Orchids that need winter "rest"

[utah]

Working hard on the greenhouse so I haven't been on for a while. Also managed to acquire a few dozen more 'chids. Dang that EBay!

My question - some of the 'chids I've purchased (Dendrobium loddigesii for one) require winter "rest". I'm going to try to establish a "drier" corner of the greenhouse for them and the plumeria.

Is there a list, somewhere, of which types of orchids require a winter rest? I know that many dendrobiums do, (as well as lycaste, etc.) but I can't find a general (but inclusive) list anywhere.

References anyone?????

Thanks!!!
