congratulations, you just asked the most popular question on the site with your first post. you should get an award or something.
ok, here's the deal - we have all tried at one time or another to get an easy answer to how much yield for what kind of set up. if we all knew the answer to that, we wouldn't be on the forum very much.
after those warnings - IF YOU DO EVERYTHING RIGHT - then a noobie can get anywhere from a half ounce per plant to 6 ounces per plant. i realize the range is rather useless but that's the best anyone can really give you.
