Photoreceptors and Spectral Absorption

A Brief History of LED Grow Lights

Full Spectrum grow lights carry the blue spectrum which stimulates vegetative growth and the yellows, ambers/orange, reds and far-red spectra which stimulates pre-flowering and flowering (reproductive growth). Therefore, virtually all plant life will grow from germination to maturity using JUST LED US LED lights with wavelengths in the ranges of 400 to 730nm that target all four receptors of chlorophyll A and chlorophyll B absorption peaks.
