Regolith simulants have arrived! Time for some plant growth experiments!
@Zuph @InvaderXan cool, are they sterile?
@ewok @InvaderXan not as-is, although the exolith lab suggests they can be autoclaved. The Martian simulant also doesn't have perchlorates.
I'm not going for something too strictly controlled here, though. This is mostly a small side project.
