It is a plant we have for years. So far it grows well in extreme heat, over 28 degrees celsius, as well in cold conditions, low humidity, high light... 
We did not try to kill it, but it would be nearly impossible. That plant is much more vigorous than most cuthbertsonii aroind. Like many curthbersonii types, they do not like too acid conditions, and we grow them like Paphiopedilim, including dolomitic limestone and standard feeding.
