I can see seven cola bud sites on the plant, looks great! I just also can see her if you'd of been flowering with a 400 watt hps and it would be HUGE, depending on your nutes of course!
Even the 150 should help, but yea like the other user said, still use the cfls too, drop them in close to the side for more light since they are cool, unlike the hps. my 400 hps ran me about 14$ a month, incredible!!!
