maybe it's my hygro...i don't know...but it's driving me nuts.

i still have the hygro in the baggie. it's still sealed. when i press on it lightly, no air gets out so i assume it's sealed correctly. i took it downstairs to the basement for a moment and forgot it there. an hour later i went to get it. the temp was 60 and the humidity was 80%! ??? i brought it back upstairs. the temp was 70 and the humidity went to 77%. i have it back in the den and the temp is now 73 and humidity is 76%.

i thought the salt test was supposed to stay consistently at 75%. will temp make the humidity in the baggie fluctuate that much? if so, how do i know at what temp 75% humidity is actually achieved?????
