Solar radiation is a necessary factor for plant growth in addition to nutrition and water. Adequate lighting not only allows them to grow healthy, but also make them colorful, but each grower knows that sunlight is beyond control. Artificial daylight is therefore increasingly recognized in horticultural cultivation because artificial daylight can artificially control the season of plant growth and shorten the time of plant growth. LED as supplementary light, at any time of the day can enhance the light, so as to always help plant photosynthesis. Especially in the winter months, which can extend the effective lighting time. Whether at dusk or at night, can effectively extend and scientifically control the light required for plants, without any environmental changes.
