1. Color temperature and lumens of plant lights

The color temperature and lumens of plant lights are seen by human eyes, while the photosynthesis of plants does not look at color temperature and lumens.

2. The effect of spectral range on plant physiology

      280 ~ 315nm——> Minimal effect on morphology and physiological process

      315 ~ 400nm ——> less chlorophyll absorption, affecting the photoperiod effect and preventing stem elongation

      400 ~ 520nm (blue) -> The absorption ratio of chlorophyll and carotenoids is the largest, and the impact on photosynthesis is the greatest

      520 ~ 610nm (green) -> the absorption rate of the pigment is not high

      610 ~ 720nm (red) -> low absorption rate of chlorophyll, has a significant impact on photosynthesis and photoperiod effect

      720 ~ 1000nm ——> low absorption rate, stimulating cell extension, affecting flowering and seed germination

      ＞1000nm ——> Converted into heat
