Research on the application of LED grow lights to plant facility cultivation

1. As supplementary lighting for plant photosynthesis when the amount of sunshine is small or the sunshine time is short:

Research on LED as supplementary lighting for plant photosynthesis. Traditional artificial light sources generate too much heat. For example, LED grow lights are used to supplement lighting and hydroponic systems. Air can be recycled, excess heat and water can be removed, and electricity can be used. It is efficiently converted into effective photosynthetic radiation, and finally into plant matter. Studies have shown that the use of LED lighting can increase the growth rate and photosynthesis rate of lettuce by more than 20%, and it is feasible to use LED grow lights in plant factories.
