I made one with 3/4" PVC that I've used 2-1/2 years. I had a bunch of 4' pieces and buckets of tees, crosses, and 45s. I just started putting pieces and fittings together until it started looking like a greenhouse. I ran 1/2" EMT (metal conduit) inside the PVC pipe at the corners and then drove it into the ground. It kept it anchored and added some strength. I covered it with plastic sheeting using 2x4s to hold the plastic on the ground.
