Panasonic may be known for its consumer electronics, but the Japanese company is also venturing into indoor agriculture.
In 2014, Panasonic started growing leafy greens inside a warehouse in Singapore and selling them to local grocers and restaurants. At the time, the 2,670-square-foot farm produced just 3.6 tons of produce per year. The farm's square footage and output have both more than quadrupled since then, Alfred Tham, the assistant general manager of Panasonic's Agriculture Business Division, tells Business Insider.
Panasonic's greens are all grown indoors year-round, with LEDs replacing sunlight. The growing beds are stacked to the ceiling in order to achieve a higher yield in the limited space.

The farm's 20 workers put on hairnets, face masks, gloves, and hazmat suits before handling the produce to make sure they don't contaminate it.

The farm potentially produces 81 tons of greens per year at full capacity — 0.015% of all produce grown in Singapore. The hopes to eventually raise that percentage to 5%.

There are currently 40 types of crops in the warehouse, including mini red radish, mini white radish, rocket lettuce, mizuna, Swiss chard, romaine lettuce, and rainbow chard.

To plant the greens, Panasonic's workers place tiny seeds on growing beds. Unlike many vertical farms, Panasonic's grows its greens in soil.

Everything grows under LEDs instead of sunlight. The lights come from a local company and waste less energy than typical light bulbs.

Panasonic's farm likely still has high energy costs, however, since the LEDs are on 24-7. Even the best LEDs have only a 50% efficiency rate, meaning half the electricity is turned to heat, not light, The New York Times reports.
The LEDs shine at a specific frequency that encourages the plants to grow quickly. The farmers also control the warehouse's climate, including its humidity and temperature.

Once the seeds begin to sprout, the farmers transfer the plants to small pots.

The farm's goal is to increase the amount of produce grown in Singapore, which imports over 90% of its food. The island nation has a shortage of arable land, so indoor farming could become a viable way to grow more greens, Tham says.

Each 3-ounce bowl of salad greens from the farm sells for about $5 (USD) in Singapore's grocery stores, under the brand Veggie Life. In mid-2014, Panasonic also started selling greens to local restaurants.

Panasonic's indoor agriculture project is part of its Factory Solutions division, which creates industrial machines and systems. Given the division's experience with engineering and manufacturing, Panasonic sees indoor agriculture as a profitable extension of its business, Tham says.

"We foresee this business to be a potential growth portfolio, given the global shortage of arable land, increasing populations, climate change, and demand for high quality and stable food supply," Tham says.
