All of you who wanted to be able to account for trays... I'm sorry, I can't, I just... can't. I just spent the past 3 hours stacking cigars in different humidors with and without trays and there is no pattern, no formula. It all depends on where the trays are mounted in the humidor. Some are mounted 3" deep in the humidor, and with certain ring gage cigars, you can get three rows of cigars beneath the tray, others are mounted 2.75" deep in the humidor and then most ring gages can only get 2 rows beneath them. So a tray could displace 10 cigars, or, if it is mounted a half an inch lower, it could displace 25 cigars.

I failed!
