Z-Strain Magic Mushrooms, sometimes called “Z-Cube,” is an average potency magic mushroom strain with uniquely aggressive growth characteristics. It’s an excellent strain for the hobby cultivator.

This strain has been found to have roughly average potency on several occasions, but online trip reports would have you think otherwise. It’s often renowned for having especially strong physical effects. Some users report intense tactile sensations — often described as a “gentle buzzing” of the skin.

What makes this strain so special is its affinity for producing rhizomorphic mycelial growth. This refers to a particular growth pattern involving thick “threads” of mycelium that spread quickly through the mycelium. This is in opposition to the tomentose growth pattern, which is much more fluffy in appearance and slow-growing.

In general, the string-like rhizomorphic mycelium is viewed as more resistant to disease, faster growing, and produces dense flushes of potent mushrooms later on during the fruiting stage.

All strains can produce both rhizomorphic and tomentose mycelium, but the Z-strain appears to be a genetic isolation of a strain that (almost) always produces the superior rhizomorphic form.

History of Z-Strain Magic Mushrooms

Z-Strain belongs to the Psilocybe cubensis family of psychedelic mushrooms. The history of this mushroom is unclear (and somewhat controversial) — but this isn’t unique to this strain. Many mushroom strains are born from underground cultivation by unknown hobbyists and expert mycologists. Because magic mushrooms are illegal, few people have stepped forward to take public credit for their creations.

The Z-strain is no exception, but there are a few theories floating around about its possible origins.

Some reports suggest this strain was created by the legendary mycologist Paul Stamets, but he’s never publicly accepted credit for this unique mushroom.

There’s another story about a mysterious mycologist named “The Keeper,” who claims to be responsible for cultivating this strain.

The controversy is that The Keeper would take established mushroom strains, rename them, and sell them online as their invented strain through ads in High Times magazine and online.

According to a Reddit thread, The Keeper was caught when they used photos of established strains and forgot to change the names of the files when uploading them online under their new strain name.

Others believe this strain came straight out of stock and developed by the legendary mycologist Paul Stamets.

Regardless, the consensus on the origin of the Z-Strain mushroom is that it’s an isolation of the famous Golden Teacher strain, which hails from Mexico, but this hasn’t been confirmed.

Z-Strain Magic Mushrooms Potency & Psilocybin Content

Oakland Hyphae hosts a yearly Psychedelic Conference and The Psilocybin Cup, in which cultivators from around the world submit their mushroom strains to compete for the most potent shroom.

In the Spring Oakland Cup 2021, a Z-Strain sample submitted by No Cap was graded “A.” The sample strain had a psilocybin content (PCB) of 0.66% and a psilocin content (PCN) of 0.17%. The total tryptamine level was listed as 0.83%.

While these figures certainly aren’t the highest on this list, we only have one sample to go off. It’s likely that under the right conditions, the Z-strain is capable of much higher potency levels.

We consider the average range for Psilocybe cubensis mushrooms to fall somewhere between 0.5% and 0.9% total tryptamines (dried weight).

Other samples have been found to contain as much as 2% psilocybin and 1.2% psilocin — which would place it in the very potent category. Unfortunately, the official lab reports for these findings have not been made public so we’re unable to confirm these figures.

Comparing Z-Strain to a popular shroom stain and Z-strain’s presumed relative, Golden Teacher, we can see that they’re relatively similar. However, Golden Teachers have a slightly lower psilocybin and psilocin content of 0.73% (based on 11 separate Psilocybin Cup entries across 2 years).

These strain entries were submitted by experienced growers, who we can presume provided the best growing conditions for their mushrooms.

Z-Strain Magic Mushrooms Variations & Genetic Relatives

The closest relative to Z-Strain is the Golden Teacher mushrooms, perhaps the market’s most dominant variety of shrooms.

Z-strains and Golden Teachers share distinctive yellow-gold caps, which is just one of the many reasons many people believe that Z-Strain is an isolation of this shroom.

Golden Teachers are known as dependable shrooms for their gentle entheogenic effects and easy cultivation.

You can find Golden Teachers and other variants of this strain at virtually any major spore vendor online, and it’s a reasonably beginner-friendly spore to start with.

Other relatives of the Golden Teacher strain include:

• Albino Penis Envy
• Alcabenzi
• Golden Emperor
• Golden Halo
• True Albino Teacher
• White Rabbit
• Yeti

How to Grow Z-Strain Magic Mushrooms

A wide variety of Psilocybe cubensis grow naturally in the wild, but Z-Strain is not one of them.

To get a shroom like Z-Strain, mycologists will selectively breed strains in a lab to pass on specific characteristics such as their potencies, life cycles, resistance to contamination, and large fruiting yields.

Z-Strain is often sold as a great beginner strain as the mycelium tends to aggressively colonize its substrate, is relatively resistant to contaminants, and yields impressive flushes of mushrooms in a short amount of time.

To grow Z-Strain shrooms, you’ll need to find spores and a grow kit, which you can DIY if you’re up for it.

Z-strain’s ability to form rhizomorphic mycelium without much intervention makes it one of the easier strains to cultivate. Most strains will produce rhizomorphic and tomentose mycelium, but rhizomorphic growth is considered the best for cultivators. It grows faster and offers better contamination resistance. These effects lead to more abundance and higher potency.

Many growers will germinate their spores in agar plates to isolate the rhizomorphic patterns. They then cut sections of the rhizomorphic mycelium from the agar and use that to innoculate their substrate jars.

Despite having a somewhat higher contamination resistance, growers must ensure their workstations and equipment are sterile to avoid botching the process.

The ideal temperature for Z-Strain is around 24°C (75°F), and you want to keep your fruiting chamber humid.

You can pick the fruit from the stems once the caps open and leave them dry. Don’t throw away your substrate cake just yet — you can expect multiple flushes from these shrooms by maintaining the temperature and humidity. With each flush, the yield will become sparser and sparser.
