Boveda hygro calibration being weird?
I just picked up a Boveda hygrometer calibration pack to finally calibrate my hygrometer (digital, Springfield, one of those Walmart ones). It's got a small ziplock with a 75.5% humidification packet inside. It's a little big so that in order to fit it into the ziplock it has to overlap a bit with the humidification packet and the bag scrunches up. Doing this, the hygro reads a consistent 70%, right away and stays for over a day.
Then I took the hygro and the humidifier out of the Boveda ziplock and put them in a larger ziplock from my house, next to each other but not touching. Right away, the hygro went up to 74%, but then after a few minutes started to climb down all the way to 65%, and stayed around there for the day.
So I have no idea how to read this. My hygro is giving me some pretty wacky readings from this calibration pack. It reads 70% in the included ziplock but that's too small so I think that might not be accurate. My theory is that it's accurate within about 1% (that's why it said 74% in the larger ziplock) but the small humidification packet is too weak to humidify the larger ziplock, so that's why the reading started to go down. Any thoughts?
