The experiment was conducted by NASA astronaut Jeff Williams on the International Space Station earlier this month.
It was conceived by secondary school students as part of the International Space School Education Trust’s (ISSET) Mission Discovery programme. The programme enables ordinary secondary school pupils to carry out research with NASA Astronauts, rocket scientists and trainers.
Daniel Reid, Daniel Sullivan, Joseph Lynch and Jenna Leigh Morris all took part in ISSET’s programme at the King’s College, London.
Julie Keeble, lecturer in Pharmacology at King’s College, said: "It is incredible to see how much Gro-Sure Fast Acting Lawn Seed has grown aboard the space stations, considering how difficult it is to grow any form of plant within a micro-gravity environment.
"The student’s experiment and has been a great success and we’d like to thank everyone who made it possible."
Daniela Constantine, brand manager for Gro-Sure Lawn Seed said: "We produce GroSure Lawn Seed with a ‘Grow With Certainty’ promise to reassure consumers it will grow anywhere, even in difficult conditions. However, even we didn’t realise it could grow in space."
