400 Watt HPS Grow Light sets for the novice, advanced and professional grower.
HPS grow lights or high pressure sodium have long been a favorite of hobby and professional growers alike. It is often said to be the perfect grow light for indoor growing as it can be used for both the vegetative and flowering phases of the plant. The light spectrum of HPS lamps corresponds almost perfectly to the light spectrum of the sun. Due to the high level of red spectrum in the HPS light, it plays a critical role in triggering maximum bloom in flowering plants. All our systems come complete with the HPS lamp, grow reflector and ballast, so you can get started right away!
