It's neat stuff, Bower, but I don't see any pics of greenhouse benches being covered with it. It looks like the product of choice for almost any other use, though. The earth is constantly giving off small amounts of heat, at least when unfrozen, and that is the difference between the ground and a bench of containers.

I don't think a fabric that can 'breathe,' so to speak, can have an r-value, or much of one, but yet that breathing trait makes it superior to poly as a plant cover outside or in a high/low tunnel. The earth gives off humidity, too, as do plants, and that moisture needs to go somewhere.
