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.
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.
We recommend the both swithes be turned on during flowering and fruiting stage. Full Color spectrum variations are one of several related variables that a cultivator will want to control for better quality production. Comzler led grow lights will be a good choice. Welcome to purchase!
