The dew point is an absolute measure of water vapor in the air.

As temperature changes, the amount of water the air can hold changes. Hotter air holds more water while colder air holds less. As the temperature goes up, the relative humidity decreases — and you effectively reduce the risk of condensation. 

By controlling the moisture levels and temperature of your grow room, you'll keep your crops safe from serious problems like bud rod, mold and mildew, as well as equipment failure.
