This B+ XL mushroom kit is an improved mushroom kit with 80% more substrate than our medium sized mushroom kits. The B+ is probably the best known (mexican) strain and is in our top 3 best selling strains.
This XL mushroom box contains the mycelium of the Psilocybe cubensis ‘B+’ strain. The B+ mycelium is colonized on a substrate of rye and perlite. The top layer is covered with vermiculite.
