So far, we’ve been taught that cannabis buds are fragile and need an optimum environment so they can be enjoyed properly. But what if we tell you that one of the best ways of experiencing cannabis requires you to freeze your buds?
But, surely, freezing would destroy the buds, wouldn’t it?
Not really. As long as you do it properly, your buds are safe — safer than they will be out in the open. Essentially, by freezing cannabis buds, you can preserve their terpenoid and cannabinoid profile unlike ever before to create super-potent cannabis extracts. This is called fresh frozen cannabis.
Read on to know all about fresh frozen cannabis and how you can use it to create one of the best cannabis extracts — live rosin — from the comfort of your home. And you won’t have to spend a lot of money, either.
In simple terms, fresh frozen cannabis is nothing but freezing freshly harvested buds — once you harvest the buds, you immediately seal them in bags and place them in sub-zero temperatures for some time.
Yes, this process sounds risky and weird, but this is a process that many pro growers swear by because it offers various benefits that are simply not possible with regular, unfrozen cannabis buds.
During the fresh frozen process, you harvest the buds when your plant is mature and immediately freeze them. This process saves you a lot of time and labor associated with the curing and drying process of the buds.
Additionally, it can help you create potent concoctions with your buds. Unfrozen buds lose a lot of terpenes and cannabinoids during the drying and curing process, and more is lost over time as these compounds degrade due to environmental factors. But by freezing fresh buds, you get to preserve the cannabinoid and terpene content.
You might be wondering, is freezing risky for your buds?
Yes, the process of freezing cannabis is sometimes risky — but only if you don’t know what you are doing. It is crucial to keep in mind that freezing fresh cannabis buds is still in its infancy, but you can do it with the right steps without worrying about the risks.
Since fresh frozen cannabis is a relatively new process, growers are still experimenting with it. However, so far, it has helped growers produce some of the most potent cannabis extracts out there thanks to the rich terpenoid and cannabinoid profile that would otherwise have been lost.
The two most popular examples are live resin and live rosin, which you can dab, vape, add to edibles, and even roll a joint if you’re feeling adventurous. They get their names thanks to their freshness and the process growers use to produce them.
Live resin is created using hydrocarbon solvents like butane and propane, which are later purged from the extract — the residue is live resin. On the other hand, live rosin involves a solventless process that uses low pressure and heat. The latter is an easier process that even a home grower can use with ease. More on this is below.
Fresh frozen cannabis offers various benefits to you, two of which were briefly discussed earlier. But now, let’s look at the benefits in detail. Here are the benefits of fresh frozen cannabis.
We all know how time-consuming and tedious the curing and drying process is, and let’s not even forget — we have freshly harvested our buds but still have to wait for a few weeks at least.
But thanks to the freezing process, you don’t have to worry about all that. For a grower, especially a commercial one, you can enjoy your cannabis buds a lot faster with fresh frozen since you no longer have to spend the time and labor curing and drying them.
Terpenes and cannabinoids — the two phytochemicals are the reason we grow cannabis, but they can degrade over time. Here, cannabinoids are more stable, but terpenes tend to degrade a lot faster once you harvest the buds.
Terpenes are volatile hydrocarbons, sensitive to light, oxygen, and temperature, and they are also quite fragile so you may damage them while handling your buds. During the drying and curing process, where your buds are exposed to the environment, they end up losing a lot of their terpenoid profile.
Similarly, cannabinoids can also degrade over time. For example, your buds will retain THC for up a year, after which they will start losing most of their THC content. This occurs due to environmental factors like light and heat.
Here, freezing freshly harvested buds minimizes the cannabinoids and terpenes’ exposure to harsh environments, protecting them over time.
The curing and drying process is usually a hit or miss because it relies on various environmental factors that may not always be ideal in your region. For example, if you live in a humid region, you have to worry about mold, but in a cold region, you have to worry about frost.
While you can still produce high-quality products with the right steps, it takes a lot of effort and the quality is generally not consistent.
In that case, you can simply freeze your buds to save yourself the time and your buds the risk. This allows you to create high-quality products with a consistent quality standard.
Have you ever grown more cannabis than you can consume and some of the leftover stock was wasted? If this happens to you, you can freeze your cannabis buds to extend their shelf life.
For example, one Italian team of researchers studied the degradation of THC over four years in different environments — room temperature with light, room temperature with darkness, refrigeration, and freezing.
According to the study, the THC of the buds at room temperature had completely degraded in four years whereas the frozen buds had their THC content almost intact.
Do note that there is a lot of debate on how long the buds should be frozen for storage. According to the research, freezing can preserve your buds for years but don’t wait five years before consuming them. It’s better to be safe than sorry.
While not a lot of growers use the fresh frozen technique over traditional curing and drying, you would be surprised to know that the former is actually the easier technique of the two. Let’s take a look at how to create fresh frozen cannabis at home.
You first need to ensure you have all the right supplies, but unlike curing and drying, fresh frozen does not require a lot of equipment, to begin with. It is more than likely that you already have all you need for this process. Here are the things you need.
It isn’t called fresh frozen for no reason, so the first thing you need is freshly harvested cannabis buds. Ideally, you need to freeze them as soon as you harvest them, so timing is important here.
Here, you can use any strain of cannabis, depending on the terpenes and cannabinoids you want to experience in your final extract. However, you should only use buds that are free of mold or pesticide residue to ensure a safe experience.
An important part of the fresh frozen process, a freezer is where you will be storing your freshly harvested cannabis buds. But don’t worry, you don’t need a fancy freezer like a walk-in one in your favorite restaurant. A regular home freezer works just as well.
As long as your freezer reaches 0°F, you are good to go.
You shouldn’t toss your buds in the freezer. Instead, you need to pack them in plastic bags so they don’t get contaminated by other items in your freezer. An ideal choice here is to choose food-grade plastic bags, like turkey bags since they don’t leech much plastic and are safe for food.
If you want to take your fresh frozen cannabis to the next level, you can even invest in a vacuum sealer. But this is optional. You can use this sealer to pack your buds in a vacuum, making the bags smaller and free of oxygen, to avoid terpene degradation.
Once you have everything ready, you can start harvesting your buds. But be super meticulous during the harvest. Use sharp scissors to snip them off the branches and collect them in a tray.
And when handling your buds, you must be gentle so you don’t accidentally damage the trichomes on the buds. Ideally, you should hold them by their stems while wearing disposable gloves.
Next, you should trim your buds by cutting off sugar leaves. You can use these to prepare sugar leaf tea or kief.
Once the buds are manicured, you need to place them in a bag. Do note that you need to go from harvesting to bagging in as little time as possible. And if you are using food-grade plastic bags, fill them up to 75%.
Before sealing them, gently squeeze the bag to get all the extra air out, but don’t squash the flowers. Here is where you can also use a vacuum sealer to get all the air out, but that is optional.
Finally, you can freeze the buds by placing the bags in your freezer. Store the buds under 0°F, but you can go lower too if your freezer allows it. Anything above 0 degrees is not recommended.
Once you close the freezer, you need to be patient and avoid disturbing it for at least 24 hours — your buds need to be completely frozen, and cracking the freezer open during the first 24 hours may lengthen the freezing time.
Also, there is no rush to process the buds now since they can last for literally years once they are frozen over. So, use this time to research and perfect the next steps, and then you can start processing your buds.
When you’re freezing your cannabis buds, you need to keep a few things in mind to ensure safe and optimal freezing. Here are a few tips for the same:
When it comes to fresh frozen cannabis, you have two ways of extracting all the goodies from the buds — live resin, a hydrocarbon extraction, or live rosin, a solventless extraction. Both have their pros and cons, so let’s take a look at them below.
The production of live resin uses hydrocarbon extraction, i.e., you have to use hydrocarbon solvents like butane and propane. During this process, the resin is extracted using a closed-loop system, followed by purging to remove the solvent from the extract.
And depending on your goals, you can dewax or winterize the extracts, too.
However, this process of using a closed-loop system is relatively young — perfected in 2013 by William “Kind Bill” Fenger. Before him, extractors used an open blast system that produced subpar results.
For home growers, live resin isn’t the ideal way to go because it requires commercial-grade machinery for closed-loop hydrocarbon extraction, which can be super expensive. Plus, it requires volatile solvents that are usually not safe to use without the right equipment and processes in place.
On the other hand, you have the solventless extraction used to produce live rosin. To create live rosin, you first need to create bubble hash or ice water hash — doing so gives your product a better flavor profile and quality.
And if you know anything about cannabis concentrates, you would know that bubble hash is the best way to extract frozen cannabis since no other method can come close to preserving the phytochemicals as this process does.
Bubble hash can preserve the phytochemicals efficiently as the plant matter stays frozen during the entire extraction process. During this process, the buds are removed from the freezer and dipped into freezing cold water, which separates the trichomes, which are later filtered and isolated inside a bubble hash machine. The resulting hash is then refined into rosin.
If you are a commercial grower, this is the way to go as users are willing to spend more on live rosin because of its higher quality and flavor profile.
Just remember that you ideally shouldn’t produce live rosin without an ice water bath — the result will be a soupy mess, not rich live rosin. This is because the water cells tend to burst easily, leading to a soup. Instead, you want to press dry plant matter to get the rosin out.
Plus, producing live rosin is a lot easier for most people as it does not require commercial-grade equipment. You can do this with just a hair straightener and parchment paper!
What makes live rosin so desirable is its almost pure flavor profile, but what makes it an ideal option for home growers is how easy it is to produce at home. All you need is some fresh frozen buds, a hair straightener, and parchment paper. Follow these steps to make live rosin with fresh frozen cannabis at home.
Fortunately, to make live rosin at home, you don’t need any fancy equipment. All you need is the following:
The first step in creating live rosin is to create a bubble hash, and you shouldn’t skip this step if you want your rosin to look like rosin and not soup. This is because cannabis buds are 63% water, which leads to the rosin being more viscous — not desirable.
Follow these steps to create bubble hash:
There you have it, your homemade bubble hash.
Remember to not let your cannabis buds thaw when you take them out of the freezer. You need to keep the entire process as cold as possible.
Once your bubble hash is dry, you can now extract rosin from it. For this process, you need parchment paper and a hair straightener. Follow these steps to extract live rosin from the bubble hash:
You can store it in a cool, dry place. And to use your live rosin, you can add it to your vape cartridge, dab some on your joint, or just dab it. Just remember that this will be potent, so start low and build your way up. It will be worth it.
Fresh frozen cannabis is a relatively new technique that is gaining a lot of popularity nowadays. Yet, not many cannabis users know about it — only growers and sellers know about this process.
But if you want to consume cannabis in a cheap yet effective way, you should go with fresh frozen cannabis. Not only does it save a lot of time in curing and drying, but it also allows you to consume most of the terpenes and cannabinoids your precious plant produced for you.
The process is straightforward — freeze your fresh harvest cannabis buds for some time, remove them and dip them in ice water to create bubble hash, and gently squeeze bubble hash using a hair straightener and parchment paper to create live rosin. That’s it.
