LED plant lighting: the role and characteristics of different wavelengths

The effect of spectral range on plants

280 ~ 315nm:Minimal impact on morphology and physiological processes.

315 ~ 400nm:Less chlorophyll absorption, affecting photoperiod effect and preventing stem elongation.

400 ~ 520nm(blue):Chlorophyll and carotenoids have the highest absorption ratio and have the greatest impact on photosynthesis.

520 ~ 610nm(green):The absorption rate of pigment is not high.

610 ~ 720nm(red):Low chlorophyll absorption rate, which has a significant effect on photosynthesis and photoperiod effects.

720 ~ 1000nm:Low absorption rate, stimulate cell elongation, affect flowering and seed germination.

1000nm:Converting into heat.
