Maybe others with more experience will chime in... I have a small (freebie) humidor that is not seasoned and doesn't have any humi devices that I keep on my desk. I try to run my DPG humi at 63 or so, so most are good to go at that level. If I have a larger RG one, or one that is fresh off the truck, I'll generally put it in there a day or two before I think I want to smoke it. By then I usually have changed my mind and put it back from whence it came.
