When exploring the types of plastic used in greenhouse coverings, growers often consider options that balance strength, clarity, and durability. Polyethylene is the most popular choice because it offers excellent light transmission and dependable weather resistance. It is available in different thicknesses and formulations to match various climate demands. UV-treated polyethylene is especially valued for its extended lifespan and ability to protect plants from harmful sunlight. Some growers also use reinforced polyethylene for added tear resistance in windy areas. Understanding these types of plastic helps growers choose a covering that supports healthy plant development while maintaining a stable and efficient growing environment.
