Creating Papua New Guinea mountain rainforest

[poiuytre]

Hello all. I have a few very small orchids native to the cool highland jungles of Papua New Guinea. I don't know what species they are, they were given to me by a friend of a friend who works at a tropical flower conservatory.
I've tied them to a plank covered in sphagnum moss with a wire hook on top to hang. I am unsure how to recreate its native habitat of high humidity and cool temperatures ranging from 50-75 degrees. I have a big west facing window that I put my other orchids in front of but I don't want to place these ones there because they may get too hot. I live in San Francisco where the weather never gets too hot or too cold. Any help is greatly appreciated. Thanks.

I would be inclined to think they might actually do OK outdoors where you are. I have a few species that come from similiar climates and grow them outdoors and only bring them in when the weather is very cold in winter. Have you got a reasonable level of humidity there as I have found that with a bit of compensation in the watering regime and some careful positioning to allow for shade, etc things adapt surprisingly well.
