Water after repotting

[guccisimo85]

I received a few catasetums earlier this week and just repotted them. I noticed the media was a bit wet (so they had clearly been watered recently). They have fairly decent new growth above ground but there are only a few very small new roots. I cut off all the old dead roots - one had slightly rotted roots - and I sprayed with dilute physan.

Now I am wondering ... is it ok to leave them bone dry in the new media? I was planning to keep them dry until the new roots are a few inches long. Does that sound like the right plan?

Thanks for your help
