Regular plastic sheeting from a hardware store has no UV-protection in it. If you are measuring plastic for the double layer, you will only need enough plastic to cover from hip board to hip board as the second layer will only need to cover the top of the structure. There are some specialty applications in greenhouses where a plastic that is white on one side and black on the other is used in addition to or instead of clear plastic. It can be used for light deprivation to increase the brix of particular crops or to manipulate flowering periods. Its five layers include IR additives, anti-drip condensate, anti-dust, and high light diffusion, which help create more ideal growing conditions and higher yields. Our 6 Mil Clear Polyethylene Greenhouse Plastic and High Diffusion 6 Mil Open UV Greenhouse Plastic are both types of regular greenhouse plastic.
Most plastics are somewhere between crystal clear and white, with many featuring just a touch of opaqueness. White greenhouse plastics are best suited for those who want very little to no sunlight to transfer onto plants. This is a common way of installing plastic film on large or compact greenhouses. High-end film, such as double-layer film with baffles or insulating bubbles, may require a particular channel system that secures the film without penetrating the plastic. For growing plants that need extra protection from direct sun rays, check out this sunblock shade cloth from Ecty.

DIY systems that rig up black tarps with rope are not very good options because they are labor-intensive to operate and often have light leaks that can damage plants. It is the most expensive option for light dep but is also the highest quality and longest lasting option. External automated light deprivation is a great option because it ensures that tarps are pulled on time, at the same time, every time!
Protecting new seedlings from the elements is easy with A&A Grower Supply’s greenhouse plastic film. Available in various sizes, this film is 6 mils thick and designed to resist tears from high winds and storms. In addition, the tarp features UV blockers and reinforced grommets every 36 inches along its rope-hem edges. Available in seven sizes, this HydraTarp model is both waterproof and rot resistant. Especially due to the double-reinforced corners, this greenhouse tarp offers strong protection against the elements, making it ideal for regions subject to high winds or storms. The greenhouse offers growers a chance to save money by raising seedlings to later transplant to the garden or provides a spot where tropical plants can survive cold seasons while still receiving ample light.
Heat can cause major stress to plants, so you will want to consider a greenhouse kit with passive ventilation from roll-up sides at a minimum. If the heat at your greenhouse site gets especially scorching, mechanical ventilation greenhouse kits will help it stay cooler and reduce the risk of drought stress to plants. Roll-up sides on a greenhouse help cool the greenhouse, but if there is not much wind, you’ll need to move air mechanically with equipment like power intake fans on shutters and exhaust fans. Circulatory fans help keep greenhouse temperatures consistent and prevent stale oxygen depleted air from accumulating.
