I used jars for many years. Usualy worked great, but I have had a couple of infected jars.
Last year I tried Grove Bags for the first time and I won't turn back. No burping, a good cure, and long term storage. As cheap as a moisture pack but doesn't dry out or bloat like Boveda can.
Thee are lots of opinions but to me the humidity packs affect the smell and flavor, long term. So far my Grove stashes have stayed fresh and terpy.
Sometimes they will send a sample, but the 1oz bags are only a couple bucks. Why not use your usual jars, try a grove bag, and compare for yourself?
I should mention that I still use a big 67gr 58% boveda to stabilize the environment inside the larger box that contains the bags.
