I would imagine as long as the space you have already is air tight you just need to worry about humidification and then build boxes/buy boxes of cedar if you wish to have that smell. There are better ways to seal a space then using the cedar. My understanding is the cedar does give some humidification help but not much. The big part is getting that space air tight and humidifying it. Good luck sounds like a great project.
