is it possible for mold to form when the humidity never reaches over 80%. I've had some cigars in my humidor for about a week now and this chalky white substance is on the outside of some of them and I'm concerned that it might be mold. I'm not sure really how to tell. I mean...it certainly isnt greenish...its very white, but the white powder substance isn't uniform across the whole cigar...it is a little more patchy...thats what makes me worry it might be mold. If it is bloom, how can I get it off without buying some kind of brush or something. Any advice would be much appreciated.
