Also known as agricultural lights, these lights encourage growth in herbs, flowers, and other plants indoors. They have three color settings to optimize your plants’ development from seedling onward. Blue light in the early stages enhances photosynthesis and establishes strong roots. White light during the vegetative stages makes it easier to see the plants and monitor growth. Red light in the later stages supports flowering and fruiting. Easily switch between each color or combine colors when you have plants at different stages. ETL listed for use in damp locations, these lights withstand humidity and moisture. You can link multiple lights together in a circuit to simplify wiring.
