If you open the humidor daily, then the air s/b "fresh"?? A good thing in my book.
That's not necessarily a good thing . . your temp and RH s/b controlled so that you DON'T force the cigar to "absorb and desorb vast amounts of water relatively quickly". That's not good! Shows you temp and humidity control is not working as it should.
Agree 100% . . so much so that I really feel that you can't age a cigar in plastic . . period! As I've written before, why are cigars packed in cedar cigar boxes?? . . except for cigarillos! Hey, maybe some are aging cigarillos in their plastic???
Same comment here . . need to control the "extremes" and not let them occur!
