Tony, I think the temp they need leaves us out. Humidity too. I can't ever remember a 70 degree nighttime temp. They would have to live with temps below 70 a lot.

ENVIRONMENTAL CONDITIONS: Best suited to moderately warm humid climates, 70°-85° F. (20°-30° C.) at 70%Rh. Ideal in protected cropping. Not appropriate in hot, dry environments.
