I know it’s important. I live in northwest Ohio and are summers are usually wet enough. The winters tend to be dry though. We don’t heat or air condition too often. We usually keep the heat at 60 in the winter time and don’t have central air so my music room swings a bit from day to night. Should I be doing anything to control humidity?

Dryness in the winter could be a problem. Buy a humidity gauge and try to keep the guitars in 40 to 60% range.

I don't think short term changes are a big deal such as day vs night as long as they aren't extreme. In my non-scientific opinion, humidity changes over a period of a week or more are the ones to smooth out. In the winter you probably should be humidifying even if the house temp is only 60. In the summer the humidity is probably ok on average in Ohio.

The Royal College of Music in London has a museum of instruments which are all hundreds of years old. Violins, cellos, guitars, harpsichords, etc. They keep the room at 30% humidity according to the strip chart hygrometer. The temperature felt to be around 68F. I bet your home is below 30% humidity much of the winter, so you should probably monitor your guitar room and bring it up to at least 30%.

The non-technical evaluation would be if your guitars need setup changes every season. That would be a diagnostic that the wood is changing dimensions and thus stressing the structure.

Our un-scientific hygrometer hovers around 80% but sometimes jumps to "high" but sometimes gets down to 60-70% when we run the A/C. The joy of living in Taiwan. 85 degrees F with 85% humidity is not fun.
