No. Plants don't absorb much UV. Grow lights are designed to emit light in the wavelengths that plants absorb, so get a grow light.
What does the visible spectrum have to do with plants?
Plants must have light to grow and survive in their environment. The plants specifically use light to make their food in a process called photosynthesis. The light is absorbed by the green pigment chlorophyll, which is located in the leaves of the plant. The actual colors in the visible spectrum that the plant absorbs and uses for photosynthesis are red and blue. The plant reflects green light, and that is what we see when we look at a green plant. Green light is not the only reflected light. For instance, far-red light is also reflected. Far-red is just outside the visible light spectrum. It is not visible to the human eye, but can be sensed by the plant. Far-red wavelengths are important to the plant because of the competition factor in nature. A plant can "SEE" when there are other plants close by because of the increase of far-red wavelengths the other plants reflect. This will then signal the plant to make the necessary adjustments within their system to try to outgrow the others around them since they are competing for sunlight and other resources.

No. Photosynthesis occurs through the excitement of electrons in chlorophyll to higher energy levels. This cannot occur without the correct wavelength of light. Blacklight has only a few limited wavelengths in it, whereas sunlight has all wavelengths of light in it.

hmmmmm nope coz sunlight has different wavelenghts of light which a plant absorbs selectively whereas the blacklight has no wavelengths..

Yes if you want to grow pot! Use a solar light if you want to grow plants but makesure your plant species can handle direct sunlight.

no coz plants need light .....sunlight can be substituted by other artificial bright lights

No because they need a bright light.

No, don't think it's possible, 'cause these lights don't have the UVA/UVB...
