Yes, if the black light only emits UV-A, and meets the requirement of intensity required by the plant. UV-B will damage the plant's DNA, and UV-C will make ozone also damaging the plant.
No, radishes require sunlight to grow through a process called photosynthesis. Black lights do not provide the necessary spectrum of light for plants to undergo photosynthesis.
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.
they grow biger
Black light tattoos are designed to be visible under ultraviolet light, commonly used in black light. They are usually not visible under normal light unless they contain regular ink as well. The ink used in black light tattoos absorbs and re-emits the ultraviolet light, creating the glowing effect.
Yes, using a grow light can help provide the optimal light conditions for seedlings to grow successfully. It can help prevent issues like leggy seedlings that result from insufficient light exposure. However, if you have a very sunny indoor spot, you may be able to start seeds without a grow light.
It can be.

i don't know get a life freak

Black light contains not nearly as much of the needed light for the plants as the sun does,if you got little access to light where you wanna place them them then you may wanna use grow lights as they are made to produce very much similar light as the sun does,however,there's no light that can replace sunlight 100% if possible then use that... more information about grows under black light in the related links section
she smoked some marijuna
No smoke as much as you want.
There are some rubies, especially Thai, that have too high an iron content to grow under black light. But unless the iron content is too high, rubies glow pinkish-red under a black light.
no he smoked to much marijuna
They don't NEED a light. There a type of fancy goldfish, so you don't need to get them a light. However a light is helpful as it helps them grow and convert vitamin D.
