400w Grow Light Kits

400 Watt High Pressure Sodium (HPS) Grow Lights are sometimes called the "hobby growers light". They pack enough punch to grow quality hydroponic produce but without sending your electricity bill soaring. 400w hydroponic grow lights are usually used to cover a 1m x 1m area (100cm x 100cm). Choose a kit made up from our most popular reflectors, lamps and magnetic or digital ballasts and get growing!
