Its good that you have a Warm CFL. Just how many do you have exactly? Another thing, I was just thinking that because you have such a confined space and the plants are growing into each other you could do a SOG experiment. Just trim all of you lower leaves cause they will recieve so little amount of light that they will actually be inhibiting the plant. Just leave your main top branches and the plant will devote most of its energy into those top branches and give you some pretty good sized top buds.
