Zucchini was officially grown in space in 2012. Astronaut Donald Pettit created a blog about growing a space zucchini during Expedition 30/31 on the International Space Station. The zucchini was grown in a plastic bag and nutrient solution. It was not grown using hydroponics; the method of growth was considered to be aeroponics. The medium of transfer was still water, but was in the form of a fine mist, and therefore basically air. This was to reduce a large volume of water from being used. Don’s blog is written from the perspective of the zucchini, and is very poetic. You can read it or listen to it here.
