Indoor farms and rooftop greenhouses are hitting new economic and environmental pressure points, and the latest stats make the tradeoffs hard to ignore. Vertical farming alone is estimated at $77.1 billion in global revenue for 2021, while hydroponics is valued at $3.4 billion in 2022, yet the economics can hinge on electricity and lighting, where costs frequently dominate operating budgets. At the same time, shoppers signal real willingness to support local produce and many controlled-environment systems can deliver leafy greens on a tight harvest to shelf timeline.
