Approximately 3% of the light radiation from the sun is ultraviolet; in the range of 100-400 nm. The light is the ratio of 1:30 UVB to UVA, and all UVC is absorbed by the atmosphere, particularly the Ozone layer. UV light rays can damage plants and stress them, triggering the creation of more trichomes.cannabinoids such as THC, CBD, CBG<ref>What light spectrum does weed need to grow? - Growing Cannabis 201: Advanced Grow Tips | Indica Institute - https://www.youtube.com/watch?v=NY0bB_Jmt5E</ref><ref>Pate, David W.
