Your set-up sounds more than adequate, much better than my own. The
local display greenhouses grow CP's in the cool orchid house.
(Personally I think they deserve their own room). The only problems you
may run into are salt build-up from the tap-water used, and inadequate
lighting for the Dionaea. It's hard to keep them satisfied with
artificially lighting. Also the lava rocks may cause problems for you,
but I'm not sure as I've never tried lava rocks before.
