Toshiba’s high-tech grow rooms are churning out lettuce that never needs washing

Dan Frommer in Quartz:

Toshiba, the Japanese technology conglomerate with a lineage dating back to the 19th century, is looking for growth in a whole new way. In a sterilized clean room about 35 miles outside of Tokyo, where Toshiba used to make floppy disks in the 1980s and 90s, the company is now starting to grow thousands of lettuce plants as it expands into indoor agriculture.
