☞☞Specification ☞ 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 ☞500-600nm: Low absorption by pigments ☞600-700nm: (Red led light ) ChorophyII absorption rate is low, has a significant effect on photosynthesis and photoperiod effect For plant flowering and fruiting,Promote plant growth, germinatiion, flowering, results. The most dominant role during adding color on the plants, accelerate 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. ☞ ☞ Note : ☞Please allow 1-2cm error due to manual measurement. ☞ Pls make sure you do not mind before you bid. ☞The colors may have different as the difference display,pls understand. ☞If you have any problems, please contact us before open the dispute or give negative feedback,we will try our best to help you,thank you! ☞ ☞ About Dirance: Our Business - Dirance is a comprehensive store mainly focus on Apperal, Toys And Home &Garden.More information welcome to Click Dirance. ☞ Our Vision - What you need is What I have. ☞ Our Price - We can not make sure our price is the lowest, what is sure is that it is based on the item quality. ☞ Our Logistics - In general, you can receive your lovely item during 7-14 days for product above 5 dollars and 15-28 days for the product under 5 dollars. ☞ Our Service - Just Buy it, Any quality problem we will resend u new one or give u a full refund soon after photo confirmation.
