Hello John.
6500K work well for veg (Blue spectrum) . For bloom you will want to get 2700k light (Red Spectrum)
More CFL you put above them, better it will be. Use 45w & more CFL for blooming! (I Would suggest 250w or 400w in that spot if you can control the small heat it does.
Put light within 1-2inch of plants and be sure to have a fan blowing on them (Even cfl do heat)
Have a good evening!
