Product Details:
<br />Less than 400nm: MchlorophyII absorption less, affecting the photoperiod effect, to prevent stem elongation
<br /> 
<br />400-500nm: (Blue) High absorption by chorophyII and carotenoids, big influence on photosynthesis
<br />Blue Light: For plant growth and absorption. Can enhance chloroplast activity, to prevent spindling plant, But on the other hand, it will inhibition of photosynthesis, so that the plant need much blue light.
<br /> 
<br />500-600nm: Low absorption by pigments
<br /> 
<br />600-700nm: (Red) ChorophyII absorption rate is low, has a significant effect on photosynthesis and photoperiod effect
<br />Red Light: For plant flowering and fruiting，Promote plant growth, germinatiion, flowering, results. The most dominant role during adding color on the plants, accelerate photosynthesis. 
<br /> 
<br />More than 700nm: Low absorption rate, stimulate the cell to extend, affecting flowering and seed germination
<br />
