No change from yesterday. I do note that after I check and record the humidity, and increase the thermometer setting from 68 deg F to 72 deg F, the ambient and Musik Tent humidity drops by about 3% RH for awhile. Makes sense that warmer air has more capacity for moisture, making the "relative" humidity lower. I'll note how long it takes for the RH to rebound.
UPDATE: A customer asked if it's okay to place electric guitars inside Musik Tent. Yes, the climate inside a Musik Tent is not really that humid - compared to outside. Currently, in Center Valley, PA the outdoor relative humidity is 84%, while my indoor home humidity is around 24% RH with the heat running. Inside the Musik Tent, my guitars are at between 45 and 50% RH, which is ideal for wood and electronics. Otherwise, you'll likely develop cracking of wood along the grain boundaries. Also, if you notice the fret wires are extending out on the neck, this is likely from the neck shrinkage (a.k.a. Fret Sprout) due to dryness. So, it's advised to keep ALL guitar necks oiled properly and/or under humidity control. See photos and read zzounds article at https://blog.zzounds.com/2017/06/29/the-story-behind-fret-sprout/.
