One to Two hours of 39, 40 degrees?

It's too soon to bring everything in (still finishing my GH floor) We have about 2 hours (7 to 8 am, sun will be up)of these temps. Will this have a negative impact on my sensitive plants? (plumeria, citrus, basil and other herbs, I also have a bunch of other plants that will ultimately be kept in the GH for the winter (ferns, mandevillas etc).

Just need some reassurance that a few hours wont kill/hurt them?

Citrus and plumeria will be fine. I don't know about the others, I'm sure somebody else does. YOu know that plumeria is deciduous so it's going to lose leaves in the winter anyway.

As long as there is no frost all should be OK

RE: One to Two hours of 39, 40 degrees?

Not all of my plants have been moved into the greenhouse and the only one that suffered any damage from temps below 40 F was my Cryptostegia grandiflora. My mandevillas are still in the garden and doing well even though we've had a couple nights with frost. I'd better not push my luck and get them dug up but I wouldn't worry about your plants with those temps, especially if it's only for a short time.
