Best Answer: With all other things remaining the same, relative humidity will increase as temperatures decrease. Since relative humidity is a ratio (in percent) of the actual amount of water vapor in the atmosphere compared to the saturation amount, if the saturation amount decreases, the ratio must increase.

Humidity is actually a measure of how much water vapor is being âheldâ in the air. There are different ways to measure humidity, including absolute, specific, or relative humidity. Most growers are talking about Relative Humidity or RH when they talk about humidity in the grow room.Relative humidity measures how much water is in their air compared to the maximum amount of water that can be held in the air at that temperature.elative humidity is measuring how much water is âbeing heldâ in the air compared to the maximum amount of water that can be held at that temperature. Warm air can âhold ontoâ more water than cool air. Plants will tend to thrive at different relative humidities depending on the temperature of the air.
