In greenhouses, light conversion films can be used to adjust the light spectrum for optimal plant growth, potentially increasing yields and improving fruit quality.  Light conversion film is a specialized material designed to alter the spectrum of light, often by converting one wavelength to another. It manipulates light by changing its wavelength, typically by converting shorter wavelengths (like ultraviolet or blue) into longer ones (like green or red).

The light conversion agricultural films contain special selected additives and pigments to modify the light spectrum entering the greenhouse, thus changing the growth behavior of plants.
