Ready-2-Grow Bag ‘McKennaii’ – Zamnesia: Observe a Legendary Strain With Zero Effort

Note: All Zamnesia Ready-2-Grow Bags now have a small corner cut off the top. Don't worry, this is intentional and makes the bag easier to set up. It has no negative effect on mushroom growth and poses no risk of contamination.

The McKennaii Ready-2-Grow Bag offers a simple and discreet way to observe one of the most fascinating Psilocybe cubensis strains out there. Designed for hassle-free at-home cultivation, this full-auto grow bag provides a sealed, pre-colonised environment—perfect for amateur mycologists and experienced collectors alike. Just place the bag correctly, and let nature do its work.

Who Was Terence McKenna?

This strain is named after Terence McKenna—philosopher, psychonaut, and one of the most influential voices in psychedelic culture. A passionate advocate for natural consciousness expanders, McKenna believed that psilocybin mushrooms held the key to understanding deeper truths. Whether myth or tribute, it's said this strain was developed in his honour—possibly derived from Golden Teacher genetics—to reflect his legacy.

What Makes McKennaii Special?

The McKennaii strain sets itself apart from others in the Psilocybe cubensis family. It produces long, thin stems with small, flat caps and a distinctive darker top with an ochre rim. Observers often notice its striking appearance even in early stages of development. Colonisation occurs best at 21–25°C, and under these conditions, you'll witness robust growth patterns ideal for study.

  • Distinct phenotype with dark caps and slender stems
  • Known as a potent variety
  • Ideal for advanced users interested in observation

How To Use the Grow Bag

Using the McKennaii Ready-2-Grow Bag is as easy as placing it in the right environment:

  • Place the grow kit bag in a well-ventilated area. Avoid cupboards, boxes, or basements.
  • Ensure the bag stands upright and that the internal filter stays in the front, not pressed against the back wall.
  • Keep the grow bag in the shade at 20–25°C. Avoid temperatures above 25°C and blocked airflow, which can harm the mycelium and lower yields.

    Of the less potent varieties, this one is the strongest and produces the best visuals.
