McKennaii Magic Mushrooms (Psilocybe Cubensis)

McKennaii magic mushrooms are a strain of Psilocybe cubensis, one of the most commonly used species of psilocybin mushroom. The latter is a medium-strength magic mushroom, whereas McKennaii mushrooms — like many other strains of Psilocybe cubensis — are very potent. This means that they contain higher concentrations of the compounds psilocybin and psilocin, which are responsible for psychedelic effects.

McKennaii magic mushrooms get their name from the psychonaut, lecturer, author, and psilocybin enthusiast Terence McKenna. Several of his books explored different aspects of psilocybin mushrooms, as well as his own mushroom experiences and interpretations of them, such as The Invisible Landscape (1975), True Hallucinations (1989), The Archaic Revival (1991), and Food of the Gods (1992).

McKenna was known to discuss and recommend the high dose psilocybin experience in many of his talks, so perhaps it’s fitting that a potent type of magic mushroom would be named after him. This strain of Psilocybe cubensis is much sought after for its potency. This makes it one of the most potent magic mushrooms.

In this guide on McKennaii magic mushrooms, we will explore various aspects of these mushrooms, including:

• How to identify McKennaii magic mushrooms
• How to grow Psilocybe cubensis (McKennaii) mushrooms, as well as where to obtain spores
• McKennaii mushrooms potency
• McKennaii mushrooms dosage
• The effects of McKennaii mushrooms

We have to emphasize that you should be aware of the law surrounding psilocybin mushrooms where you live, as mushrooms containing this psychedelic compound are illegal in most countries around the world. If you want to grow and possess McKennaii mushrooms, you need to be aware of the legal risks involved.

Identifying McKennaii Magic Mushrooms

McKennaii magic mushrooms look similar to normal Psilocybe cubensis mushrooms, with distinctive features such as a deep brown (for young ones) to light brown (for mature ones) colored cap, as well as a distinctive dark brown color in the center of the cap. The caps of both of these mushrooms are also larger compared to other species of shrooms.

In addition, McKennaii magic mushrooms and Psilocybe cubensis share a fairly thick, dense stem (stipe), which contrasts with the thinner stems of Psilocybe semilanceata (liberty caps), for instance.

However, a crucial difference between the two is that Psilocybe cubensis McKennaii magic mushrooms do not grow in the wild, as Psilocybe cubensis do. McKennaii magic mushrooms have been artificially bred to have higher concentrations of psychedelic compounds. So, if you encounter mushrooms in the wild that have the appearance of Psilocybe cubensis, they won’t be McKennaii magic mushrooms, nor will they be another artificially bred strain.

But what if you purchase mushrooms from someone and they look like Psilocybe cubensis? How would you be able to tell whether they’re McKennaii magic mushrooms or some other strain?

This may be difficult.

Some strains do have a distinctive appearance, such as penis envy mushrooms (as the name suggests, they’re phallic-shaped). But distinguishing between the McKennaii strain and normal Psilcoybe cubensis mushrooms would not be as easy.

This is why it’s better, for your peace of mind, to source Psilocybe cubensis McKennaii spores from a high-quality, trusted vendor, and then grow them yourself. This will give you the assurance that you have the type of psilocybin mushroom you want. Even if a street dealer or dark vendor advertises their product as McKennaii magic mushrooms, this is no guarantee that they will in fact be those mushrooms.

How To Grow Psilocybe Cubensis McKennaii Mushrooms

Growing McKennaii magic mushrooms involves the same process as growing other varieties of Psilocybe cubensis. You should refer to our guide on how to grow psilocybin mushrooms at home for detailed instructions. But let’s now offer a quick summary of everything you need and the steps you should take.

Psilocybe Cubensis Spores

First, you need to source some Psilocybe cubensis McKennaii spores. These are the reproductive cells that allow the mushroom to grow. Magic mushroom spores do not contain psilocybin, so they are not themselves illegal. But once they germinate and begin producing mycelium, psilocybin will be produced, making the end product illegal (since psilocybin is a controlled substance in most countries).

Magic mushroom spores are, however, illegal in California, Georgia, and Idaho. In the other 47 states, you’re free to buy and possess them.

There are different ways to procure Psilocybe cubensis spores, whether they be of the McKennaii variety or any other variety.

The most popular option is to buy them online from a vendor selling a spore syringe or print. The spore syringe is an oral syringe that contains just water and the wavy cap spores, while spore prints are little pieces of paper with the spores stamped onto them. The prints are dried and need to be rehydrated when you want to use them.

Steps For Growing McKennaii Mushrooms

It’s best to use our detailed guide for following the steps for growing wavy caps. You need the right ingredients, equipment, and hygiene supplies before getting started. The necessary steps will then be:

• Preparing the jars
• Inoculation
• Colonization
• Preparing the grow chamber
• Fruiting
• Harvesting
• Drying the mushrooms for long-term storage (Psilocybe cubensis dried will still be as potent for around a year, whereas if fresh, they will only stay good in the fridge for 5-10 days)

Purchasing a Psilocybe Cubensis Grow Kit

There are many reputable online vendors selling McKennaii mushroom grow kits. Magic mushroom grow kits are 100 percent legal for vendors to sell — and for you to buy — in the United States, except in California, Idaho, and Georgia (since, as we have highlighted, the spores are illegal in these states). This kit from The Third Wave is a great option.

McKennaii Mushroom Potency

To reiterate, McKennaii magic mushrooms are a highly potent type of magic mushroom, contrasting with Psilocybe cubensis, which is a medium strength mushroom. But exactly how potent are they?

Most Psilocybe cubensis grow kit websites, growers, and users state that McKennaii magic mushrooms are one of the most potent strains of Psilocybe cubensis. However, since this is a relatively new strain, data on its concentrations of psilocybin and psilocin are lacking, so we don’t know for certain precisely how potent this strain is.

McKennaii Mushrooms Dosage

As a general rule of thumb, you should consider McKennaii magic mushrooms to be stronger than Psilcoybe cubensis and adjust your dosage accordingly. You should take a lower dosage of them compared to less potent species of magic mushrooms (assuming you want a similar intensity of effects).

Erowid lists the following dosages for Psilocybe cubensis, a medium strength psilocybin mushroom:

• Light: 0.25-1 grams
• Common: 1-2.5 grams
• Strong: 2.5-5 grams
• Heavy: 5+ grams

With Erowid’s dosage recommendations for Psilocybe cubensis and people’s experiences with McKennaii magic mushrooms in mind, the following dosages for the latter can be used as a rough guide:

• Light: 0.15-0.75 grams
• Common: 0.75-1.5 grams
• Strong: 1.5-3 grams
• Heavy: 3+ grams

A Strong Dose Of McKennaii Magic Mushrooms Can Induce Mystical Effects

If you take a high dose of magic mushrooms, and potentially if you take a medium dose, you can experience mystical effects, which classically include:

• A feeling of unity (also known as oneness)
• Noetic quality: The feeling of gaining insightful knowledge, experienced at an intuitive level. You may have the sense of encountering ultimate reality
• A sense of sacredness or reverence
• Positive mood: Feelings of peace, tranquility, ecstasy, awe, or joy
• Transcendence of time and space: You may have the sense of being “outside time”, being in a realm with no spatial boundaries, or existing in a timeless state
• Ineffability: The feeling that you cannot adequately describe the experience in words

Duration Of McKennaii Magic Mushrooms Effects

A McKennaii mushroom trip will generally last between 4-6 hours. This duration is pretty consistent. In clinical trials involving psilocybin, most sessions will last up to six hours. After this time, the participants will no longer experience any psychedelic effects.

But the duration of a psilocybin experience for any individual depends on a few factors:

• Dosage. Taking a low dose of magic mushrooms could result in a trip lasting only a few hours, whereas consuming a high dose could lead to a six-hour experience.
• Method of consumption. It takes around 30 minutes for shrooms to kick in. But you can quicken this process through lemon tekking — it is believed the citric acid in the lemon juice breaks down the mushroom material, saving your body some time it would otherwise spend breaking it down. The lemon tek method may result in a faster onset and a stronger and shorter journey than eating dried mushrooms as they are.
• Eating psilocybin mushrooms on an empty stomach can lead to a faster onset than consuming them on a full stomach.
• Cannabis may elongate a magic mushroom trip if you smoke it towards the end of the experience. This is because cannabis tends to potentiate the effects of psychedelics. Not everyone may experience this effect, however.

Psilocybin mushrooms have neither long-lasting nor short-lasting effects. Here is the duration of other psychedelics, so you can get a better sense of this:

• DMT: 5-30 minutes
• 5-MeO-DMT: 15-45 minutes
• LSD: 8-14 hours
• Mescaline: 8-16 hours
• Ibogaine: 8-24 hours

The duration of a mushroom trip is comparable to that of ayahuasca (also 4-6 hours). For many users, 4-6 hours of tripping is ideal; it means the experience is easier to fit into a day and less likely to interrupt sleep than, say, mescaline or LSD. But it is also not quick and short-lived like the DMT or 5-MeO-DMT experience, so there’s still plenty of time to digest what is happening.

You may also be wondering “How long does Psilocybe cubensis stay in your system?” Well, your body will typically clear psilocin from your system in about five hours, whereas it will take nearly three times longer (up to 15 hours) to clear psilocybin. The exact time it takes is different for everyone, but it’s unlikely there will be any traces of psychedelic compounds in your system after 24 hours.
