McKennaii (Psilocybe McKennaii)

McKennaii shrooms are named after the American ethnobotanist Terence McKenna. He and his brother Dennis blazed the trail for the responsible use of psychedelica and gave shrooms in particular the reputation they enjoy today. Not for nothing was their last name given to these shrooms. McKennaii Magic Mushrooms are the most visual variant from the collection of complete shroom cultivation sets. Under the influence of these shrooms you can experience trips which are completely out-of-this-world. It is the strongest recreational shroom but can also be used for spiritual and shamanistic purposes.

These shrooms can make you nauseous. That is part of it but the brief feeling of nausea will pass on its own. Rather not? Then take a lower dose or try a different shroom from this particularly potent McKennaii.

Growing Your Own Shrooms in 10 Steps

Brief instructions. For complete instructions, please refer to the detailed manual under the title "Documents" on this page.

  1. Wash your hands and the outside of the grow-kit.
  2. Using a clean fork make holes in the top layer of the grow-kit (remove lid).
  3. Fill the kit with lukewarm water to the edge and put the lid back on. Allow to soak for 8 to 12 hours.
  4. Pour off any surplus water. Drain the kit for 10 seconds.
  5. Add lukewarm water to the grow bag. 250 ml for 250 cc and 500 ml for 1200 cc. Place the kit in the bag and make sure that the water does not end up in the kit itself.
  6. Close the bag with a cover and fix it with the two paperclips.
  7. Place the grow kit away from direct sunlight and not under a lamp or on the heating. The ideal temperature is 20 to 25 degrees Celsius.
  8. After about 2 weeks the first mushrooms will appear. Some species may take a little longer than others. Be patient and proceed to the next step when you see small buds appear.
  9. See any little mini mushrooms? Open the bag every day for fresh air and humidify the inside of the bag (but not directly on the kit) with a plant sprayer on the spray position. This will keep the fungus alive. Work clean at all times and make sure you don't contaminate the kit.
  10. Harvest when the flesh under the cap is threatening to come loose. Pull the mushroom out as completely as possible by twisting it gently left and right.

Once again? You can! Remove the old and dead mushrooms and place the kit overnight in the refrigerator preferably at a temperature of 5 to 7 degrees Celsius. Repeat the steps from step five but spray the grow-kit extra well before going any further. Not soaking wet but with enough lukewarm water.

Work Cleanly

And another tip. Go to work unbelievably cleanly. We’re talking gloves and a face mask. A shroom cultivation set is extremely sensitive to outside contamination whereby other fungi can grow better than your shrooms.

Customer Reviews

Great product. As a first time grower I made lots of mistakes and unfortunately had to cancel after the second flush. There would be the potential for at least one more. Got out 9g dried (2 flushes). Def recommended!
