Out of the illumination required by plants, the red light band (610-720nm) and the blue light bland (400-520nm) are critical for the photosynthesis of green plants. In the light curve comparison chart, the white curve shows the average value of effective photosynthesis of sunlight. When compared with the light curves of OURA, the relative intensities of the red and blue regions are close to the maximum performance of PPFD (Photosynthetic Photon Flux Density), providing plants with the quality of light needed to grow indoors.
