Plant growth lamps are artificial light sources, usually electric light sources, designed to stimulate plant growth by emitting electromagnetic spectrum suitable for photosynthesis.
For example, in winter, when the sun's exposure time may not be sufficient to reach the length of time required for the plant to grow, the light is used to extend the time the plant receives light. If the plant does not get enough light, it will wither.
Use plant growth lights, choose the right spectrum, set the irradiation time, and help your plant to supplement the light source to thrive.
