A Scientist Is Growing Asparagus In Meteorites To Prepare Us For Space Farming

Jason Koebler writes: For those of us without a green thumb, growing even the most hardy plants in perfect conditions can seem impossible. How about trying to grow plants on a meteorite? Well, at least one scientist is doing it, with moderate levels of success. "People have been talking about terraforming, but what I'm trying to do is give some concrete evidence that it's possible to do this, that it's possible to grow in extraterrestrial materials," Michael Mautner, one of the world's only "astroecologists" said. "What I've found is that a range of microorganisms—bacteria, fungi, and even asparagus and potato plants—can survive with the nutrients that are in extraterrestrial materials."

Small Question

How big of an meteorite would one need for a valid proof of concept? Also, in order to create atmosphere, a large shake and bake bag of CO2 for said meteorite? Can the roots grab hold onto said meteorite? Maybe a bit celophane tape to hold the seeds on the meteorite till the roots take hold?

I know how stupid this is going to sound; but couldn't one test this out by taking a large meteorite fragment up to the ISS and test there? I know what I just said.
