That's a really complicated question to ask without more details. So since you don't write anything about space i'm going to asume, you have the space to a decent grow.
I would divide the room into a small vegging room and a blooming room.
Vegging room needs just 18-24 hours of lights. Fluorscent will do fine. Take a warm (red) and a cold (blue) light bulb (you can get in any hardware store).
Flowering room i would say take a 400w hps lamp to get a good light that will give you decent bud.
If you are going for a smaller thing with only 1 room i would try a LED lamp.
