I've been searching the net for a perfect answer for you but I'm unable to find one I'm satisfied with. Here's an explanation that I found helped.

"Oxygen is feeding the microbes that live in the air naturally. They go to work on the chlorophyll, sugars, starches and whatever else they find to eat. The issue is they seem to be facultative microbes which means they prefer oxygen but can start to process food anaerobically fermenting the cannabis in the process giving you that funky ammonia smell. Once the jars stabilize at a low enough humidity there is not enough moisture for the microbes to persist or once the food supply is used up cure complete."
What I found dude on net, it sits right with me, point being, if buds goes in jars at the right humidity level there’s no need to burp every day or every day etc regardless if it’s in first month.

At this point, proper moisture content is closely monitored. If a container is opened and the buds are excessively moist, the container is left open until desired moisture content is achieved, or the contents can be placed on the drying rack and closely monitored.
This process is repeated over and over and over again until the perfect, uniform, desired humidity and moisture content are achieved, therefore, opening jars is counter productive if the buds are at the right moisture level. And therein lies the art.
