UV light helps plants grow healthier and quicker. It is not required though for most plants to grow and survive.
Black as a color would absorb all visible frequencies of light. A "black light" is not actually black, but rather emits most of its light in the ultraviolet frequencies. This light is invisible to our eyes except that it interacts with certain materials that fluoresce (glow in the dark) when they absorb UV light. These lights are also used for indoor plants that need UV light to grow.
Green plants, most algae and some bacteria need access to sunlight, or a source of broad -spectrum visible and UV light. This is because these organisms derive energy from the light.
UV rays affect vegetables. They alter their chemical composition.
I believe (do not quote me; I'm not sure) that plants do not need direct sunlight. Plants perform photosynthesis, which requires light from the sun to make energy- and I believe that plants need a wider light spectrum than just visible light. Therefore, plants need sunlight or the closest synthetic approximation (for example, fish tank lights often emit UV rays and possibly others in addition to normal light, letting aquatic plants live).
halobacteria produces salt and chloride layer on top which shortens the UV wavelength protecting itself from UV light. that's why they grow fantastically on Mars.
Your plants should still grow if UV rays are blocked.?æ Greenhouse panels are designed to block UV blocking filters, and they grow plants well.

No, I don't believe so. You need UV Light in order to grow plants and the only lighting that gives off those are Florescent lights
== == Several studies have found that UV lights are quite toxic to plants.
you need cannabis seeds and a uv light plus a lot of money for the bill and water

The fluorescent type of light bulbs (correctly called lamps) have a phosphor that besides emitting visible light (400 to 750 nm) also emits some UV enengy in the UV-A range. Plants need visible light and some UV-A to be effective.

Yes. Plant life is known to benefit from UV light. An example is people who grow their own marijuana indoors under UV lights.
