14 Best Weed Jars and Storage Containers for Weed in 2020
There are many options when it comes to storing your cannabis and keeping them potent and clean. Over the years, many cannabis growers or users have eventually learned the importance of storing weed the right way. The most common method among growers used to be storing weed in large plastic garbage bags, then putting them inside tubs or bins. But eventually, many growers have realized that their storage method isn’t exactly pertinent to their process. Which is why buds are extremely dry or weak when you get them. Many cannabis growers also longed to secure more reliable and sealed storage since some states mandate that the cannabis is kept in airtight and properly sealed jars or containers. Proper and appropriate weed storage method should help mitigate the evaporative loss of potency or drying out. In writing this post, we carry the goal of being able to provide you with great choices for weed jars and best storage containers for weed.
Ideal conditions for storing your weed
Best relative humidity (RH) for storing Cannabis
Relative humidity (RH) is the ratio of the partial pressure of water vapor in an air-water mixture to the saturated vapor pressure of water at a prescribed temperature. The best relative humidity when it comes to storing cannabis is 55% to 62% RH. Studies have shown that cannabis will retain a higher terpene and cannabinoid content when this range of moisture is present for a prolonged period of time. Storing your cannabis in this RH range will surely retain a more robust flavor and a great high.
Ideal Temperatures for Storing Cannabis
Fungi and bacteria are very harmful not only to cannabis but to other plants as well. They promote the growth of mold and mildew and you would never want them on your cannabis. These molds grow at temperatures above 75 degrees and these harmful organisms can ruin your weed. That is why your cannabis needs to be stored at temperatures below 75 F or 24 C. Find and store them in an area where the temperature doesn’t fluctuate too much but remains around 65 F, or within ten degrees of 65 F at all times. This can be in areas such as a cupboard, drawer, or closet.
Previous conducted studies like “The Stability of Cannabis and its Preparations on Storage,” conducted by J.W. Fairbairn, J.A. Liebmann, and M.G. Rowan from the Pharmacology Department in the School of Pharmacy, University of London in 1975 found that that the best long-term weed storage method required keeping cannabis at room temperature in a dark and sealed container. It is ideal that you limit light exposure to weed that you intend to store. Light is actually considered to be the main factor that causes weed degradation. UV rays and intense light from many sources will break down cannabinoids. Therefore, choose a dark place to store your weed, a closet or drawer that doesn’t receive much light. Also, use a dark glass container when storing batches of your weed.

Some weed users and growers may not trust the use of vacuum sealing when it comes to storing weed. While some claim vacuum sealing, properly, with plastics which don’t contain BPA, is a great way to keep your bud fresh for a very long time. Others claim that plastic will ruin your weed and vacuum sealing will suck out your cannabinoids and damage your trichomes. Although, you can vacuum seal smaller individual doses, then store the individually sealed doses in a glass jar in a cool dry place so that it is still protected from temperature extremes and light exposure. You could even use a light-resistant plastic; however, you would need to be extremely careful to know the chemicals in your plastics because they can end up in your weed.
Weed storage Dos and Don’ts
- Remember to use an airtight container. A clear mason jar will be okay but remember to store it in a dark cupboard or cabinet.
- Keep your stored weed away from light.
- It is ideal to use containers made of materials with a neutral electrical charge. An example is a glass jar. This is to avoid static.
- Always keep different strains in separate containers to avoid mixing chemical compounds and aroma.
- Store filled containers in a cool and dry place. It should be at 70 degrees Fahrenheit and away from direct sunlight.
- Maintain an optimal range of 55% to 62% relative humidity (RH) in the storage container.
- Maintain relative humidity by using Boveda packs or VaporBeads.
- Store weed inside a chiller or freezer. This will result in dry, brittle, and tasteless weed.
- Keep weed in tin cans. These tin cans let in too much oxygen, which degrades THC over time.
- Store your weed without a humidity element.
- Keep weed in sandwich bags. The plastic has static that will pull off the trichomes, which contain the cannabinoids.
- Add fruit and mix them inside your weed jars. This will eventually create a too high RH and will result to molds in your buds.
- Use sandwich bags for storage, they generate a static charge and will result in your buds having an unpleasant plastic taste. Your weed will also be smelled since they are not airtight.
- Keep near heat and electricity sources. They will dry out your cannabis.
- Pre-grind and store for a very long period of time.
Things to Consider Before Buying a Weed Jar or Storage Container
There are a few things to consider before you invest in one of these products. Below are some aspects to keep in mind to ensure you invest in the right model.
An important thing to consider is the size of the weed jar or storage container. Sometimes these products might be too big or too small for your needs. Because of this, it’s ideal to closely look at the size. For instance, if you plan to have a lot of weed on hand and don’t want to transport it around, a larger jar or container might be best. On the other hand, if you want a jar or container to carry around with you in a bag, a smaller and more compact size might be ideal.
If it’s Airtight
You should also always make sure a weed jar or storage container is airtight. This will prevent moisture from seeping into it which can ultimately destroy the contents inside. Moisture can invite mold and harmful bacteria as well as reduce the flavor of your weed. Due to this, always make sure the jar has an airtight lid.
If it Protects Your Weed From Sunlight
Just as with moisture, sunlight can also be a problem. The UV rays emitted by the sun can cause your the color of your weed to fade which ends up leading to it being less flavorful. If you plan to keep your weed jar or container in a sunny spot, it’s a good idea to make sure it has a UV protection feature.
If it’s Smell-Proof
Another thing to consider is if the model is smell-proof. While a model might say it’s airtight, this doesn’t always mean it will help to prevent smells from escaping. Because of this, it’s important to ensure that the jar or container doesn’t leak smells when you use it.

Other Things to Keep in Mind
There are a few other things you’ll want to keep in mind before investing in a weed storage container or jar.
One is the price of the product. Depending on your needs, you’ll either want to invest in an affordable or expensive one. If this is your first time buying a weed container or weed jar, you might want to start out with a cheap one just to make sure it works for you. On the other hand, if this isn’t your first time, a more expensive one might be ideal.
Clean it Out
It’s always a good idea to make sure to clean your jar or container out often. This will not only help to prevent odors from forming, but can keep your weed fresh. Leftover particles inside might end up destroying the flavors of fresh weed. It can also be a hazard to your health as dangerous resin could coat the walls of the jar or container.
To clean out your storage container or jar, you can take a clean cloth or paper towel and wipe it out. This method is perfect if you don’t want to do a deep clean.
For a more intense clean, you can rinse the jar or container out under warm soapy water and then dry it out. Keep in mind though that this might not be possible for all container or jar types as it could ruin them. Because of this, make sure to check beforehand.
Be Careful with It
While these items are usually very durable, you still want to make sure to be careful with them. Too much bumping around could lead to scratches on its exterior ruining its appearance. It could also mean that the container or jar is more likely to fall out as it’s not being carefully watched. Due to this, just make sure to keep a close eye on it, or keep it in a special pocket or bag to help better protect it.
Don’t Put Extra Materials Inside It
As mentioned in the section in the beginning of this article, it’s a good idea to not put extra materials, like a plastic bag, inside of the product. This will not make it a bit harder for you to get your weed out, but could lead to static which can hurt the taste of the buds. It’s always important to put the weed inside of the containers or jars by itself.
Growing cannabis is not an easy task, and we know that. Which is why it is really important to store and keep them fresh in a good container. Finding a great stash jar or container might not be an easy task, especially for the beginners. However, we are pretty sure that after you read this post, you already have an idea which container is best for you. You have the option of choosing glass, metal or even plastic to store your weed. Storing your stash especially if you are a grower, using weed for medical purposes, or just a heavy stones, or someone who handles a large amount of weed is an important part of preserving the taste, aroma, and freshness of good cannabis. Therefore, invest in a good storage container to ensure you enjoy the full cannabis experience. Having a great permanent storage container also makes it more hygienic and easier for you to find your stash.

How long is my weed good for? Leafly’s guide to storing cannabis
At some point in our cannabis consumption, we’ve all asked ourselves, “How long is my weed good for?” Maybe you’ve found a few nugs tucked in your winter jacket from last year’s ski trip, or when harvesting a medical crop you may need a way to safely store the excess buds until you’re ready to consume the fruits of your labor.
Like a fine wine cellar or whiskey barrel, properly dried and cured cannabis is best when kept in a cool, dark place. While there is no steadfast expiration date for cannabis, if you store it well it should last about six months to one year before losing considerable potency and flavor.
However, before you spark up that old weed, there are a few key elements to consider when storing cannabis for any extended period.
Explore marijuana storage options
What’s the best way to store weed?
Ideal temperatures for storing cannabis
Mildew and other molds on cannabis and other organic matter thrive in temperatures between 77° and 86° F, so basic precautions of keeping your cannabis in a cool, dark place will go a long way. Excessive heat can dry out the cannabinoids and terpenes that have taken months to develop. When these essential oils get too dry along with plant material, it can result in a hot, harsh smoke.
Lower temperatures also slow the process of decarboxylation of cannabinoids, the process in which THCA converts into the intoxicating cannabinoid THC. THC eventually degrades into CBN, a cannabinoid with different effects and properties. Additionally, warm air holds more moisture than cold air, which brings us to the next consideration.
Humidity factors for cannabis storage
Humidity control is paramount to keeping mildew and other mold contaminants away from your cannabis. Keeping your cannabis stored in a controlled environment with the proper relative humidity (RH) ranges can be a bit of a balancing act, but the general consensus is to keep cannabis between 59% and 63% RH when stored to maintain and enhance color, consistency, aroma, and flavor.
Keeping your RH below 65% reduces the chances for mold to occur. However, if your RH drops too low, you risk your trichomes becoming brittle and drying out the essential oils.
Light settings for storing cannabis
Harmful UV rays break down many organic and synthetic materials. Similar to the way your grass turns brown at the end of a long sunny summer, or how a car’s paint begins to fade when it is not garaged, UV rays will degrade your cannabis over time.
A study conducted at the University of London in the 1970s concluded that light was the single biggest factor in the degradation of cannabinoids. The same study concluded that cannabinoids maintain stability for up to two years when stored under the proper conditions, though it can remain effective and safe to consume for much longer as the essential oils slowly break down over time. Storing your cannabis out of direct light will also help you control the temperature.
Air control for cannabis storage
Double-check jar tightness to ensure every terpene is conserved. (Leafly)
While cannabis needs oxygen during growing and curing, storing your cannabis in a container such as a Mason jar with just the right amount of air is crucial to keeping it fresh and true to its original form. Having too little air can greatly affect the relative humidity, especially if the buds are not completely dried before storage.
Too much air, on the other hand, will speed up the degradation process as the cannabinoids and other organic matter are exposed to oxygen. There are a variety of hand and electric vacuum pump attachments available for canning jars that will help you minimize oxygen exposure.
How to store your weed
Do – store out of direct sunlight in a cool, dry place
Do – store in containers with a neutral charge, like glass Mason jars
Do – use hygrometers or products like Boveda to monitor and control RH levels
Do – vacuum seal jars and containers to minimize oxygen exposure
Do – separate your strains to maintain their individual flavor profiles. Label them with a date using a Sharpie. It sucks when you mix up strains.
Do – look for the many exciting new ways to store your cannabis. The cannabis industry is growing every day, with new products and companies like Cannador and The Bureau designing solutions for all of your cannabis storage needs.
Do — not stress about storing weed. The best way to get the most out of your herb is to smoke it in a timely fashion!
How not to store your weed
Don’t – store in the refrigerator. The fluctuations in humidity and temperature can actually increase your chance of mold and mildew. If you do refrigerate, vacuum-seal completely. Cold buds will scavenge water from the air, ruining the flavor. Allow container enough time to return to room temperature before re-opening.
Don’t – store in the freezer. Freezing temperatures cause the fragile trichomes to become brittle and break off like little icicles when handled. If you do freeze, vacuum-seal completely and keep frozen. Since a frozen bud scavenges water from the air, ruining the flavor, allow frozen container and buds enough time to return to room temperature before re-opening.
Don’t – store in cheap plastic bags or containers. Plastic often has a static charge that can attract precious trichomes. If you must use a plastic bag, only use it for short-term storage of small quantities of cannabis. Or use a higher-quality bag like a Smelly Proof bag.
Don’t – store above or around electronics or appliances that give off heat. Heat rises—instead, store your cannabis in a low cupboard, shelf, or in the basement of your house, much like a wine cellar.
Don’t – use a tobacco humidor. Most use cedar wood, which has oils that transfer and can influence the flavors of your cannabis. They also tend to employ sponges that use propylene glycol to regulate humidity and can oversaturate your cannabis.
Don’t – store grinders, pipes, or other paraphernalia with your cannabis. The ash and resin from burnt cannabis tends to linger and will stink up any storage container. Also, it is simply good etiquette to keep your supplies separate and clean.
Other factors for storing your marijuana
Products infused with cannabis, such as edibles and other perishable creations, will have different storage guidelines. Use by expiration date. Keep locked in a container to avoid accidental cannabinoid exposures. Refrigerate as directed.
Alcohol tinctures and other cannabis concentrates also degrade based on heat, light, humidity, and time. Keep extracts sealed tight in their containers in a cold, dark, dry place. While flower shelf-life is usually measured in a year or less—extracts and tinctures can be fridge-stable for years.
