Store cannabis properly and keep it fresh for a long time

Proper storage of weed is crucial to preserving its quality, flavor and potency over time [1]. Proper storage can make the difference between a fresh, aromatic product and one that has lost its best properties. Proper storage ensures not only that the cannabis retains its potency, but also that it can preserve its unique aromas and flavor profiles.

Cannabis storage basics

Storing cannabis requires careful consideration of various factors to preserve its quality and potency over the long term [1]. It is crucial that cannabis be stored in a dark place, protected from light, air, moisture and extreme temperature changes. UV light is known to break down cannabinoids and can therefore reduce the potency of cannabis [1]. Oxygen accelerates the oxidation process, which helps break down terpenes and can affect aroma and taste [1]. An imbalance in moisture can also have serious consequences: too much moisture promotes the growth of mold and bacteria, while too little moisture causes the flowers to dry out and lose flavor [1]. Furthermore, extreme temperatures can negatively affect the quality of cannabis by changing the chemical properties of the flowers [1]. Therefore, it is of utmost importance to create the right environment for storing weed to best preserve its quality and potency.

New regulations in Germany from April 2024:

From April 1, 2024, a new legal framework for dealing with cannabis will apply in Germany. This change will legalize the possession of up to 25 grams of cannabis for personal use and the cultivation of up to three cannabis plants. In addition, communal cultivation in so-called cannabis clubs will be possible under strict conditions. For further information, please visit the official website of the German Bundestag .

The ideal storage of cannabis

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

Humidity control

Another important aspect of cannabis storage is controlling humidity. A constant relative humidity of 59-63% is crucial to support the quality of the cannabis, thereby counteracting the risk of mold growth [1]. Moisture regulating packs are a solution to maintaining these optimal conditions in the storage containers. These packs help to stabilize the humidity and keep the cannabis fresh so you can enjoy it at any time.

Avoiding the spread of odors

Cannabis can give off a strong smell, which you may want to minimize. Using airtight containers is an effective method to not only counteract the loss of terpenes but also safely seal in the smell [1]. These containers provide a reliable barrier against the spread of odor, ensuring discretion and privacy. For additional odor control, you can store the airtight containers in sealable bags or boxes to ensure the odor remains under control during transport or storage [1]. These measures can help you prevent the intense smell of cannabis from entering your surroundings and maintain discretion.

Practical tip for at home: “Burping”

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

Long term storage

If you want to store cannabis 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 prevent the formation of moisture and the associated mold 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 sealing can prevent air from entering, which can result in a longer shelf life [3].

Regular controll

Regardless of the storage method you choose, it's important to regularly check your cannabis for mold and moisture. By regularly checking your cannabis for changes in smell, appearance, and consistency, you can identify potential problems early. If you notice any unusual changes, such as an unpleasant odor, discoloration or signs of moisture, it is advisable to check the storage conditions and adjust them if necessary. You may need to change storage locations or control humidity.

Following these guidelines can help cannabis consumers and patients keep their cannabis fresh. By regularly monitoring your cannabis and adjusting storage conditions accordingly, you can ensure that you always enjoy a shelf-stable product.

Frequently asked questions about cannabis

Proper storage of cannabis is crucial to preserving its quality, flavor and potency over time. Proper storage protects cannabis from harmful light, air, moisture and temperature fluctuations that 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 cannabis from light and air, while humidity control packs help keep humidity stable.

Airtight containers are effective at sealing in the smell of cannabis and maintaining discretion. Additionally, sealable bags or boxes can be used to control odor during transportation or storage.

Freezing cannabis in vacuum-sealed bags can be a suitable option for long-term storage. However, before freezing, the cannabis should be dried thoroughly to prevent moisture and mold from forming.

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