Beginner Questions (Ask Them Here!)

Been smoking for years, but never had a humidor. I am getting one next week, used, read about seasoning, humi beads and the like.

My question is about the humidor, it is 8 x 9 x 16, it has shelves in it, can I stack different types of cigars on top of each other, or should the same cigars stay on top of each other? If I have to seperate them what could one use to keep them apart?

thanks
