How to Store Hemp Flower

Storing hemp flower in a glass jar

Whether you just harvested your own crop or bought a good quantity of your favorite bud, you should know how to store hemp flower since it can make a big difference in how the buds preserve their terpenes when stored for a long time.

Some factors such as exposure to air, harsh light, and humidity conditions can significantly alter the quality of your buds as time passes. When storing CBD flower for a long time, it is essential to consider all these factors and even choose the proper container to store your buds as some materials under certain conditions can alter the taste and smell of your herb. In this article, we will talk in more detail about the factors that influence hemp flower storage, the best ways to store your weed, and some pros and cons of the most popular hemp containers used today.

Things to Consider When Storing Hemp Flower

As we already mentioned, several factors can affect the quality of your buds when they are stored, especially if you have a large amount of weed to store or plan to keep it for a long time. The main factors to consider are:


As you surely know, the buds go through a drying and curing process before they can be consumed or reach the shelves of dispensaries. Keeping the hemp flower at the right temperature will prevent mold or mildew from forming. 

Another compelling reason to take care of the temperature at which you store hemp flower is that the cannabinoid content of your buds could degrade depending on the temperature. Some may think that the curing process ends once the hemp gets on the shelf, but it doesn’t work that way. 

Very high temperatures could degrade the cannabinoids in your CBD flower and overdry the buds, affecting their quality and, in turn, causing harsher smoking. Most cannabis connoisseurs agree that an ideal temperature for storing your buds is between 77 ° to 86° F, as it will prevent any adverse changes in the humidity level within the bud leaves.


Humidity is also one of the most important factors to consider for long-term storage, as improper humidity conditions can accelerate mold growth. The hemp flower should retain 59 to 62% moisture. A correct humidity level will help your hemp preserve better by creating a small protective layer of moisture or “terpene shield” over the terpenes and cannabinoids in the buds. This thin layer of humidity over the bud results in better preservation of smells, flavors, and effects. 

Aware of this, Boveda and Integra developed small humidity packs at 59 and 62% to help maintain an adequate level of humidity within the containers in which people often store hemp. Although these moisture packs are not a mandatory requirement to conserve moisture in your buds, they can go a long way in helping you keep your weed fresh until you are ready to use it.

Some people use digital hygrometers to more constantly monitor stored hemp. Hygrometers are devices that help measure the level of humidity in the air where they are. Some hygrometers can be pretty practical and helpful when checking your hemp containers’ moisture levels. There are even some hygrometers small enough to fit inside some containers along with your buds. So, with so many tools and gadgets available, being aware of the humidity levels in which you keep your buds will mostly depend on you.

Light conditions

As incredible as it may sound to some, the light conditions to which your CBD flower is exposed can significantly influence the quality. Keeping an eye over the light conditions is vital because hemp flower, when exposed to UV rays from sunlight or embracing light sources, undergoes a series of reactions and chemical processes that degrade and dilute the terpene and cannabinoid profile content of the buds. This degradation translates into reduced quality buds and diluted smells and flavors. 

Store your hemp flower in cool, dark places like cabinets, cupboards, or drawers. In the case of canna-oil, it is a bit different. Your refrigerator is the perfect place to store cannabis-infused oil since it will help the oil to remain stagnant, avoiding unwanted reactions that could alter the chemical composition of your CBD oil.

Best Hemp Flower Containers

There are endless containers available online made from just about any material you can imagine. However, it is essential to be careful when choosing the container in which you plan to store your hemp flower, especially if it will be long-term storage. Materials such as plastic and some metals can release gases that can compromise or even completely alter the taste of your buds.

Next, we will name some of the most popular containers today, and we will point out some pros and cons of these so that you can make the best decision based on your possibilities.

Glass jars

Glass jars are among the most popular options used by cannabis connoisseurs around the world. Especially mason jars because of the clasp on the top that helps keep the jar airtight. 

  • Pros: Glass is nonreactive, recyclable, almost infinitely reusable if you don’t break it; it can be sterilized with heat and doesn’t give off noxious fumes.
  • Cons: Glass can break easily if you drop it, and if it’s not a mason jar, it will probably not retain a stable moisture level. Translucid glass doesn’t protect the buds from UV light which can cause a quality reduction of your hemp flower.

Plastic vacuum-sealed jars

Plastic vacuum-sealed jars can also be a good option to store hemp flower. Although they may not be the most recommended option for long-term storage, an old vacuum-sealed plastic jar will surely do a good job. Below are some factors that we consider vital to consider when choosing vacuum-sealed plastic jars to store hemp flower.

  • Pros: Plastic jars can be practical and get you out of a bind. You could use almost any plastic jar you have available and vacuum-seal it using a vacuum sealer. If the plastic is colored or dark, it will protect the buds from sunlight damage.
  • Cons: when exposed to sunlight or temperature changes, plastic can release gases and chemical compounds harmful to health. When you expose your buds to plastic, it can alter the smell and even the final taste of your hemp flower, especially if you expose them to plastic for too long. Moreover, if your plastic jar is not vacuum sealed, it probably won’t retain moisture in it, and if the plastic is translucent, it won’t protect your buds from damage caused by sunlight.

Smell-proof bags

Reusable odor-proof bags can be of great help also at times when you have to store hemp flower. However, plastic bags are in a controversial zone. They are among the most popular and used options worldwide, but any cannabis connoisseur will know that it is not the most reliable option when storing hemp for a long time. Let’s go over the pros and cons of this type of container to get a better view of the big picture.

  • Pros: They have a significantly longer shelf life than a regular plastic bag and can be of great help if you’re trying to hide the intense smell that terpenes emanate from your buds. They can be quite practical and manageable and, depending on the material, considerably resistant. Some reusable smell-proof bags are made of non-translucent materials, which will protect the buds from light degradation.
  • Cons: As we already mentioned, plastic can release harmful gases when exposed to changes in temperature or humidity. These toxic gases, in turn, can alter the taste or smell of hemp, compromising its quality. Some plastics are more permeable than others, so it is not a good material when it comes to protecting your buds from exterior conditions.

Regular zip-lock bags

Without a doubt, we reached one of the milestones of cannabis containers around the world. Hollywood and pop culture have been widely popularizing this storage method that, despite controversy and expert warnings, people continue to embrace as one of the first options for storing cannabis. Let’s go over the advantages and disadvantages of using regular zip bags to store hemp flower.

  • Pros: They are one of the most practical and handy options that you can find. Indeed you will have a Zip bag somewhere in your house. They are easy to carry and you can store them practically wherever you want. Their malleable shape makes them easy to store even in difficult places.
  • Cons: plastic bags are easily damaged or torn. Small holes may appear in the bag, allowing outside air to enter, altering the humidity levels inside the bag. A plastic bag, in short, can create a hostile environment for your CBD flower, which is relatively delicate in itself.


A humidor is a closed container, usually made of wood, that carries a humidification system. Initially, humidors were used exclusively for tobacco or cigars. Nonetheless, with the growth of the cannabis industry, especially in recent years, this has changed. Maybe it can be a somewhat elaborate option and not so common, but it can be quite effective. Let’s take a look at the pros and cons of a humidor when it comes to storing hemp flower.

  • Pros: The humidor uses a hygrometer to measure the humidity level inside, and most humidors already come with a built-in hygrometer. You can store hemp flower almost indefinitely by maintaining a good level of humidity inside the humidor. They can look quite elegant in your living room or bedroom while serving a vital function, preserving your cannabis.
  • Cons: Humidors can be somewhat expensive or inaccessible for some users. They can be impractical due to their large size and very little portability. Generally, it will require considerable storage space. Finally, since it is not specifically designed for storing cannabis, storing your buds in a humidor can be disastrous.

Dark containers

Whether made of glass, metal, wood, or plastic, a dark container will always be a good option to store your hemp flower. There are many types of dark materials that you can choose from. Simply use the one closest to you or the one you consider to be the best option depending on how long you plan to store your cannabis. Let’s look at the pros and cons of choosing a dark container to store your hemp flower.

  • Pros: Regardless of the material you choose, if it is dark, you have the upper hand as an opaque container will protect your buds from the damage that exposure to hot light sources or sunlight can cause. Besides, a dark container is an excellent option for storing your hemp when you need to be discreet.
  • Cons: Although it is an advantage, the fact that you use a dark container does not ensure proper storage of your herb. If your container cannot maintain the correct humidity level or does not protect your buds from the outside air, the fact that your container is dark will be of little or no importance. Another disadvantage of using a dark container is that it will not allow you to see its contents, which can be a bit annoying when checking the conditions of the material inside the container.
