Looking for a straightforward way to cultivate Psilocybe cubensis at home? The B+ Magic Mushroom Inject & Grow Kit brings together a pre-sterilised substrate and B+ liquid culture in one ready-to-use system. Inject, wait, and let the mycelium do the work.

What Is the B+ Inject & Grow Kit?

B+ is one of the most recognised strains within the Psilocybe cubensis species, valued by hobby growers for its stable genetics, steady colonisation and adaptability to varied conditions. This complete kit removes the complicated preparation steps: no mixing, no pressure cooker and no specialised equipment. You simply inject the included liquid culture into the sterilised substrate and let the mushroom mycelium colonise naturally, making it a practical choice for both newcomers and returning cultivators.

Substrate Composition

Each B+ mushroom grow kit contains a professionally prepared substrate blend of whole oat, vermiculite, perlite and gypsum, held at a moisture level of around 60–65%. An integrated injection port allows clean inoculation, while the filtered fruiting bag supports proper airflow throughout colonisation.

Included B+ Liquid Culture

Every kit includes 10 ml of B+ liquid culture produced under sterile laboratory conditions, prepared from classic and stable genetics known for consistent performance in home cultivation.
