Why do plants need UV light?
Ultraviolet light helps plants produce resin, which increases flavonoids and terpenes in your plants. Flavonoids are responsible for giving certain plants their rich, vibrant colors, while terpenes give plants their taste and smell.#N#When an intense UV wavelength hits a plant, the plant responds by producing a substance called resin. Resin is a protective substance that keeps plants from losing water or being harmed by infection, insects, or other factors that threaten their health like fungi.#N#Increased Flavor & Aroma — When resin’s secreted it brings out flavonoids and terpenes, and that means a richer smelling and better tasting yield come harvest time. That’s why if you give you plants UV you can force them to create more resins and unlock richer flavors.#N#Increased Protection Against Pests — Ultraviolet light will increase resin which means increased protection against pests and diseases. When your plants aren’t being chomped on by pests or trying to heal themselves from a foriegn illness, they’re on their way to dream harvests.#N#Increased Root Production — UV light can reach roots, and limited exposure also helps increase root mass. This will help with it comes time to move plants into more intense lighting, or from moving indoors to outdoors (and vice versa). They won’t need to build a better root system when they’re planted in a foreign setting, which increases their ability to thrive.
What is UV A light?
