Haa, and so many of us want cool temps for Dracs and cool growing dendrobiums.

Well, heat is provide a heat source...what else can you do.

Humidity, misting, terrarium, humidifiers, etc.

It's always better if you find plants that work with your climate instead of against it.

Depends to a big extent on where you are in the world and where you are growing your orchids.

When I first started to grow orchids I bought the plants that provided the most desirable flowers to my eye. A big mistake. Currently I grow orchids that match my environment and the culture I provide. The orchid menu of the natural species is very large. 30 to 40 thousand. and the number of hybrids is huge and the number goes up daily. It is likely that there are some that would like where you live.

If your environment is very extreme, then you will have a costly venture to create an environment. If you can find local growers, they will be the very best source of information.
