Do LED grow light have 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.

Hereof, will UV lights hurt 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.

Considering this, how much UV light does a plant need? Contrary to popular belief, plants do not need ultraviolet (UV) light to grow. Plants require blue and red light, which are not a part of the UV color spectrum. Blue light encourages chlorophyll production, which helps the plants create strong and healthy stems and leaves.

Keeping this in consideration, 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.

Why is my grow light pink?

The larger the ratio, the more pink it appears. Since red wavelengths are the most important for plant growth and plants like a ratio of around 5 to 1 of red to blue light, most LED grow lights actually contain more red than blue diodes. This means that their light is actually more pinkish than purplish.

Why does blue light help plants grow?

Plants photosynthesize nutrients for growth using a green substance in their cells called chlorophyll. Most types of chlorophyll can use the blue spectrum of light more efficiently than the red and far red spectrums of light. … This maximizes the space used and light available for each leaf in the growing area.
