My lithops do not look as plump as the ones I see in pictures. How do I get them to stay plump?

Question

I love in NC, where it is fairly humid and stormy in summer. My greenhouse gets humid if I leave it closed during the day. Should I bring them inside? Poker does the sucky appearance really mean anything? I don’t want to overwater.

This can mean a few different things. They do this when they need water, but they also do this when they are dying off.

Part of their natural process will be to put out replacement pups that you can't see until they emerge from under the original plant. They do this as they are dying off.

Yours don't look quite mature enough to be dying, so I would chalk it up to needing water. Give it a good soaking, then let all extra water drain out completely.
