Inside the International Space Station Environmental Simulator chamber the bellows has been removed.

Inside the International Space Station Environmental Simulator chamber at the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the bellows has been removed from around the Veggie plant growth system so that the plant pillows containing the outredgeous red lettuce leaves can be removed. The growth chamber was used as a control unit and procedures were followed identical to those being performed on Veggie and the Veg-01 experiment on the International Space Station.

The chamber mimicked the temperature, relative humidity and carbon dioxide concentration of those in the Veggie unit on the space station. Veggie and Veg-01 were delivered to the space station aboard the SpaceX-3 mission. Veggie is the first fresh food production system delivered to the station. Six plant pillows, each containing outredgeous 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 33 days. On June 10, at the end of the cycle, the plants were carefully harvested, frozen and stored for return to Earth by Expedition 39 flight engineer and NASA astronaut Steve Swanson.
