Best Light Spectrum for Plants: Blue, Red, Far-Red, UV, and Full Spectrum Explained
Blue, red, far-red, and UV wavelengths affect plants in different ways. Blue light is closely associated with plant structure and morphology, red light is highly effective for photosynthesis, while far-red and UV can influence plant signaling and responses. The effect of each wavelength depends on its intensity, duration, ratio to other wavelengths, and the plant species.
