The map is the entire visible spectrum (Ri Guang), we can see that the band can promote plant growth basic bias in red and blue, which is shown by the green lines covered the area. This is why the Internet called LED bought only by plant growth lamp causes the red and blue beads.Red and blue collocation ratio, 7:1 7:2 7:3 can in fact be, detailed research abroad, every kinds of meat demand are slightly different, but the approximate ratio are similar. This can not too tangled.Why do many people claim that the red and blue plant lights bought on the Internet do not work well? The reason is very simple: the power is not enough. See the first article!Red and blue collocation of plant growth light effectively, the premise is certainly enough power! How much power the specific needs? To tell the truth, do not know, there are few seriously study these fleshy game player data, reference seawater standard calculation, 6 square centimeters of the corresponding 1W (specific data ATS Yi Zhaohai water algae screen lighting standards, the power of LED low illuminance algae algae), good cylinder flower regional one meter square area, 20W adopts LED light red and blue collocation enough.One meter square area, 20W using red and blue with LED lights, which is based on the experience of farming out the most conservative estimates
In fact, had experienced years of fleshy students know, direct high strength sun a few hours a day, the effect is far more than 10 hours a day or more scattering sunlight! So, to fill the effect, the absolute power is an important factor to consider!
With the sea cylinder as an example, a marine biological need light in fact we have more stringent standards, usually require 1L water corresponding to 1W lighting, the 1W is not very scientific, but should be in accordance with the lumens of illumination, such as LED in most cases, the same wattage under illumination will reach about 1.5 times halogen and three primary colors, in order to facilitate description say it. In order to raise the wattage of marine life experience, if not up to this standard, in fact, half of the illumination is not equal to half of the effect, can say: no! So, the so-called internet grow light, you look carefully, find a lot of is the 5050 patch LED (mall jewelry cabinet decoration lamp, single lamp) are not even 1W! Look a large lamp giant luminous area, looks dazzling, actually a lot of time power is only 1~3W! It is conceivable that the effect is limited.
