Preparing the Greenhouse Dew Point Margin values
Prepare Air temperature and Dew point for Greenhouse Dew Point Margin. Keep unrelated records separate. Ideal exchange time is available from Greenhouse Air Exchange Time Calculator.
- Air temperature. Its Greenhouse Dew Point Margin demonstration rate is 68 °F.
- Dew point. Default in Greenhouse Dew Point Margin: 58 °F.
Formula for dew point margin
Greenhouse Dew Point Margin finds the difference using Air temperature and Dew point. Temperature margin also belongs in Cold Frame Temperature Margin Calculator.
Using air temperature at 68 °F and dew point at 58 °F, the example returns 10.00 °F and 17.2%. Water volume per degree? See Greenhouse Thermal Mass Water Calculator.
Greenhouse Dew Point Margin in practical terms
Greenhouse Dew Point Margin focuses on Dew point margin and combines Air temperature and Dew point.
Use dew point margin to measure the temperature margin above dew point, then inspect air temperature in the field.
Collecting data for Greenhouse Dew Point Margin
Recalculate after changing a covering, setpoint, ventilation rate, crop load, or equipment capacity. The related Row Cover Temperature Gain Calculator finds estimated covered temperature.
Interpreting this dew point margin value
Greenhouse Dew Point Margin summarizes its formula as Dew point margin.
Margin relative to dew point supplements dew point margin in Greenhouse Dew Point Margin.
How input changes affect dew point margin
If Dew point changes during the season, calculate a new scenario instead of adjusting dew point margin mentally.
Greenhouse Dew Point Margin beyond the formula
Cold leaf and glazing surfaces may condense before room air.
Dew point margin questions
How does “Cold leaf and glazing surfaces may condense before room air.” affect dew point margin?
Account for it in the source measurement for air temperature; the formula has no additional correction for it.
Can Greenhouse Dew Point Margin guarantee field or greenhouse conditions?
No. The dew point margin value reflects the entered dates or readings. Confirm it with a current forecast or sensors positioned near the crop.
