Dude you obviously haven't done any research of your own at all.
That is a main question which requires you to do some reading and learning. It doesn't really take that much.
You need to decide how and where you wanna grow. How much are you gonna grow? How many plants? Where do you live? Apartment? House?
Do you have nosy neighbors? What's your budget?
Fluorescent light penetration is not the best, but it has its advantages, especially if you grow indoor of if you don't plan on growing more than 2-3 plants. I grew bigger plants with like 4 CFL lights than some people grew with 1000W HP lights and MH conversion bulbs combined. Just check out the pics
