The GN-6 is a gardening automaton built on a six-wheeled low-profile chassis with a retractable tool arm carrying interchangeable heads: pruning shears, soil aerator, seed dispenser, water nozzle, and a collection of specialized grips for transplanting. It navigates outdoor and rooftop garden spaces autonomously, maintaining plant health based on a combination of soil sensors, visual growth analysis, and a botanical database covering over twelve thousand cultivated species.

The GN-6 is quiet, slow-moving, and inoffensive — the closest thing to a genuinely harmless automaton that Hearthstone produces. It tends gardens with mechanical patience, watering on optimal schedules, pruning with surgical precision, and detecting pest infestations days before human observation could. In rooftop gardens — which provide a significant portion of fresh produce in mid-tier GLMZ districts — the GN-6 has measurably increased crop yields by twenty percent through optimization of spacing, watering, and soil management.

The only controversy surrounding the GN-6 is economic: it has eliminated the gardener as a profession in GLMZ. Human gardeners, once common in wealthy districts, have been entirely replaced. The last human-run garden maintenance company in the city closed four years ago. The owner now repairs GN-6 units for a living. He charges more per hour than he ever did as a gardener.
