Curing Cannabis: Why It’s Important and How to Do It Properly

Monday February 19, 2018

T here’s no one secret to producing great cannabis – the best cannabis is the product of premium genetics, careful cultivation, precise pruning, timely trimming and, finally, a slow-and-steady curing process.

The necessity of this last step should not be understated. A proper curing process (though timely and kind of boring) is key to producing that smooth, flavorful (and yes, more potent) smoke sesh that’s characteristic of only the finest green, and we’ll tell you exactly how to do it right. But before we do that, let’s look at why curing cannabis is so important in the first place.

Curing for Preservation Purposes

People have been curing their food for as long as there has been civilization. In fact, the ability of ancient humans to cure (and thus store) food for later consumption may have been the most important step to creating civilize societies.

No longer was it necessary to consume food as soon as it was harvested or hunted; food preservation via various curing processes meant people could reap bountiful harvest then save it for later instead of always having to be on the prowl for their next meal.

Though many curing methods have been used over the years, the goal is always the same: to remove bacteria for long-term storage.

This is done to meats using preservatives like salts, sugars and nitrites, but when it comes to cannabis, we rely on nothing more than patience and persistence.

Benefits to Properly Curing Cannabis

Though every vegetable requires a different curing process for the best outcome, the goal is the same: to preserve the product while retaining vital flavors, nutrients and in the case of cannabis, cannabinoids.

Proper curing stops the degradation process before volatile compounds like terpenes and cannabinoids evaporate or transform into less favorable compounds.

From the moment the crop is harvested it begins to degrade as enzymes and aerobic bacteria break down excess sugars and starches. Curing cannabis essentially forces the plant to use up those sugars, starches and excessive nutrients before they’ve had the chance to dry out and get stuck inside the plant.

If you’ve ever wondered why some cannabis is harsher or less flavorful when you smoke it, it is because these residual components have not been properly cured out of the plant prior to drying and/or distribution to the consumer. A good cannabis cure will not only improve the flavor and smoothness of a smoke sesh, it will also improve product potency, too!

That’s because cannabinoid synthesis (the process of creating those valuable chemicals) continues even after harvest.

When freshly-harvested cannabis flowers are kept at the proper temperature and humidity, non-psychoactive cannabinoids will continue to transform into THCa, a precursor to psychoactive THC.

How to Cure Cannabis

To effectively cure your harvested cannabis (if you’re unsure when to harvest, click here), begin by hanging trimmed bud upside down in a dark room from a laundry line or clothing hangers. Buds that are still attached to the stock will hang easily at the node while smaller, “popcorn” buds may need to be dried on a screen to encourage airflow.

The room should ideally be kept between 60 and 70 degrees Fahrenheit with a humidity level between 45 and 55 percent to help preserve the terpene content of the bud.

After one to two weeks, the stems should gently break when bent (instead of folding like they do when they’re fresh) and the outside of the flower should be slightly crisp. When this happens, it’s time for the next step: sweating your bud. You’ll do this by removing the bud from the larger stems (use this time to finish manicuring them if necessary) and placing them in sealable containers.

Set the containers in a cool, dark location then return multiple times daily to open (or “burp”) the containers which removes excess moisture by drawing it out through the bud slowly while keeping the oxygen content fresh.

Note: if you notice the smell of mold or ammonia after burping your containers the first few times, it likely means the bud is not dry enough to cure yet. Remove the buds from the jars and continue air-drying for a few more days to avoid mold.

After a few weeks, you’ll be able to burp your containers less frequently (once every few days to a week, for example) while the bud continues curing. Though your bud will be fine to smoke after two to four weeks, continued curing for four to eight weeks or more will improve the flavor and potency even more. Properly cured cannabis can be stored for up to six months in these containers or for long-term storage, it can be kept in vacuum-sealed storage for a year or more.

Final Thoughts

You don’t have to be an experienced cannabis cultivator to produce high-quality bud at home. Ideal strain and grow conditions aside, the best bud always takes a bit more love and attention, and the curing process is no exception.

Taking the time to properly cure your cannabis will pay off big-time, and earn you some awesome bragging rights, to boot.

    As the American cannabis marketplace gets legitimized, business procedures concerning the cultivation, processing, and storage of marijuana flowers are a reflection of an industry transformation into the mainstream. With this in mind, cannabis business models—mainly in the cultivation sector—are adopting procedures based on efficiency and industrial production.

    The roots of the American cannabis marketplace are found in the underground expanses of western states such as California, which has had a functioning medical marijuana industry for over 20 years. Artisanal growers in these arenas oftentimes paid careful attention to the fine details of cannabis cultivation, processing, and storage. They also took great pride in properly drying and curing their flowers.

    Looking at industrial agricultural models of regulated cannabis cultivation seen in states like Colorado, much of the intimate care of artisanal farming — including proper drying and curing processes — is lost in favor of efficiency and subsequent cost reduction. While it is commonly known that improper curing techniques can greatly hinder the flavor and smell of cannabis, little has been said about any potential health issues related to smoking uncured flowers.

    Here are a few interesting points to consider concerning the relationship between human health and properly drying and curing buds:

    Curing And Drying

    Proper drying and curing procedures are essential in producing the highest quality, as well as healthiest to consume, marijuana flowers.

    As per drying, experts recommend that flowers are dried in a dark room with low humidity and temperatures around 75 deg. F. Once flowers are almost completely dry, yet a bit “springy” to the touch, they are ready for curing. While this process may not seem too difficult, one would be amazed at how many growers nearly destroy their products by over-drying or under-drying their flowers.

    While explaining the fine nuances of the curing process is beyond the scope of this work, there are a couple of important points to note in the relationship between curing processes and health issues surrounding marijuana smoking. According to renowned marijuana authority Kyle Kushman, curing cannabis flowers causes “aerobic bacteria to come to life. They will consume chlorophyll and make your buds smoke … less harsh on the throat.”

    When marijuana flowers are properly dried and cured, these processes make for the healthiest flowers to consume. Smoking fresh or improperly cured buds can not only lead to a sore throat for users—due to water and chlorophyll levels in the plant—but can also cause chronic lung problems with incessant coughing. For asthmatic cannabis users, this notion is greatly heightened.

    CBG And THC

    The marijuana plant harbors a number of chemical compounds which, altogether, present a vast array of potential medical applications for human beings. However, how these chemical compounds express themselves varies with the life-cycles of the plants, even after harvest. For example, the cannabinoid CBG, or “cannabigerol,” actually acts as the precursor chemical compound to THC.

    Studies have shown that CBG continues to break down into THC for a good amount of time after the plant is harvested—this chemical process is promoted by proper curing practices. As such, thorough curing practice ensures that cannabis flowers “express” their THC levels to their maximum capacity. Therefore, properly cured cannabis flowers present an attractive medicine for those medical marijuana patients whose ailments respond favorably to THC.
