Just a heads up, but if it was a spanish cedar smell it had, thats not a bad thing and is completely normal for humidors to have. If it was me personally, I would not have done the coffee/vanilla mix thing. I'd be too afraid that it would be imparting unwanted aromas into my cigars.

Looking good though. Not sure what you meant by "box racks" but if you mean something like the top tray for storing singles and not boxes, you could also use these trays if they fit. http://www.cheaphumidors.com/other/c...h-divider.html Or you can just get some empty cigar boxes and fill those up to use as single storage.

If you end up deciding to build more racks or whatnot, be sure to use spanish cedar for it.
