One meter power of plant growth lamp
Plant lights have little to do with wattage, mainly color temperature, color temperature, and photosynthesisPlants need light for photosynthesis, with wavelengths ranging from 400 to 720nm. 400 ~ 520nm (blue) light and 610 ~ 720nm (red) contribute most to photosynthesis. 520 ~ 610nm (green) light, the rate of absorption by plant pigments is very low.
1 in accordance with the above principle, the plants are basically made of red and blue light blue and red combination, all three forms, in order to provide two red and blue wavelengths, covering the wavelength range for photosynthesis. In the visual effect, the combination of red and blue lights appear pink.2, white light LED lights, the most common is the use of blue core, to stimulate the yellow phosphor, which combine to produce a visual white light effect.
For energy distribution, there are two peaks in the blue region of 445nm and the yellow green region of 550nm. The 610 to 720nm red needed by plants is very scarce. This explains why plants grow poorly under white light LED radiation.3, the proportion of red and blue lights in plant lamps is generally between 5:1 and 10:1, and the ratio of 7 to 8:1 is usually optional. Of course, conditional, according to plant growth cycle adjustment, red and blue light ratio is best.4 plant light for plant growth, leaf general distance height of 0.5 ~ 1 meters.For example, other control signals or how much I do not know, when you buy consulting expert wow, you use LED lamps this high cost, you kind of is not the ordinary Chinese cabbage, it is best to give you the design experts,
