With winter coming up, I was thinking about my humidor. I don't keep the heat on too much because, frankly, I don't really like it, it is expensive, my house stays warm enough, and I kind of like the cold. But my house can still get pretty chilly. Everything I read, though, says that cigars should be kept at 70°F/70% RH, or 65/65, etc. What I was wondering was does anyone know if there is an absolute humidity that cigars should be kept at? I find it hard to believe that the relative humidity is a driving factor (but please correct me if I am wrong).
