B+ Psilocybe Cubensis

B+ is a strain of the Psilocybe cubensis mushroom that is famous world wide 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 come from this well domesticated Strain. B+ remains one of the all time champions of the Psilocybe cubensis world.

It is claimed that B+ cubensis can grow in wide range of temperatures, all the way down to 40 degrees Fahrenheit. While we arent so sure of this, it is an interesting claim. We do know that it is a very adaptable strain, growing on pretty much anything you throw at it, from brown rice flour, compost, and even wood chips. There is no question that this is must have strain for any serious collector, and is great for a beginner, as this strain also appears to be highly contamination resistant in its spore syringe.

Miscellaneous facts

  • Colonization times are average
  • Robust rhizomorphic mycelium
  • Makes huge and dark spore prints
