Ideal Temperature and Humidity for Cannabis Storage

To preserve the quality and potency of your cannabis, store it in a cool, dark environment with temperatures between 60-68 degrees Fahrenheit (15-20 degrees Celsius)[1].

Humidity levels should be maintained around 50-62 percent[2] to prevent mold growth and maintain the ideal moisture content for your cannabis.

Storage Containers

Optimal Storage Containers for Cannabis

Airtight glass jars are the best choice for storing cannabis flowers. The jars should be filled as tightly as possible to minimize exposure to oxygen, which can degrade the cannabis over time[4].

Pre-rolls can be stored in their original containers or in airtight glass jars to maintain freshness[4].

Why Choose Glass Over Plastic?

Glass containers are preferred over plastic because they are less permeable, preventing unwanted odors from escaping and ensuring that the cannabis remains potent and flavorful.

Additionally, glass does not hold a static charge, which can cause trichomes to stick to the container, leading to a loss of potency.

Protecting Your Cannabis from Light and Air

To further preserve your cannabis, store it in a dark location away from direct sunlight. UV rays can degrade the cannabinoids and terpenes in your cannabis, leading to reduced potency and altered flavors[7].

Keeping your cannabis in an airtight container also minimizes exposure to oxygen, which can cause further degradation[2].

Using Humidity Packs for Optimal Moisture Control

To maintain humidity levels in your cannabis storage container, consider using humidity packs. These packs regulate the moisture levels within the container, ensuring your cannabis remains fresh and potent for an extended period[5].

Common Cannabis Storage Mistakes to Avoid

  1. Storing cannabis in the refrigerator: While some might consider a refrigerator a cool, dark location, others advise against this due to the increased moisture content, which can lead to mold growth[7].

  2. Using plastic bags or containers: Plastic is permeable and can allow odors to escape, compromising the cannabis's flavor and aroma. Additionally, plastic can create a static charge, causing trichomes to stick to the container, resulting in a loss of potency.

  3. Storing cannabis with other aromatic substances: Avoid storing your cannabis near strong-smelling foods or products, as the cannabis can absorb these odors, altering its flavor.

By following these guidelines for proper cannabis storage, you can ensure your stash remains fresh, flavorful, and potent for an extended period.

With the right temperature, humidity levels, and proper storage containers, your cannabis will remain fresh and potent for an extended period.

Additionally, using humidity packs and storing your cannabis in a dark location away from direct sunlight will further ensure that your stash retains its flavor, aroma, and potency[1,2,4,5,7].

The Importance of Proper Cannabis Storage in Various Climates

In regions with fluctuating temperatures and humidity levels, maintaining proper cannabis storage conditions becomes even more crucial. As air temperature increases, relative humidity (RH) decreases, and vice versa[2].

High humidity levels, especially around 70% or higher, can create ideal breeding conditions for mold, which can negatively impact your cannabis and pose health risks[5].

Adapting Your Cannabis Storage for Cold Climates

In cold climates, indoor heating systems can cause a significant decrease in RH, leading to dry air[2].

To counteract this effect, consider using a humidifier to maintain proper humidity levels in your storage area, or place humidity packs inside your airtight glass jars to regulate moisture content.

Adapting Your Cannabis Storage for Warm Climates

In warmer climates, it's essential to keep your cannabis in a cool, dark location and monitor humidity levels closely.

Using air conditioning or a dehumidifier can help maintain ideal storage conditions and prevent mold growth[6]. Ensure that your storage area is well-ventilated and regularly inspect your cannabis for any signs of mold or degradation.

Storing Various Forms of Cannabis

While our previous discussion focused primarily on cannabis flower, it's essential to address the storage needs of other cannabis products such as edibles, concentrates, and tinctures.

Adapting your storage practices based on the specific type of cannabis product will help preserve its potency and effectiveness.


Edibles for Stash box



Cannabis-infused edibles should be stored in a cool, dark place, similar to how you store cannabis flower.

However, it's crucial to follow any additional storage instructions listed on the product packaging, as edibles may have unique requirements due to their ingredients. For instance, some edibles may need to be refrigerated to maintain freshness.


Cannabis concentrates, such as wax, shatter, or oil, should also be stored in a cool, dark location. Use airtight, non-stick containers to store concentrates and keep them away from direct sunlight.

Silicone containers are ideal for storing sticky concentrates, as they prevent the product from adhering to the container's walls.


Cannabis tinctures should be stored in a cool, dark place away from direct sunlight, preferably in a cupboard or a cabinet.

Most tinctures come in dark-colored glass bottles to protect their contents from light exposure. Make sure the bottle's cap is tightly sealed to avoid evaporation or contamination.

In conclusion, storing different forms of cannabis products properly is essential to preserving their potency, flavor, and overall quality.

By following these storage recommendations, you can ensure that your cannabis remains fresh and effective for an extended period.
