Um i grow 12/12 from seed under a 150w 12 plants man and i average 1-2oz per plant so yes you could but all depending on your growing style they will need to be LST'd and kept short also i would advice getting some clamp work lights and throwing 6500K cfls on the side of the 150 cuz they will out grow the light footprint but i vegged a single for 3 months under my 150. Its all in how you use the light my man just got to stuff them in the footprint and you'll be fine.
