Hemp uses less water no herbicides or pesticides. The first diesel fuel was made from oil pressed from hemp seeds. It’s non-toxic, a nitrogen fixer, grows well nearly everywhere, a renewable resource, makes food, fuel, paper, rope, medicine, cosmetics, plastic, housing and much more.
Growing hemp in space will also ensure less resources are used from asteroids so all the resources won’t eventually be all exhausted. Instead of wasting the water in the asteroid belt on fuel the water could be saved and used to sustain civilizations for an extended period of time.
