Your going to need a lot more light if you want to do any good. Those tube florescent bulbs suck. If you can get some compact florescent bulbs, they put out way more light that the tubes. And you can concentrate the light on a smaller area. You can put together some cheap fixtures for the lights. Even some fixtures you might have lying around might work. And you will do better with the larger CFL's also. As far as I know Home Depot has the biggest ones around local. Looks like your plants are stretching a lot and you have to support them so they don't fall over. That's because you do not have enough light for them. It would help also to get those lights you have a lot closer to the plants. Looks like you have pleanty of air movement though, nice size fans. Try to get the lights as close to the plants as you can. They should be able to be only a couple of inches away without being to hot.
