raw 225 has got it, i would add something to put the lights on/ to hang from, container for soil and electricity to power everything... plenty of folks have used closets in the past, cfl or not... however i would also add that an outlet doubler (plugs into your light so that two lights can be plugged into one socket, 2.50$ from home depot) is a simple and easy way to double your lumens while limiting your power usage...
