I just tried the salt test for the first time, having previously used Boveda packs. Prior to the salt test, my hygros were reading around 65% (the normal RH for the beads I use). After the salt calibration, my 3 hygros all read 71%-72% in my cooler. I think it's the salt calibration, not higher relative humidity. And I was hoping I had found an almost free way to calibrate.
