Psilocybe mexicana can be grown easily using the PF Tek or MMGG method with just a simple modification to the substrate.
There are two substrates which should work pretty well. The first uses:
- 1 part (by weight) soft grain rice.
- 2 parts (by weight) water.
The second uses:
- 1 part (by weight) rye grass seed.
- 3 parts (by weight) water.
Substitute either of these substrates for the brown rice flour/vermiculite substrate of the cubensis cultivation method and keep all
other parameters the same.
