600 watt mh for veg 1000 watt hps for flower.veg 4 weeks flower 8.yield 1 to 2 pounds.that is every 3 months.you want 3 pounds every month?you need about 3000 watts mh for veg and about 5000 hps for flower and then you will still only get 4 to 6 pounds every 2 months.and if you are running that many lights i hope noone is living there because it is gonna cost your 500-600$every month in power bills alone.sorry if i killed your dream it just isnt that easy.unless you grow outside.if you sell 3 lbs a month then try to grow 50 lbs outside next year.that will take 200 to300 female clones that will finish on time.dry cure store and sell it all year.much cheaper much easier.
