B+ 5x Concentrated Spore Syringe – 10cc | Spore Genetics

Maximum Spore Density. Clean Results. Built for Precision.

Our B+ 5x Concentrated Spore Syringe is packed with five times the spore density of a standard syringe—designed specifically for researchers performing high-resolution microscopy, agar plate work, and advanced isolation techniques. This premium Psilocybe cubensis strain, often referred to as B Positive Mushrooms or B Cubensis, is trusted for its versatility, resilience, and beginner-friendly performance.

Each 10cc concentrated spore syringe is prepared in our ISO-7 certified cleanroom using Bonsai Filtration laminar flow systems, ensuring contamination-free quality from the moment it leaves the lab. The dense concentration of B Plus spores ensures strong visuals under the microscope and allows you to stretch one syringe across multiple research plates or slides with consistent performance.

Known for producing large, golden-caramel caps and thick, white stems with dark gills, B+ spores offer striking visuals—especially under agar plate observation, where their rich purple-brown spore coloration stands out clearly. This strain thrives on grain spawn such as rye or 5-grain, and pairs well with bulk casing layers like equine dung or enriched soils, making it a favorite for studying the full cubensis lifecycle in varied research conditions.

Originally believed to have surfaced in Florida during the 1990s, B+ has since become one of the most studied and widely shared cubensis strains in microscopy and mycology circles.
