Freight farms, a shipping container farm company, specialises in sustainable farm systems built inside portable shipping containers. The so-called Leafy Green Machines (LGMs) are outfitted with LED lighting that replicates sunlight, a drip irrigation system that uses just ten gallons of water a day, and sensors that balance temperature, humidity and carbon dioxide levels.
Crops such as lettuce and kale are grown in vertical towers to avoid wasted space and ensure the maximum possible yield. Freight Farms is a much more efficient use of land, growing vertically in a very condensed footprint. The farms can yield the equivalent of two acres of conventional farmland. The farms also don’t require a great deal of expertise or in-depth training to run.
