28W E27 Full Spectrum Led grow lights Led bulb plant lamp Red Blue UV IR for grow tent greenhouse grow lighting

Spectral range effects on plant physiology:

 
280nm ~ 315nm influence on morphological and physiological processes is minimal

315 nm ~ 420nm chlorophyll absorbs less impact photoperiod effect, prevent stem elongation

420 nm ~ 500nm (blue) chlorophyll and carotenoids absorbed the largest proportion, the greatest impact on photosynthesis

500 nm ~ 620nm dye absorption rate is not high

620nm ~ 750nm (red) chlorophyll absorption rate "high", has a significant influence on photosynthesis and photoperiod effect

750nm ~ 1000nm absorption rate, stimulate cell elongation, impact of flowering and seed germination

> 1000nm converted into calorie.
