I used the salt test by putting a bottle cap w 1 tsp of salt and a few drops of water in a ziplock bag with my hygro.
The first time I got 71% but the salt looked wet. So I redid the test with less water and I got a reading of 75%.
Should I just trust the 75% and assume my hygro is well calibrated?
