Growkit Store – research mycelium kits
In this section you will find growkits with fully developed mycelium, intended for microscopy, taxonomy and mycology education. They allow you to study well-known Psilocybe cubensis strains such as Golden Teacher, Mazatapec or McKennaii in a compact, ready-to-use form.
A growkit is legal to possess in Poland because the mycelium does not contain prohibited substances. However, cultivating psilocybin mushrooms and possessing fruiting bodies is illegal. Always check the current legal status in your country before ordering.
Shipments with growkits are sent Monday–Thursday; international orders are usually dispatched on Mondays to keep the cold chain as short as possible. For correct storage and handling see: how to store a growkit.

What is a growkit?
A growkit is a compact research set containing a fully colonised mycelium block placed inside a protective box or filter bag. In mushroom growkits the block is colonised by a specific Psilocybe cubensis lineage, which makes it suitable for microscopy, taxonomic work and educational mycology. Growkits are legal to possess in Poland because the mycelium itself does not contain psilocybin – however letting it produce fruiting bodies is prohibited. For a broader overview of the species see Psilocybe cubensis and our article what is a growkit.

Each growkit typically contains:
- a mycelium block of a selected Psilocybe cubensis variety,
- a breathable bag with air filters,
- paper clips for closing the bag,
- protective cardboard packaging for safe transport.
Growkit Golden Teacher
Growkit Golden Teacher is one of the most popular research specimens in our offer, recognised for its broad golden caps and thick, stable stems. It is available in both 250 ml and 1200 ml versions, so you can choose the volume that best fits your microscopy or educational project. More details on construction and substrate composition can be found in the article: what is a growkit made of.

Growkit shelf life and storage
Growkits have a limited shelf life. When stored in a refrigerator at 2–4 °C, the mycelium usually maintains good quality for up to around six months. Our store receives fresh deliveries every week, which allows us to keep regular rotation and long remaining best-before dates.
For the best research results, we recommend starting microscopy or laboratory analysis shortly after receiving your parcel. Practical tips can be found in the guide: how to store a growkit.

Product freshness & legal information
We carefully monitor temperature and storage conditions so that every kit leaves our cold room in optimal state. Growkits are sold exclusively for research, microscopy and collector purposes. Owning a mycelium block is legal in Poland, but allowing it to produce mushrooms that contain psilocybin is not.
Before ordering from abroad, always verify the current law in your country. In our theoretical growkit guide you will find information on what to avoid to stay compliant with local regulations.
Growbox – mushroom varieties available
All growkits offered in our store are shipped from Poland, which ensures fast delivery and high freshness. We stock a wide selection of Psilocybe cubensis strains for research:
