Not Chris, but yes pine bark mulch broken into roughly half inch pieces, mixed with Sandy soil and, if you have it vermiculite or peat moss.
Should look like gravelly southwest desert "dirt" with bark mixed in.

What @sueinmn said will work perfectly as long as you are not in the immunosuppressed category. Garden pine mulch is more of a bulk product and more likely to contain mold spores. My orchid guru told me that is perfect for orchids as they love this, but the doctors say not so much for hubby. He had fungal pneumonia once and 15 days on a ventilator, so I take that pretty seriously. He said it’s ok, he doesn’t remember a thing, but it is seared in my memory. Lol
