A Vertical Farm Replaces Sun, Soil and Seasons With Wiring and Climate Control
Strip away the renderings and a vertical plant factory is a specific piece of engineering: a fully enclosed building or warehouse where artificial lighting, wiring, plumbing, engineered substrates and climate control systems replace sun, soil and seasons. Everything a field gets for free — light, weather, soil, the turn of the seasons — becomes equipment and a setting instead. Whatever it grows, it grows on purpose, at a price the field never charged. Researchers writing in The Conversation Canada argue that these factories represent a problematic continuation of industrial agriculture's contradictory logic. That is a sharper charge than the usual one about expense: the claim is about lineage, about what kind of farming the model extends.

The design decision worth noticing is that almost nothing is left to the weather. Light, substrate, temperature and the turn of the seasons all become settings you can dial.
Dialling the weather takes power, though. A sealed building that manufactures its own climate is only as resilient as the grid behind it.
