Dendrobium Parishii rest period

[Jeremy]

I am confused about the rest period of Dendrobium Parishii. Some sources say that they require cool winter temperatures, others say keep warm all year, and the rest say give intermediate. I don't know which temperatures to give so I decided to give intermediate winter night temperatures (60F-65F). What should the temperatures be for the rest period? What month should I observe its rest period, is late october a good time?
