Can I recommend getting some auto air release tops?  If you don't burp those jars regularly you're gonna get completely covered in kimchi juice when you open them.!!! Good luck though. looks delicious! 

 I do have some (see below). I don’t tighten the lid all the way, just enough for it to “catch” on the jar threads. For longer ferments I always use the fancy air tops. https://image.nostr.build/7cfb3be28a4ef0b67c37c5bbfa0bafb03f426f08f6eeb9f5ec817b33e4b1106d.jpg  

 Fantastic.  Since it was your first time makign this I just assumed it was your first time fermenting and felt obligated to help you avoid a gaszastersplosion.  I bet it's going to be delicious! 

 It’s pretty solid. Slow creep on the heat. Next batch I’m going to order proper chili flakes and not use gochujang.
