LED Grow Light Dual Head 28W Plant Grow Lamp LED Gooseneck desk holder with on/off Switch for Hydroponics Grow System greenhouse
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 germination
Note :
1. Would be better to keep the distance between the light and plant in 20-25cm.
2. Generally this grow light should be turned on for 5-8 hours every day.
