28 led LED Plant Grow Light Lamp UV IR bulbs for indoor Full Spectrum greenhouse
how the grow light help plants :
Less than 400nm: MchlorophyII absorption less, affecting the photoperiod effect, to prevent stem elongation
400-500nm: (Blue led light ) High absorption by chorophyII and carotenoids, big influence on photosynthesis
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.
500-600nm: Low absorption by pigments
600-700nm: (Red red light ) ChorophyII absorption rate is low, has a significant effect on photosynthesis and photoperiod effect
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.
More than 700nm: Low absorption rate, stimulate the cell to extend, affecting flowering and seed germination
