Dennis asked re potting Wilcoxia and Peniocereus
When you say big pots, do you mean deep, or do you mean shallow-but-wide ?
Use plastic pots. They will tell you when it's time to repot. Big means all
dimensions with these.

I doubt Wilcoxia could have survived the heat of the low desert near
the Salton Sea where we lived before. I found by experience that very
few cacti can survive 120F+ high temps!
No problem as long as they're shaded and the pots don't get sun to heat the
soil. This goes for most (but not all) cacti - they're fine with 120 F /
50C if they have some shade and the roots don't cook in a sunny pot. If
nights cool down a lot these CAM plants are even better.
