I know Boveda claims you don't need to and I've hear of some doing so but I still burp for 14 days and use the boveda to maintain the right level for storage.
Boveda packs are the best thing ever for curing yer weed!!! I'd still never start my cure without burping my jars. But then again I don't dry until my stems snap, I jar just before just as they start to crack when you bend em but horses for courses, either way mission accomplished
