I bought a humidor a while back and I seasoned it and it kept around 60-65% for a few months. Since last month, it didn't go over 50% no matter what I tried. I took out all the cigars and seasoned it again. I also bought silicon and made sure all the glass panels were sealed. I bought beads and placed it in the humidor (after the silicon dried and after seasoning it).
But, the hydrometer still reads about 50%. I did salt test it and adjusted it.
I also checked for leaks using the bill method and it was fine.
I'm not sure what can be wrong. :(
