I have a couple of pots of these. While I can’t say what kind they are, the first thing I would advise is to remove the peat based medium they are currently in. Mine are in terra cotta pots in either rinsed pure pumice or rinsed pumice & chicken grit. As far as watering, I usually wait 7-10 days to water after a repot.

Exactly what Tyler says. They do great in pumice.

Well, I separated them into new pots in mix of potting soil/perlite/crushed granite (1/3/1). Was amazed at the size of their roots.

Should I water them now or wait a bit as suggested as they have been totally dry for some time?

I usually wait. Just to allow any roots that may have been broken during the repotting process a chance to heal.
