That's a truly insane local climate changing amount of ad-hoc greenhouses, although it appears the bulk crop is leafy greens and organic growers market produce.

Grains are different beast again, you want millions of tonnes cheaply with efficient bulk acerage harvesting etc.

Thanks for the link, if I hadn't seen it I might not have believed it.

Those are a long shot from the level of climate control the vertical farming crowd is talking about though. On a spectrum between untouched nature and isolated artificial growing environment the Almeria installations aren't that far from the best-prepared open sky setups.
