Best Temperature & Humidity for Weed Storage

When you track down your favorite strains, it’s natural to want to stock up. However, if your weed is not properly stored, your investment can quickly turn into a flavorless, less potent thing that barely resembles what you purchased from the dispensary. There are several factors that affect how long weed stays fresh, but the most important two are temperature and humidity.

Breaking down the best temperature and humidity for weed storage…


The best temperature for storing weed is between 60 and 68 degrees Fahrenheit. However, you can get away with temperatures as low as 50. Most people keep the interior of their homes at temperatures close to this range, but finding a cool spot away from sunlight in the house is always recommended.


The best humidity for weed storage is between 55 and 65 percent. For reference, the average acceptable humidity level inside a typical, air-conditioned home is between 30 and 40 percent, which is too dry to keep weed fresh. Humidity pack solutions like the Evergreen pod can help you achieve this optimal humidity range in your stash jar.

Why do humidity and temperature matter when storing weed?

When cannabis is harvested, growers go through a painstaking process to cure the buds to retain optimal quality and longevity. For example, some growers use a process where buds are kept at about 64 degrees Fahrenheit with humidity levels between 45 and 55 percent for a few weeks. This encourages moisture levels in the plant to drop to about 5 to 10 percent by the time the cannabis is tucked into a package for sale. 

Temperature and humidity play key roles in the curing process, so they naturally play a role in keeping the cannabis fresh after being cured.  High temperatures can cause decarboxylation of cannabinoids, which means the cannabinoids present turn into something else. Low temperatures can cause damage to the trichomes, which is one reason storing weed in a freezer is a bad idea. High humidity can contribute to mold on your weed, and low humidity causes the terpenes and cannabinoids to evaporate.
