The Ideal Storage Environment

The storage of cannabis is important to ensure the freshness and potency of your product. The best way to store cannabis is in an airtight container in a cool, dark, and dry place. Doing this will help to maintain the quality of your cannabis.


Cannabis should be stored in a cool, dark and dry environment – think of it like wine. The ideal storage temperature for cannabis is 12°C with humidity levels between 58-62%. If your stash is too humid, your weed can grow mold and mildew, which can spoil your weed and make it unsafe to consume. If your stash is too dry, the THC can degrade, making your weed less potent.


Too much light exposure will degrade THC into CBN, so it’s important to keep your weed in a dark place. The ideal storage environment is in a dark room or container with a tight-fitting lid. If you must keep your weed in a spot that gets some light, make sure to wrap it in something opaque like tinfoil or black paper.


Cannabis should be stored in an environment with 50% relative humidity (RH), plus or minus 5%. If RH falls below 40%, the cannabis may become too dry and start to degrade. If RH rises above 60%, the cannabis may become too humid and start to degrade.

The “right” humidity level for cannabis is a function of both the water content of the plant material and the temperature of the storage environment. As temperature increases, the amount of water that can be held in the air (the vapor pressure) also increases. This is why cannabis should be stored at cooler temperatures, even if it means slightly higher humidity levels.

While 50% RH is ideal, a range of 45-55% RH is acceptable. If you can’t maintain this range within your storage environment, it’s better to err on the side of slightly too dry (45% RH) than too humid (55% RH).

The Best Storage Containers

Cannabis storage is essential in order to keep your weed fresh and potent.You may have heard that the best way to store cannabis is in a glass jar, but there are actually a variety of different storage containers that will work. Choosing the right storage container is important so that your cannabis stays as fresh as possible.

Glass Jars

Glass jars are a popular way to store cannabis because they protect against light, are airtight, and don’t absorb smells. They also allow you to see how much cannabis you have left. If you choose to use glass jars, make sure they have a wide mouth so you can easily get your cannabis in and out of the jar. Be sure to wash and dry your jars before using them. You can sterilize them by boiling them for 10 minutes.

Mason Jars

Mason jars are a longtime favorite among canners, and they work just as well for storing cannabis. They come in a variety of sizes, so you can choose one that’s just right for your needs. Be sure to clean the jars thoroughly before using them to store your cannabis.

Mason jars have a screw-on lid with a rubber seal that creates an airtight seal. This is important because it helps to keep oxygen out, which is one of the main enemies of fresh cannabis.

You can store your cannabis in Mason jars for up to six months without any problem. Just be sure to check the seals periodically to make sure they are still airtight.


Tupperware is an excellent storage option for cannabis. Unlike jars, which are made of glass and can break, Tupperware is made of durable plastic that will keep your weed fresh and ensure it doesn’t get damaged. Plus, Tupperware has tight-sealing lids that will keep your weed from drying out.

Silicone Bags

Silicone bags are great for cannabis storage because they are airtight, moisture-resistant, and durable. They can be sealed shut with a zipper or zip-top, and some even have a built-in vaporizer to help preserve your weed’s terpene profile.

Mylar Bags

Mylar bags are the preferred storage method for most cannabis consumers. They are made of a material that is impermeable to air and moisture, which makes them ideal for long-term storage. Mylar bags can be sealed with a heat sealer or an impulse sealer and are available in a variety of sizes.
-1/8 ounce (3.5 grams)
-1/4 ounce (7 grams)
-1/2 ounce (14 grams)
-1 ounce (28 grams)

Mylar bags are also popular because they are lightweight and easy to transport. They can be stored in a variety of locations, including a cool, dark closet or drawer.

If you’re only planning on storing your cannabis for a few weeks or less, then keeping it in a glass jar is perfectly fine. Glass jars with airtight lids work great because they keep your cannabis dry and away from any light. And depending on the size of the jar, you can store anywhere from a half ounce to multiple ounces at a time.

To ensure your cannabis stays fresh, make sure to store your jars in a cool, dark place like a cabinet or closet. Avoid storing your jars in the fridge or freezer as this can cause them to become too moist which can lead to mold and mildew growth.

In a Mason Jar

Storing your cannabis in a mason jar is probably the most common way people store their weed. It’s quick, easy, and you probably already have a few laying around your house. All you need to do is put your weed in the jar, screw on the lid, and voila! You’ve got yourself a airtight container that will keep your weed fresh for months.

Short-term storage of your stash is key to maintaining cannabis freshness. But how, exactly, should you be storing those precious nugs? We consulted some experts to get their take on the best way to store your cannabis for short-term use.

Tupperware Container
“The best way to store your weed long term is in a plastic tupperware container with a lid that seals shut,” says Evan Marshall, co-founder and CEO of Marshall Grinder, a cannabis storage company. “This will keep your weed at the perfect humidity level and prevent it from drying out.”

Mason Jar
“For those who prefer glass jars, mason jars are a great option for short-term cannabis storage,” says Joe Lindsay, head of horticulture at Helix TCS, a provider of ancillary products and services to the legal cannabis industry. “To avoid damaging your jar, be sure to wrap your cannabis in something soft like parchment paper before placing it inside.”

In a Silicone Bag

If you only plan on storing your cannabis for a short period of time, then keeping it in a silicone bag is your best option. You can find these bags at most head shops, or online. Place your cannabis in the bag, and make sure to squeeze out as much air as possible before sealing it. Store the bag in a cool, dark place, and your weed should stay fresh for up to a month.

In a Mylar Bag

When you first get your cannabis, it’s moist and fresh. If you plan on consuming it within the next few weeks, then you can store it in a Mylar bag. Place your weed in the bag, and squeeze out as much air as possible before sealing it. Then, store it in a cool and dark place like a drawer or cupboard.

Storing Cannabis for Long-Term Use

When storing cannabis for long-term use, it is important to keep it in an airtight container in a cool, dark place. This will help to preserve the THC and other cannabinoids so that the cannabis will remain potent for a longer period of time. Mason jars are a popular option for storing cannabis, but any airtight container will do.

In a Glass Jar

One of the best ways to store your cannabis is in a glass jar. Glass is non-porous, so it won’t absorb any smells from your cannabis. It’s also airtight, so it will keep your cannabis fresh for a long time. Make sure to get a jar that has an airtight lid, such as a canning jar.

If you live in a hot climate, you may want to store your cannabis in the fridge or freezer. Cannabis can go bad if it gets too hot, so this will help keep it fresh. Just make sure to take it out of the fridge or freezer a few hours before you plan to use it, so that it has time to come to room temperature.

In a Mason Jar

Preserving your cannabis for long-term storage is easy if you follow these simple steps. Cannabis will stay fresh for a long time if it’s stored in a cool, dark place in an airtight container. We recommend using a mason jar for storage.

– Firstly, make sure your mason jar is clean and dry before use.
– Secondly, fill your mason jar with cannabis buds, making sure to leave enough room at the top of the jar for air circulation.
– Next, seal the jar tightly and store it in a cool, dark place away from direct sunlight or excessive heat.
– Finally, check on your cannabis periodically to make sure it’s still fresh and remove any buds that have started to deteriorate.

Storing your cannabis in a mason jar is an effective way to keep it fresh for long-term storage. By following these simple steps, you can ensure that your cannabis will remain potent and enjoyable for months or even years to come!

In a Tupperware Container

When it comes to storing cannabis, an airtight tupperware container is your best friend. Make sure to press as much air out of the container as possible before sealing it shut. For extra freshness, you can also throw in a dessicant pack (like the ones that come in shoe boxes). Just make sure that the dessicant pack is in a separate ziplock bag so that it doesn’t come into direct contact with your weed.

In a Silicone Bag

Cannabis silicone bags are airtight, flexible, and heat-resistant, making them ideal for storing cannabis. They come in a variety of sizes and can be found at most headshops or online retailers. Cannabis stored in a silicone bag will stay fresh for several months.

To store your cannabis in a silicone bag, simply place the buds in the bag and squeeze out as much air as possible before sealing the bag. For best results, store the silicone bag in a cool, dark place like a closet or cabinet.

In a Mylar Bag

If you’re going to store your cannabis for more than a month or two, you’ll need to take some extra steps to make sure it stays fresh. One of the best ways to do this is to store it in a Mylar bag.

Mylar is a special kind of plastic that is very good at keeping out light, air, and moisture. All of these things can cause cannabis to degrade over time, so by storing it in a Mylar bag, you can help it stay fresh for months or even years.

To store your cannabis in a Mylar bag, simply place the buds in the bag and seal it shut. You can then store the bag in a cool, dark place like a closet or drawer.

If you’re storing cannabis for long-term use, you may also want to consider adding a desiccant packet to your Mylar bag. Desiccant packets are small packets that contain materials that absorb moisture. By adding one of these packets to your Mylar bag, you can help keep your cannabis even drier and further extends its shelf life.
