The large surface of grow light panels distributes light over a wide area to grow plants indoors. Their built-in LED arrays emit light in a range of color spectrums that optimize different stages of plant development (seedling growth, stem and leaf growth, and budding and flowering). LEDs use less energy than other lighting technologies and run cool so lights can be placed within inches of plants without causing wilt or burn. The panels suspend from chains or cables to allow adjustment up or down to suit the height of the plants below. They are rated for wet locations to withstand high humidity and resist water sprays. Panels are commonly used as the base component of an installation and supplemented with smaller grow lights to get the necessary coverage. Grow lights are used in greenhouses, hydroponic gardening, vertical farming, farm-to-table and urban farming, agricultural research, and other indoor growth applications.
