Good
answer! About 50 square meters of crops can produce enough
food to support one astronaut. A crew of three would need 150
square meters of hydroponic gardens&emdash;enough to fill a 3-bedroom
house! Fortunately, those same plants will also recycle oxygen for
astronauts to breathe.
What you eat is almost as important as how much you eat. What would be some good crops for your hydroponic garden?
Pick the best four!
