I have multiple coolerdors all with well over a lb of Heartfelt beads and recently I put 2 wireless hygrometers in one of the coolerdors. Much to my surprise I got 2 significantly different readings. 66% and 75%. I thought "wow they are way off" Put them next to each other and voila! within 1 point each. Move them around a few times with essentially the same results.
Can the RH vary that much in the same container??
Am I missing something?
If it can how do you equalize it?
