B+ is a strain of the Psilocybe cubensis mushroom that is famous worldwide for its size. It was found growing wild in Florida in 1999, in a place where cow manure used to be, and its original spore prints were distributed to other spore vendors and cultivators.
This mushroom gets HUGE, in the wild. Some of the mushrooms that have been observed by B+ cubensis have been over 16 inches tall!
Very few strains can get this large, with the exception of Alacabenzi, Amazonian, and a few others. It is also one of the original few that have been cultivated for more than 40 years now, which guarantees no one will be disappointed with the genetics that comes from this well-domesticated Strain.
B+ remains one of the all-time champions of the Psilocybe cubensis world.
