What plastic is best for greenhouses?
Greenhouse plastics: Polyethylene (PE) Polyethylene is the most widely used option due to its versatility and affordable price. It is sold in single-layer or multi-layer (co-extruded) films with additives that improve UV stability, tear resistance, and light diffusion. The typical thickness range for greenhouse plastic is 4 to 8 mils. Thinner 3-4 mil plastic works for short-term structures. Thicker 8-12 mil plastic provides maximum durability. For full-season greenhouses in moderate climates, 6 mil plastic is often the recommended thickness for good performance.Polycarbonate does have the added benefit of being UV-resistant. What gauge plastic do you need for a greenhouse? Greenhouse covers are typically offered in a range from 3 mil – 12 mil, with the most common greenhouse cover thickness being 6 mil.Greenhouse plastics: Polyethylene (PE) Polyethylene is the most widely used option due to its versatility and affordable price. It is sold in single-layer or multi-layer (co-extruded) films with additives that improve UV stability, tear resistance, and light diffusion.The thickness of your greenhouse plastic plays a significant role in its durability, light transmission, and insulation properties. A thickness of at least 6 mil is recommended for most greenhouse applications, as it provides a good balance between strength, longevity, and light transmission.
What thickness of plastic is best for a greenhouse?

For full-season greenhouses in moderate climates, 6 mil plastic is often the recommended thickness for good performance. The standard greenhouse glass thickness is 3mm, yet with acrylic panels, the thicker the panel, the more rigid it is. The cheapest option is 2mm in thickness, whereas the strongest panels are 4mm.Are 4mm polycarbonate sheets suitable for replacing glass greenhouse panels? Yes. Both 4mm twinwall and solid polycarbonate sheets are commonly used as a replacement for glass. They are significantly stronger, lighter and safer than glass.
Why shouldn’t you grow tomatoes in a greenhouse?
Fungal, bacterial, and viral diseases such as late blight, fusarium wilt, and tomato mosaic virus can quickly spread in the enclosed environment of a greenhouse. By shielding your garden from the unpredictable outside world, greenhouses ensure that each plant gets exactly what it needs to flourish. This tailored care creates an environment where plants can grow healthier, lusher, and more productive than their outdoor counterparts.
