The B+ strain of Psilocybe cubensis is one of the most popular and widely cultivated psychedelic mushrooms today. It was introduced in the 1990s by a mysterious cultivator known as Mr. G, who promoted it as a resilient, high-yielding variety suitable for beginners.
The name B+ is rumored to have originated from its impressive size and strong performance, as well as the “be positive” experience it tends to provide. This strain is known for its moderate to strong potency, often producing euphoric, introspective, and visually immersive trips with a warm, uplifting body high. B+ has remained a favorite among cultivators and psychonauts alike due to its hardy nature, ability to grow in a variety of conditions, and balanced psychedelic effects that make it ideal for both beginners and experienced users alike.
