The purpose of burping is to allow the plant to cure. It takes 1.5 seconds per jar to exchange air,maybe twice a week on average, you must do it or your bud will be crap, having stewed in offgasing.. ..gases.. and stalling out the conversion of starches. Remember flushing is a myth but fresh weed is "harsh" if it's unflushed lol.
I have seen tons of chemical and organic bud ruined because people are stupid and seal the shit up permanently for some reason. All the prepackaged crap at dispos is a great example. A large portion of it would be smokable if they only burped their shit once a week instead of cranking it into little plastic cans and letting it stew for weeks.
