You know the problem: you buy high-quality cannabis, and after a few weeks it's dry, scratchy, and has hardly any taste left. The question of how to store cannabis properly in order to maintain its quality and potency for as long as possible comes up time and time again. We'll show you how to store your cannabis flowers properly—when it comes to herb storage, it's all about how to store cannabis correctly to preserve its potency, aroma, and freshness.
The problem that everyone knows
You've finally got your hands on some really good weed. The buds smell fantastic, feel perfect, and the effect is just right. But then it happens— after two weeks in the plastic bag, your weed is dry as dust and tastes like... well, nothing.
Sound familiar? Us too. That's why we've taken a close look at the topic of herb storage . Because let's be honest: good cannabis isn't cheap. So it's a shame when the quality suffers due to improper storage.
Incorrect storage costs you money and enjoyment. Improper storage leads to a loss of potency, aroma, and quality, as light, oxygen, and moisture can break down the active ingredients.
The good news? With the right methods, you can keep your cannabis buds fresh for months. And it's not as complicated as you might think.
Why proper storage is so important
Before we get to the practical tips, let's briefly clarify why storing cannabis is so important. Cannabis is considered both a luxury food and a natural product and is highly sensitive to external influences such as light, temperature, and humidity , which significantly affect its quality and shelf life.
Cannabis is a natural product. Like any plant, it is subject to natural degradation processes. The valuable cannabinoids and terpenes, which are responsible for its effects and taste, are sensitive to various environmental factors. Cannabinoids such as THC and cannabinol play a crucial role in determining the active ingredient content and desired effect – their stability depends heavily on proper storage.
What happens if stored incorrectly?
- THC breaks down and turns into CBN (makes you tired instead of high)
- Terpenes evaporate (flavor and aroma are lost)
- Moisture escapes (cannabis becomes dry and scratchy)
- Mold can develop (if humidity is too high)
- Effectiveness decreases (less effect with the same amount)
- Light, temperature, and humidity accelerate the aging process, affect cannabinoids (especially THC and cannabinol/CBN), and promote mold growth, which compromises the quality and safety of cannabis products.
Proper storage of cannabis is therefore essential to preserve the active ingredient content and maintain the freshness and potency of marijuana and other cannabis products. Research shows that the conversion of THC to cannabinol is a natural process that can be accelerated by external influences – however, further studies on cannabinoids and their stability are necessary. Similar to other natural products such as vegetables or medicines, cannabis flowers also require special storage conditions to maintain their quality. The surface of the flowers plays an important role here, as a larger contact area increases the degradation of active ingredients and sensitivity to environmental influences. Controlling humidity is crucial for the health of the plants and to prevent mold growth.
The enemies of your cannabis
To store cannabis properly, you need to know its "enemies." Environmental factors such as humidity, temperature, and light play a crucial role in the freshness and shelf life of cannabis. These are the factors that damage quality:
1. Light (especially UV radiation)
Light is the biggest enemy of your cannabis buds. UV radiation breaks down cannabinoids and causes terpenes to evaporate. That's why you should never store your weed in transparent containers by the window.
UV light also accelerates the aging process of cannabis, causing the quality of the flowers to deteriorate more quickly.
2. Air and oxygen
Too much oxygen causes the active ingredients to oxidize. This is the same process that causes a bitten apple to turn brown. In the case of cannabis, this means that its potency decreases.
3. Extreme temperatures
Heat accelerates the breakdown of cannabinoids. Cold can make the trichomes (the small resin glands) brittle. The ideal temperature is between 15 and 21°C.
4. Incorrect humidity
Too dry (below 55% humidity): Cannabis becomes brittle and loses terpenes. Too humid (above 65% humidity): Risk of mold! Controlling humidity is crucial to maintaining plant health and preventing mold growth. Due to cannabis' sensitivity to external influences such as humidity, improper storage can significantly affect the quality and safety of the flowers.
5. Contamination
Dirt, bacteria, or other contaminants can impair quality and be harmful to health.
The perfect storage conditions
Now that you know who the enemies are, we can define the optimal conditions:
Temperature: 15-21°C (room temperature is acceptable)
Humidity: 55-65% (60-62% is ideal)
Light: Complete darkness
Air circulation: Minimal (airtight container)
Cleanliness: Sterile, clean containers
To store cannabis properly and maintain its freshness and quality over the long term, you should consider various storage methods. There are numerous options, such as special vacuum containers or airtight containers in differentdesigns and sizes, which are optimally tailored to your needs. Cabinets are particularly suitable as storage locations, as they protect the cannabis from light. The refrigerator, on the other hand, is usually not a good option, as temperature fluctuations and humidity can affect the quality of the flowers.
Sounds complicated? It's not. With the right tools, it's very easy to implement.
The best containers for storing cannabis
Glass – The Gold Standard
Glass is the best material for storing cannabis. Why?
- Airtight seal
- No odor transfer
- Easy to clean
- Chemically inert (does not react with cannabis)
- Reusable
Glass jars, especially preserving jars, are ideal for storing cannabis safely and airtight. They preserve freshness, taste, and aromas optimally, protect against light, and are easy to handle.
Important: The glass should be dark or tinted to block UV light. Brown or green apothecary jars are perfect.
Our tip: The Norddampf with Miron glass and hygrometer is specially designed for storing cannabis. The Miron glass protects against UV light, and the integrated hygrometer shows you the humidity level.
Special cannabis containers
concentrates” class=”wp-image-87888″/>There are now many containers that have been specially designed for storing herbs. Vacuum containers are a particularly effective option for long-term storage, as they optimally preserve the freshness and potency of the herb. These containers are available in different designs and sizes, so there is a suitable model for every need. They often offer practical features such as:

Similar to vegetables and medicines, cannabis requires special storage conditions to maintain its freshness and effectiveness. The refrigerator is therefore usually not the best choice.
- Freezer: Makes the trichomes brittle
- Metal containers: Can rust and transfer taste
Step by step: How to store cannabis correctly
1. Preparation
- Washing hands: Cleanliness is important
- Clean containers: Disinfect with alcohol and allow to dry.
- Prepare your workspace: Clean surface
2. Check cannabis
- Test moisture: The flowers should bend easily without breaking.
- Check for mold: White, gray, or black spots are a no-go.
- Assessing quality: Only store flawless material with the highest possible content of active ingredients such as THC or CBD.
3. Portion correctly
- Small quantities: It is preferable to have several small containers rather than one large one.
- Not too full: leave some space for air circulation
- Separate varieties: Store different varieties separately
4. Regulate humidity
- Use a hygrometer: To monitor humidity. Humidity plays a crucial role, as it significantly affects the quality and shelf life of cannabis. An optimal balance prevents mold growth and preserves the active ingredients.
- Boveda Packs: Automatically regulate humidity.
- Adjust as needed: Too dry? Add a moisture pack. Too moist? Let it dry.
5. Seal properly
- Airtight: The container must be completely sealed.
- Not too tight: Do not crush the flowers
- Labeling: Note the variety and date
6. Choose the optimal storage location
- Dark: Cupboard or drawer – Cupboards are a particularly good option as they protect cannabis from light and UV rays. There are various storage options, such as cupboards, drawers, or special containers, which can be chosen depending on space and requirements.
- Cool: Not next to the heater
- Dry: Not in the bathroom
- Safe: Protected from children and pets
Common mistakes in cannabis storage
Mistake 1: Storing in the refrigerator
Many people think that cold is better. But the refrigerator is too humid and too cold. The trichomes become brittle and can break off. Storing cannabis inside a refrigerator is problematic because frequent fluctuations in temperature and humidity can negatively affect the quality of the cannabis flowers.
Exception: For very long-term storage (over 6 months), refrigeration may be advisable—but only in airtight containers.
Mistake 2: Containers that are too large
A large container with little cannabis means a lot of air. And air is bad for shelf life. Better: use smaller containers. There are various options and types of containers that are suitable depending on the quantity required and the desired storage period.
Mistake 3: Constantly opening
Every time you open the container, you replace the air. This accelerates decomposition. Only open it when you really need something.
Mistake 4: Ignoring incorrect humidity levels
Without a hygrometer, you don't know if the humidity is right. It's like driving a car without a speedometer.
Humidity plays a crucial role in the quality and shelf life of cannabis, as it, together with temperature, has a significant influence on the preservation of the active ingredients.
Mistake 5: Mixing different varieties
Each strain has its own terpene profile. When you mix them, the aromas transfer and you lose the characteristic properties.
Long-term storage: If you have larger quantities
Sometimes you may have larger quantities of cannabis that you want to store for months. There are various options and storage methods for long-term storage, such as special containers and different variants that preserve the freshness and quality of your cannabis. Here are our tips:
vacuum packaging
For very long-term storage, you can vacuum pack cannabis. This method is considered an effective option for preserving the freshness and potency of the weed over a longer period of time, as it removes almost all oxygen.
Caution: Do not vacuum too strongly, otherwise you will crush the flowers.
portioning
Divide large quantities into smaller portions. That way , you don't have to expose the entire supply to the air.
Double packaging
First divide into small containers, then store in a larger container. This creates an additional protective layer.
There are various options and types of containers available for double packaging, such as vacuum containers in different sizes and designs, which enable safe and fresh storage.
storage location
A cool, dark cellar is ideal for long-term storage . The temperature should be constant. Alternatively, cupboards are also an option, as they protect the cannabis from light. There are various storage options, such as special vacuum containers or light-proof boxes, each of which offers different advantages for storage.
Medical cannabis: Special considerations
Similar to medications, proper storage of cannabis is crucial to maintaining its potency and quality. If you use cannabis for medical reasons, proper storage is even more important: medical cannabis and other cannabis products must be stored with particular care, as factors such as light, humidity, and temperature can affect their shelf life and potency. The Hemp Association recommends storing cannabis products in a cool, dry place away from light to best preserve their freshness and quality.
Consistent effect
With medical cannabis, it is important that each dose has the same effect. Incorrect storage can alter the concentration of active ingredients.
hygiene
Medical cannabis must be stored in a particularly clean manner. Use sterile containers and always wash your hands.
documentation
Keep a storage log: when purchased, how stored, how long it will keep. This will help you determine the optimal storage time.
Signs of poor storage
How can you tell that your cannabis is no longer at its best?
Visual signs
- Discoloration: Brown or yellowish spots
- Mold: White, gray, or black spots
- Trichomes fall off: Lots of "dust" in the container
- Too dry: flowers crumble when touched
smell
- Musty smell: Indicates mold
- No aroma: Terpenes have evaporated
- Hay smell: a sign of poor drying or storage
texture
- Too dry: crumbles into dust
- Too moist: Feels spongy
- Sticky: May indicate mold
effect
- Weaker effect: THC has broken down. The breakdown of THC into cannabinol (CBN) is a natural process that changes the effect of cannabis. Various cannabinoids, and in particular the THC content, have a significant influence on the effect.
- Tired instead of high: THC has turned into CBN.
- Sore throat when smoking: Too dry
Troubleshooting: When things go wrong
Problem: Cannabis has become too dry
Solution:
- Add Boveda pack with 62% humidity
- Or: A small piece of apple peel for 2-3 hours (no longer!)
- Be patient—rehydration takes a few days.
Problem: Cannabis is too moist
Solution:
- Open the container and let it air out for a few hours.
- Add rice grains in a tea bag (they absorb moisture).
- In case of high humidity: Dry completely again
Problem: Suspected mold
Solution:
- Dispose of immediately! Mold is harmful to health. Due to cannabis' high sensitivity to external influences such as humidity and temperature, improper storage can quickly lead to mold growth. It is therefore particularly important to monitor storage conditions.
- Thoroughly disinfect containers
- Check other supplies
Problem: Aroma has been lost
Solution:
- Unfortunately, it cannot be undone.
- For the future: Better storage
- Can still be used for edibles
The science behind it: What really happens?
For those of you who are curious: What actually happens chemically during storage?
decarboxylation
When exposed to heat and time, THCA (non-psychoactive) converts to THC (psychoactive). Decarboxylation is a process that activates cannabinoids such as THCs. This is actually beneficial—but only up to a point. Research into the effects of decarboxylation on various cannabinoids, including cannabinol, is still ongoing.
oxidation
THC oxidizes to CBN. During this process, the cannabinoid THC is converted to cannabinol (CBN) through oxidation, which alters the effect and effect profile of the cannabinoid. CBN makes you tired instead of high. This is why old cannabis often has a sedative effect.
terpene loss
Terpenes are volatile compounds. They evaporate slowly at room temperature. This is why poorly stored cannabis loses its aroma.
Degradation by UV light
UV radiation breaks down the molecular chains of cannabinoids. UV light has a strong influence on the aging process of cannabis, as external influences such as light can significantly impair its quality and shelf life. This is irreversible—once broken down, the effect is gone.
