Here's the real question. Or, can it be made edible? Cultivating something like this on Mars out in the open makes more sense than growing potatoes indoors.
Even if it’s not directly edible it can be a source of amino acids and proteins that could be then processed into something edible or be a source of food for other things that provide better nutritional value to humans like yeast.
The question is it going to be more cost effective than hydroponics.
