So I bought the little round hygrometer - did the salt test, off by 5%, took it to the B&M, they put it in their humi, said it was off by 1%...

So just for fun, I did the salt test last night - at around... 1AM. Looked at it this afternoon at 4PM - said 73% - all happy, left it in, closed the light. After a couple hours, it read 68%... and now it reads 72%... what gives?

And yes... I'm gonna order 70% beads now... finally given in...
