Closet grow???

I have a 8x6 closet and want to grow eight to ten indicas. My concern is the best lighting to feed eight plants? Im a rookie at this so any advice is appreciated thanks.

tfor veg state : 50 watt per plant is enough and about 2500 lumens per sq/2 is good. now for flowering you wanan get at least 80 watts per plant and be givig them 10000 lumens per sq/2

Im thinking of going 400 watt mh/hps for veg and flowering.I may drop down on the number of plants.My only concern is temp control. Thanks for the advice.
