When it comes to storing cannabis effectively, the key goals are to maintain its potency, flavor, and overall quality while preventing any potential degradation. Cannabis, like any other botanical product, is affected by environmental conditions such as light, heat, humidity, and air quality. Here are some optimal methods to preserve your cannabis for an extended period.

**1. Airtight Containers:** Glass jars with airtight seals, such as mason jars, are ideal for storing cannabis. They can effectively prevent the entry of excess oxygen and humidity, which can degrade the product over time. Plastic bags or containers should be avoided as they can create static that can degrade trichomes (the tiny, crystal-like hairs on the plant that contain most of the plant's cannabinoids).

**2. Controlled Temperature:** Cannabis is best kept in cool places, as heat can cause cannabinoids and terpenes to degrade, affecting the taste and potency of the cannabis. However, storing your cannabis in a fridge or freezer is not recommended because the fluctuations in humidity and temperature can actually promote mold growth and cause trichomes to become brittle and break off.

**3. Limited Light Exposure:** UV rays can degrade cannabinoids, leading to a decline in potency. Always store your cannabis in a dark place to limit light exposure. Amber or dark-colored glass jars can also help to block harmful UV rays.

**4. Appropriate Humidity:** The ideal relative humidity (RH) for cannabis storage is between 59% and 63% RH to maintain and enhance color, consistency, aroma, and flavor. Storing cannabis in conditions with either too much or too little humidity can lead to problems like mold or brittle, dry buds.

**5. Separate Stashes:** Different strains should be stored separately. Mixing strains can lead to the muddling of distinct flavors and effects. 

**6. Avoid Storage with Electronics:** Storing cannabis near electronic devices that give off heat can dry out your stash and degrade its quality. 

Remember, properly stored cannabis can last for up to two years without significant loss of potency. By controlling exposure to light, temperature, humidity, and oxygen, you can enjoy high-quality cannabis for an extended period. 

However, storage practices can vary based on personal preferences and the specific characteristics of the cannabis strain, so it's also worth experimenting to find the best method for your needs.

Our Recommendation:

Something like this would be ideal - rather inexpensive (there is an option to buy a single one for around 20$) - an airtight container which already includes a humidity pack:
