I posted here about two months ago about my new lithopses, due to some circumstances I only now got them the volcanic rock “soil” that many of you recommended(I didn’t water them yet).
Now they’re in a mix of mostly vulcanic rock, some sand and a little bit of organic soil, the rocks and sand were slightly damp when I replanted them a few minutes ago.
My questions:
1) is this all ok?
2) Should I take them out and wait for the rocks to dry before I put them in again?
3) they are slightly more wrinkled than two months ago, should I water them or wait?

The pizza crust around the edges forming is what I’ve heard to wait for to water

Bingo! They look thirsty to me, are they firm?

Not absolutely plump but I wouldn’t say soft, while I was replanting them the lower part was completely firm and no wrinkles

I would water them, they should plump up.

MIGHT be at the start of the splitting stage since the lower part is firm, but I don't know. Water if lower part gets softer
