Yeah, I've gotten them to grow leaves pretty well. I've been leaving the floating leaves until they completely rot. I think I'll try removing them earlier as they are preventing the new leaves from going aerial.
I've also gotten very good at forcing the plants to tuber up. I have 5 varieties and I've done it to 3 so far. Good thing is I know why it's happening how to do it, so I can divide my plants earlier if need be
