LED Grow Lights Red and Blue Spectrum is necessary and critical for plants growing. Grow light is essential tool for your plants in colder and darker seasons like autumn & winter. For photosynthesis to occur and chlorophyll to absorb the maximum amount of light for plant growth, plants use both blue and red light most efficiently..
For growth, blue light is essential to help plants produce healthy stems, increased density, and established roots – all which occur in the early vegetative growth stages. Growth then continues with increased red light absorption, resulting in longer stems, increased leaf and fruit/flowering etc. It’s here that red light plays the dominating role in plant maturity and, therefore, size.

Spectral range effects on plant physiology:
1.280nm ~ 315nm influence on morphological and physiological processes is minimal.
2.315 nm ~ 420nm chlorophyll absorbs less impact photoperiod effect, preventing stem elongation.
3.420 nm ~ 500nm (blue) chlorophyll and carotenoids absorbed the largest proportion, the greatest impact on photosynthesis.
4.500 nm ~ 620nm dye absorption rate is not high.
5.620nm ~ 750nm (red) chlorophyll absorption rate "high", has a significant influence on photosynthesis and photoperiod effect.
6.750nm ~ 1000nm absorption rate, stimulate cell elongation, the impact of flowering and seed germination.
