So if and when space gardens have outgrown their primary role as agriculture or a sort of organic HVAC in the early stages of space colonization, and our intrepid colonists attempt a more recreational approach, well, how would they design it when one can float? When a wall is a floor is a ceiling is a floor is a wall in zero gravity. (Except when it’s got a door.) A simple gesture like craning your neck up at a tree may no longer be necessary when it’s a simple skip and a jump to the canopy. A truly three-dimensional space, not just up to 10 feet off the ground.
