How much space are you looking to use in your closet? All of it or some of it? Also how much money are you thinking of spending? To start, I would say start browsing the Grow FAQ, there is a lot of helpful information in there for new growers. Also, go to google and search closet grows. It will pull up web links to all kinds of websites and that way you can see what different growers are doing with their closets. Sorry I haven't been much help yet, there is still more info to figure out. UP your posts though so I can actually pm you
