Humidity is the amount of water vapor in the air. Too much or too little humidity can be dangerous. For example, high humidity combined with hot temperatures is a combination that can be a health risk, especially for the very young and the very old. Humidity plays an important role in our daily weather.
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.
