What should the humidity level be in a humidor?

A humidor is a box for storing cigars or tobacco products; 72 percent relative humidity is ideal, but between 68 and 78 is acceptable.

70, 70 is ideal. 70 degrees and 70 percent humidity. 72 percent humidity would be considered a MAX for storage only. Many brands will not smoke at 72%. 68 to 69 % is preferred.
