Do grow lights need UV?
The answer is Yes. Plants don’t require UV light to photosynthesize their food. The reason is that UV light falls within the electromagnetic spectrum which is outside the visible or photosynthetic active radiation band.
Is too much UV light bad for plants?
If a UV light is too strong or positioned too close to your plants you’ll harm them. Exposure to too much UV will result in bleaching of your plants. Bleaching occurs when a plant’s cells are given too much light and they become damaged and discolored, and overexposure to a UV wavelength makes things that much worse.
What UV light is best for plants?
When it comes to the full UV light spectrum, it’s best to stick with UV-A and UV-B varieties for your plants. As mentioned, there is no benefit of direct UV-C exposure to yourself or to your crop (although UV-C may help sterilize your grow room).
Can you get vitamin D from LED lights?
Ultraviolet B Light Emitting Diodes (LEDs) Are More Efficient and Effective in Producing Vitamin D3 in Human Skin Compared to Natural Sunlight.
Can you use LED lights to grow plants?
Offering low energy usage, low heat, and color optimized for growth, LED lights are the most efficient, effective, and customer-friendly way to grow plants at home than growing with fluorescent lights or incandescent lights.
Do you need UV light to grow plants?
While UVC is not naturally present on Earth due to our atmosphere, UVA and UVB are both a key part of life on Earth. Your plants don’t always need to be outdoors to benefit from UV light, however.
What kind of light does a plant need?
Most modern grow lights include a couple of bulbs dedicated to UV lights and IR lights. In order to understand the role played by UV lights for plants, you need to understand what ‘light’ as we know it is composed of.
What should you not do with UV light?
What NOT to do with UV Light! Yes, UV has benefits for plant growth, but it can still cause damage to plants and humans if not used properly. Do not expect to enhance your plant growth by going out and purchasing a sun tanning lamp. Sun tanning lamps provide a lot of UV and human skin can only be exposed to them for short periods of time.
What is the wavelength of UV light for plants?
The visible spectrum of light falls between 400 nm to 700 nm. Just outside the violet end of the spectrum begins the ultraviolet category, with a wavelength from 10 nm to 400 nm. While the human eye can’t pick up these wavelengths, many other creatures, including plants, use it to survive.
