I'm doing something like this. Grid of rope over plants, using turnbuckles to tighten it, then running a piece of rounded PVC down middle. Using twine to attach to top runners full of buds and weight, to rope over head. Then when it gets cold or another big rain comes I can throw clear plastic or tarp over top. The PVC WILL bow too so water runs off. 3.5-4.5 days straight work since this happened. Some of what you see in pictures is temporary, but they're back up, and I should know but his weekend if they're going to be ok
