ECO Farm ECOM 30W UV & IR Supplemental Grow Light Bar
Including ultraviolet (UV) as well as infrared (IR) and far-red waves. These wavelengths don’t factor significantly into photosynthetic rates, but they do affect plants, and in some very interesting ways. It’s important to note that UV and IR lights should generally be operated independently from primary lights, and run for short intervals in your garden.

UV grow lights can also produce changes/increases in phenolic compounds, flavonoid pigments, resins and oil production, etc. As plants are exposed to UV light, they produce such compounds to protect themselves, similar to the way you might put sunscreen on so you don’t get sunburn. While these effects are highly desirable for many crops.

The far-red frequency will encourage young plants to develop larger leaves and will also affect the photoperiodism (Flowering phase) of short-day plants. When short-day plants are exposed to far-red light, it will encourage them to flower. So, many growers will use far-red lights like a 730nm LED light bar for a few minutes up to two hours before the lights off phase. Doing this will speed up flowering, meaning you will see flowers develop quicker than without far red light.
