Abstract
The invention relates to a light-diffusing material, having a high transmission of UVA light, useful for horticultural lighting. The light-diffusing material has a hiding power of greater than 50% at 350 nm and a transmission of light at 350 nm of at least 30 percent, and preferably at least 50%. Additionally the light-diffusing material also transmits and diffuses at least 50% of light at 300 nm, 465 nm, and at 800 nm. The light-diffusing material is especially useful as a glazing for horticultural use.
