recently bought a used table top style glass top 100 stick humidor off an acquaintance. it had been seasoned and is perfect condition. i tested the hygrometer with the salt test, read as perfect. it came with a couple triangle shaped bars full of water activated gel beads as well as the standard green foam 'block' that mounts inside the case....

my issue, as stated in the title, is that no matter what i do, i can not get the humidity to rise above 50. i tried a gel bead bar, 50. got some 'cigar juice' solution, soaked the foam bar, 50. set a bowl of distilled water inside. 50. put it in a very warm, dark closet, 50. set it on a table away from windows, 50. originally i only had about 10 sticks in it, added another 30, still reads 50. nothing i seem to do raises or lowers it any. only thing i have not tried is using both bars and the block, but that seems excessive.

any suggestions on things i could try or possible causes?

thank you, appreciate the advice.
