SV 13 is a rare and visually captivating strain of Psilocybe cubensis, distinguished by its pale, ghostlike appearance and exceptional potency. The “leucistic” trait refers to its partial loss of pigmentation, resulting in creamy white stems and caps with subtle golden or bluish hues — a visual signature that sets it apart from standard cubensis strains.

Bred from carefully selected genetics, SV 13 is known for producing dense, well-formed fruiting bodies with a high psilocybin content. When handled, the mushrooms bruise with deep blue coloration — a reliable indicator of their strength. Cultivators admire this strain for its vigorous growth and resilience, while psychonauts praise it for its consistently powerful effects.
