-60 where ya at?
Maybe get a heater, but that sounds like it might get expensive
Whatcha growing? Or killing?

Where are you, McMurdo Station?
If the interior temperature gets hot enough to activate the openers then it can’t be that cold outside. Those windows aren’t going to provide THAT much insulation.

Mine open when the sun is on them even if it’s cold af outside, but it doesn’t get -60 here. I doubt the sun would be enough to warm them in that kind of cold.
I ended up just unscrewing the little thingies that determine how wide it can open, rather than remove them altogether. Much easier.

I am leaving them always on. At times with 0 outside gh could get to 35c if sunny ( talking Celsius )

With 8 mm twin wall polycarbonate as your insulation, you will need a lot of active heating to keep it above freezing at any temperatures below. 0°f
Your spring vents won’t open unless it’s well above freezing so you don’t really have to worry about those
But again with those temperatures and the type of greenhouse you have, you’ll need either robust heating or you’ll want to leave it empty or only grow winter crops that are cold hardy

Is that the greenhouse from Costco?

If it gets that cold you should remove it and reinstall in the spring. The wax in the cylinder will become damaged if it is frozen that long.

The instructions on mine say not to let it freeze! So there’s your answer. I did accidentally leave it for a few months where it was exposed to slightly freezing temperatures and it survived but don’t risk it.

You need a moving van and gas money to get you to a place that doesn’t get that cold.
