World’s largest productive indoor farm

Japan is very well known country for incredible inventions always. Now they came with this indoor farming technique, the efficiency and yield of these farms is just shooting through the
An area of 25,000sq.ft. is producing a whopping 10,000 heads of
lettuce on daily basis while consuming less than 40% power consumption,
80% less food wastage and 99% less than water usage when compared with
conventional fields. This yield is a hundred times higher (per square
foot) when looked at comparison in outdoor fields.

The advantages of indoor farming where one can control the climate are
quite obvious; the crops don’t get affected by any weather interactions, crop
disease or even droughts and everything goes as planned.

Japanese plant
physiologist Shigeharu Shimamura working in Miyagi Prefecture in eastern
Japan following a powerful earthquake incident and tsunamis in 2011
transformed the semiconductor factory (previously owned by
Sony Corporation) into the world’s biggest indoor farm that was
illuminated by LEDs. The LED fixtures were a courtesy of GE and the
light being emitted had been modified so that it was emitted at
wavelengths that is considered optimal for plant growth.

Shimamuarsaid, “I knew how to grow good vegetables biologically
and I wanted to integrate that knowledge with hardware to make things
happen. What we need to do is not just setting (sic) up more days and
nights. We want to achieve the best combination of photosynthesis during
the day and breathing at night by controlling the lighting and the

These LED lights also allowed the team to control humidity,
temperature and irrigation, thus reducing the water consumption by 99%
while also managing to grow these crops 2.5 times faster. The GE Japan
team is hopeful that indoor farms such as the one located in Miyagi
Prefecture can prove to be a viable solution when it comes to battling
food shortages in world. Miraj and GE are working on ‘plant factories’
in Hong Kong and in eastern parts of Russia. Shimumara said, “Finally,
we are about to start the real agricultural industrialization.”
