I'm writing the story for a game I'm making. I've got an underground farm powered by artificial lights. I was wondering which crops would be best as a food source and for efficiency. I've done my own research and have come up with quinoa, but I was wondering if anyone else had input. Thanks, also please give sources.
Edit: This is for a civilisation with a light source! So please don't mark this as a duplicate of that other question. That deals with a completely dark civilisation. This is asking for a crop that is space efficient and that one can survive on with little other food sources.
