Disa orchids are native of South Africa and despite the hot climate of their home they are actually cool growing orchids, if not alpine as they hail from high altitude areas on mountain tops and grassy mountain slopes.
Disas were described to me as like cymbidium except you could water as much as you want. They have died back and I haven't thrown them out yet.
Lesson learned - Watered into dormant period. Eventually found only a little mush in the pot. Also, probably too hot inside, but too cold outside. Not a good choice for me.
