I will give you a couple of suggestions to help seal your humidor. First, if it seals by having the inner Spanish Cedar lining rise up about 1" to mate with the top, wipe down the top and the risers with distilled water-it will make them swell up a bit and seal better. The other suggestion is to get your hands on some sail wax or bees wax and rub that on any spots where the top and bottom make contact. This will also help to seal the humidor. The other normal advise is to obtain beads and use 1 and 1/2 as many as calculated and invest in and properly calibrate a digital hygrometer. Take these steps and then decide whether your humidor has croaked. For the record, spring, summer and fall I need to add water monthly, but winter in New England with the total absense of humidity, I am adding water every four days and my humidors do seal properly. Good luck my friend.
