Photosynthesis requires the availability of UV light. The fact that LED grow lights don’t provide the UV spectrum as readily as other alternatives make them relatively less popular among growers. UV Spectrum LED lights solve this problem by providing the UV spectrum that is lacking in other LED grow lights.

What is Ultraviolet Light (U.V.)?

UV light, simply put, is a type of electromagnetic radiation that generally comes from sunlight. There are three different wavelengths in which UV light is present: UVA: 400nm-315nm, UVB: 315nm-280nm, UVC: 280nm-100nm.

The earth’s atmosphere does not allow UVC to exist on earth naturally. With advancements in technology and the rise in indoor gardening popularity, UV light is now available for growing plants indoors. This is something that wasn’t possible in the past. Some grow lights are equipped with a built-in system to generate UV light, while with others, you will need to install LED UV bars or MH Lamps.

Does a standard grow light emit UV?

Generally, grow lights emit light between the red-blue spectrum. Installing a UV grow light can benefit your plant by increasing photosynthesis, which results in more energy for the plant and an increase in trichome production and overall potency. It is important to remember that the infrared and UV spectrums can be harmful to plants in large doses.

What is the Best Light Spectrum for Growing Plants?

Plants mainly need the blue and red spectrums for the two stages of their lives and generally do not require a lot of UV light for photosynthesis. Given that plants mostly need the blue-red spectrum, it is smart to go with Full spectrum LED grow lights to save yourself the hassle of changing lights back and forth at different stages of the plant’s lifecycle.

What Are the Benefits of using UV light for Growing?

  • Causes more branching, less stretching
  • Increases root mass
  • Increases the speed of the germination process for starting seeds
  • Creates more potent plants
  • Increases resistance to insects, bacteria, and fungus
  • Increases oils & resins
  • Improves taste and smell
  • Reduced plant shock when transferred outdoors
