Get a small bowl. Fill it with distilled water. Microwave water to just get it warm. Put in humidor for a couple of days. NO PEEKING! Then stick your hygrometer, digital is the best, in and wait 24 hours. Take water out, wait a day then check reading. If satisfactory, put sticks in and enjoy.
I agree with Taltos too. Weather conditions can adversely affect humi conditions inside. I live in N Illinois and I am constantly charging beads in the winter, and I rarely touch them in the summer.
If the sticks smoke to your liking, then you might not have a problem at all. My humi's have dipped down in to the mid 50s and smokes still smoke great.
