B+ Spore Syringe – 10cc | Spore Genetics
Also known as B Plus Mushrooms, B Positive, or B Cubensis
The B+ Spores Syringe remains one of the most popular Psilocybe cubensis strains in the world—well-known for its resilience, large fruit size, and ease of cultivation. Whether you're just starting your microscopy journey or exploring advanced techniques, B Plus spores are widely regarded as among the most beginner-friendly options available.
Each syringe contains a thick density of millions of B+ spores, suspended in sterile solution and prepared in our ISO-7 cleanroom to ensure zero contamination. These spores are ideal for microscopy, genetic observation, and taxonomy studies, offering consistent results and impressive spore structure under the microscope.
B+ mushrooms are known to produce thick, uniform stems and large caps that range in color from deep reddish-brown to golden caramel. The caps often appear glossy or slightly sticky in texture, especially in high-humidity environments. Under the microscope, their dark purplish-brown spores and nearly black gills at maturity offer excellent contrast for detailed visual study.
This strain adapts well to a range of environmental conditions, thriving best on nutrient-rich substrates like equine dung and enriched soils, especially when paired with a subtropical temperature range. While optimal conditions yield especially large flushes, B+ is also known to perform reliably even in less-than-ideal environments, earning its reputation as one of the most robust strains found in nature.
Believed to have originated in Florida, B+ Cubensis has demonstrated high resistance to contaminants and consistently vigorous growth, making it an excellent choice for both field collection and lab research.
