What is the best length to make a hoop out of PVC? I was thinking of making it out of 6 ft length pvc for my greens in a 4 x 4 sq ft bed. That would make it 3 ft in the the center. I wanted to put a hoop on each end. Basically 4 ft apart. Would this work?
Should I use scheduled 40, 600 psi PVC pipe or 200 psi pvc pipe use for lawn irrigation? It's more flexible.
