Absolute Humidity is the actual water vapor content in air, expressed in g/kg or g/m³.
Absolute Humidity (AH)
Short definition
Expanded definition
The absolute humidity (AH) of air is the actual water vapor content in g/kg or g/m³. It can also be expressed as water vapor pressure in kPa.
In Greenhouse Context
Absolute humidity helps determine how much moisture is present in greenhouse air, crucial for climate control and plant health.
Examples and/or use cases
Monitoring AH helps optimize dehumidification and avoid fungal diseases in crops like tomatoes and cucumbers.
Relevance
Precise control of AH is vital for managing plant transpiration, disease prevention, and ventilation strategy.
