the flouros will not put out enough llight to develop anything more than skimpy flowers
if you only have a few bucks go buy a 4 pack of spiral compact flouros(100watt or more) as these will have enough light combined with your 2ft lights. For veggin keep a 18/6 and flowering go to a 12/12 light cycle. Check out overgrow.com under grofaq on top. By the way you DO need alot of light to get really nice compact buds!
