same here. if you create some kind of temporary frame(i.e. trellis netting streched tight) and put a plastic sheet on at night you can keep any condensation off of them.
i've walked around my property and observed where condensation forms & doesn't & it's pretty amazing how much variation wind can create. there are little windswept spots that get frost when only a little is on the roof but zero elsewhere... just because it's got no protection & steady breeze.
an alternative would be to put a big fan outside at night.
lookin good dude
