What colour is the plant lamp?
The chlorophyll of photosynthesis in plants, there are two main spectral range of chlorophyll can be absorbed directly, one is in the red part of the wavelength of 640~660nm, the other is a blue violet light wavelength of 430~450nm, in addition to plant xanthophyll and carotene can absorb energy and to carry out photosynthesis chlorophyll, xanthophyll and carotene. The absorption spectral range is about 400~500nm, slightly wider than chlorophyll absorption direct blue violet range, so the plants can all spectral range using the 640~660nm+400~500nm two range, effective spectrum to plant growth light should be red and blue violet, the color should be red or blue purple.
It is better to have the sun's rays. If not, use three primary colors, and the wavelengths of the plants are different
Selective green plants to light is mainly concentrated in the 400460nm blue violet region and 600750nm orange area, containing the two lines on the light in you
