What is a cannabis glass jar?  


As you know, the lesser your cannabis oils, hemp lotion, and dry marijuana leaves come in touch with air, moisture, and the surroundings, the more effective they are. 


A cannabis glass jar is a glass jar that does not react with cannabis and can be used to protect it. Inert materials don't react with their contents, which makes glass an inert material.


Cannabis oils retain their efficacy longer when stored in colored glass jars since glass does not absorb oil like other materials. When adequately sealed, glass jars can keep dry leaf cannabis potent for a long time. To avoid unwanted chemicals seeping into their marijuana, people prefer to store their cannabis in glass containers rather than plastic. 



Types of Glass Jars for Cannabis


At MJ Wholesale, you can choose from various forms and sizes of glass jars. Jars come in various sizes, ranging from 1 oz. to 4oz and even up to  21 oz. Jars. The jar's mouth (opening) may also vary in size. Some have wide mouths for simple filling, while others have a slender neck for precise pouring.

Here are some of the most popular types of glass jars for cannabis:

  1. Mason Jars

Mason jars are the most popular for storing weed and come in various shapes and sizes. Mason jars are made of glass and are airtight, making them ideal for storing cannabis.  

They're named after John Landis Mason, who invented them in 1858. They were used initially for canning food, but nowadays, they're used for everything from candles to cannabis.

  1.  Ball Jars 

Ball jars are similar to mason jars but have a different lid type that creates an airtight seal. Ball jars are also made of glass and are perfect for storing cannabis.


3. Honey Jars


Honey jars are smaller and broader than mason jars. They have a flat bottom and a big mouth that makes filling them simple.

4.Potion Bottles

Potion bottles are tiny glass bottles with a cork stopper. They're perfect for storing small amounts of cannabis oil or tincture.


Vials are small glass jars with a screw-on cap. They're often used for storing cannabis concentrates like wax and shatter.


How does a Cannabis Glass Jar work?


Cannabis is cured or stored in glass jars at dispensaries, plantations, and stores. Glass jars have many benefits when it comes to storing cannabis. 

Let us look at a few. 


1.Glass Jars Preserve Potency of Cannabis

When cannabis is exposed to air, it begins to degrade. This process is accelerated when cannabis is exposed to light or heat. Oxygen is prevented from coming in contact with marijuana with the help of an airtight seal formed by glass jars. This ensures the cannabis stays potent for a long time. 


2.Glass Jars are smell proof

Another problem with storing weed in plastic bags is that plastic can absorb the smell of the weed. This is why your weed always smells stronger when opening a new bag. Glass jars prevent this from happening because they're non-porous. This means the smell of your weed will be contained within the jar and won't leak out.


3.Glass Jars Are Easy to Clean

Glass is a relatively simple material to clean. You can wash it with soap and water, or you can even put it in the dishwasher. This is important because it ensures your weed is stored in a clean environment. Glass jars are also easy to sterilize if you're worried about germs or bacteria.


4.Glass Jars Don't React with Cannabis

Glass is immune to interaction with its contents due to its inert nature. To avoid unwanted chemicals seeping into their marijuana, many people prefer to store it in glass rather than plastic.


5.Glass Jars are Discreet

Glass jars are usually clear, which makes them less discreet than opaque containers. However, you can find glass jars with opaque lids that will keep your weed hidden from a top view. You can also find glass jars in various colors and choose the one that best matches your style.


6.Glass Jars are available in many sizes

Glass jars come in many sizes. Whether you need a small jar for a vape pen or a large jar for your flower, you'll be able to find it easily. 


7.Black glass jars block out UV rays

Black jars do not allow for easy product viewing and may be used to store cannabis discretely. Keeping cannabis away from dangerous UV radiation is essential, and black jars provide this benefit.


How to use a Cannabis Glass Jar


In this part, we will see how to store cannabis in a glass jar as well as how to cure cannabis in a glass jar. 


1.How to store cannabis in a glass jar


If you're storing flower, you'll want to use a big enough jar to hold all of your buds. Jars with a wide mouth are ideal, as they make filling easy and provide quick access to the weed. If you're storing cannabis concentrates like wax or shatter, you'll want to use a smaller jar.

To store your cannabis in a glass jar, first, ensure the jar is clean and dry. Then, add a layer of parchment paper to the bottom of the jar. This will help keep your weed from sticking to the glass. Next, add your weed to the jar slowly. Ensure that there is as little air space as possible in the pack. Finally, put the lid on the jar and seal it tight. You can store your cannabis jar in a cool, dark place like a cabinet or drawer. 


2.How to cure cannabis in a glass jar


During the curing process, cannabis is dried and stored under controlled conditions. This helps improve the weed's taste, smell, and potency. Curing cannabis in a glass jar is a great way to do this because it prevents oxygen from degrading the weed. It also keeps the weed smelling fresh and prevents it from interacting with other materials.


Here is a quick guide to curing cannabis. 


1. Start with fresh, dry cannabis. Make sure to trim away any large fan leaves.

2. Spread the Cannabis on a baking sheet and bake it at 245 degrees Fahrenheit for 30-60 minutes. This will help activate the THC and CBD in your weed.

3. Let the cannabis cool, then grind it into small pieces.

4. Place the ground cannabis in a clean glass jar. Fill it with about ¾ of the jar.

5. Make sure the jar is tightly sealed and store it in a cool, dark place for 2-3 weeks. During the period, open the jar once daily to allow air to circulate and prevent mold from forming.

6. After 2-3 weeks, your cannabis should be cured and ready to smoke!

How to Clean a Cannabis Glass Jar

Cleaning your glass jars regularly will prevent build-up and bacteria from forming. This will keep your weed fresh and potent. There are many ways to clean a cannabis glass jar. You can use any of the below-mentioned methods for the same.


1.Using hot water and soap


Use hot water and soap to clean a glass jar effectively. Rinse the jar with hot water, then add a drop of dish soap. Use a sponge or brush to scrub away any residue. Rinse the jar out again, then dry it with a clean towel. 


2.Using Isopropyl Alcohol (ISO)


Use 70% ISO and 30% water for a dilution ratio of 70/30. Fill the jar halfway with the mixture and drain it. Fill the jar halfway with clean hot water and let it soak overnight. Dry it with a towel. 


3.Using Hot Water and Rock Salt


Fill the jar with hot water and rock salt, then let it soak for 24 hours. Drain the mixture and rinse the jar out with hot water.


Glass Jars vs. Plastic Baggies: Cannabis Packaging


Let us compare glass packaging and plastic packaging when it comes to cannabis.



Glass is 100% recyclable. It can be reused and recycled endlessly. It is very tough to recycle plastic and cannot be reused too often.


2.Chemical Leeching

Glass containers are known not to leech any chemicals or odors. However, according to research, plastic can leech chemicals like bisphenol A (BPA) that cause cancer.



Glass jars block oxygen from reaching the cannabis, thus preventing its dehydration and retaining its potency. Plastic, on the other hand, is porous and can dry out the weed, leading to substandard weed.


4.Child Resistance

Glass lids can be designed to be childproof. Plastic baggies are not childproof. 


5.Food Safety

Most glass containers are food safe. Plastic can burn trichomes, the potent part of the weed. 

Should I stock glass jars in my head shop?

As every head shop owner knows, customers can be pretty particular about their smoking supplies. Some people like their pipes made of glass, while others prefer metal or wood. 


However, all smokers can agree on the importance of having a good supply of glass jars on hand. Glass jars are perfect for storing tobacco, herbs, and concentrates. They keep the contents fresh and dry and are easy to clean and use repeatedly. Plus, they look fantastic on the shelf of any head shop. So, if you're looking to stock your shelves with must-have smoking supplies, add some glass jars to the mix. Good quality glass jars can make all the difference for storing marijuana if you own a dispensary. 


The cannabis business is a highly competitive one. As several states in the United States now allow medical and recreational cannabis usage, the competition is expected to get increasingly fierce.
