I know this is a meme but actually looking into this is very interesting, the question being answered is "how can we build on distant planets" which scientists from Manchester university have tried to answer with human waste products and space dust. Any food production on a ship will be for consumption so while potato's are a good choice on earth in reality growing potato's on distant planets pose more question than answers.
Human waste products I can understand. But how many humans would you need to mulch to get enough blood for a building project? That’s one of the main fluids we usually want to stay inside our bodies.
We can donate so much a month so a haul to Mars would take years. Also these expedition may get larger with crew capacity.
Its early days yet and this is just one method there will be a dozen more by the time we actually start traversing distant planets.
if for some reason you have overproduction (plague?) nice to know you can make decent bricks out of the food tho
potato plague in space?
yes the potatoes give people plague so you have too many potatoes that could be a reason
