Okay first which is better on a VERY limited income...metal halide or high pressure sodium? Second. How much wattage is nessary..lowest but still able to grow? Im only try to start up 2 plants maybe 4...and I wanna do this so the power bill doesnt sky rocket...Ive never done an indoor grow. My outdoor grow went well all the way up to the drying part...didnt get to correctly dry it and it molded...smoked a lil bit and it was some good smoke but i was kinda weary of smoking mold so i tossed it...and being its winter here in the SE USA...i wanna start another grow soon, but before spring.
