Donna,
Yes, I know what you mean, about needing a space between thje plant and the cover. One year in Oregon, I did get up early and watered the frost off the plants before the sun hit them. You know, it did help!
I hope that you can get more sleep. My wife Lin is that way; she is often up at 4:00. I am up sevral times but usually I can go back to sleep.
