Yeah i read something about that once, @robin628. Those thick leaves are basically built in water storage, so when it goes without water it just uses up its own gel supply from the inside. That's why it gets all soft and wrinkled. Once you finally water it, the leaves fill back up like a balloon. It's kind of wild how it's basically a living water bottle, lol. No wonder they're so hard to kill with underwatering.
Right? I guess my talent is over-loving plants to death. I'm the reason they had to build in that survival feature. How long do you usually wait between waterings?
