This 50W LED glow light with the professional spectrum ratio of red:blue=3:1. This is the most suitable ratio for seedling and vegetative stage. As we know, plants do not use the entire spectrum of light.The chlorophyll and carotene only absorb the light at the range of two particular wavelength(blue 460-470nm and red 660-670nm). So we designed this round LED grow light with red and blue light only. As the red light works in the plant budding stages, flowering, fruiting,improve the harvest. The blue light greatly improves the accumulation of proteins and non-carbohydrate,helps plants gain weight. The combination ensures that the plants grow healthy and lush inside of house.
