That setup will be fine for vegetative growth, but you will not harvest many buds with fluorecents (of any Wattage!) Those plants look like indicas to me, so you will not have to worry about height restrictions.
If you get serious and go buy HPS, upgrade from paper to kitchen foil to eliminate a fire hazard. This shit right here is the essence of homegrowing, and I wish you the best of luck mate.
