First, your light is too small, you need ideally 600w for that space, 400w will do. Lighting is everything when it comes to growing.
Second, if you start from seed you start with 15 to 20 plants not 4. To get the biggest yeild you need to do an Sea of Green (SOG) style grow you can look that up doing a search in this websight along with many other questions you may have.
Third, what strain you want to grow depends on what kind of smoke, buzz, and yeild you're looking for.
Forth, you need to look into ventalation and odor control before you start also.

LOL and Happy Growing.
