Psilocybe cubensis cultivars: know before you grow

All of these are cultivars of Psilocybe cubensis, the species most cultivated by beginners. Educational characteristics only: difficulty, colonisation speed, relative potency and notes. A field guide, not a shopping list.

Golden Teacher (GT)

Difficulty 1/5 · Colonisation: Medium · Relative potency: Moderate · beginner, reliable

The classic teaching cultivar. Forgiving, consistent, golden caps. If it is your first grow, it is probably this. Slower than some, but rarely dramatic.

B+ (Be Positive)

Difficulty 1/5 · Colonisation: Fast · Relative potency: Moderate · beginner, large fruit

Enormous, forgiving fruits and a wide tolerance for less-than-perfect conditions. A beginner favourite for exactly that reason.

Cambodian

Difficulty 1/5 · Colonisation: Very fast · Relative potency: Moderate · beginner, fast

A rocket. Colonizes aggressively enough to outrun a lot of beginner mistakes, which is why experienced growers recommend it for a confidence-building first run.

Mazatapec

Difficulty 2/5 · Colonisation: Medium · Relative potency: Moderate · traditional

A traditional lineage with deep cultural roots in Mexico. A little more sensitive to conditions than the true beginner strains, and worth it for the history.

Albino A+ (AA+)

Difficulty 3/5 · Colonisation: Medium · Relative potency: High · leucistic, photogenic

Leucistic and pale, almost ghostly under the light. Photogenic and a touch fussier. Bruises a deep blue, which makes reading its health easy.

Blue Meanie

Difficulty 3/5 · Colonisation: Medium · Relative potency: High · heavy bruising

Heavy blue bruising and a reputation to match. Not to be confused with the Panaeolus of the same nickname. Intermediate hands only.

Z-Strain

Difficulty 2/5 · Colonisation: Very fast · Relative potency: Moderate · fast, rhizomorphic

An aggressive, rhizomorphic colonizer that races across grain. Fast to the point of impatience, which suits a grower who wants to see progress.

Penis Envy (PE)

Difficulty 5/5 · Colonisation: Slow · Relative potency: Very high · advanced, potent

Notoriously potent, notoriously slow, and emphatically not a beginner cultivar. Dense, low-sporing, temperamental. Included here as the thing to grow toward, not to start with. Treat its strength with respect.
