Hey guys... got my Humidor back in February, so I'm fairly certain that the cedar has seasoned properly by now. My question is, how often should I refill the humidifier? It seems to stabilize around 65-66% and will sit there rock solid for a week or two and then will lose about 1 point a day until it gets down to around 54-55%. I think the 65-66% range is ideal and doesn't really go much higher as the humidor is over half-full But i don't want to take the chance of catching mold by refilling as soon as it drops to 64%. I guess in a nutshell, how low is too low?
