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

Note: All Zamnesia Ready-2-Grow Bags have a small tear beneath their white filter. Don't worry—it's there for a reason, namely to enhance CO₂ exchange and maintain optimal conditions for healthy mushroom growth.

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
  • Reportedly more intense than Golden Teacher (for theoretical comparison)
  • 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.

    Didnt work
    I'm really disappointed. I placed two orders: one for the McKennaii and one for the Golden Teacher. I received both at the same time and set them up on the same day, following the same instructions. The Golden Teacher has already produced its first flush. I've harvested and dried them already, and that was about a month ago. However, nothing has happened with the McKennaii kit so far. There hasn't been any growth at all. How is that possible? Is it possible to get a refund, or could you send me a replacement kit?

    first grobag, bad luck this time
    I must of been unlucky with bad genetics, they grew fine, albeit small yield, harvested when veil was breaking etc but the mushrooms have zero potency, dried and fresh :(

    Súper!
    Es que son una maravilla. Tardaron unas 2 semanas y medio para empezar a salir. Cuando crecen se quedan enormes. Los compraré nuevamente. Son súper!

    for a great second flush you need
    To give back the water to the mycelium. If a flush was 500gr, put back 500gr of spring water. Easy.
