I took a look at some of the posts on mold/plume and took as close alook as possible at the picture in the first post of the thread. A few observations which leads me to think that this so called“problem” is plume and not mold: first, the cigars wereleft In the same humidor and the white spots disappeared—typical of plume and quite rare for mold as plume is a crystal which often falls off; no report of discoloration where the white spots were -again typical of plume and rare in mold; and the white spots do not look fuzzy like mold—looks more like plume although his one picture is hardly definitive.
