Are they completely out? or "out" as in no lid?
I usually grow mine with no lid - or sometimes with lid but lower humidity than the prop domes. I'd be interested if you've kept them happy enough completely out in the open.

love tubers.

I'm not sure what you mean by completely out. They are in a little solo cup with no lid or covering. They are just out like my african violets. I won't say I've kept them completely happy, but I didn't keep any of my plants completely happy over the summer. They are okay, though.
