Includes All the Air Available to the Crops being Cultivated within a Grow Room.
To understand more complex environmental values Temperature and Relative Humidity can be Apllied to a Psychrometrics Chart, to Determine Important Parameters Related to the Moisture Content of the Air surrounding the crops being produced.
The mixture of air and suspended moisture within the grow facility is known as the Gas-Vapor Mixture.
The temperature of the air within a grow room greatly influences the amount of moisture (water) that can be dispersed into the air.
Higher Temperatures = Higher Moisture Capacity
Lower Temperatures = Lower Moisture Capacity
Temperature Fluctuation can Lead to Dramatic Increases or Decreases in (RH%):
During Evenings | Temperature Drops & (RH%) Similtaneously Increases
During Mornings | Temperature Rises & (RH%) Similtaneously Decreases
Moisture Content of in the Air Surround the Crops being Grown. Greater facility Humidity results in High Concentrations of water in the Air.
Humidity Can Be Defined in (3) Ways:
Specific Humidity | Absolute Humidity | *Relative Humidity*
The First (2) Deal with Ratios of Water Vapor (Moisture) Mass.
Relative Humidity (RH%) on the other hand can be measured using a digital sensor, which is why it’s so commonly utilized over the first (2)
*Realtive Humidity* (RH%) is Expressed as a Percentage of the Max Moisture the Air can Hold Before Condensation Occurs at a Particular Temperature
More Specifically it is Measured as the Ratio of the Vapor Pressure of Moisture in a Sample to the Saturation Vapor Pressure of the same Sample at the Dry Bulb Temperature
