Why Use UV?
Research shows UV Light may increase trichome density, desired compound content, flavonoids and inhibit mold and fungal development. Outdoors, about 10% of the sun’s light is ultraviolet. When UV light hits a leaf, the plant makes “sunscreen” to protect itself from damage. Plants produce many different types of sunscreen. Some of these sunscreens are physical, like trichomes, and some of them are chemical, like anthocyanins and beta-carotene. They protect the plant by reflecting away the harmful UV rays.
UV, specifically UVB is known to damage protein and nucleic acids in plant cells, causing decreased metabolism and decreased number of flowers. Therefore, much of the research recommends adding UV at the end of flowering. Research shows that applying UV light for 6 hours per day, at the end of flowering can increases Δ9 content by 28%!
Aside from increasing desired compound content, UV wavelengths can change the color, flavor, and smell of a plant. These changes in color, flavor, and smell often make plants more appealing to humans, but more toxic to some insects therefore plants with increased levels of these flavor/smell compounds are less likely to get eaten by insects! Lastly, there is strong evidence that UV wavelengths light prevents the spread and severity of fungal spores. Ultraviolet light is useful for more than just increasing compound content!
