led grow light 2016 epistar chip 0.6M*M/ 0.6m / 120 degrees 54PCS*0.1W Full Spectrum Led Grow Light Bar 8w Plant Tissue lights

 XQD  company  product  more kinds of  LED Grow light ,we also accept customized to the different needs of different plants depending on the wavelength spectrum required for LED plant growth lights for customers.

Principle:

Light environment plant growth and development is one of an important and indispensable factor in the physical environment, through light quality regulation,

control plant morphogenesis is an important technical facility cultivation areas.

Spectral range effects on plant physiology:

1. 280nm ~ 315nm influence on morphological and physiological processes is minimal

2. 315 nm ~ 420nm chlorophyll absorb less influence light cycle effect, prevent stem elongation

3. 420 nm ~ 500nm (Blue) chlorophyll and carotenoids absorb the largest proportion, the greatest impact on photosynthesis

4. 500 nm ~ 620nm pigment 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 is low, stimulation of cell elongation, affect flowering and seed germination

7. > 1000nm converted into heat
