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?
