Fogponics is an advanced variation of aeroponics where ultrasonic foggers or humidifiers create an ultra-fine nutrient mist (fog) with droplet sizes of 5β30 microns β far smaller than standard aeroponic nozzles. The tiny droplets penetrate deep into root tissue, enabling extremely rapid nutrient absorption and growth.
Key Facts
- Droplet size: 5β30 microns β smaller than aeroponic nozzles (50β100 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 β roots dry out very quickly without continuous fog
