How it affects the system
- Highest possible root oxygenation: roots are continuously misted then exposed to humid air, producing fastest growth rates of any hydroponic method when run correctly
- Pump failure or clogged nozzles kill plants in minutes to hours: no buffer reservoir, no medium moisture
- Calibration-sensitive: droplet size 30-100 microns is the standard for high-pressure aeroponics; outside that range performance falls off
- Difficult retrofit: most hobbyist aeroponic setups are purpose-built tower or chamber systems, not adapted from other hydroponic methods
System compatibility
Works well in:
- aeroponic
Avoid in:
- media bed (ebb and flow)
- NFT channels
- deep water culture (rafts)
- drip
- wicking bed
- soil bed
Care notes
Currently not a supported system in the garden planner because it sits outside the dwc/nft/vertical/drip/media-bed/wicking/soil-bed enum. Listed here as reference material; future planner work may add aeroponic as a system option. Realistic for advanced hobbyists with a high-pressure pump, accumulator tank, and timer-controlled solenoids.
