Attis 7 LED Grow Light 240w Blended Spectrum.. Signs of Wear and tear very powerful led grow light. For professional horticultural and hobbyist. NEW ATTIS 7 GIMBAL HEADED GROW LIGHT - DESIGNED FOR THE HORTICULTURAL MARKET. 7 Individual Heads with 18 x 3W Chips.RED SPECTRUM affects the flowering and fruiting stages with increased number of buds and overall larger yield. Red wavelengths have the highest quantum yield, whereas blue light is 25 to 35% less efficient in driving photosynthesis (Bugbee, 1994). Blue light is absorbed not only by chlorophyll, but also by carotenoids. Carotenes do not transfer the absorbed energy efficiently to chlorophyll and thus some part of absorbed blue light is not used in photosynthesis. On the other hand, all red light is absorbed by chlorophylls and used effectively. BLUE SPECTRUM affects vegetative growth during early stages to produce thick, stocky plants. Blue light is important for the growth of many plants, including lettuce, spinach, wheat and radish.
It affects the chlorophyll formation; photosynthesis processes, stomata opening and through the cryptochrome and photochromic system, raises the photomorphogenetic response. Blue light (460 nm) promotes dry matter production and inhibits cell elongation in stems and leaves. The optimal flux of blue light for leafy plants is about 10-15% of the total PAR.
The higher flux of blue light is essential for normal carbohydrate metabolism and transportation from leaves to storage organs assuring tuber formation. It also has a slight effect on primary and secondary metabolite synthesis, indicating light-dependent metabolism. Yellow and green light is more efficiently transmitted through the plant body and acts as a signal to tissues not directly exposed to the light environment. Therefore supplemental yellow and green light enhances biomass accumulation in the above-ground part of the plants and also affects chlorophyll and carotenoid synthesis, thus improving the colour of leaves. Phytochromes principally thought of as red/far-red reversible pigments, are extremely sensitive to the entire illumination spectrum and even small variations in the spectrum initiate responses in the photochromic system.
