    75 is the goal...... Not sure how accurate this technique is.... I rather use Boveda Calibration Kit.

    Yup, if you do the salt right, it will put off 75% rH. Accuracy has been questioned, yes. If you have boveda packs, you can calibrate with them also.

    75% is the standard for hygrometers...not hydrometers as a lot of people get this mixed up as well.
