the parcel twine (zero elasticity) and rigid frame to the hardened branches. After 2+ months in VEG, some of those early weavers have turned to wood. Then the plant and frame are moved as a whole unit.
Figured out why all the blotchy leaves - the space heater slipped a while ago and was pointing more towards the root mass and not the canopy. This is the 2nd crop that did that and I analyzed the wrong symptoms. Thinking feed - D'OH! That has been resolved 4 days ago and the heater blows across the top again. The new growth is the proper green - welcome back ladies.
