Yeah..that’s nice. Wonder how well it works when it’s 5 degrees Fahrenheit with clouds everyday for two months.

We had worse than that and still we have a bumper crop of garlic, which we planted in September; strawberries, a perennial; and asparagus, which come up like weeds.
the trick was to cover everything with at least a foot of straw mulch... the first nice weather we had, those shoots were pushing through the top of the mulch like they couldn’t weight to get out...
our locale - just south of the cheddar curtain.
Lurking’
In a situation like that I would first think to heavily insulate the greenhouse, then pump in some “waste heat” from the residence, and use plant lights for light only, not heat.
The primary source of waste heat is likely the clothes dryer, but you would need a more constant source.
