Has anyone used a mylar space blanket to give extra heat retention in their GH? Is it as good as bubble wrap?

mylar space blanket in winter
Trouble with a mylar blanket is that the sun would not be able to penetrate. So unless you want to raise mushrooms in your greenhouse, I would opt for bubble wrap.
hmm, good point. Maybe just on the north side or down low.
