Aeroponics (high-pressure)

Bare roots suspended in air, misted with fine droplets of nutrient solution. The fastest growth of any technique, and the least forgiving: minutes of pump or nozzle failure can cost the crop.

Tier 2 with the sharpest edge. Off-grid, solar and battery backup is not optional — and even on mains, this is the technique where the sensor layer earns its keep.
