Argentina is a well-known strain of magic mushroom. You’ll find Argentina spores on just about every major spore vendor around the world at this point. This strain is best known for how easy it is to grow and for its exceptionally long-lasting harvest cycles. While not everyone will be so lucky, there are numerous reports of mushroom growers harvesting in flushes reaching into the double digits. They just keep going! These shrooms have an average potency and provide relatively mild visuals and a much deeper body trip than many other strains. In this guide, you’ll learn all you need to know about Argentinian magic mushrooms, including what they look like, their potency, the effects they produce after consumption, how to grow them, and much more. What Are Argentina Shrooms? Argentina shrooms are a strain of magic mushroom belonging to the most common psychedelic mushroom genus and species: Psilocybe cubensis. Like other strains belonging to this species, Argentina shrooms contain psilocin and psilocybin. Psilocybin is metabolized in the human body and broken down into psilocin, which is a highly psychoactive chemical that gives magic mushrooms their psychedelic effects. As the name suggests, Argentina shrooms originated in Argentina, specifically in the mountainous rainforests around Tafi del Valle in Northern Argentina. The original sample is thought to have been collected in the late 1950s or early 1960s — making this one of the oldest strains on the market today. Argentina shrooms thrive in particularly moist, warm climates in the summer months. Most growers find that they do well in indoor growing conditions with consistent humidity and temperature controls. They do particularly well with a quick dunk in cold water (10–20 minutes) between flushes to keep them well hydrated.

Specifically, the spore sample was taken from Tafi del Valle, a city whose name roughly translates to “town in the valley with a splendid entrance.” Unfortunately, there is no information available as to who first identified and isolated this strain of magic mushroom. This species of magic mushroom belongs to the section — a taxonomic label that lies below genus but above species — of zapotecorum. Many other shroom species that are native to South America belong to this section. Argentina Shrooms Potency & Psilocybin Content The potency of a magic mushroom strain refers specifically to the psilocybin and psilocin content by dry weight of a fruiting body (a physical mushroom). These levels can vary wildly from sample to sample within a strain, so the potency of most shrooms is a rough estimate. The levels of these psychedelic chemicals also vary between species, although inter-species differences tend to be far greater. Some estimates for Argentina shrooms come in between 0.25% and 0.75% of psilocybin by weight, while significantly higher estimates suggest the potency of psilocybin and psilocin combined could reach up to 2%. For comparison, the average shroom belonging to the species Psilocybe cubensis has a combined psilocybin and psilocin potency of around 1.2% by dried weight. Generally speaking, it’s a better idea to compare the potency of different shroom strains based on overall user experience, primarily because the estimates can be quite far off, and the potency can range so much. Most people who take Argentina shrooms report an average level of psychedelic experiences. Most state that the trip comes with pleasurable visuals that aren’t too intense, as well as a deep sense of connection with the world. As such, this is a popular strain for exploring one’s spirituality while maintaining a calm mind and a moderate sense of euphoria. The Oakland Hyphae2021 Psilocybin Cup didn’t see any entries from the Argentina strain. This could be due to a general lack of strain popularity, as it’s a somewhat common variant. Where to Buy Argentina Spores Argentina shrooms spores are fairly widely available. It’s likely that their popularity is due to their aggressive fruiting, which can produce up to or more than about 10 flushes. Although the size of the mushrooms is nothing special, the abundance with which they are able to be harvested makes them a popular magic mushroom strain to grow. There are several reliable sources you can turn to if you’re looking for Agentia shroom spores. If you live in the United States, you can check out Ralphsters Spores and Lil Shop of Spores, both of which commonly carry these spores. Other options include Spores 101 and FreeSpores. If you live in Canada, your best options are likely Sporeslab and Spore Door, although neither were actively carrying this strain at the time of writing. Similarly, you might have some difficulty finding these spores in Europe, although we recommend looking at The Magic Mushrooms Shop and Viking Spore first, as these are both reliable sources for spores.

How to Grow Argentina Shrooms Argentina shrooms are relatively resistant to mold and disease, and they are abundant fruiters that can provide up to around 10 flushes. As such, they’re considered an easy strain to cultivate, which makes them ideal for beginners. The process of growing these shrooms is similar to that of other strains, which we’ll detail briefly below. You can check out our in-depth guide on shroom cultivation for more information. Step 1: Prepare Your Substrate Shroom spores need a substrate to colonize and fruit. For Argentina shrooms, you can mix 2 parts brown rice flour, 2 parts vermiculite, and 1 part water to use as a substrate. You can use rye grain instead of brown rice flour if you prefer. Fill a mason jar up to around 3cm under the rim with this mixture, then top off with vermiculite. Step 2: Sterilize Your Substrate Put your mason jar lid on upside down (this helps prevent it from getting sealed shut later on), or seal it with tinfoil rather than the top. Place the jar in a pressure cooker and bring it up to just over 121 degrees F for at least 30 minutes. Step 3: Inoculation Next, sterilize the room you’re using for inoculation. Be sure to wipe down all surfaces with rubbing alcohol and let them dry fully before continuing. Any errors here can leave you with a contaminated shroom colony. Once you’re certain the room is sterilized, introduce your spore sample to the substrate. Step 4: Incubate Your Spores Keep your jar between 70 and 80 degrees F and at least 85% humidity. Make sure the jar isn’t exposed to direct or indirect sunlight. You’ll notice that the mycelium — a white, stringy substance — begins to overtake the substrate. Once all of the substrate is covered in mycelium, you can move on to the next step. Step 5: Fruiting Finally, your shrooms are ready to produce fruiting bodies. At this point, they will be far more resistant to mold and disease. Maintain the 85% humidity, but reduce the temperature to between 50 and 65 degrees. Step 6: Harvest Once the veil on the bottom side of the fruiting bodies starts to break, your shrooms are ready to harvest. Argentina shrooms provide multiple flushes, sometimes around 10 or more, so be patient with this strain. You can dunk your shrooms in a bath of ice water for around 20 minutes if you aren’t getting multiple flushes.
