Recommendations
- Maintain current conditions
- Keep 3°C above dew point
- Continue monitoring changes
What is Dew Point?
Dew point is the temperature at which air becomes saturated and water condenses into liquid.
When surfaces are colder than the dew point, moisture forms - leading to mold, mildew, and plant problems.
Keep grow room temperature 3-5°C above dew point for safety
Formula
Magnus-Tetens:
γ = (a×T)/(b+T) + ln(RH)
Td = (b×γ)/(a-γ)
a=17.27, b=237.3
