After the Great Earthquake that Japan experienced in 2011, it has repurposed a Sony Corporation semiconductor factory located in the northeast region’s Miyagi Prefecture and turned it into the world’s largest indoor farm illuminated by LEDs. General Electric reports that they developed the LED fixtures which emit light at wavelengths optimal for plant growth used in the indoor farm.
Another company involved in the project, Mirai Co., based in Tokyo, runs vegetable growing factories. This new growing indoor plant operation is on about 2,300 square meters of land and is able to produce 10,000 heads of lettuce plus other vegetables per day. The produce will be sold to local supermarkets.
The hope is to build more factories similar to this one in other parts of Japan. The LED lights reduce electricity consumption by 40 percent as compared to fluorescent lighting and can use spectrum specific light for optimal growing of the vegetables.
The combined venture further intends to export produce to other nations as well as export the entire growing factory set ups and technology. They have already received requests to do so.
