perfect the bulbs you are looking at works good my closet was the same size. i used 3 125 w fluo. for 3 plants. and when it come for the 12/12 flowering part you can get 2 125w 2700k compact fluorescent lights. these lights will take care of your heat problems. but for the smell your plants are going to be kicking out , i would go with a oil scented plug in 2-3. keep an eye out for the maintaince man cause they come in to change the batteries in your smoke detectors.
