Greenhouse12.0Excellent blog detailing the construction of a PVC greenhouse – Adami writes “I have 270 feet of PVC pipe, about 50 pipe fittings (elbows, tees, crosses) for the joints, metals screws, some wire ties, and PVC pipe glue ready to go. The goal is to have a sturdy structure, that is light weight, as air-tight as possible, that can be broken down in the spring and stored behind the fence.” Link.
