| Beware of spring, too!
I guess I'm a humidity control-freak. I have a digital hygrometer, a whole-house humidifer, and a separate evaporative humidifier for the room where the bass lives. At the onset of spring this year, the humidity was stable at 40-50% without the evaporative humidifier so I put it away. Then we hit a spell of dry weather and the humidity dropped like a rock-- I mean into the 30's!
The whole-house humidifier and the extra evaporative humidifier that worked so well all winter long were insufficient. It took the addition of a third, ultrasonic model to keep the room in the safe range.
Keep your eye on that hygrometer in the spring if you live in the northeast. |
