40W Full Spectrum LED Grow Light Bulbs E26 4 Pack, Grow Lamp Plant Light for Hydroponics Greenhouse Organic Indoor Plants

• FULL SPECTRUM --- 24 Red+8 Blue+2 Daylight+2 Warm White+2 UV+2 IR, provide more efficient wavelengths of light to enhance photosynthesis performance hence improving plants' healthy growing. Add extra sunlight to the plants, stipulate the photosynthesis; help shorten the growth cycle.

The effect of spectral range on plant physiology:
280nm~315nm has minimal effect on morphology and physiological processes
Chlorophyll at 315 nm to 420 nm absorbs less photoperiod effect and prevents stem elongation
The absorption ratio of chlorophyll and carotenoids from 420 nm to 500 nm (blue) is the largest and has the greatest impact on photosynthesis
500 nm~620nm dye absorption rate is not high
The absorption rate of chlorophyll from 620nm to 750nm (red) is "very high", which has a significant impact on photosynthesis and photoperiod effects
750nm~1000nm absorption rate, stimulate cell elongation, affect flowering and seed germination
> 1000nm converted to calories
