I found one 1000 watt MH, and 2 100 watt HPS security lights (like the kind at gas stations) laying around my workshop, and was wondering if i could just use the 1000 mh for the entire grow. Im gonna be growing just a few mandala #1's (100% sativa i believe) with it. OR could I get an HPS bulb that converts for an MH ballast? Ive seen MH bulbs that work in HPS ballasts, but not the other way around. Any help is appreciated
