If you really do not want to deal with replacing greenhouse plastics, Twin Wall Poly-Carbonate Panels can be used to reduce the amount of plastic needed. The cost of these panels makes them impractical for covering an entire greenhouse, but they are a great material for end walls that will also help insulate the greenhouse if it needs to be heated.
When to Remove Greenhouse Plastics?
