Sure, they are no nonsense, but I guarantee you that there life is more involved than just sticking seeds in the ground.
This reminds me of the difference between US and Russian spacemen. The US has long had the attitude of “replace, not repair”, so much of what they use is modular. The Russians had the opposite policy, so became known among the Americans as being able to fix just about any problem they encountered.
The US space station Skylab operated for under a year. The Soviet space station Mir operated for a decade.
Eventually the two decided to sponsor the International Space Station, which had an American module and a Russian module. In either case, if either module had an emergency, its occupants could safely evacuate to the other module.
