Aeroponic
Aeroponic cultivation is a soilless system in which plant roots are suspended in an enclosed chamber and intermittently misted with a fine nutrient-solution aerosol, maximizing root-zone oxygenation and eliminating the substrate entirely. High-pressure aeroponics (HPA) produces droplets ≤50 μm at 80–120 psi, optimizing ion uptake kinetics; low-pressure systems use 100–200 μm droplets. ⚠️ Framework note: under some taxonomic frameworks aeroponics is classified as a distinct modality, while under others it is treated as a specialized subset of hydroponics because the nutrient delivery medium remains an aqueous solution (Resh 2013; Zheng 2021). Aeroponic cannabis production is capital-intensive and unforgiving of pump failures (roots desiccate within minutes) but can produce exceptionally dense root architectures and rapid vegetative growth. Etymology: Greek aer ("air") + ponos ("labor"); coined by F. W. Went, 1957. Synonyms/slang: aero, HPA, fogponics (ultrasonic variant). → See also: Hydroponic, Coco coir, Indoor.
