Fermenting the vegetables in 2,5L glases I always face the problem that the vegetables soak up a lot of water and then dispense a lot and then towards the end soak up even more. The problem is, that the airlocks get soaked out when the volume in the glass diminishes. They are just too short. I use the standard one.
I consider airlock as important. What I did so far is to wait 2-3 days until I fill in the water in the airlocks, but it didn't help a lot. Often the airlock breaks and it soaks in the water from it.
I wonder, whether there is a point in time, when it can't happen anymore, or anything else to know about the stages of fermentation?
