Question regarding Sedirea japonica care

[Paul Mc]

I just got one as a travelling companion to the member project plant. I have been doing some reading online and there seems to be some debate about appropriate care.

My understanding is that the Baker's average daytime max temps were upper 80's to lower 90's and that they could go as low as lower 50's. However, some people seemed to warn against leaving them outside if the temperatures were to exceed the lower 90's for longer than like a day or so.

Likewise, there is some debate about how low you need to keep them during the winter rest months so they don't continue to grow and tucker themselves to death. Some are saying 30's to 40's while others seem to be stating no less than the 50's.

Likewise, the debate seems to range on light from slightly more than phal (1500-2000 footcandles) all the way up to cattelleya strength! So who is right on this? What is the optimum footcandle range for growing these?

I would be very appreciative to all who add their two cents worth to this!
