Dendrobium Kingianum in S/H?

[greenpassion]

I just purchased a totally new orchid-A Dendrobium Kingianum, and in reading about it's cultural needs, I am at a loss. The seller has reassured me that it would do well in S/H, and in fact, he knows someone who actually has one growing in water. The problem here is that in reading up on this plant, 2 things came to light. One, it has to grow COLD, not cool, at night, around 5o degrees in order to flower, and two, is that it has to stay very dry. In S/H culture, this doesn't happen.
I have never grown ANY dendrobiums, only phals and oncidiums. Any feed back would be apprieciated.
