After repeated tests, the light of various wavelengths of LED grow lights is suitable for the needs of different stages of plants, such as seedlings, growth, flowering, fruiting, and maturity. Generally, indoor plants have a short flowering period and wither quickly. The main reason is the lack of light irradiation. The LED light irradiation suitable for plants can not only promote their growth, but also prolong the flowering period and improve the quality of flowers. The application of this high-efficiency light source system to agricultural production in greenhouses, greenhouses and other facilities can, on the one hand, solve the drawbacks that lack of sunlight leads to the decrease in the taste of vegetables in greenhouses such as tomatoes and cucumbers, and on the other hand, it can also make fruits and vegetables in greenhouses ahead of schedule in winter. It will be listed before and after the Spring Festival, so as to achieve the purpose of off-season cultivation.

1. As a supplementary light, the light can be enhanced at any time of the day, which can prolong the effective irradiation time.

2. Whether at dusk or night, it can effectively extend and scientifically control the light required by plants.

3. In the greenhouse or plant laboratory, it can completely replace natural light and promote plant growth.
