Grow light kits include fixtures with LED bulbs or built-in arrays to set up a new installation or add onto an existing one. 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. Single-style kits include fixtures of the same style. Multiple-style kits include fixtures of different styles. Grow lights emit light in color spectrums that optimize seedling growth, stem and leaf growth, or budding and flowering to grow plants indoors. They are rated for wet locations to withstand high humidity and resist water sprays. Grow lights are used in greenhouses, hydroponic gardening, vertical farming, farm-to-table and urban farming, agricultural research, and other indoor growth applications.
