The right storage container can make all the difference in keeping your cannabis fresh over long periods – so how well do Mason Jars work? Are they airtight? 

If you’re wondering about this, then you’ve come to the right palace. In this article, we’re going to take you through everything you’ll need to know about Mason Jars.

We’ve also included some information about the dos and don’ts of storing cannabis. So let’s jump right into it! 

How Do You Make A Mason Jar Airtight?

Mason Jars have long been a popular choice for strong cannabis because they are made of glass, which prevents the degradation of cannabinoids and terpenes that can occur with other materials like plastic.

However, you should know that not all mason jars are airtight. With this in mind, you should know that there are a few things you can do to ensure your mason jar is airtight.

1. Choose The Right Jar

To begin, you’re going to need to make sure that you choose the right jar. The truth is that not all jars are created equal.

To ensure the one you’re looking at is airtight, you want to check if it has a two-piece lid, which includes a flat metal disc with a (generally plastic) screw-on band. This type of lid creates a seal that is more airtight than a one-piece lid.

2. Tighten Your Lid

Even if the jar you have purchased has the capability of becoming airtight, this won’t be effective if you haven’t made sure to tighten the seal. Make sure that your mason jar is adequately sealed and that there are no gaps where air can get into the space.

3. Fill Your Jar Correctly

You’re going to need to make sure you fill your jar correctly. If you have enough cannabis to fill up your jar, then you’re going to need to make sure you leave enough room for the lid to be fastened correctly.

Overfilling the jar can prevent the lid from creating an airtight seal.

How Do I Know If My Mason Jar Is Airtight? 

There are a few ways to test if a mason jar is airtight:

1. Listen For A Popping Sound

When you first close the lid, listen for a popping sound. This sound indicates that the lid has been sealed properly and is airtight. You’ll be able to notice this when you open your jar back up also, and it may take considerable force to pry it open. 

2. Check Your Seal

The two-piece lid has a rubber gasket that creates an airtight seal. To test if the seal is tight, press down on the center of the lid. If it does not pop back up, the seal is airtight. 

3. Test With Water

Another way to test the airtightness of the jar is to fill it with water, close the lid tightly, and turn it upside down. If no water leaks out, the jar is likely to be airtight.

Are Mason Jars Airtight Without Canning?

Let’s take a look at some of the history of mason jars. You should know that Mason jars were originally designed for canning, which involves sterilizing and processing food at high temperatures to preserve it.

While canning requires airtightness, not all mason jars are airtight without canning. As mentioned earlier, airtightness can be achieved by using the right type of lid, filling the jar correctly, and tightening the lid properly.

Mason jars are not vacuum-sealed like commercial food storage containers, so they are not 100% airtight. However, they provide a good level of airtightness for cannabis storage, especially if you follow the steps outlined above.

Are All Glass Jars Airtight?

Not all glass jars are airtight. Some jars have lids that do not create an airtight seal. When choosing a glass jar for cannabis storage, ensure that it has a two-piece lid with a rubber gasket.

This type of lid creates an airtight seal that prevents air and moisture from entering the jar and affecting the quality of the cannabis.

Final Thoughts 

Mason Jars have long been a popular choice for storing cannabis. They are made from glass and will provide you with a decent level of airtightness that will allow you to keep your bud fresh and potent.

However, you’ll need to make sure that your jar is airtight, and that you have adequately sealed it after each time you open it up.

Another thing we’d like to mention is that you’ll also want to make sure you store your cannabis away from direct sunlight and heat.

Excessive exposure to light or heat can cause the cannabinoids and terpenes in your bud to degrade, reducing both the potency and flavor of your cannabis.

We hope that this guide has told you everything you wanted to know about using a mason jar to store your cannabis and that you’re now more confident about airtight seals.

Frequently Asked Questions 

How Long Can You Store Cannabis In A Mason Jar?

With proper storage, cannabis can be stored in a mason jar for up to six months or longer. You should know that the quality of your cannabis may degrade over time, even in an airtight environment. 

Can You Reuse A Mason Jar For Cannabis Storage?

Yes, there’s no reason why you can’t reuse a mason jar for cannabis storage, as long as it is clean and airtight.

However, it’s important to note that cannabis can absorb flavors and aromas from the jar, so it’s best to use a dedicated jar for cannabis storage.

Can You Store Cannabis In Plastic Containers?

While plastic containers are not ideal for cannabis storage because they can allow air and moisture to enter, they can be used in a pinch.

If using a plastic container, choose one that is airtight and store it in a cool, dark place away from direct sunlight and heat.
