The Secret to Perfect Cannabis Storage: Humidity Packs
Posted by Tom's Tumbler on May 21st 2024
As the popularity of cannabis continues to grow, so does the need for effective storage solutions. One solution in the cannabis world is the use of humidity packs. These small, often overlooked packs play a crucial role in preserving the freshness and potency of your cannabis flowers.
In this guide, we’ll explore why humidity control matters, how humidity packs work, and how they can help your operation maintain consistent quality from cure to consumer.
Why Proper Humidity Control Is Essential in Cannabis Cultivation
Maintaining the right humidity level is essential for preserving the quality of cannabis. If the humidity is too high, it can promote the growth of mold and mildew. On the other hand, overly dry conditions can cause the buds to become brittle and lose potency.
The ideal storage range for cannabis is 55%–62% RH, depending on your strain and packaging method. Maintaining this balance keeps flower flavorful, aromatic, and potent.
What Are Humidity Packs and How Do They Work?
Humidity packs (also called humidity control packs or moisture packs) are self-contained, two-way humidity regulators. They contain a precise blend of salts and water that either release or absorb moisture to maintain a specific humidity level.
Think of them as a built-in climate control system for your cannabis storage, keeping your flower in the sweet spot of that ideal humidity range no matter what’s happening outside.

Benefits of Using Humidity Packs
1. Preserve Potency
Maintaining optimal humidity levels helps to preserve the potency of the cannabinoids and terpenes in cannabis flowers, ensuring that they retain their therapeutic properties and flavor profiles for longer periods.
2. Prevent Mold and Mildew
By controlling humidity in your cannabis cultivation, humidity packs help prevent mold and mildew growth. Better humidity control for your cannabis storage prevents contamination and potential health risks.
3. Enhance Aroma and Flavor
Proper humidity preserves terpenes, the compounds that give each strain its unique scent and taste. That means smoother hits and better flavor retention over time.
4. Extend Shelf Life
Cannabis stored with humidity packs tends to have a longer shelf life than improperly stored flowers, which can degrade more rapidly over time.
How to Use Humidity Packs for Effective Cannabis Storage
Using humidity packs is simple, but a few best practices can make all the difference:
- Choose the Right Humidity Level:
- 58% RH: Ideal for smoother smoke and slightly drier flower.
- 62% RH: Best for preserving terpenes and freshness.
- 65% RH: Suitable for long-term storage or very dry climates.
- Place in an Airtight Container: Add your humidity pack to sealed containers like mason jars, metalized heat-sealable bags, or vacuum-sealed pouches. Metalized packaging is now preferred for its superior light and air protection.
- Monitor and Replace as Needed: Check packs regularly. When they feel hard or crunchy, it’s time to replace them.
- Store in the Right Environment: Keep containers in a cool, dark place away from direct sunlight or heat sources. Light and heat can degrade cannabinoids quickly.
Pro Tips for Effective Cannabis Storage
- Don’t overload containers. Leave a little space for airflow to allow the pack to regulate humidity effectively.
- Use one pack per jar or bag. Each humidity pack is designed for a specific volume, so using the right size ensures consistent control.
- Integrate humidity control post-trim. Adding packs immediately after trimming and curing helps preserve optimal moisture from the start.
- Pair humidity packs with proper packaging. The combination of humidity control and air-tight packaging can extend shelf life.
