HPS Grow Lights or high pressure sodium have been the long time favorite of hobbyist and professional growers alike. It's often said that it's the perfect marijuana grow light for it's ability to be used for both the vegetative and flowering stage of the marijuana plant. The light spectrum coming from hps bulbs are a near perfect match to the light spectrum of the sun. Due to the high degree of red spectrum in the HPS light, it plays a critical role in triggering for maximum flower in flowering plants such as marijuana. All of our systems come complete with the hps bulb, grow reflector and digital ballast so you can get up and running right away!
