Nimble Farms’ modular, climate-controlled grow units are housed in converted shipping containers. Designed to maximize productivity per square foot, each unit is equipped with energy-efficient LED lights, recirculating water and nutrient systems, and precise environmental controls. The company says this setup optimizes inputs such as fertilizer, water and energy, enabling year-round production of a wide variety of crops, including living lettuces, herbs, microgreens and mushrooms. All Nimble Farms sites are powered 100% by renewable energy sourced from local solar, wind and hydroelectric power.

The company collaborates closely with local supermarkets, farmers’ markets, schools and hospitals across New York State and the broader Northeast region to meet the growing demand for local, perishable produce.
