I made sauerkraut, in self defense.
HA! I actually stumbled into cabbage fermenting in a similar way. We used to dumpster dive in PHiladelphia, and one night we got like, 60 something cabbages. And yeah, what do you do with them with no cellar? So I made my first batch with some of the remaining heads (we made most of them into everything else you can think of to make with cabbages) and liked it enough to buy the book Wild Fermentation, and it's been a wonderful relationship with fermenting almost everything ever since!
Finally, I had sauerkraut from the gods. I am serious, put the grocery store stuff, even the most expensive ones to shame.
Oh I KNOW! The first time I tasted homemade sauerkraut with caraway seeds and juniper berries, it was like, something clicked in the reptilian part of my brain. My body recognized that flavor, even more than kimchee (makes sense considering my ancestory)! And I've been totally hooked on soured cabbage ever since.
I want to make those crocks with the brine keeper lids as soon as we've got a ceramic studio up and firing here....someday.....sigh. I use glass gallon jars and the normal five gallon ceramic crocks with pretty good success.
One HUGE thing I've come to realize about making brined ferments, is that the humidity of your relative climate matters - A LOT.
In Philadelphia, none of the brine from anything in my kitchen ever evaporated to the point of needing to add more.
Then I thought I'd make my mom some soured cabbage while visiting my parents in Wyoming. I just weighted a plate in the crock like I normally had done, came back a few days later and it was DRY! SO WEIRD! The brine just WENT AWAY.
And now, in California?! I struggle to keep the liquid in my crocks. I generally stretch a plastic bag over the top of the crocks, over the weighted plate and all that, and that helps. But I still have to make sure that it doesn't evaporate too much, and sometimes have to add some salty water to the mix to keep everything below brine. When our cellar is complete I think the cold storage all thru summer will help in this effort.
