Freshly dried and cured cannabis flowers won’t stay fresh forever, but there are definitely some things you can do to keep them from going bad too quickly. The big culprits to avoid when storing your cannabis are light and air, two factors that will make your product taste different and degrade faster.
Today’s the day when plastic baggies and plastic pop-tops are no longer your go-to storage containers for cannabis. Though these can be great in a pinch and are good transport options, the static-y plastic will swipe THC-laden trichome stalks right off your bud and keep them stuck to the sides of the container. Not only are you losing trichomes and other little bits of your product to the sides and bottom of the container, but the porous nature of plastic means that you’ll be losing fresh scent and flavors (and therefore, terpenes) to the air.
And if you’re losing scent profiles to the air, it means you’re losing moisture to the air, as well. Even though drying and curing are hugely important steps for cannabis preparation, your cultivators are stopping the process at a very finely tuned point. Over-dried cannabis is crunchy in all the wrong ways, and burns harshly. Storing your cannabis in plastic, non-airtight containers is a surefire way to ruin the product you just procured. You (and your bud) are better off without them.
Glass containers are a much better option. They provide an airtight storage container that will prevent the oxidation that air exposure can cause, and the glass doesn’t get static-y like plastic. But clear glass will still expose your cannabis to light, which will cause the psychoactive THC in your product to slowly but surely degrade into CBN, a much less desirable cannabinoid that tends to subject users to the couchlock effect. (This is the same degradation reaction which cultivators want to avoid in our Science of Decarboxylation article.) This is easily combatted by wrapping your glass container in a towel or cloth that will block light, or simply storing your cannabis container in a dark spot.
Titanium, and nothing else (when it comes to metal).
Many metals will secrete flavor-changing gases over time. Titanium is the exception to this, so if you’re not into the glass container thing, titanium’s your best bet.
No paper. No aluminum foil.
No refrigerator. No freezer. No direct sunlight.
Let’s do this Goldilocks-style: not too cold; not too hot — just right, i.e. room temperature. Temperature fluctuations that are too hot or too cold will mess up the months of preparation that went into maximizing the cannabinoid and terpene profiles of your cannabis. Low temperatures will do weird things to the integrity of your trichomes, while high temperatures invite humidity and moisture that will assuredly attract terrible things like mold and fungus.
