Since no one is rushing in to answer your question... Louisiana may be a bit warm even for this species, but since C. kentuckiense lives naturally there you may have a shot.
I've tried them in pots here in southern Japan, another warm climate, with mixed results. I think a large pot is a good idea, situated in a completely sunless location. That will keep it cool. I'd use a big clay azalea type pot to aid in evaporation. As for the compost - something very airy like large perlite, chunks of coir, etc, but also perfectly draining. You can use fine bark as well, though you'll have to repot frequently.
Of course you'll need to feed it quite a bit with that kind of compost. Don't be shy, these guys can take more fertilizer than most Cyps.
Honestly I've done much better with this species in the ground here. The ones in pots always just sat there after a while. The truth is it is tough to grow Cyps in warm climates, but if you're going to try one, this species is a very good choice. Good luck!
