Cannabis Storage Guide: How to Store Weed Properly - 420 Science

Cannabis Storage Guide: How to Store Weed Properly

We've come a long way since the days of old when someone would keep their weed stash inside a dinky little plastic bag. Luckily, for the past 14 years, people have been using 420 Jars. We know that those little baggies do practically nothing to help preserve our stash. Even though storage technology has improved so much, keeping your stash fresh still takes some care and has some best practices.

Use a 420 Jar for the Best Weed Storage

Mold can still develop when you have your cannabis correctly stored, which not only threatens the health of your buds, it can also affect your health negatively as well. Once your cannabis has been exposed to or has started growing mold, it is no longer safe to ingest in any way, shape or form. Smoking moldy cannabis is not the only kind of gross, but it’s terrible for you and can cause some severe health problems down the line, especially for those people who have already weakened immune systems or deficiencies.

The best way to prevent mold exposure on your cannabis is with the help of a 420 Jar and humidity regulating pack. An Integra Boost featured in both 8-gram and 67-gram packs, both of which when used together can help to make sure that your product is stored safely and protected from higher humidity levels and that unwanted mold growth. Additionally, the humidity packs come with indicator strips that let you know when the packs need to be replaced to help guarantee that the quality of your cannabis is protected.

Ideal Temperature for Storing Weed

Mildew, molds, and other organic matters thrive in temperatures between 77° and 86° F, so taking some necessary steps of keeping your stash in a cool, dark place will pay off over time. Higher temperatures over an extended period can lead to dried out cannabinoids and terpenes, which have taken months to develop, and when these oils and plant material get dried out, it can result in hot, harsh smoke. Nobody likes a harsh smoke!

Additionally, warm air holds more moisture content than cold air does. It’s also good to remember that lower temperatures help to slow the process of decarboxylation of those cannabinoids, which is the process that transfers THC-A into the psychoactive compound THC and eventually degrades into CBN. Some people might even think that keeping your stash tucked away in your freezer could be a good idea, but unless you want to make a bunch of kief, then you might want to think twice before keeping your stash in the freezer. Freezing temperatures cause the trichomes to become brittle and break off pretty quickly.

Protect Your Stash From Air and Light for Long-term Weed Storage

We recommend separating your daily stash from your long-term storage, and we would have to agree with that. Both short-term and long-term storage involve preventing air and light from reaching your buds. You should occasionally open your jar to introduce some fresh air now and then! Controlling the amount of oxygen and light that enters your buds helps preserve their potency and maintains their cannabinoid and terpene profiles.

It’s also a good idea to have a few different 420 Jars in your collection so that if you have different strains, you can keep them all separated. This is important to not only keep everything organized but to maintain the unique flavor profile of a specific strain as well. It’s worth mentioning that you should not keep your stash near your other smoking tools like pipes and grinders as ash and resin from burnt cannabis has a tendency to linger and will stink up your stash - in the worst way possible.

Those who travel and take their stashes with them should rely upon high-quality storage containers such as 420 Jars. Another excellent method of storage for your stash would be the Stashlogix Silverton Smell-Proof Combo Lock container. The special lining along the zipper and the rubber seal block odors to help keep you incognito while on the go. Also, harmful UV rays break down many organic and synthetic materials, and it only makes sense that storing your cannabis in a 420 UV Jar will help to keep control over the temperature of your stash and keep it out of the way of those dangerous UV rays. You wouldn’t want to expose yourself to UV rays unnecessarily, so the same rule should apply your stash!

To Sum It All Up


  • Keep your stash stored out of direct sunlight in a cool, dry place.
  • Use glass 420 Jars and keep a few different styles of 420 Jars to separate your strains to maintain their unique individual flavor profiles.
  • Use humidity packs like Boveda or Integra Boost to monitor and control RH levels.
  • Introduce some fresh air into your storage container now and then.


  • Keep your stash in the freezer. Unless you are trying to make kief, then, by all means, store it in the cold. Freezing temperatures cause the trichomes to become brittle and break off quickly.
  • Store in plastic bags or containers.
  • Keep your stash above or around electronics or appliances that give off heat.
  • Store grinders, pipes, or other paraphernalia with your cannabis.

Cannabis is not cheap, at least for the majority of us, so making sure that you store it properly is a huge deal. Nobody wants to throw money away, and if you have to throw your nugs out then that is pretty much what you are doing. Take care of your buds and they will take care of you, hopefully, these tips help you do just that.
