since im talin taken seeds threw full term an germing all of them an with proper veg time he will end up with niced sized plants...he could get a degi ballest which has the light output close to a 400...hps/mh dont matter...the benifits of using this light mostly would be for canopy penitration/bud production...while you can veg err herm cfl's not sure why you would want to as growth is etremly slow compared to hid...when switching the plants to flower those cfl's suck cause's airy buds with poor undergrowth...but since it seems the guy doesn't know much about growing i suggest he hit the grow faq an get himself a nice 250.....peace
