주요 사실

• Droplet size: 5–30 microns — smaller than aeroponic nozzles (50–100 microns)
• Ultra-fine fog penetrates root hairs directly, maximising absorption efficiency
• Ultrasonic foggers are inexpensive but can deposit mineral salts and overheat reservoirs
• High-pressure fogponics uses specialised atomising nozzles for commercial-scale operation
• Produces some of the fastest root development observed in soilless systems
• Sensitive to power interruptions — roots dry out very quickly without continuous fog
