All greenhouses are covered in greenhouse plastic of one kind or another. The kind of greenhouse cover you choose depends on what you are growing and what you are trying to accomplish with the greenhouse film. Pro-Tect Plastics offers a variety of greenhouse plastic film that can accomplish light filtration, complete light deprivation, or temperature and moisture control to suit your needs. Growers across the country have designed greenhouse plastic systems that produce the best yields and harvests in their indoor growing areas. Whether you are a commercial grower or hobbyist, we have the greenhouse plastic sheeting that will work for you.
Heat shrink wrap and black white light deprivation films are commonly used in agriculture applications. Whether you want to form a snug waterproof barrier around your greenhouse to control temperature or need to tightly control grow cycles through light deprivation or reflectivity, heat shrink wrap products from Pro-Tect Plastics can help!
Wrapping a greenhouse in shrink wrap is a common strategy used to extend the growing season of the crops or plants contained within as well as increase the yields each season. Black and white plastic sheeting is also used in crop control management. The white side is highly reflective and used to direct light away. The black side will absorb light, keeping heat and light away. Heat shrink wrap can help control temperatures and humidity levels for improved results.
Greenhouse film will expand and contract as temperatures increase and decrease. Typically, dimensional changes of 1 to 12 inches in length and 1 to 4 inches in width can be expected under field conditions. The actual expansion and contraction will vary with differences in black and white poly film width, gauge, formulation, and manufacturing conditions. Allow for the normal expansion and contraction of the greenhouse blackout film during installation. Single layer greenhouse film should be installed snugly, but should not be overly tight. Double poly film installations should provide enough slack in the top layer to allow 12” to 24” of inflation.
