Growkit B+

Growkit B+ is a growing kit containing mature mycelium. This growbox does not contain any illegal substances and is intended for research purposes only. We strongly advise against growing psilocybin mushrooms, as the substances contained in the mycelial fruits are illegal in Poland and many other countries. Buying growkit means confirming that it will not be used in an illegal manner. Please note that we are not responsible for non-compliance with these recommendations, i.e. use of growkit for non-laboratory purposes. Before making a purchase, we recommend that you check the applicable laws on growkits in your country.

Growkit B+, despite animosity over its origin, was the most widely purchased mushroom in the 1990s. This is due to its ease of breeding, high temperature resistance. There is evidence that it grew even at only 7 degrees Celcius. However, the optimal breeding temperature is 23-26 degrees. Its fruiting bodies are quite sizable and eagerly try to get out of the growing bag. The stems are flexible and strong, although not as spindly as with other Psilocybe cubensis.


Psilocybe Amplus


Variety B+ was brought to life in Florida by a mysterious man hiding under the name Mr. G. It is Psilocybe cubensis, but controversial to the extent that the originator of this variety himself claimed that he managed to combine Psilocybe cubensis and Psilocybe azurescens. However, by many mycologists, this is an impossible theory. This would be compared to a cross between a human and an ape, and the fruit would be a healthy offspring. The mystery of the genesis has still not been revealed.


In Poland, the cultivation of psilocybin mushrooms, including Ecuadorian growkit, is illegal, so we strongly discourage such cultivation. However, if you intend to grow mushrooms in a country where it is legal, we encourage you to learn more in our
article on growing magic mushrooms.
It is important to always follow the applicable laws!


B+ users praise these hallucinogenic mushrooms, not least because after ingesting them, nausea is said to be less than with other varieties, visual effects are moderate, and perceptual sensations are pleasant, warm, enveloping sensations. Recommended for first experiments.
