I would make the rows fairly short and just stretch the plastic over the
hoops and put a rock on each end. In the morning, take the rock off and
fold the plastic back so that both ends are open and the air can
circulate through the cover to keep the temperature reasonable. If
closed up, on a sunny day it can get above 130F in there.

The clear plastic won't help all that much on frost control. You might
need to cover the hoops with a tarp if you are expecting a clear cold
night.
