You are in the right direction, eventually you'll buy or build a grow box. Trust me you will find it more conveniant for lighting and whatnot. You can make one out of a rubbermaid container, some CFLS, and a fan. This way it won't be light all the time {in the room} and chuck can't complain. The electricity used is going to be minimal from CFLs, you'll get into some issues with HPS. Just research and find out what you need to do, theres enough information here for you or anyone else to learn a thing or two. GL man!!!
