The Magic Truffle Jar offers a simple and accessible way to grow your own magic truffles. This grow jar is completely ready-to-use and specially developed for people who want to get acquainted with the cultivation process without technical knowledge. You don’t have to weigh or mix anything; if you take good care of the jar, the mycelium does the work by itself.
The TruffleJar is especially suitable for curious users who enjoy following the growing process closely and deciding for themselves when and how much to harvest.
The Magic Truffle Jar is a ready-to-use grow jar in which the mycelium automatically forms magic truffles under the right conditions.
The TruffleJar contains fully grown mushroom spawn of Psilocybe Mexicana. In the right conditions, this mycelium forms magic truffles (also called sclerotia) directly in the jar. Because everything is already prepared, this method of growing is accessible to both beginners and people with some experience.
The TruffleJar is ready for immediate use and does not need to be adjusted. The most important thing is that you provide a suitable environment and give the cultivation process time.
The mycelium will continue to grow in the jar by itself. By leaving the TruffleJar alone and following the instructions, a stable environment is created in which truffles can gradually develop.
For those who like to have a clear overview of all the steps, an extensive cultivation manual is available in PDF format.
