Burping means to open the jar and allow air exchange to take place. Out with the old, in with the new.
Again, I never get condensation in my jars, and I usually burp them once or twice a day. Some seem to prefer to do it more than that, but I've never had problems my way and it's easier. NO, don't take the buds out...the air can easily get all through the buds. I open mine to burp right next to the A/C unit and hold them right up to the vent. This is the driest air I can produce.
Of course don't pack the jar too tight. You can add some later from other jars after curing is totally complete, which is about a month. You can smoke anytime after it is dry, but the taste will improve as it ages.
