Overwinter Poly Film
Overwinter film is designed to protect more sensitive plants from harsh winter conditions. It helps to keep direct freezing wind, snow and ice off from plants and even protects from frosts during the spring and fall. This poly film is typically not as thick as regular greenhouse film but doesn't need to be as it is only for seasonal use. Overwinter poly film is lighter and more economical and because of this can be discarded after each year if necessary without putting the user in debt.
