An old Toshiba factory has been remodeled as a 'germ-free' indoor farm for salad leaves

The Toshiba Clean Room Farm in Yokosuka used to be a 21,000-square foot electronics factory before becoming an isolated tank that could grow nearly $3-million of leafy vegetables per year.

The indoor farm will be isolated from the environment. Indoor air quality will be closely monitored, with temperature and moisture precisely maintained. High-tech lighting systems will put in place to substitute the sun. Also, all personnel will wear protective clothing when coming in contact with the plants. The goal? To keep the plants as free from bacteria, fungi and insects as possible.
