do cannabis seeds expire


When your beloved buds are grown, dried and cured , it’s very important to keep them in a particular place, following specific patterns, for them to be ideally preserved as long as possible .

Does marijuana get bad? What’s the expiration date?

Marijuana doesn’t expire , but, gradually, bud quality worsens – some curing months improve its quality, but, little by little, time diminishes its effects and flavor progressively; that doesn’t mean a crop kept along a year’s a bad crop, but it won’t have the aroma, flavor and effects of the first post-curing months .

How to preserve cannabis?

Many growers think that, when the buds are dried and cured, that’s it, and they don’t care about their proper storage – this post’s a brief overview on useful tips to keep your marijuana in top condition for a longer time . There are many ways to preserve marijuana – some growers prefer to keep it vacuum-packed, in glass jars or in tuppers.


The place where marijuana’s preserved has to be a tight package , away from oxygen direct contact – oxygen oxides the trichomes , and makes marijuana quality decrease constantly .


Weather conditions for marijuana preservation are fundamental – if exposed to high temperatures , marijuana will be harmed and the resin will be degraded , losing flavor, aroma and effect; marijuana will get too dried, lose its whole humidity and reduce its volume and weight – excess drying affects the smoker’s sensation, feeling like his throat scratched by the smoke .

Consequently, it’s suitable to keep marijuana at 15-25 degrees – if occasionally higher, no problem, but, if always higher, previously-mentioned feedback comes into play .


Humidity’s also a fundamental factor when preserving marijuana; if the buds are kept in a wet place, fungi will probably appear , so your crop would get impossible to be smoked – environmental humidity’s very important .

Besides, if humidity levels are too low , marijuana will get too dried , and this will also affect the crop quality negatively – average humidity parameters are a good way to keep marijuana in better condition for a longer time .


Light also degrades resin trichomes , and it affects marijuana quality negatively – for buds kept in top condition, it’s very interesting to find a dark space for the chosen container .

When Should I Start Buying Seeds for the Next Gardening Season?

For some, garden planning is a year-round affair. This is mostly because the United States is broken up into different parts known as growing zones. Depending on your growing zone, you may be able to grow and harvest crops outdoors no matter the time of year (like Zones 10-13). For others, gardening outdoors may only be possible for certain increments of time and therefore knowing when to buy seeds, and even when to start them, can be some very important information to have!

Good to know: seeds do not flat-out expire as time goes on.

What does happen to an aging seed, however, is simply that its rate of germination begins to diminish. This is a completely natural occurrence. Due to the fact that seeds do not expire, many gardeners will buy and/or collect seeds at any time and store whichever ones they don’t use.

Storing seeds is simple, you just need the proper storing conditions. Seeds should be stored in a cool (preferably below 50 degrees Fahrenheit), dark place. The moisture content within a seed greatly affects the seeds viability. Because of this, the level of moisture where your seeds are stored should remain relatively stable. You can keep seeds in their original packaging for identification purposes and then store them in containers. Many gardeners may use plastic containers or mason jars for seed storing. Whatever container you choose, be sure that it is airtight.

Don’t plan on using all of the seeds you’re buying? You can always store any of the seeds that you do not end up using right away.

With that covered, let’s get to the real question you came here for: When should you start buying seeds for your next outdoor growing season? The answer is really whenever you’re ready! But it doesn’t hurt to take these factors into account when buying seeds and planning your next garden:

As a general rule of thumb, you can start most seeds indoors 6-8 weeks before your areas final frost date. This means, for example, if you’re in growing zone 6b you can start your seeds indoors roughly around the beginning of March. Therefore, you could (and probably should) start buying your seeds around January and February! Buying your seeds sooner than that wouldn’t hurt either.

Keep in mind that some plants will not transplant well and should not be started indoors. This is where having the sowing instructions on your seed packet will come in handy. The sowing instructions on these types of plants will typically suggest you sow your seeds directly outdoors after threat of frost has passed.

This year, Coronavirus (also known as COVID-19) has changed many facets of life for people and gardening has not been excluded. In all actuality, many people have taken up gardening while they’ve been home adjusting to the new normal. The demand for seed starting supplies and seeds has greatly increased both in-store and online. Knowing this, we cannot guarantee that the seeds you’re looking for will be In Stock at all times (especially during peak season) so it may be a safe bet to plan on buying your seeds earlier than you’re used to for the 2021 season!

Expiration date: Can cannabis go bad?

On an episode of the PBS program “Antiques Roadshow” that aired in early April, the owner of a 100-year-old medicine cabinet received both good and bad news.

The good news? The cabinet, which contained 288 compartments designed to house herbs and/or roots that served as medicinal remedies, was deemed to be worth between $5,000 and $7,000.

And the bad? The contents of three of the compartments were missing, including the one labeled “cannabis sativa.” Turns out the brother of the cabinet’s owner had found the stuff and already smoked it.

News reports of the incident failed to say whether the brother ended up getting high.

But the story poses a good question: How long does cannabis retain its potency? And as with most everything else involving cannabis, the answer depends on a number of factors.

Let’s begin by referring specifically to actual marijuana leaves. As writer Miles Klee wrote the online magazine, “The fact is, no matter what some bro on a message board told you, weed is never going to expire or rot quite the way milk and meat do. It’s also not going to get significantly less potent or age like a fine wine if you hold onto it for a year.”

“Even so,” Klee added, “you might say that weed has something of an unspoken ‘best used by’ date.”

Leaves can dry out over time. What is most detrimental to cannabis leaves, however, is moisture, which can cause the growth of mold. So what is really important is to know how best to store your stash.

In a blog post last updated in February 2020, Namaste, a premium cannabis brand from the Canadian producer Zenabis, names four factors that affect cannabis’ freshness: humidity, light, temperature and air.

Humidity can cause mold, a problem that can lead not only to a bad taste but also to health issues such as headaches, vomiting and diarrhea. Light can break down cannabinoids, as can high temperatures (whereas cold can, again, lead to the growth of mold). And air can both affect taste and reduce potency.

The blog post lists various ways to “keep weed fresh,” but it really comes down to making sure your product is fully cured, stored in an air-tight glass (not plastic) container, and kept in a cool, dark place.

High Times, the magazine that calls itself “the definitive resource for all things cannabis,” echoes much of the above advice. As expected, though, the tips writer Nick Lindsey shared are even more, uh, “definitive.”

As for how long weed will be potent, Lindsey wrote, “If it’s been properly harvested, dried, cured and then stored, you can expect your weed to stay fresh anywhere from six months to a year.”

Yet since most people don’t, or can’t, replicate ideal conditions – especially involving light and temperature – Lindsey advises consuming your stash within that first six months.

Here are the specifics of that potency loss, according to the United Nations Office on Drugs and Crime: Weed loses “roughly” 16 percent of its THC after one year, 26 percent after two years, 34 percent after three years, and 41 percent after four years.

So, clearly, the sooner you consume your weed, the better.

But, then what about other cannabis products? No longer limited to flower for homemade joints, bongs or brownies, the legal cannabis market has multiplied the ways cannabis can be consumed – edibles in all flavors, tinctures and topicals, wax with a dab rig. And all of it must be packaged with precision by meticulous processors under the watchful eye of the Washington State Liquor Control Board (edible processors are additionally regulated by the Department of Agriculture).

For edibles, High Times advises, keep them in their original packaging and, as with weed, store them in an enclosed space, away from light and high temperatures. The same holds for concentrates – oils, tinctures, resins, etc. – with the proviso that you place them in “small containers designed specifically for dabs.”

And vape pens? No need to worry about humidity or exposure to air, since the pens themselves are airtight. But direct sunlight can be a problem. In addition, Lindsey wrote, consider standing your vape pen upright “as this will keep all the oil at the bottom of the cartridge, ready for immediate use.”

That, then, is your basic guide to protecting the potency of your cannabis. Here, though, is a final bit of advice, which is just common sense:

Whatever method you choose to store your stash, keep its location a secret from your brother.
