Storing weed correctly is crucial for preserving its quality, flavour and potency over a longer period [1]. Proper storage can make all the difference between a fresh, aromatic product and one that has lost its best characteristics. Correct storage ensures not only that the cannabis retains its effectiveness, but also that it can preserve its unique aromas and flavour profiles.

How do you store cannabis correctly?

Cannabis is best stored airtight, dark and cool at 15 to 21 degrees and a humidity of 55 to 62 percent. Use a jar with a screw-top lid instead of a plastic bag, store it away from light in a cupboard and keep the flowers away from heat sources. This keeps the aroma, consistency and active ingredients stable for months.

The basics of storing cannabis

Storing cannabis requires careful attention to various factors in order to preserve its quality and potency over the long term [1]. It is essential that cannabis is kept in a dark place that is protected from light, air, moisture and extreme temperature fluctuations. UV light is known to break down cannabinoids and can therefore reduce the potency of the cannabis [1]. Oxygen accelerates the oxidation process, which contributes to the breakdown of terpenes and can impair the aroma and flavour [1]. An imbalance in moisture can also have serious consequences: too much moisture encourages the growth of mould and bacteria, while too little moisture causes the flowers to dry out and lose flavour [1]. Furthermore, extreme temperatures can negatively affect the quality of the cannabis by altering the chemical properties of the flowers [1]. It is therefore of the utmost importance to create the right environment for storing weed in order to preserve its quality and potency as well as possible.

New regulation in Germany from April 2024:

From 1 April 2024, a new legal framework for handling cannabis will apply in Germany. This change provides for the legalisation of the possession of up to 25 grams of cannabis for personal use as well as the cultivation of up to three cannabis plants. In addition, communal cultivation in so-called cannabis clubs will be possible under strict conditions. For more information, please visit the official page of the German Bundestag.

The ideal way to store cannabis

For optimal cannabis storage, airtight glass containers that are protected against UV rays are the preferred solution [1]. These special containers effectively shield the cannabis from light and air while allowing precise moisture control. To ensure the best possible storage conditions, these containers should be kept in a cool, dark cupboard or drawer to protect the cannabis from harmful light exposure and heat. The recommended storage temperature is ideally between 15 and 21 degrees Celsius to ensure optimal freshness of the cannabis flowers [1].

Controlling humidity

Another important aspect of storing cannabis is controlling the humidity. A constant relative humidity of 59-63% is crucial to support the quality of the cannabis and to counteract the risk of mould formation [1]. Humidity-regulating packs are one way to maintain these optimal conditions inside the storage containers. These packs help to stabilise the humidity and keep the cannabis fresh, so that you can enjoy it at any time.


Preventing odour from spreading

Cannabis can give off a strong odour that you may want to minimise. Using airtight containers is an effective method not only to counteract the loss of terpenes, but also to securely contain the smell [1]. These containers provide a reliable barrier against the spread of odour and thus ensure discretion and privacy. For additional odour control, you can keep the airtight containers in resealable bags or boxes to make sure the smell stays under control during transport or storage as well [1]. These measures can help to keep the intense smell of cannabis from reaching your surroundings and to maintain discretion.

A practical tip for home: "burping"

A simple but effective method to improve air circulation in your storage containers and let out excess moisture is what is known as "burping" [2]. Simply open your airtight containers, such as airtight glass jars, mason jars, vacuum jars or special cannabis storage tins, for a few minutes each day to let in fresh air and regulate the moisture. This simple step can help prevent mould formation and promote even fermentation or drying [2]. Remember to properly reseal your containers after "burping" to maintain the appropriate storage conditions.

Long-term storage

If you want to store cannabis for the long term, freezing can be a suitable option, provided you follow certain conditions. Before freezing the cannabis, it is important to dry it thoroughly to counteract the build-up of moisture and the associated mould formation [3]. You can then freeze the dried cannabis in a vacuum-sealed bag. Under these conditions, cannabis can be stored for several months to years [3]. The low temperatures counteract the breakdown of cannabinoids and terpenes, while the vacuum seal can prevent air from getting in, which can result in a longer shelf life [3].

Regular checks

Regardless of the storage method you choose, it is important to check your cannabis regularly for mould and moisture. By inspecting your cannabis at regular intervals for changes in smell, appearance and consistency, you can identify potential problems early on. If you notice unusual changes, such as an unpleasant smell, discolouration or signs of moisture, it is advisable to review the storage conditions and adjust them if necessary. You may need to change the storage location or control the humidity.


By following these guidelines, cannabis consumers and patients can help keep their cannabis fresh. By paying attention to your cannabis regularly and adjusting the storage conditions accordingly, you can make sure that you can always enjoy a product that keeps well.

Frequently asked questions about cannabis

Storing cannabis correctly is crucial for preserving its quality, flavour and potency over a longer period. Proper storage protects the cannabis from harmful light, air, moisture and temperature fluctuations, which can accelerate the breakdown of cannabinoids and terpenes.

Storing cannabis requires avoiding UV light, regulating humidity and maintaining a constant temperature. Airtight, UV-protected glass containers are ideal for shielding the cannabis from light and air, while humidity-regulating packs help keep the moisture stable.

Airtight containers are effective for containing the smell of cannabis and maintaining discretion. In addition, resealable bags or boxes can be used to control the odour during transport or storage.

Freezing cannabis in vacuum-sealed bags can be a suitable option for long-term storage. Before freezing, however, the cannabis should be dried thoroughly to prevent the build-up of moisture and mould formation.

It is advisable to check your cannabis regularly for changes in smell, appearance and consistency. If unusual changes are noticed, such as an unpleasant smell or signs of moisture, the storage conditions should be reviewed and adjusted if necessary.
