AMES, Iowa (AP) — Ames indoor farm Nebullam has rebranded as Clayton Farms as it expands to the Twin Cities and sets its sights on eastern Iowa and beyond.
Vertical farms stack rows of plants on top of each other. Those indoor farms control the lighting, water and temperature to create ideal conditions to grow fresh produce year-round close to customers. But the industry relies on artificial lighting and has a large carbon footprint.
