You might be right about that. It was the only Boveda I had just lying around. I'll have to keep an eye on it and see how it behaves. A Boveda in a totally sealed environment will surprise you. I'd actually like it at 65% though just because I think there'd be less chance of mold the drier I keep them. I don't have much control over temperature and in the summer my stuff gets pretty warm. I can freeze for beetles but I'm a sitting duck for mold if it gets too moist in there. I may pick up a couple of 65's and bag up that 69% for a backup again.
