How To Store Cannabis

How to store weed

Figuring out how to store cannabis is important whether you’ve bought it or you harvest the cannabis yourself.

What is the best way to store cannabis?

Cannabis, like dried herbs used in cooking, can lose some of its taste and potency over time. The main goal of cannabis storage is to keep it fresh. You should store cannabis in an airtight container in a cool, dark location. This method should keep your cannabis fresh for up to six months. Vacuum sealing is recommended for longer periods. The primary causes of cannabis spoilage are air, temperature, light and humidity. The best cannabis storage solutions take these factors into account to keep your bud fresher for longer:


You should keep cannabis at a cool temperature. The chemical reactions that cause cannabinoids to degrade at higher temperatures are accelerating. It is also critical to keep cannabis above freezing temperature. While freezing effectively stores most foods, it separates the trichomes from the plant material in cannabis. Cannabis should be stored in a cool cupboard or cold storage area, away from anything that emits heat.


When it comes to humidity, too much and cannabis become moldy or sticky; too little, and it dries out and crumbles. Between 55-62 % is the best range for keeping cannabis fresh but not sticky. This is slightly higher than what is found in most homes (40-50 percent), indicating that it can be useful in controlling moisture levels. It’s critical not to overdo it with the humidity. Mold growth becomes a possibility when moisture levels exceed 60%. In the summer, you will also want to keep the temperature cool to reduce humidity in the air.


Elevated levels of oxygen can hasten the breakdown of cannabinoids and terpenes. When buds are exposed to air, they begin to dry out, and the terpenes, cannabinoids, and other phytonutrients present in the plant material begin to degrade. Keep your stash in an airtight container to protect it from excessive amounts of air.


While cannabis plants flourish on light during their different phases of development, UV rays can degrade your blossoms after harvesting faster than anything else. It is best to keep your stash away from direct light sources to avoid losing valuable terpene and cannabinoid content during storage. If you cannot store your container in a dark environment, use opaque containers or cover any container areas where light may enter with stickers or tape.

How to store cannabis in a freezer or refrigerator?

Wondering how to store cannabis? Refrigerators are a popular but less best method to store cannabis. However, their temperatures and humidity levels can vary greatly, leading to mold or cannabinoid degradation. They are better than leaving your bud on the kitchen counter, but not by much. Because the temperature and humidity rarely vary, most users keep their mason jars in freezers for prolonged storage. However, freezing causes the trichomes to become brittle, and if the jar is not handled carefully, they can fall off. If you are going to freeze your cannabis, be very careful when handling it and make sure to defrost it to avoid ruining your stockpile thoroughly. When storing in the freezer, please allow for 30 minutes or so for your cannabis to come to room temperature before opening the jar.

The best container to store cannabis

Some of the options of how to store cannabis are intended for short-term storage only, while others can handle both long-term and short-term storage. Some of the options of how to store pot also have the added benefit of being odorless! Below are some of the best containers to store cannabis.

Mason jars

As more people began storing cannabis in mason jars, their popularity grew. Mason jars are considered the best way to store cannabis because the hard lid presses against it, keeping the jar airtight and preventing anything from getting in. This is an excellent option if you are looking for the best way to store cannabis. Cannabis stored in airtight glass jars in a chilly, dark place will retain its characteristics for a year or more.

Cannabis humidor

If you have more cash to spend on cannabis storage, you should consider purchasing a cannabis humidor. A humidor is a temperature-controlled box used to store cigars, cigarettes, pipe tobacco, or, in this case, dried cannabis. Use only cannabis-specific humidors; otherwise, the wood used in their construction may compromise your flower.

Vacuum sealing bags

You can store cannabis in vacuum bags to prevent odors from entering or exiting. You should be aware that the vacuuming process will reduce the bud’s quality. The good news is that aroma and fragrance are here to stay. Vacuum sealers come in various sizes and shapes, so you can select the ones you require based on your storage amount. Another advantage of using this method is that it protects your items from mold. Once your goods have been sealed, the best place to store them is in the refrigerator. The freezer is far too cold for storing cannabis.

Frequently asked questions

How to store cannabis smell proof

Most cannabis users, whether medical or recreational, value discretion. There are still many stigmas attached to cannabis, and some medical patients don’t want to advertise this private information to strangers who come into their homes. This is entirely reasonable and understandable. Fortunately, the odor is manageable. Airtight mason jars are the best way to store cannabis, but they aren’t perfect; some scents may still escape. These jars will normally breathe, which isn’t necessarily a bad thing if you are wondering how to store cannabis smell proof.

Does cannabis expire?

Mold is one thing, but what about long-term storage; will your stash go bad eventually? Cannabis, like all organic matter, finally expires or goes bad to some extent. The exact amount of time required varies depending on several factors. Commercially produced derivatives (oils, shatters, and so on) have a shelf life of one to two years. Cannabis buds typically degrade after a few months. Longevity is also affected by the strain and, of course, how it is stored.

How can you tell if cannabis has turned bad?

It is easy to tell when your stash has died. This can be seen in the appearance of the bud and the feel and aroma. If it’s dry and dusty, shows signs of mold or mildew, or has been sitting in a non-airtight container or plastic bag for several years, chances are it has gone bad.
