What is UV (Ultraviolet) Light?
UV light is radiant energy that features very short wavelengths (between 100 and 400 nm). UV light falls outside the visible light spectrum. It can be further broken down into UVA, UVB, and UVC radiation.
Do Plants Use UV Light?
Plants do not need UV light for photosynthesis. However, many indoor growers choose LED grow light fixtures that include UV light. This is because UV rays present a threat to plants, so the crop responds by producing more resin. This can enhance the flavor and chemical profile of the product.
