A plant grow light is a specialized artificial lighting system designed to support plant growth by providing the necessary light spectrum for photosynthesis. These lights come in various types, including LED, fluorescent, and HID, each offering different benefits for different plant needs. Grow lights are essential for indoor gardening, hydroponics, seed starting, and supplementing natural sunlight in low-light environments. They help promote healthy growth, improve yield, and extend growing seasons by mimicking the sun’s natural light spectrum.
