same place to live?

I don't understand why you can't just make 2 small racks instead of 1 large one?

its the room in the house :tears: only enough for 1 rack, my parent dont want to see them in the house and my room is small, i have 2 dimmers

You would be using flexwatt heat tape for a rack (more than likely) so I would recommend using a better tsat than just dimmers. Flexwatt can get very hot if not controlled properly. You can also build 2 small (3 level) racks and stack them. That would allow for 2 heat sources and 2 different hot spots.
