PF Tek

PF Tek is the method of mushroom cultivation pioneered by Robert McPherson, aka Psylocybe Fanaticus. This technique (tek) utilizes brown rice flour and vermiculite, sterilized in half pint wide mouthed canning jars by boiling or pressure cooking, with a layer of dry vermiculite as a filter agent to keep out competing bacteria and fungus. The "PF jar", after sterilizing, is then injected with spores from a syringe, creating a one step procedure for reliably growing mushrooms indoors.
