Can we talk about using a crock vs a dedicated fermenter for sauerkraut?

I just finished my third batch of kraut, and the difference was huge. For the first two, I used a big old ceramic crock with a water seal, the kind my grandma had. It worked, but I had to top up the water every few days and I lost a whole batch to mold once. This time, I borrowed a friend's airlock fermenter, the kind with the little bubbler lid. I used the same cabbage and salt ratio, about 2.5% by weight. The kraut was ready in 3 weeks, no mold, no scum, and the taste was way cleaner and sharper. The crock felt like guesswork, but the airlock system just felt controlled. Has anyone else switched from a crock to something with an airlock and noticed a big change in how reliable it is?

Totally get the switch. My old crock was a constant battle with kahm yeast and that weird white scum. I even tried the plate and rock method, but it was a mess. The airlock just takes all the worry out. I can leave it in a corner for a month and forget it. Do you think you'll stick with the airlock system now?

Oh the "weird white scum" is the worst. I read a blog post that basically said that stuff is a sign you're in a constant fight with oxygen, which totally lines up with what you're saying, @eva_rivera. The airlock just ends that war. Once I switched, it felt less like a science project I had to babysit. I'm definitely sticking with it, no way I'm going back to checking under plates every other day.
