Greenhouse Film Infomation
The total light transmission of the greenhouse film is extremely important for Photosynthetically Active Radiation (P.A.R.)
The PAR range is 400 to 700 nanometers. The intensity of these wavelengths (PAR range) directly influences growth and development of green plants.
Most Thermal Films provide diffused light. Light diffusion increases photosynthetic efficiency by providing more homogeneous light from all directions.
A diffused film reduces shadows, helps minimize burning and ensures better distribution of light.
It has also been known to help average leaf temperatures.
During the day, the greenhouse structure, plants and soil heat up due to both visible and infrared light from the sun. In the evening it cools down and re-emits radiation within the IR range.
Special properties are incorporated within the film which block IR radiation and help maintain a controlled temperature in the greenhouse, providing plant insulation and less cycling of heaters at night.
