even thought they are cfl's they still get pretty hot
+ you have to look at the type of plant you have it looks indica dom.
untill you learn your strain i would be growing this very carfully. keep lights 4-6 in away, dont let the plant alway touch the light before moving them , for me once they fall into 3-5in (which can happen overnight) i raise lights. this will also incourge growth, but if you have height restrictions now is a gr8 time to start LST'ing wich will give you a nice size bush keeping your plant short. incressing your yeild
