Getting your greenhouse dialed in and producing at full capacity can be quite an undertaking. With so many factors to consider regarding what’s going on inside, it’s important to remember that what’s on the outside matters too. We are here to help you get the right greenhouse cover to maximize yields and keep you producing at full potential.

You will notice two different ratings next to each cover description. The first rating is the light transmission rating, which is a measure of how much light can reach your plants through the cover without being obscured or reflected. As a general rule, thin stock like 6 mil will allow for more light transmission and heat retention than thicker stocks.

The second rating is for its diffusion, which is a measure of how much light is scattered or spread out. Diffused light is more effective at penetrating deep into the canopy and is evenly distributed as opposed to hitting only the tops of your plants. This results in increased photosynthetic productivity in the entire plant, maximizing yields.

Ginegar Plastics: 6 Mil Clear Non-woven Greenhouse Poly

Left Coast Wholesale offers Custom-Cut Clear Greenhouse Poly in 6 mil non-woven styles with 90% light transmission and with three different rates of diffusion: 25%, 62%, and 65%. Although the 6 mil is thin, it is made of durable polyethylene resin, which allows optimum light transmission for ideal plant growth. The light diffusion properties help to maintain the optimum greenhouse environment for your grow and help reduce heat loss. 6 Mil Clear Poly is recommended for moderate climates where cultivators need to take full advantage of available sunlight.

6 Mil Clear Poly is also available with an anti-condensate (AC) coating with 85% light transmission and 65% diffusion. The anti-condensation coating prevents condensation from adhering to or gathering on your poly, which can create hot-spots in your greenhouse resulting in uneven growth.
