With so many greenhouse plastic options available, you may not need to replace it every year. A simple 4 mil poly greenhouse plastic is only going to last for a year. There are many other options that offer a longer lifespan!

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?

  • When the lifespan has been reached

  • When the plastic is discolored

  • When the plastic is too damaged to repair

  • Consider new plastic if heating or cooling costs are increasing

  • Look for alternatives to removal for winter
