i have a cfl homaid hood and i use up to four 26watt on top and i usually put a small lamp without the shade rotating around the middle of the plant. if ur using that setup for the whole grow, budding might take a little longer than expected but if u want a quick bud with excellent yield i would switch to either a hps or mh i would go with a 125 to 400 w just so u dont shock it from high levels of heat, of course cfl lights dont produce much heat thats why u put the lights atleast 3 inches above ur plant and i would stay within 10 inches depending on the temp. of the top of the plants. if u swith to the hps or mh i would keep the light a good 15 in. away from the main cola. and i would suggest bending the top of ur plant with the cfl to give the undergrowth more light
