Claim · model-written summary
Reduced VPD caused a decrease in canopy transpiration greater than the decrease in fog evaporation.
Solanum lycopersicumVerbatim
e0“The decrease in canopy transpiration resulted from the decrease in VPD, and was at a magnitude greater than that of the fog evaporation rate under similar experimental conditions with relatively high humidity in the range of 70-94%”
e1“The tomato plant canopy transpiration rate”

- Intervention effect Fog cooling used less water than pad-and-fan cooling.
- Intervention effect Air relative humidity was slightly higher with fog cooling than pad-and-fan cooling.
- Association Simulated greenhouse air relative humidity declined with increasing ventilation rate.

- Method / resource The control algorithm could maintain humidity and temperature in a desirable range while reducing fog water use.
- Association Tomato canopy transpiration increased linearly with vapor pressure deficit.
- Intervention effect Lower ventilation decreased total greenhouse water use by 13%.
