B+ Mushroom Strain: The Forgiving All-Rounder
The B+ mushroom strain is one of the most beloved varieties of Psilocybe cubensis ever cultivated. Renowned for its well-rounded effects, this magic mushroom delivers a pleasing fusion of cerebral and visual perceptions. Users frequently describe feeling euphoric and deeply connected to their surroundings, which makes the B+ a popular choice for contemplative meditation or relaxed outdoor walks. The visual effects — colours that seem more vivid, patterns that grow more prominent — are usually subtle yet enhancing, and the overall journey stays mild and uplifting rather than overwhelming.
Because the B+ strain is so gentle and forgiving, it suits both newcomers and seasoned psychonauts. It has become a true staple of the psychedelic community, celebrated for an accessible, enjoyable experience that rarely tips into intensity. If you want a dependable, balanced psilocybin mushroom, the B+ is hard to beat.
Origins of the B+ Cubensis Strain
The B+ cubensis strain originated in Florida in the late 1980s and became well known almost immediately thanks to its versatility and toughness. This psilocybe cubensis variety adapts readily to a wide range of temperatures and substrates, which is part of why it spread so quickly among growers. Its name, B+, is widely believed to reflect both its positive, beneficial effects and its above-average size. Despite somewhat mysterious origins, the B+ psilocybe strain has earned a permanent place in cultivation history.
As a classic psilocybin mushroom, the B+ shares the same genus as famous relatives like the Golden Teacher, yet it stands apart for its resilience. It fruits reliably, produces large caps, and tolerates beginner mistakes that would stall a fussier strain — one reason it consistently appears on every short list of starter cubensis varieties.
Potency & The Psychedelic Experience
In terms of strength, the B+ sits in the moderate range for a psychedelic cubensis — potent enough to deliver a genuine psychedelic journey, gentle enough to stay comfortable. The active compounds, psilocybin and psilocin, convert in the body to produce shifts in mood, perception, and thought. Levels of psilocybin and psilocin in the dried mushroom vary with growing technique, but the B+ reliably lands in a balanced, approachable band of psilocybin potency. A measured dose can heighten the senses and open the door to introspection without the disorienting edge that more aggressive psychedelic strains can bring.
This is also why the B+ shows up so often in modern psychedelic science. As clinical trials continue to explore psilocybin for mood, anxiety, and treatment-resistant depression, well-characterized cubensis strains like this one remain a useful reference point. We make no medical claims — but the research interest speaks to why this humble psilocybin mushroom endures.
Because every body responds differently to a magic mushroom, the golden rule still applies: start low and go slow. Set and setting shape the entire arc of any psilocybin experience, so choose a calm environment and give each dose time to unfold before considering more.
Growing B+ from Spores
The B+ is famous for being one of the easiest strains to grow, which is why it is so often recommended to first-time cultivators and microscopy hobbyists alike. Cultivation typically begins with a spore print or, more conveniently, a spore syringe — a sterile suspension of B+ spores in water that can be used to inoculate a prepared substrate. Many growers find the B+ remarkably tolerant of variable conditions, colonizing quickly and fruiting generously across multiple flushes.
- Spore source: Begin with a clean B+ syringe or print sold strictly for microscopy and identification research.
- Substrate: The B+ thrives on common substrates, from grain spawn to manure-based mixes, making it ideal for the monotub method.
- Fruit: Expect dense, meaty fruit bodies with broad caps and sturdy stipes once colonization is complete.
- Yield: Generous flushes and forgiving genetics make this one of the most rewarding strains for a beginning mycologist.
This ease of cultivation, combined with strong resistance to contamination, is exactly why the B+ remains a textbook choice in mycology. Whether you are a curious mycologist studying spores under the microscope or simply fascinated by fungi, the B+ offers a dependable, well-documented path from spore to mature mushroom.
Why Growers & Psychonauts Love B+
Few cubensis varieties manage to be this versatile. The B+ mushroom is resilient in the grow tent, balanced in its effects, and welcoming to beginners — a rare trifecta. It belongs in the same conversation as other premium psilocybin mushrooms, yet earns its lasting popularity through sheer reliability. For the cultivator who wants consistent results and the explorer who wants a smooth, uplifting psychedelic experience, the B+ delivers on both counts.

I reeeaaally wanted to love this strain. After much research and decision making I finally settled on this one and was looking forward to trying it— and I did.
I tried it on 3 separate occasions. Same conditions each time, same physical/mental state. I’m not a novice tripper. There was nothing in my arrangement that I felt contributed to the terrible experience.
I hated these. I’ve tried different strains and while some weren’t great, I have never disliked another strain as much as I dislike this one.
They made me feel irritable, agitated, short tempered and overall just annoyed by the smallest things such as the flicker of a flame on a candle.
My temper went from 0-100 on these in an instant at the slightest inconvenience. It was something else.
The most similar thing I can equate it to is the state of annoyance cats find themselves in when they start swooshing their tails and making airplane ears.
The first time I thought it was a one off.
The second time I thought it was a crappy coincidence.
The third time was confirmation.
This strain brings out some kind of weird, unexpected anger and agitation in me. Nothing that wasn’t manageable, but it wasn’t pleasant and not how I wanted to enjoy my mushrooms.
I did not like this strain and would not repurchase but I do hope that anyone else purchasing it will have a more pleasant experience than I did. My rating reflects my experience overall.
Otherwise, shipping/delivery/etc, customer service is always great with this company. Love these guys.
Good luck to anyone who decides to try B+.
