Yes, I have a digital hydrometer. I does usually stay at around 70-75 with or without the humidifier. I'll go for a bit without the humidifier in it. Do I need to worry about the small amount of mold that got on the wood under the old humidifier? Like I said, I wiped it off with a paper towel (dampened with distilled water), and dried the area...is that good enough?

Thanks!
