(illustration of humidity temperature relation)
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 it can hold before it 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 to the cultivar's capacity for [[Plant_processes#gas_exchange|gas exchange]].
