Any spanish cedar in there? Trays, etc.? Brand new sticks straight from a shipment (usually higher Rh)?
Never had any issues with my tupperdor's with spanish cedar trays and 2 60 gram 65% boveda's in them. Just wondering if something you added (trays, sticks, etc.) are at a higher Rh, causing it to spike.
