Space food control experiment for the ISS. Researchers documenting the ground control plant pillow experiments for an experiment taking place on plant growth on the International Space Station (ISS). This is part of the Veggie plant growth system inside a control chamber at the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, USA. The growth chamber is being used as a control unit and procedures are being followed identical to those being performed on the Veggie and the Veg-01 experiments on the ISS. Veggie is the first fresh food production system delivered to the ISS. Six plant pillows, each containing red romaine lettuce seeds and a root mat, were inserted into Veggie. The plant chamber's red, blue and green LED lights were activated. The plant growth was monitored for 28 days. At the end of the cycle, the plants were carefully harvested, frozen and stored for return to Earth. Photographed in May 2014.
