I've had a 100 ct. humi for @4 months. over that time it's held a pretty good rh and smokes have been great. over the last week my cigars have started cracking and unravelling when smoked. I haven't changed anything in my setup, so I'm confused as to whats going on. I topped off my humidifier today. It hadn't been touched for about 2 weeks. RH was still reading 68%. I also added a second hygrometer to verify my main one was working.
