Freeze wet cannabis seeds

Freeze wet cannabis seeds

Come and learn with us how to store your cannabis properly – whether in seed, flower or hash! We will explain everything about this subject so that your herb is always well preserved.

One issue that raises a lot of doubt is the best way to store cannabis so that it is kept in its best condition – after all, one of its biggest enemies is mold, which can ruin everything! And it’s not just the buds that deserve special attention – the seeds and the hash also need a place that is safe from moisture, light and any factor that might decrease its quality.

So, do you want to find out how to store your cannabis in the best way? We explain here how to do it correctly!

Conserving seeds

Did you buy the seeds, but you still don’t want to germinate, or do you want to germinate only a few? Cannabis seeds should be stored in a cool, dry place, with no interference from light. Whether you store your seeds in a freezer, refrigerator or even in a cupboard or drawer, it’s important to leave them there until it’s time to germinate. Rapid temperature changes can damage its genetic integrity. We recommend that they stay in the refrigerator till it’s popping time.

You have a few options to make sure they stay fresh until they germinate:

Seeds stored in a cold, dark environment, such as a refrigerator drawer.

Will you store them for just a few months? A plastic bag like Ziploc can be perfect, or airtight glass jars.

For longer storage, a vacuum-sealed package can be safer!

When keeping seeds in the refrigerator, keep them on the drawer or deeper in the fridge as possible so that they are not exposed to changes in temperature when the door is opened.

It is also important to note that by freezing the seeds, whenever they are defrosted and returned to the freezer, they become less viable.

When cannabis seeds are stored properly, they can last up to 10 years!

Where to store your dried cannabis

If you have dry buds or even brick weed, the way of storing may be a little different. There are a few options to ensure that it is always good when you want to use it to roll that beautiful joint:

In glasses

Glass is great for storing almost any type of substance, as it is inert, hard and non-biodegradable. The downside is that most glass jars are clear and light degrades trichomes – which does not matter if buds or dry cannabis are stored in the dark.

Buds stored in airtight glass can.

To store buds exposed to light, it is best to use UV glass. Our tip here is to choose a jar with an airtight lid! The less air, the better for the conservation and storage of your plant.

In stainless steel jars

Stainless steel pots, also with hermetic seals, are popular because they are strong and can be stacked. Metal does not interact with cannabis and is impervious to outside air – which guarantees good conservation. In addition, neither moisture nor light can penetrate them.


Not all types of plastic are recommended! Cannabis is slightly acidic and lipophilic, so it degrades some of them. Ziploc bags are popular because they don’t let odors pass, and are inexpensive. However, they are easily pierced by rods and do not provide protection against agitation and movement, which leads to further damage. Our suggestion is to use it only for seeds.

Desiccants: an important addendum

A desiccant is a substance that removes moisture from the surrounding air. Do you know those little bags of silica that usually come together in tennis boxes or bags? They are important to prevent moisture in transport, that can cause the goods to mold! Packets of silicone, newspaper or anything extra-dry acts as a desiccant and absorbs moisture in a storage container, and are good accessories for storing your cannabis.

There is a huge discussion about the use of this strategy. Some growers say it changes the taste too much, or that it even dries the plant too fast. The important thing is to try out on smaller scales so you can feel if you like it! Testing things is important before you put your whole headstash with it!

Vacuum packaging

Vacuum packaging is popular because it decreases the amount of oxygen present in packaging. Oxygen is corrosive and degrades the color of cannabis. The diminished presence of oxygen also discourages the growth of bacteria, but not anaerobic bacteria. Anaerobic bacteria thrive in environments with little oxygen or no oxygen, moist and with food. So never close and store wet cannabis!

Fresh cannabis? Learn how to cure it!

If it is a freshly picked bud, or even wet hash – ideally it should go through the drying and curing process. Drying means reducing the bud’s water quantity to 10-15%, depending on the desired crispness of the product. It also ensures that your cannabis becomes more stable, so that its properties are transformed – without being lost.

Here on the blog, we have already published an article by the wonderful Ed Rosenthal, a true cannabis expert, talking specifically about how to dry and cure your buds. Here, we will resume some main points with you:

There are several ways to do the curing and drying process, and one of the main ways is to use a climate controlled space. The space should be lit with green lamps, either fluorescent or LED, as the green spectrum does not change the material of the plant. The temperature and humidity must be constantly controlled and adjusted, and the air exchange calibrated to the desired volume.

For the first three days, a temperature of 68°F (20°C) and a relative humidity of 55% will ensure that the bud is left with approximately 30-40% water.

After that, the temperature should drop a few degrees to 64°F (18°C) to slow down the process. Another critical factor is the humidity of the air: if it is below 50%, the buds will dry out too quickly. A timer and an air control system, with a humidity controller, can help in this process, which should take between 10 and 14 days for the perfect taste.

Taste is not the only variable affected by the drying process. The effect that the bud will have on the body can also vary. The longer the bud dries, the more THC will turn into CBN and other cannabinoids. So, even talking about the same strain, the effect can be stonier or more agitated, raising or lowering the agitation. The difference between drying for 10 or 14 days is not evident for newbies, but for a connoisseur, there will be a world of difference.

The process of curing cannabis is similar to the aging process of a good wine. Ed explains that he cures cannabis by packing it in a wooden or cardboard box and pressing it lightly so that some of the trichomes break. After packaging, buds must be left in an environment of 18°C (64°F), with 50% relative humidity and total darkness for a period of 1 to 2 months. Check regularly to ensure the right conditions at all times. Make sure that the humidity remains between 45 and 50% to prevent the formation of mold and fungi.

How to store your hash

We also told here on the blog a special way to cure your hash. Like flowers, it can also go through this process, which further enriches substances. Curing your hashish, under ideal conditions, will preserve its flavor and smoothness and improve potency.

As with buds, the best way to cure the extraction is in glass jars in a cold, dry and dark place. The difference between them is that the flowers are ready in four to eight weeks, whereas for the proper cure of an extraction one can wait three to four months.

After that, to keep it, it is necessary to note that there are two main types: the hash made to cure, which is the most traditional, and the fresh hash, made with fresh frozen plants. Fresh hash, as it aims at the total preservation of terpenes, cannot be allowed to degrade – or, to put it simply, to cure it (unless it is cold cure, which is the subject for a next post). In the other case, the logic is the same as the cure of flowers: think about this slow degradation as a way to transform cannabinoids and terpenes in a positive way.

The ideal is to have an airtight pot, in a dark environment, with mild temperatures.

If it is frozen material, it is important to store it in the refrigerator; if it is a full melt, store it in the freezer.

The curing and drying process is not the same as storage, but they communicate to each other. Don’t let your hash over dry or even cure too much under poor conditions.

So, did you like these tips? Well, following these steps, we guarantee a well-preserved cannabis for the best joints of your life. Besides, nobody deserves to lose the herb for fungus, right?

Until next time, with more cannabis tips to improve life – and your high!

Should I Keep Weed In My Freezer?

Some people will tell you to freeze your cannabis or to store it in the fridge to “keep it fresh”. Of course, marijuana can be frozen but should it? The long and short answer is no.

Freezing your buds will not turn them purple or keep them fresh. They can turn purple from either their genetics or cold temperatures as they approach harvest but they won’t change color drastically after harvest. Green buds will typically get a little less bright green as they cure but none will turn purple after they’re chopped down.

I don’t ever recommend placing marijuana in a freezer or refrigerator. Freezing temperatures, fluctuating humidity and bright light all degrade THC and other cannabiniods. This will ultimately result in less flavor and potency.

The best place for storing pot is in a cool, dark place in a dark-colored or opaque sealed glass jar. Also, marijuana should really be consumed within a year or so of when it’s grown. Some connoisseurs have longer cured stuff that’s several years old, and it does take on interesting qualities as it ages, but ultimately, it eventually degrades. For every expertly long-cured, three-year-old bud I’ve smoked that burned perfectly and preserved the terpene profile, I’ve smoked far more old pot that’s simply past it’s prime. Besides, you can always grow more!

Farm to freezer: Why ‘fresh-frozen’ is taking over the cannabis harvest

Harvest season is upon us across North America and in the cannabis-growing heartlands of inland Northern California, there’s a new fall shortage: dry ice.

“It’s tough. The dry ice is gone,” said Alien Labs founder and operator Ted Lidie, when talking about harvesting three acres in Yolo County, California, this month.

Everyone freezes, that’s just what you do.

Ted Lide, Founder, Alien Labs

Over the last six years, the idea of freezing part—or all—of one’s cannabis harvest has gone from bizarre to mandatory. A full 30% of Alien Labs’ coveted new strain Planet Dosi is heading straight from outdoor fields into the freezer this year.

California’s largest cultivation licensee, Raw Garden, freezes 100% of their harvest, notes Jason Guillory, from Nug extracts of Oakland, a Raw Garden contractor.

Ben Grambergu at Grambergu Marketing in Northern California says: “A couple years ago, if you told someone you were going to freeze 100% of your crop, they’d tell you you were crazy. Now, we’re seeing 100% frozen harvests, and really large farms: 8,000-pound harvests. It’s totally taken over.”

Why frozen?

Demand for extracts

Driving this trend is consumers. They want pure, high-THC cannabis extracts in sleek vape pens that are easy to dose and don’t smell. Farmers have responded by buying up industrial freezers—plus using dry ice in the fields—and are sending the frozen crops straight to extract labs, skipping the traditional harvesting process.

Harvest cost savings

Freezing harvested cannabis can save lots of time, labor, and risk—and also money, says Ed Rosenthal, co-author of the 2017 crop science book Marijuana Harvest (this story’s author, David Downs, is Marijuana Harvest’s co-author).

Vigorous competition puts enormous pressure on farmers, squeezing their profit margins and making farming vastly more efficient. Fresh-freezing saves tons of cash on harvesting man-hours and drying rooms. “It eliminates whole steps,” said Rosenthal. “The more sophisticated the farmer, the more likely they are to do that.”

How farmers freeze

To get to pure extracts at low cost, farmers have flipped the millenia-old process of harvesting on its head.

Traditional methods

In the spring, farmers in the Northern Hemisphere sew the fast-growing crop. In fall, farmers harvest buds at peak ripeness, when aromas and cannabinoids—like THC—near peak levels.

You get smokeable flower by chopping down the ripe plant and air drying its buds in a cool, dry, dark room for about ten days. Weeks or months of curing can follow to perfect the smell and taste of boutique bud.

Traditional air drying is a battle against temperature and humidity spikes to avoid mold and fungus and preserve precious terpenes and THC.

Ditching tradition

But farmers are increasingly saying ‘Screw all that’ with fresh-frozen. They chop plants, remove the leaves, branches, and stems, and vacuum seal buds in thick plastic pillows weighing two to four pounds. Those pillows go into in an industrial freezer at -38°F, and the low temperatures lock in everything for processing at a later date: flavors and terpenes, cannabinoids (THC, CBD, etc.), as well as all the water.

“You’re not worried about degradation as much [in the plastic pillows],” said Grambergu. “The shelf life on that versus a regular pound in a turkey bag are very different.”

Getting from frozen buds to live resin

Next comes industrial solvent extraction.

Technicians finely grind the frozen buds into a powder, pack pounds of it in thick, stainless steel tubes, and blast a solvent like butane through it, which pulls out all the fresh-frozen terpenes and cannabinoids. Water crystallizes and separates from the plant material.

The result is a freezing cold, golden liquid. Technicians then purge the solvent, leaving behind concentrate, which is usually four or five times stronger than flower.

This extract goes into what’s taken over the concentrate scene— live resin , which is used in dab rigs and pens, as well as pre-filled live resin vaporizer cartridges like Loudpack’s Mimosa pod for the Pax Era. “Live resin is what’s driving this,” said Grambergu.

Live resin makes up some of the most aromatic cannabis products. And the smell is far less stinky than lighting up some flower.

“It comes down to ease of use,” Lidie said. “As new consumers enter the market, they don’t necessarily want to reek of pot… I can dab in my office and it doesn’t permeate through my whole home. If I smoke a joint, the whole house is going to stink.”

Effects from fresh-frozen extracts may be different too. Cannabinoids stay at peak levels with almost no degradation. Freezing preserves terpenes that would otherwise be lost to weeks of drying and curing.

“In general the feeling you get is revolutionary,” said Tracee McAfee, CEO of Cryo Cure, a Michigan-based cannabis freeze-dryer start-up. “It’s smooth, uplifting, sparkly, creative, and social, with no couchlock effect and no crash.”

More products beyond live resin

Beyond some of the best, terpiest dabs, fresh-frozen harvests help power the vast manufactured goods market for THC-infused food, drink, candy, topicals, and tinctures. Many farmers elect to send their entire harvest straight to oil, also known as distillate .

Fresh-frozen is changing cannabis farming beyond just growing for the dankest bud. Terrible-looking flower might have great terpenes and go into edibles. Farmers are sending the A-grade buds to the drying room, while freezing all the B-grade buds, small budlets, and re-growth on outdoor plants after the initial harvest, said Grambergu.

And farmers are moving past the annual harvest cycle in the fall to also grow small, short, winter cannabis crops in greenhouses just for extracts, said DiPaci.

Rosenthal notes that such manufactured products were the bulk of the market before prohibition began in the ‘30s. “The whole reason we got to smoking flower was because it didn’t require as much processing, which you could not do when it was illegal.”

“Instead of, ‘You grow weed to make pounds of flower,’ it’s, ‘You grow weed to make products—you grow weed to make cannabinoids, and to make terpenes.’ It’s not ‘indicas and sativas’ anymore,” DiPaci said. “It’s a way different landscape.”

The new frontier—live rosin

For some extract aficionados, mere live resin won’t cut it—they’ve moved onto live rosin, which comes from fresh-frozen cannabis extracts untouched by butane or any other solvent.

Company Paradiso has partnered with boutique brand Fields to release limited, artisanal runs of extracts using this process. Paradiso wet trims and freezes the best one percent of its harvest—its Grandiflora and Zkittlez strains—using a surge of 20 trimmers working fast, instead of the usual dry trim team of nine. “It’s much more labor intensive,” DiPaci said.

Companies like Blue River have perfected trade-secret techniques to extract cannabinoids and terpenes from frozen cannabis while leaving everything else behind. They’re using aspects of sublimation—where water gets removed through freezing instead of drying—and they’re using mechanical separation techniques. It’s very time-intensive and requires such high-quality materials that the resulting extract is worth four times more per gram than gold—for example, Synergy’s Strawnanna Mochi Flan is going for $165.

“It creates the best extract in the market. It’s much more labor intensive and there’s less return. That’s why it’s so expensive,” said Grambergu. “One of the coolest parts about cannabis is experimentation. Every farmer has always been curious about ‘What happens if you do this or that?’ Clearly freezing is one of the methods that has broken through and proven to be worth their time. I think we will continue to see farms move more and more toward this.”

Freezing cannabis harvests is a disruptive technology that’s here to stay.
