I have a 0.9x0.5x1.8m tent (roughly 3' x 1.5' x 6') and I am having a hard time choosing between a 400 watt HPS/MH grow or Mars Hydro Reflector 96 (actual wattage 203 watts) for my first grow. I plan on having 2 or non autoflowering plants growing in soil. I'd be spending extra going with the Mars Hydro Reflector 96, but would it be worth it compared to 250 or 400 watt hps/mh?
