From the above plant and spectral data, the influence of each wavelength of light on plant photosynthesis is different, among the light required by plants for photosynthesis, 400 ~ 520nm (blue) light, and 610 ~ 720nm (red) contribute the most to photosynthesis, while 520 ~ 610nm (green) light, the efficacy rate of plants to exercise growth is very low.
