Some of the amazing products they offer include pollen bags, parts for air duct systems, digital timers, and plant hanging systems. The company also offers a great selection of grow light fixtures and ballasts, both of which are designed for either metal halide (MH) or high-pressure sodium (HPS) grow lights. UltraGROW fixtures come in a diverse range of sizes and designs, from 6-inch to 60-inch hoods, for both small and large spaces. Fixtures can be hung horizontally for maximum coverage or vertically to save space. Bulbs and ballasts are sold separately.
