I would maybe consider flowering a little earlier next time as smaller plants dont need as much light, they will mature to their full potential, where larger plants may not due to lack of light. Or if you really want to "grow big or go home" then get some 42 watts on the tops, or better yet one of those 100+ watts CFL's, those will cast powerfull light about 2 or 3 times further. With 23 watt CFL's the plant effectively needs to be with an inch or 2. Those 42 watts work pretty good up to about 4 or 5 inches, and the big 130 watt around 7 - 10 inches. I highly recomend the 130 watt, it can be cooled easily and plugs right into the wall. I think your a good CFL grower as it looks like you make good use of your space. Looks good.
