Just a quick check... you are using a digital hygrometer, yes? And you’ve checked calibration?

Yes and yes kind of. I'm 100% positive this hygrometer is calibrated correctly, I used it for something that needed EXTREME precision compared to cigars and it did the job perfectly. I'm being too lazy to buy salt... But that's also because I don't really have to do it because I already know. I'll do it sooner or later. as long as it's within 2% of what it's supposed to be, I'm cool with it.
