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.

    Moi malheureusement, rien n'a poussé. C'est la 1re fois que ça m'arrive. Pourtant je suis un amateur, pas un professionnel, mais je m'y connais quand même un peu. Et là, rien du tout.

    Juste incroyable
    Hello, Vous pouvez y aller les yeux fermés, c'est un truc de fou ces grow bag. Sur le site la comme ça quand tu débutes ça fait "compliqué" alors que pas du tout. Habitué des kits classique, en plastique avec bunk, le frigo et tout ça. Avec tout les résultats aléatoires liés aux manipulations qui même en faisant TRES attention peuvent amener des contaminations. La pour le coup le "READY2GROW" se sac est prêt comme son nom l'indique. Le pain est massif ça change des boîtes c'est même surprenant, le sac est "scellé". Y'a juste à déplier, mettre à la lumière indirecte, bonne température et.... attendre. en 10/15 jours ça commence et après en 5 jours c'est explosif la croissance. la en 20 jours près de 400Gr frais et encore les Temp. n'étaient pas optimales (plutôt environs 18 degrés au lieu des "23" attendus). Tu peux faire large mieux Y'a beaucoup, les champi sont "lourds" et extrêmement bleutés. La récolte et un peu "compliquée" les bestioles sont bien agrippées au substrat (tu m'étonnes vu le poids), difficile de ne pas abimer le pain. On verra j'ai déjà vu des 2ième flush hyper impressionnant en version boite avec ce genre de base. Que du bon, la petite différence ce prix ça les vaut facile. Moi ça sera que du ready2grow à présent, en plus sympa les variétés "hybride" proposées J'ai tenté ces BAG suite à un dédommagement commercial de Zamnesia, qui sont toujours au top en cas de soucis ça fait plaisir.

    Amazing , profound experience !
    The "McKennai grow kit " produced 165 grams of mushrooms at 21 days of growing. Waiting for the second flush. I consumed 90 grams fresh. I am 100 kilos. Process: - cut shrooms to pieces (1-2 cm) - put in big glass - juice of 4 fresh lemons - let simmer (stir occasionaly) for 30 mins . -grind (easier consumption) - add soda water (easier to swallow) Drink . In 1 hour I started taking off and for 5 hours I had the most amazing trip, a pure overwhelming wave of bliss,hypersenses and self-knowledge. Amazing vision, layers of colours , 3d moving objects. Very nice conversation with friends co-travellers. A lot of yawning . Being relaxed and covered is helpfull. Beautiful easy listening music, essential. Profound experience . Amazing . PS1: The MacKennai kit always seems to satisfy me . Will order again asap.
