if you are able to grow and flower the cats and Dendrob the the Encyclias should not be a problem.

This is a discussion on Cool growing..... within the New Growers: Ask the Senior Members forums, part of the New Growers category; Hi all, Using up some spare time before I go back to work looking through ...
Using up some spare time before I go back to work looking through the Growing Orchids book I have by Rittershausen....and while this is probably a bad idea (space and $ issues!) I am making a list of orchids I want to try.
In doing this....I keep coming across "cool growing". I'm interested in the Encyclias, for instance, and it calls them cool growing. What exactly does this mean? In order to bloom/grow reliably, do they have to cool down each night to a certain temp, or a winter cool down period?
I'm looking for basic, fairly easy/intermediate things to grow on window cills to add to my list. For the most part (aside from some low humidity issues) my phals, oncids, few catts, paphs, phrag, and dendrobiums are fairly happy here with new growth and some blooms.
It depends on what you consider "cool growing", to me, Encyclia and its ilk and Phals are warm (but not hot) growers. I have an Encyclia right now that is currently out of bloom an did fine in my apartment when it was around 60-75° F...to be, the cool growers are more along the lines of the Pleurothallid alliance who like to be considerably cooler than that...they are fine when they are around 70°, but prefer to be cooler (65°-55°) and from what I have gathered, Draculas like it cooler.
Murray, thanks for the info and for reminding me of the online encyc. ATester, thanks for sharing your experience w/the encyclia growing ok with phals.
