At GLS, we tailor our LED grow light wavelengths for particular photomorphogenic responses, photoperiodic signals, chlorophyll A and B absorption, xanthophyll carotenoid pigments, and anthocyanin accumulation in plant tissue.  We also design and build our LED modules using a precise mix of LEDs. The white portion of the recipe is composed of a precise ratio of warmer and cooler correlated color temperature (CCT) LEDs. The result is our GLS HI RED spectrum--exceptional for full-cycle cultivation.
