If you want to buy P. Cubensis B+ Spores, be cautious as B+ strain spores are “active spores” which are for microscopy or artistic purposes. We will not complete your order if you contact us regarding the cultivation of active spores. Similarly, for legal reasons if you mention cultivating active spores or ask for cultivating advice, you will be subsequently banned from the site.

These spores are from a species that produces psilocybin and psilocin. For legal reasons they can only ship to 47 out of the 50 United States. Shipping is unavailable to California, Idaho, and Georgia.

These spores and photos were acquired from outside, trusted sources in a legal manner.  Further, Sonoran Spores does not condone or participate in the cultivation of psilocybin/psilocin producing or “active” species.  Sonoran Spores also does not have any mycelium or fruiting bodies of psilocybin and psilocin producing species.  We will not sell any products containing this so do not ask.

Spore Visibility Disclaimer: When you buy B+ spores, visibility is dependent on the characteristics of the spores themselves. As a result, not all spore syringes will look the same visibly.  Some may have some black clumps or specs in them and others may appear clear to the naked eye. Despite these visible differences, spore syringes are still made to be viable for microscopy research.

B+ Spores Information

B+ is another extremely popular Cubensis variety, and with good reason. The wild specimens of this strain found by researchers are some of the biggest Cubensis ever recorded. B+ was first found growing wildly in Florida back in the 1990’s. The first specimen found was a shocking 16 inches (40cm) long! That is definitely much larger than the average Cubensis, especially in the wild. Few varieties can exceed 16 inches.

Once the genetics hit the market they were an instant hit and their demand soared. B+ spores have always been one of our most popular products, second only to Golden Teachers. Because of B+’s large size, and the fact that it is also documented to be highly cold resistant, makes it a popular choice for all spore collectors. Especially beginners!

We strive to provide you with the cleanest possible products. We make all of the B+ spore syringe solution in front of Laminar Flow Hoods with HEPA filters. These HEPA filters have an efficiency rating of 99.97%. Meaning that the filter removes 99.97% of particles in the air. To make the actual spore solution, we take clean spores and mix them with sterile distilled water. Then, a magnetic stirrer properly mixes the solution to ensure an even distribution of spores throughout the solution.
