Well, cattle panels are kinda heavy, ao the trellis is probably the way for you to go to save your body some pain. I did look at those trellises the other day in person. The hinge is just a piece of plastic about the thickness of the lids on store bought potato salad.
I want one more cattle panel, but I need to cut down some ligustrums that have turned into trees first as they will block the morning sun.
I have two panels, with rebar stakes on the outside to hold them, and about 19" between the cattle panels, and that allows room for the 10 & 15 gallon smart plants between them. Also, I want to put trellis up the back end of them so it can be tromboncino cucczza mania, and also make a nice shady spot for cats.
When I looked at cattle panels at TSC online, there was no product weight.
I can cut down 2 x 4’s into slats and uprights for trellises, making them very cheap to build. Also, I would not use hinges, I would just make wedges from wood to keep them at a certain angle. Making wooden pyramids is another option. I need to cut some mater stakes anyway, so just a little more saw work.
