Genetic Background:

PF Classic originates from the creative mind of Robert McPherson. Named after his pseudonym, Psilocybe Fanaticus, and synonymous with the revolutionary PF-Tek cultivation technique, this strain has been a favorite since its introduction in the early ’90s. Its genetics are crafted for compatibility with diverse cultivation methods, making it a versatile choice for growers.


While PF Classic is known for its moderate potency, with total tryptamine levels typically around 0.67%, it offers a gentle entry into the world of psychedelics. It’s perfect for those new to psilocybin mushrooms, providing a manageable yet profound experience.

Growth Characteristics:

PF Classic is celebrated for its straightforward cultivation requirements, making it ideal for beginners. The mushrooms grow quickly but mature slowly, allowing cultivators to harvest without the rush of rapid sporulation. This characteristic also means less mess and maintenance in the fruiting chamber.


This strain produces medium to large mushrooms with saucer-shaped, golden brown caps adorned with white, wart-like spots. The stems are thick, white, and wavy, creating an impressive visual display. PF Classic’s slow maturation process ensures that each specimen reaches its full aesthetic and psychedelic potential.

Historical Significance:

Introduced to the market by McPherson alongside the PF-Tek, PF Classic has a storied place in psychedelic history. It survived scrutiny and legal challenges, including the infamous raid on McPherson’s home in 2003, which marked the end of but not the legacy of PF Classic.

Legal Disclaimer:

PF Classic spores are intended only for microscopy and taxonomic purposes. Cultivation and possession of Psilocybe cubensis mushrooms are illegal in many jurisdictions. Ensure compliance with local laws and regulations before acquiring these spores.

Experience the Classic:

PF Classic is more than just a mushroom; it’s a piece of psychedelic history. Ideal for those starting their mycological journey or seasoned cultivators looking for a reliable strain for micro-dosing or mild psychedelic experiences, PF Classic offers a unique blend of historical significance and cultivation ease.
