its plenty of light for now if they are just in veg, and it may even be enough light for you to get a decent amount of buds, but its not gonna get you killer buds... if i were you, when you go to flower them, i would go and get as many of the biggest watt cfls that you can find and afford in the 2700k area and place them all around your plants to add some extra lumens .. do you know the k rating of the bulbs you have now? or do they say bloom or veg on them ?? the only down side i see really is lack of strong light for flowering, although i have seen plenty of nice cfl grows on this site, so it can surely be done..
