Summering orchids in the NorthEast, when to bring them in?

[RJSquirrel]

What Bud says.. I left the phals/vandas out to about 50 and the catts/paphs down to 40.. I wont have to bring them in again this year. Its still 95 in the day and now I have to think about heat too

It got down to 40 F last night here. My Dens are still outside but next to the house so they have a little protection. Keeping a close eye the night temps from here on......

first one is: Ctna, Starrlyn 'Yellow Flare'. It seems to bloom on every new lead.

second one is:

third one is:
Lc. Ann Akagi 'Hihimanu' (Puppy Love x C. walkeriana') It also seems to bloom on every new lead. It bloomed shortly before I placed it outside.

fourth one is: C. New Dawning 'Flowers Galore'. it hasn't bloomed for me yet. It has four sheaths. I see something developing in some of them. It was a sale orchid from Hausermann's orchids.
I reviewed the order here: http://www.orchidboard.com/community...ann-order.html

The leaves looked wonky when I got it. I am not sure if it is sunburn or what it is on the leaves
