No. | Parameters | Common value | Instruments |
|
1 | Nutrient atomization | Mist/spray/aerosol/droplet size at high pressure from 10 to 100, low pressure from 5 to 50, and ultrasonic foggers from 5 to 25 microns, respectively | Atomization nozzle (high and low pressure, atomization foggers) |
2 | Growing medium | Plant holder | Any artificial root supporting structure |
3 | Desirable pH of the nutrient solution | The pH value depends on the cultivar (onion 6.0–7.0, cucumber 5.8–6.0, carrot 5.8–6.4, spinach 5.5–6.6, lettuce 5.5–6.5, tomato 5.5–6.5, and potato 5.0–6.0) | pH measuring device |
4 | Desirable EC of the nutrient solution | The EC value depends on the cultivar (onion 1.4–1.8, cucumber 1.7–2.2, carrot 1.6–2.0, spinach 1.8–2.3, lettuce 0.8–1.2, tomato 2.0–5.0, and potato 2.0–2.5 ds·m−1) | EC measuring device |
5 | Humidity | Provide 100% available moisture | Humidity measuring device |
6 | Temperature | Optimum 15°C–25°C and should not increase to 30°C and less than 4°C | Temperature measuring device |
7 | The light inside the box | The light inside the growth box must be dark enough | Cover the growth chamber with locally available material |
8 | Atomization time | Depends on the cultivar growth stage | Manually operating the system with timer |
9 | Atomization interval time | Depends on the cultivar growth stage | Manually operating the system with timer |
