i think most people will give you some crap about not respecting your roommate. that being said, i can understand your zeal. keep in mind that the plants need both ends of the light spectrum throughout thier life. they need some red during vegging and some blue during flowering. so i would suggest 5 to 1 blue during vegging and 4 to 2 red during flowering, assuming wattages are equal. let me say also that i'm no expert, most of what i say i got from the lips of others (well, not thier lips exactly, the typed word, but same diff)

anyway, i'm using cfl's myself, come on by and check it out
