I grew up on a 40-acre corn farm in Iowa, and the idea of vertical farming always struck me as a sci-fi fantasy. But after visiting a commercial vertical farm in Chicago that produces leafy greens with 95% less water, I'm seriously questioning whether this technology can actually replace traditional agriculture. My uncle's farm struggled through the 2023 drought, losing nearly a third of his yield, while these indoor systems ran without interruption. The energy costs are still enormous, though, and I haven't seen a vertical farm that can grow staples like corn or wheat at scale. Can vertical farming really displace conventional farming, or is it just a niche solution for high-value crops?
