Temperature and Humidity: Difference between revisions

Temperature and humidity share a single article as they are so closely linked. Generally, humidity in a growing context refers to [https://en.wikipedia.org/wiki/Humidity Relative Humidity] (RH). As temperature decreases the amount of water vapour itair can hold before itthe water condenses back into a liquid decreases. In other words, hotter air can hold more water vapour per volume than cold air can<ref>https://www.royalqueenseeds.com/blog-indoor-cannabis-growing-relative-humidity-and-temperatures-n243</ref>. In fact, this is the principle that freeze-drying relies on. Temperature and humidity can also be used to calculate the Vapour pressure deficit (VPD) which provides an indication of the cultivar's capacity for [[Plant processes#Respiration|gas exchange]].
