Pre-Sterilized B+ Cubensis Spore Syringe for Microscopy
B+ is a very popular Cubensis variety that was originally commercialized by Mr. G between the late 80s and early 90s. His company was falsly claiming that B+ was a hybrid of Cubensis and Azurescens. While many pronounce the variety name as “B-Plus,” some insist that the variety is called “Be Positive.” B+ spores appear dark with a purplish hue, and its fruits grow up to have a beautiful cap that turns dark red to golden brown color. This variety has been highly domesticated over the years to be very stable, making it a very good choice for all researchers whether they are a beginner or expert.
