How thick should a greenhouse film be? For most applications, a 6 mil thickness is ideal. It offers a good balance between durability and light transmission. 2. How long does greenhouse plastic last? High-quality, UV-resistant greenhouse films typically last 3 to 5 years. Overwintering films are designed for 1-season use. 3. Is clear or white plastic better for greenhouses?
