One option for this product is a film, a polymer which has the ability to absorb wave far-infrared optical spectrum. It is conducive to the creation of a space podplenochnom optimal temperature conditions precluding both overheating and overcooling of plants. Light-transforming film There are single-layer – a bluish or reddish color, and three-layer (with the effect of the bubbles), two-color (red on one side, on the other – in blue). The advantages of such products should include increased Durability – life can be up to four seasons. Colored light-transforming the film – a novelty on our market. Their distinguishing feature – a special additive, which convert solar radiation spectrum (Ultraviolet radiation becomes useful plants infrared).
This coating helps to intensify the process of photosynthesis, growth of plants, protection from frost and heat. For different regions suit different types of light-transforming films. The film, intended for southern regions, should be protected from excessive UV radiation and consist of an increased content of UV converters. In his time, the "northern option" of the film contains phosphors that enhance indirect lighting. Under such a film even on a cloudy day is enough light for good plant growth. Light-transforming films are used as well as their conventional counterparts. They cover the greenhouses, pull on the arc, shelter beds. Air bubble film consists of three layers of polyethylene food, the total thickness is less than 150 microns, which provides sufficient light transmittance of the film. Between the layers is hermetically sealed bubble of dry air, thus achieving the effect of air blankets, and accordingly – high heat shield (20-30 times higher than that monolayer covering materials).
