LED lights and plants, flowers, how many centimeters away from the benefits?
LEDThis saves power, produces very little waste heat, and has a long life. LED planting is absolutely possible, but I don't recommend LED with family support. Although LED can full spectrum, but the full spectrum light distribution is not uniform, if a small area of brachytherapy, for small plants, the spectral distribution is not balanced. And now I haven't found a LED with uvb. LED lamp power, uneven distribution can be used to solve large scale, long distance, but in general a full spectrum of LED is more suitable for factories and planting greenhouse. Meanwhile, the lack of UVB is also more suitable for growing C3 C4 plants. If the separate UVB chip, large area and high strength, can be. But in general, less efficient is less efficient. If the annual plant, regardless of the root development, regardless of shape, red and blue enough, if you consider the root development needs to add orange yellow light, orange light also has a certain underground accumulation.
Three primary colorsFever is not too much, cheap, spectral distribution is not very reasonable, relatively large energy consumption, plant utilization of the luminous utilization rate of less than 70%. The disadvantage of using three primary colors is that the energy consumption is still a little bigger. No 10000LX light intensity can be said to have no effect on desert plants. But the energy required by 10000LX is quite scary. I calculated that it would be about 500 watts per square meter (50CM distance), and it would be uneconomical to use it for a long time.
