I'm so insanely new to this, but I'll say I have a lot of tupedors and different humidors and I'm a big data nerd so I track and graph all of this shit. I moved away from tupedors for everything that isn't flavored because when the temp would move around the RH moves a lot and even with bovedas the humidity would spike to high levels. My thought process is that the RH spikes and there is no where for the moisture to go in a tupedor even with a boveda it can't absorb the excess moisture unless it was already fairly far along in it's life. With a humidor the wood can take in that excess and knock the edge off. Also, and this is odd, the boveda being moved through faster it's more likely to be able to absorb some. Maybe this is my crazy theory, but it's what I've been noodling.
