Low temps for Paph species

[Jeff214]

Looks like the lows my area will dip into the mid 40s + rain (for the first time since... spring). Based on info on slipperorchids.info, the species that are:

Warm growing that need to be brought in: philippinense, sanderianum, and Michael Koopowitz (philippinense x rothchildianum). Also Paph. Hsinying Alien, which is 50% sukhakulii, 25% lawrenceanum, both warm growers?

Cool growing and might be able to take upper 40s: parishii...? I asked Fred Clarke, who lives in a similar area and he mentioned it was fine to grow this one outdoors all year.

I also have a Phrag Olaf Glauss (besseae x pearcei), which is cool and warm growing, respectively. I should bring that one in just in case...

I wonder if that sounds right?
thanks!
