Light emitting diode (LED) is a kind of electrical equipment, which can emit a series of energy-saving light that can stimulate plant growth. The LED grow light works well when planting plants indoors. They are useful for indoor greenhouses because they provide the light needed by indoor plants because indoor plants cannot naturally obtain light from sunlight

LED grow light is an artificial light simulating sunlight, and the light helps plants to carry out photosynthesis. The spectrum of light they emit may be similar to the sun’s or have certain light spectrums that may stimulate plants at different stages of growth. The light source is composed of white LED, blue LED and red LED. For different plants, the proportion of red light and blue light most suitable for their growth is different. We can adjust the ratio of red and blue light through LED grow lights. Plants need different light hours at different growth stages. We control the time by switching LED grow lights.
