People here will help but they won't do your homework for you. As Irydyum said, buy the book. Failing that, start reading the tutorials you find here. You will find most of the information that you are asking others to research for you. Seriously, not to be rude but I don't have the time to be your one on one tutor.

Start by reading this tutorial. Read the whole thing. Take notes.

Also see the tutorial in my signature line below on grow room setup.
