I have green fingers and love potting seeds, so I'd definitely have a go with seeds from space!
Soon, British astronaut Tim Peake is taking millions of seeds to the International Space Station. When he returns he'll give them to 10,000 schoolchildren to plant and compare the sprouting space plants with normal plants. Hopefully it will show if being in space affects the seeds' success. Maybe astronauts could grow their own food up there.
This makes me think we're searching for ways to live on other planets. I worry we're giving up on Earth too soon.
