Read the grow Faq on this website all the way thru and then re read each section as you grow. Also download some ebooks on the subject and read them. It is all basically the same info just a little different.
Then decide on if you are going hydro or soil.
Get some flourescents to veg with and an HPS to flower with and you shouldn't have too many problems. The first grow plan on making mistakes, it's unavoidable. By the 3rd grow you should have everything down pretty good.
