World’s Largest Indoor Farm is 100 Times More Productive

The statistics for this incredibly successful indoor farming endeavor in Japan are staggering: 25,000 square feet producing 10,000 heads of lettuce per day (100 times more per square foot than traditional methods) with 40% less power, 80% less food waste and 99% less water usage than outdoor fields. But the freshest news from the farm: a new facility using the same technologies has been announced and is now under construction in Hong Kong, with Mongolia, Russia and mainland China on the agenda for subsequent near-future builds

Indoor Factory Lettuce Farm.

In the currently-completed setup, customized LED lighting developed with GE helps plants grow up to two and half times faster, one of the many innovations co-developed  in this enterprise by Shigeharu Shimamura, the man who helped turn a former semiconductor factory into the planet’s biggest interior factory farm.

The specific idea to deploy it at this time and in this place grew out of a disaster: the 2011 earthquake and tsunami that shook the island nation, causing area food shortages in general and this building to be abandoned in particular. Turning it into an indoor farm both gave the structure a new purpose and has helped replace needed fresh, healthy and locally-grown greens.

Shimamura has shortened the cycle of days and nights in this artificial environment, growing food faster, while optimizing temperature, lighting and humidity and maximizing vertical square footage in this vast interior space (about half the size of a football field). No water is lost to soil and a core-less lettuce variant reduces waste.

 Indoor Future Led Farming

Currently, the process is “only half automated. Machines do some work, but the picking part is done manually. In the future, though, I expect an emergence of harvesting robots. For example, a robot that can transplant seedlings, or for cutting and harvesting, or transporting harvested produce to be packaged.”

Factory Farm Indoor

Shimamura continues to think about future refinements, applications and expansions: “I believe that, at least technically, we can produce almost any kind of plant in a factory. But what makes most economic sense is to produce fast-growing vegetables that can be sent to the market quickly. That means leaf vegetables for us now. In the future, though, we would like to expand to a wider variety of produce. It’s not just vegetables we are thinking about, though. The factory can also produce medicinal plants. I believe that there is a very good possibility we will be involved in a variety of products soon.”The beauty of this development lies partly in its versatility – since it deals in climate-controlled spaces and replicable conditions, a solution of this sort can be deployed anywhere in the world to address food shortages of the present and future. Saving space, indoor vertical farms are also good candidates for local food production in crowded and high-cost urban areas around the globe. Aforementioned strides in waste and power reduction also make these techniques and approaches far more sustainable and cost-efficient.
