Which kind of light is good?
In fact, the light replenishing lamps are basically effective, but we have to choose them well, because the light needed for photosynthesis of plants has a wavelength of about 400 ~ 720nm. 400~520NM (blue) light greenhouse plants perpetual lamp, and 610~720NM (red) contribute to photosynthesis, 20~610NM (green) light, and the ratio of plant pigment absorption is very low. Plant lamps are made of red blue combination, all blue and all red to provide two wavelengths of light. The light source we used is more efficient, and the spectrum is more suitable for the supplementary light of plants. Moreover, the LED lamp has the advantages of low power, high light efficiency, long service life, low power consumption and high safety factor, which greatly reduces the input of agricultural materials.
