Plants that receive plenty of blue light grow with strong, healthy stems and leaves. This process is called photomorphogenesis.RED LIGHTcontributes to the optimal development. It"'"s essential to a plant"'"s early life for seed germination, root growth, and bulb development. It also makes the plant yield better results when flowering.Spectral range effects on plant physiology:280nm ~ 315nm influence on morphological and physiological processes is minimal315 nm ~ 420nm chlorophyll absorbs less impact photoperiod effect, prevent stem elongation420 nm ~ 500nm (blue) chlorophyll and carotenoids absorbed the largest proportion, the greatest impact on photosynthesis500 nm ~ 620nm dye absorption rate is not high620nm ~ 750nm (red) chlorophyll absorption rate "high", has a significant influence on photosynthesis and photoperiod effect750nm ~ 1000nm absorption rate, stimulate cell elongation, impact of flowering and seed germination< 1000nm converted into calorieApplication:Perfect for small Grow Box,Grow Tent,DIY Hydroponics,Bonsai,Garden... et
