For peeps wanting to know how long to burp for, it depends, anywhere from 30 secs to 30 minutes, if its just a general burp I'd say 5 mins and a little shake up of the buds. If you need to dry them a bit more maybe leave 30 mins.
Though a quick tumble of the jar and a 10 second opening shall also suffice if you have time restraints, again, only if its in the 60-65% RH range!
