opening/closing humidor

Think about buying cigars at the local B&M. They're removed from what's typically an over humidified environment, placed in a plastic bag for what could be days, and they still smoke well. Temporary changes in RH isn't going to destroy your cigars. Think about what you're trying to accomplish with a humidor. You're attempting to create a small little temperature/humidity controlled world...for about $100 depending on what you've budgeted. It's never going to be perfect all of the time. I'm having the same issue with my 100 count desk tops as far as maintaining RH in a room with ambient humidity in the 30% range. I'm just finding that I need to keep a closer watch, and check the humidity every couple of days instead of once a week or so. Each time...I'm having to recharge the foam puck. I saturate that, and have 2oz of 65% beads in with it (sometimes I recharge, sometimes I don't), to stabilize and maintain the RH I want.
