Your microclimate will also be a factor in this. I would just go for it and see what happens. May work some years, not work for others.
One trick I’ve seen is to take black barrels and fill them with water. They will act as a heat sync during the day inside your greenhouse and give off heat at night when it’s cooler.
I'll look into it. Thanks!
