Can you put different cigars together in on humidor?

It depends on the cigars. Some of us do, others do not. If you smoke flavored cigars like Lars Tetens and Acids, don't put them in the same humidor as your Cohibas and Punches if you don't want all your cigars to taste like Lars. I wouldn't put really powerful cigars in the same humidor as mild cigars, because the mild cigars will absorb the flavor of the strong ones. But as far as putting...oh, Partagas and Punch together...no real problem.
