you only have 1 meter of room? the electricity you pull has nothing to do with the size of your space. how much physical space do you have? how much money do you want to invest? how much electricity do you want to use? is your room private?

definately do something about the smell. it's a minimal investment for your setup. don't skimp on the things that can help you NOT get busted! the box would have to be air tight to contain the smell. even then your gonna have to open it.
