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.

    Mckennaii grow bag
    I altered the instructions a bit I put black duct tape around the bag and forced the growth upwards and I ended up with 450g of wet and 43g dry I am on my second flush which is not so great so far

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

    und wieder nichts
    Es ist nichts gewachsen, sehr schade. Ich habe es zum ersten Mal gekauft und war gespannt auf viele Pilze, aber es kam nichts dabei heraus. Zweites Produkt von Zamnesia, zweiter komplett Ausfall. Löscht mein Kundenkonto Danke für garnichts...

    Did not disappoint me last time but now
    First flush from two packs where 4 tiny ones because they did not grow for 5 days. Started new flush and hope it will be better. Third one is still growing tiny first ones and I hope nothing will make it suffer that much than two others did.

    Buena calidad. Produccion menor de lo esperado
    Tardo mas de lo esperado (30 dias para la primera cosecha), muchas salian por los laterales y quedaron aplastadas. Creo que no es del todo bueno el intercambio de CO2, porque dio apenas 200g frescas. Calidad muy buena. Con 1g seco viaje muy bueno.
