PF Tek Method Grow mushrooms

This method of mushroom cultivation is cheap and pretty straightforward, therefore, perfect for the newbie fungi farmer and experienced “fungiculturist” alike.  For this process, you’ll prepare your substrate of brown rice flour, vermiculite, and water, and divide it between sterile glass jars. This allows you to control humidity while introducing air to the substrate providing the perfect environment for the mycelium to grow. After you’ve prepared the jars and divided the substrate, you’ll then introduce the spores and wait for the mycelium to develop. After about 4-5 weeks, transfer your colonized substrates, or “cakes”, to a fruiting chamber where you’ll wait for your mushrooms to grow. Check out the full step by step process of the PK Tek Method including preparation, inoculation, and colonization.

Preparing the Grow Chamber

So at this point, you’ve discarded any contaminated materials and consolidated the jars of your successful mycelium. Now it’s time to prepare your fruiting chamber and begin the birth process of your “cakes” or colonized substrates.

Make a shotgun fruiting chamber

  • Take your plastic storage container and drill ¼-inch holes roughly two inches apart all over the sides, base, and lid. To avoid cracking, drill your holes from the inside out into a block of wood.
  • Set the box over four stable objects, arranged at the corners to allow air to flow underneath. You may also want to cover the surface under the box to protect it from moisture leakage.

Add perlite

  • Place your perlite into a strainer and run it under the cold tap to soak.
  • Allow it to drain until there are no drips left, then spread it over the base of your grow chamber.
  • Repeat for a layer of perlite roughly 4-5 inches deep.


    • Open your jars and remove the dry vermiculite layer from each, taking care not to damage your substrates, or “cakes”, in the process.
    • Upend each jar and tap down onto a disinfected surface to release the cakes intact.
  • Rinse the cakes one at a time under a cold tap to remove any loose vermiculite, again taking care not to damage them.
  • Fill your cooking pot, or another large container, with tepid water, and place your cakes inside. Submerge them just beneath the surface with another pot or similar heavy item.
  • Leave the pot at room temperature for up to 24 hours for the cakes to rehydrate.
  • Remove the cakes from the water and place them on a disinfected surface.
  • Fill your mixing bowl with dry vermiculite.
  • Roll your cakes one by one to fully coat them in vermiculite. This will help to keep in the moisture.

Transfer to grow chamber

  • Cut a tin foil square for each of your cakes, large enough for them to sit on without touching the perlite.
  • Space these evenly inside the grow chamber.
  • Place your cakes on top and gently mist the chamber with the spray bottle.
  • Fan with the lid before closing.

Optimize and monitor conditions

  • Mist the chamber around four times a day to keep the humidity up, taking care not to soak your cakes with water.
  • Fan with the lid up to six times a day, especially after misting, to increase airflow.


The hard work is over. You’re now ready to sit back, relax, and watch for fruits (while still optimizing and monitoring conditions, of course). Your mushrooms, or fruits, will appear as tiny white bumps before sprouting into “pins.” After 5-12 days, they’ll be ready to harvest. When ready, cut your mushrooms close to the cake to remove. Don’t wait for them to reach the end of their growth, as they’ll begin to lose potency as they mature. It may not sound like a walk in the park, but the money you’ll save, the peace of mind you’ll gain, and the experience you’ll have under your belt will prove well worth it. The best news is, you’ll be able to re-use the same cakes up to three times!

Now, all there is to do is enjoy the fruits of your labor and with the long-term benefits of psilocybin, micro dosing is a facile way to implement psilocybin into your routine. Many who have integrated micro dosing psilocybin mushrooms into their weekly routine report higher levels of creativity, more energy, increased focus, and improved relational skills, as well as reduced anxiety, stress, and even depression. To learn more about micro dosing check out our Ultimate Guide to Micro dosing Psilocybin Mushrooms. Growing your own mushrooms gives you the independence to gain ownership of your mental wellbeing we’ve got you covered from start to finish.
