Do color lights affect plants?
On One Hand: Plants Preferentially Absorb Certain WavelengthsThe chlorophyll and other pigments in plants do absorb some light frequencies better than others. Typically, plants absorb light mostly in the blue and the red ranges in order to perform photosynthesis. Different parts of the plant absorb light differently, and the light has slightly different effects depending on where it is absorbed. Lamps providing a lot of light in the blue and red spectrum will indeed help a plant photosynthesize.On the Other: Plants Need Full-Spectrum LightAlthough blue and red are predominantly used for photosynthesis, they are not the only color bands that a plant absorbs. Plants evolved to live in white light, which contains the entire visible spectrum. They absorb at least some light in all color bands. This may even affect plant nutrient levels.Bottom LinePlants need a wide spectrum of light in order to thrive. Using light as close to natural light as you can get is best. Using only colored lights
