for your space you should be using no more then an air cooled 250 watt. your going to get to hot in your area and may burn your plants. you should at least save a foot between your 400 and your colas. your plants will obviously grow to about 3-4 feet without LST or Super cropping. for 2x3, i would save your dough and buy Homebox S first
