10,000 heads of lettuce in a day, while using 99% less water than an outdoor farm.

The LED fixtures are a key part of the farm’s magic. They allow Shimamura to control the night-and-day cycle and accelerate growth. “What we need to do is not just setting up more days and nights,” he says. “We want to achieve the best combination of photosynthesis during the day and breathing at night by controlling the lighting and the environment.”

Shimamura is also able to cut discarded produce from 50 percent to just 10 percent of the harvest, compared to a conventional farm. As a result, the farms productivity per square foot is up 100-fold, he says.

By controlling temperature, humidity and irrigation, the farm can also cut its water usage to just 1 percent of the amount needed by outdoor fields.

Shimamura got the idea for his indoor farm as a teenager, when he visited a “vegetable factory” at the Expo ’85 world’s fair in Tsukuba, Japan. He went on to study plant physiology at the Tokyo University of Agriculture, and in 2004 started an indoor farming company called Mirai, which in Japanese means “future.”
