I have a few 2-qt jars that I mainly use for storage. But I've cured using them with no issues. I was kind of forced to use them to cure because I couldn't find any wide mouth Qt jars at the time I needed them, so I bought the 2-qt jars. Perhaps not as convenient as the Qt jars for me, so I will mainly use them for storage and if necessary, to cure. I have stopped using the Boveda packs. I like to use an H2O spritz on the underneath side of the jar's lid, if I need to raise or maintain the RH in the jar.
