Brian, My info on this is not recent, and there may have been advances of

Incidentally, I'm a believer in rock walls, but that is easy for me because
I live on a terraced property with a total of around 300' of 8+' 80-year-old
retainer walls, with a base greenhouse built between one of these walls and
the house, which has 1'-thick brick walls. I've found that a variety of
rock-wall/greenhouse configurations works well to provide a variety of light
and warmth requirements. It has been important to balance the need for
sunlight as the primary heat source and the benefit of warmth retaining rock
walls. Besides the base greenhouse, others, extant and planned, have one
tall rock wall, lower or graded side rock walls and a wall (opposite the
higher rock wall) either has only a low, rock base or a relatively low rock
wall -- to the height of the benches.
I'm experimenting with heat lamps aimed at the rock walls this winter.

Have been thinking about the rock walls. Though I plan to continue with the
rock I have been using. Went to a Home and landscape show yesterday. Saw
this guy who sprays insulation foam for houses. If one was to get a guy to
spray a wall with a ft thick of this stuff, then cut it the way they want
and cover with a thin slab of concrete. They could have a rock wall in a
few days. Would be something to see how well it works?
