220V 3W 4W 5W LED Grow Light E27 Plant Flower Growing Lamp Bulb Indoor Greenhouse For Hydroponic Vegetable System Growth

Less than 400nm: MchlorophyII absorption less, affecting the photoperiod effect, to prevent stem elongation

400-500nm: (Blue) 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) 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 vegs germination
