>> If I can find a wealthy codger to fund me, I'll build a refrigerated greenhouse! hahahahahaha!
That went through my mind, but I bit my tongue and shrank it down to "a few cutting in a cold room".
But they would be very big when you put them outside.
Mostly I hear about people "pushing their Zone" by wrapping plastic and blankets around heavily-mulched things to get them through a cold winter. That's easier than air-conditioning a greenhouse!
