I was just asking a question boss, and sharing what I read. I honestly don't think once a week would be enough to keep fresh air/oxygen in a jar though. I'm no scientist or nothing, but I'm sure with the processes going on that oxygen gets used up pretty quickly, hence having to burp your jars more frequently in the beginning. Just my opinion. He does go on to storage after curing lol I'll be back later on. Like I said I'm not saying this stuff is absolute fact, right, wrong, or in between. Just relaying what I read. No hard feelings. I think boveda is 2 way moisture control though. I'll have to check the packs.
