280 ~ 315nm: minimal impact on morphology and physiological processes
315 ~ 400nm: Less absorption of chlorophyll, affecting photoperiod effect and preventing stem elongation
400 ~ 520nm (blue): The absorption ratio of chlorophyll and carotenoids is the largest, and has the greatest impact on photosynthesis
520 ~ 610nm (green): the absorption rate of the pigment is not high
610 ~ 720nm (red): Low chlorophyll absorption rate, which has a significant impact on photosynthesis and photoperiod effects
720 ~ 1000nm: Low absorption rate, stimulate cell elongation, affect flowering and seed germination
>1000nm: converted into heat
