I've actually considered that I may have too much light in that small space (what do you think?). I have tried adhere to the advice in FAQs as much as I can. My remaining plants look very healthy so far.
Others are right; you don't have much in the way of lights. You've got six square feet of floor space and about 10,000 lumens of light....about a third of what you need. You've got a grow area for about 4-6 plants, and enough light for two plants. If you're planning on ending up with either more plants or a grow area of much more than 2 sq. ft., you're going to need more lights.

With CFLs, having a light or two below the canopy really helps too. CFLs have lousy canopy penetration compared to HPS lighting.
