Yesterday i found out that my problem with getting the humidity down to 70, instead of the 74% showing on my digital hygrometer, might not be a cabinet problem but may be a hygrometer problem. This weekend i've bought a Xikar hygrometer and that one now says the humidity is 64%. (almost like the analoge hygrometer that comes with the cabinet) After seeing that number i immediately put in the humidifiers back in there. I hope the Xikar meter is right and that my problems finally are over.
