Veg: For seedling growth, for the plants in germination or beginning to leaf stage, contains blue and white leds (430-660nm) Blue light is essential during a plant’s germination phase. Stronger concentrations of blue light will encourage sprouting and development of strong roots. Bloom: For the plant in flowering and fruiting stage and contains red and white leds (430-740nm) Red light impacts plant growth in several ways, certain specific red wavelengths will increase the production of a hormone in a plant’s vegetation that prevents the breakdown of chlorophyll.
