Humidity
The optimal humidity for guitars is 45% at 70 degrees Fahrenheit
Incorrect humidity is a leading cause of cracking and playability problems
Too much humidity will cause swelling, leading to:
- Higher action
- Back Bow in the neck

Too little humidity will cause the shrinkage, leading to:

Always:
- Use a hydrometer to monitor humidity in your guitar

Never:
Store you guitar where extremes in heat, humidity or dryness exist
- Rooms with a fireplace
