Super soil ingredients in Chicago

Hey guys getting ready to start a grow here in the Chicago area i'm looking for somewhere to get everything for the super soil mix I checked out brew and grow today and they just don't have everything I need does anyone have any recommendations for this area? I come from Denver and there are a ton of great grow stores but Chicago seems to be lacking Thanks

Thats cuz chicago sucks black balls and so does Brew and Hack try igrowhydro.com or HTG your not gonna find any local guys that wont rape you.
