Question

Can artificial light grow plants?

Answer

Yes, artificial light can be used to help grow plants.

In more detail, plants need sunlight or an alternative source of light to perform photosynthesis – the process by which they convert sunlight into energy to grow. While natural sunlight is ideal, it's not always possible due to factors such as lack of sunlight, seasonal changes, indoor gardens etc. In these cases, artificial lights like fluorescent lamps, LED lights, high-intensity discharge lamps (HID) etc., can provide the necessary light spectrum that helps stimulate plant growth.
