If I were you I would just get a brooder lamp with a daylight 6500k bulb as suggested before. Compact CFL's can be your best friend because they do work for cheap. You don't even need a hood because you can hang a brooder from the ceiling. It is super easy and inexpensive. If you want a carpet, you have to have more light. I run co2, but it is not absolutely mandatory because you can use Flourish Excel, but it will wind up costing you more in the long run. I got the brooder and a 45w 5500k bulb for a total of like $27.

As well, you can add a normal desk lamp with an additional cfl if you wish. I have a glass canopy so nothing falls in. Two clip on desk lamps with t5 lighting in back
