Golden Teacher XL Mycelium box (2100 ML)


This Golden Teacher XL-MyceliumBox is an enhanced Mycelium kit with 80% more substrate. The Golden Teacher is one of our strongest and most visual mushroom strains. This is not a strain for beginners!

This XL-MyceliumBox contains the mycelium of the Psilocybe cubensis 'Golden Teacher' strain. The Golden Teacher mycelium is colonized on a substrate of rye and perlite. The top layer is covered with vermiculite.

Holding the double of the substrate, meaning the double of the expected Golden Teacher yield, the XL-MyceliumBox is an enhanced product allowing the formation of exceptionally big Golden Teacher magic mushrooms in an exceptional short amount of time.

Made for the amateur mycologist, the Golden Teacher XL-MyceliumBox highly reduces the probability of contamination and it's simplicity of processes will allow you to better focus on the amazing formation of mushrooms bodies. Made with the strongest redefined strains, growing mushrooms was never easier and more reliable.


Because the kits are fresh they need to be set up right away.
