Some grow lights naturally emit UV-A light through a chemical exchange, like HIDs and T5 grow lights. LEDs, on the other hand, can be built with specialized UV-B bulbs or diodes to give them the UV they lack.
Likewise, people ask, are LED grow lights UV?
LEDs typically have a tight spectral peak around the wavelength they are designed for, but even so, they can produce occasional UV photons. 450nm blue LEDs, in particular, can produce around 0.05% UV photons- one out of 2,000 photons they create is in the UV range.
In this manner, can I use a UV light for my plants?
Yes, UV has benefits for plant growth, but it can still cause damage to plants and humans if not used properly. … Exposing plants to that much UV can quickly kill them. Growers should provide their plants with a full quality spectrum which emits the right amount of UV.
Are UV grow lights safe?
Most wavelengths are not harmful. However, LED grow lights that put out ultraviolet light are harmful to your eyes. This includes but isn’t limited to fluorescent LED grow lights, HPS grow lights and metal halide grow lights. … On the flipside, pure red lights aren’t harmful unless at a very high intensity.
What kind of UV light do plants need?
UV-A and UV-B are both good for plants. The benefits of both kinds of ultraviolet light exposure include deeper and richer plant color, increased nutrient content of fruits and vegetables, and a stronger defense against harmful fungus. UV-A is okay in any quantity, but too much UV-B can damage a plant’s DNA.
Can I use any blue and red LED light to grow plants?
Blue promotes root development and strong, stocky plant growth. When you blast your young plants with blue, you prepare them to sustain a ton of buds in the future. Red light, on the other hand, does its best work in the flowering phase. A higher intensity of red promotes a higher yield.
Are purple LED lights good for plants?
HIDs shower plants with every wavelength possible, but purple LED lights isolate the specific blue and red wavelengths of light that benefit your plant. This is great for plants because it provides exactly what the plants need to grow and thrive, and it avoids giving them excess light that they’ll waste.
