Quick Answer

Mason jars are ideal for cannabis storage because they create an airtight environment that protects against moisture, light, and air—three primary factors that degrade cannabis quality. Store your cannabis in a cool, dark place and ensure jars are filled to about 75-80% capacity to allow some air circulation without excess oxygen exposure.

Why Use Mason Jars?

Mason jars offer several benefits that make them suitable for cannabis storage:

• Airtight Seal: The rubber-lined lids of mason jars create an airtight seal, which helps keep moisture out and maintain the cannabis's natural humidity levels.
• Inert Material: Glass is non-reactive, meaning it won't alter the flavor or potency of your cannabis, unlike plastic containers.
• Visibility: The clear glass allows you to see your cannabis without opening the jar, reducing unnecessary exposure to air and light.
• Cost-Effective: Mason jars are generally inexpensive and widely available.

How to Store Cannabis in Mason Jars

Follow these steps to store your cannabis effectively using mason jars:

1. Clean Your Jars: Wash and dry your mason jars thoroughly to remove any dust or residues. Ensure they are completely dry before use to prevent mold growth.

2. Fill the Jars: Place your cannabis in the jar, filling it about 75-80% full. This allows for slight air circulation, which is essential for preserving freshness without exposing buds to too much oxygen.

3. Seal the Jar: Secure the lid tightly to create an airtight seal.

4. Store Properly: Keep jars in a cool, dark place, such as a cupboard or drawer, away from direct sunlight and heat sources.

Choosing the Right Mason Jar

When selecting a mason jar for cannabis storage, consider the following:

• Size: Choose a jar size that fits your cannabis quantity. Larger jars are suitable for bulk storage, while smaller jars are ideal for personal use.
• Color: While clear jars are common, consider using tinted jars to further protect against light exposure.
• Lid Quality: Ensure lids are in good condition with an intact rubber seal for maximum airtightness.

Tips for Optimal Cannabis Storage

• Avoid Plastic Bags: Plastic can affect flavor and potency. Always opt for glass jars.
• Monitor Humidity: Use humidity packs to maintain ideal cannabis humidity levels (55-62% RH).
• Limit Air Exposure: Open jars only when necessary to minimize air exposure.
