Can plants live on a light bulb or do they need sunlight?
Question Date: 2016-03-17
Answer 1:

Plants can live on light bulbs, but not as easily for several reasons. First, light bulbs shine at different colors than the sun does, and plants are more used to the range of colors you get from sunlight. Second, light bulbs are rarely as powerful as full sunlight, you need a lot of them. However people do grow plants on electric light.

Answer 2:

Plants can live on light bulbs, if needed, as long as the light bulb provides the full spectrum of light that the sun provides (most incandescent light bulbs do and so do LED lights that are specifically designed for plant growth) and with the right intensity and hours per day.
