Guitar Humidity - Day 25

Humidity in case with 2 Dampit style humidifiers is holding at 41% RH in soundhole.  We've not experienced "normal" conditions in Pennsylvania since the beginning testing in mid Jan. Yesterday, the outside temperature reached around 60 Deg and it felt like spring. The current ambient humidity is at 31% RH.

My original plan was to monitor the decline of the humidity for a normal winter in PA. Oh well. At least we're observing what happens with large swings in humidity over short periods.

I haven't opened the case since inserting the 2nd Dampit style humidifier on Jan 13th, but I'm suspecting the sponges are dried out and moisture is being released from the instrument. As a reminder, instruments used for these studies are already humidified  to a minimum of 40% RH. I'll likely open the case soon.

The Musik Tent continues to maintain a few percent variation in humidity over entire instrument, and has consumed little distilled water at this time.
