Plants use the spectrum of light around them to learn about their environment and decide how to grow. Studies have determined that spectrum influence cannabinoid development and that a fuller spectrum grows a plant with higher cannabinoid and terpene content. Color, flavor, and aroma are also influenced by spectrum. Anthocyanins, which are responsible for the pink, red, purple and blue colors in cannabis, respond to short wavelength light such as blue and UV. As the trends of popular cannabis colors change from purple, to dark green, to pink and red, a programmable spectrum can target these flavonoids to stay competitive.
