Yesterday I bought and installed a pretty good sized safe and now I'm on the hunt for lighting and a dehumidifier. Anyone have any recommendations? Right now they would have to be battery powered as there is no outlets near the install location. Also I was wondering - I have a bunch of leftover aromatic cedar planks used to line cedar chests and closets with. Would those be ok to stick a couple inside the safe for the pleasant smell or could any residual oils cause any harm to gun hardware?
