I'm confused. This is an article purports to be about vertical farming, but then calls out AppHarvest -- a company building heavily automated (aquaponic?) traditional greenhouses. There are at least a half-dozen AppHarvest-esque greenhouse companies, and they almost all have positive farm economics (positive EBITDA). Same is true for many of the greenhouse-based fruit & veg outfits.
