How low can we go?

[Pinkcat]

I do have a heater, but my insulation leaves something to be desired...
I would love to see that article. I know that my poor little plants would do much better in a warmer/more suitable environment, but I am always surprised at how much abuse plants can take.
I am going to evaluate any damage, bring in the last vanda, and a few babies and go from there. At least I don't have to worry too much about freezes where we are. (fingers crossed)
