not to jump in with the obvious, but the more cigars you have in your coolordor, the easier it is to keep the humidity at the proper level. or even better, fill your coolordor with boxes of cigars. when I first got my coolordor going, it ran very high in the humidity department (I even, gasp, had some mold appear on some of my cigars). so, I began getting as many cigars and boxes of cigars as possible. now everything is going well, and I have an excuse to give my wife everytime I get new cigars. "Honey, I have to get this box of cigars or my other ones will be ruined"
