The Best Weed Containers to Keep Your Marijuana Fresh

Have you ever found that cannabis can turn from its healthy forest green color to a dull brown? If so, you’ll probably realize that it is due to light and oxygen exposure. What’s happened is that much of the THC in the marijuana is now CBN.

You can still use the bud, as long as it isn’t moldy, but the high is different. The cannabis is now less intoxicating and provides a sedative effect that might spike your appetite. While CBN has some potential benefits, such as reducing the impact of pain, most users purchase marijuana to experience the effects of THC.

As a result, it is essential to learn how to store your buds. This guide looks at the five best weed containers on the market. First, however, let’s briefly investigate the right storage settings and why a container can help.

Why Do I Need a Cannabis Container?

If you spend hundreds, if not thousands of dollars on marijuana each year, it makes no sense to skimp on a container. After all, you can pick a good one for under $30. Properly stored marijuana can last for approximately a year. It still loses its potency and aroma over time, but the process is much slower.

If you spend hundreds, if not thousands of dollars on marijuana each year, it makes no sense to skimp on a container.

After a year, properly stored cannabis will lose approximately 16% of its THC. After four years, it will have lost over 40%. If left in the open, this process speeds up rapidly. Here are the ideal conditions for storing marijuana. Bear these in mind when purchasing a weed container:

  • A temperature of between 50- and 68-degrees Fahrenheit.
  • A relative humidity level of between 51% and 64%.
  • Kept away from direct light and heat.
  • An airtight space where oxygen can’t degrade the plant matter.

Ultimately, UV rays, oxygen, temperature, and humidity are the factors that impact cannabis the most.

What to Look for in a Weed Container?

There are hundreds of ‘stash jar’ options. You might find containers made from clay, wood, glass, and metal materials. However, you can quickly narrow the field by focusing on the following features:

Airtight Seal: If the container isn’t completely airtight, don’t waste your money. Any jar that allows the elements in will damage your weed. High-quality brands have a silicone or rubber gasket to guarantee that your cannabis isn’t exposed to air.

The Right Size: It is a mistake to purchase the largest container you can find. Using a big jar to hold a small amount of marijuana leaves too much air in the container.

Light Protection: Ideally, you’ll place your container in a cupboard away from direct light. However, if you’re the type of person that leaves your jar out, make sure it is made from UV-resistant material.

Keeps Aroma Inside: Don’t assume that every storage container is odor-proof! The last thing you need is the smell of cannabis wafting through the house and outside.

In general, a glass mason jar is a perfectly fine place to store your marijuana. It has a neutral electric charge, which is essential. However, unless you keep it in a cupboard away from light, your cannabis is still at risk. Consider an opaque jar if your marijuana is likely to be exposed to light.

One final note, don’t store your cannabis in a Ziploc bag for any length of time. This process reduces the potency and kills the aroma. Now, let’s look at five outstanding weed containers that keep your stash fresh.

1. Infinity Jars UV Glass Wide Mouth Screw Top Jar (100ml, 250ml, 500ml & 1000ml)

This is THE classic cannabis container brand. It comes from one of the oldest companies on this list. Infinity Jars was creating UV-resistant storage jars long before cannabis became legalized. You can purchase them in various sizes, and they all come with an easy-to-use wide-mouth screw top.


These containers are airtight, lightproof, smell-proof, and leak-proof. The glass is designed in Europe and is eco-friendly. While Infinity Jars are not designed specifically for cannabis storage, they tick every conceivable box. You can purchase a 10-pack to store other items apart from weed, but make sure to label them appropriately!

2. Canlock Stash (150ml)

Canlock is designed to keep your marijuana fresh. The brand also emphasizes that you can store tea, coffee, dried food, and other items, but it is ideal for storing weed. It is made from borosilicate glass to ensure your bud retains its aroma and taste. The black lid has a cool vacuum pump feature, which helps keep the odor from escaping.


The lid’s built-in airlock pump twists on and off the jar. When pumped, a pressurized seal is created to keep the smell of weed inside. Each container comes with a Boveda 62% humidifier. The Stash has a discreet design too. Perhaps the one downside is the relatively low storage capacity of 7 grams. If you need more storage, the Stash + can hold up to 14 grams.

3. Herb Guard Locking Stash Jar (250, 500ml & 1000ml)

This brand offers several outstanding options for storing your cannabis. However, we feel that its range of locking stash jars stands out. They come in three sizes and include an airtight and smell-proof protective locking pouch that protects the jar.


These jars are made of tinted, durable UV glass that keeps your bud fresh for longer. The airtight sealing lid works well, and it can keep your cannabis fresh for around six months. The sleek yet innocuous design means that no one will suspect you store weed in one of these jars.

As a bonus, each jar comes with a 62% 2-Way Humidity Control packet, along with a travel bag and labels for the contents.

4. FreshStor’s CVault (14+ grams)

The CVault is certainly a unique concept in the marijuana storage market. These containers resemble cooking pans with their food grade 304 stainless steel construction. They are ideal for short-term and long-term storage. Each CVault comes with a 62% humidity packet, and the design includes an airtight lid with metal clasps to keep it in place.


According to users, the airtight seal formed by the clasps helps keep their cannabis as fresh as the day they bought it. However, you must ensure that the clasps are tightly locked when you’re finished using the CVault. You can purchase one in various sizes, ranging from a maximum capacity of 14 grams to 1,000 grams!

5. Re:stash Jars (115+ grams)

This is an updated version of the traditional glass mason jar. This brand’s Stash Jars are BPA-free and made from eco-friendly materials. They are smell-proof, and CPSC certified child-resistant. The neutrally charged glass is an essential component in keeping your cannabis fresh, as is the child-proof polypropylene lid. If you’re environmentally conscious, you’ll like the fact that the lid is 30% repurposed from waste and hemp fibers.


There are a host of cool designs, with the Doja Exclusive Stacked Classic one of our favorites. This one is a limited-edition design with a capacity of eight ounces (130 grams). You can place your cannabis inside, tighten the lid and relax, safe in the knowledge that your marijuana is securely stored. These jars have a simple yet extremely effective design.

Final Thoughts on the Best Weed Containers

Overall, if you plan on storing your cannabis for any period, it is wise to consider investing in a container. Doing so will preserve the smell, taste, and potency of your bud. It also ensures that your marijuana’s odor doesn’t escape and fill your house!

The best containers keep your weed at the ideal temperature and humidity levels. They also protect it from the sun’s UV rays and ensure that oxygen doesn’t get in and ruin your herb. If it comes with a child-proof lid, all the better!
