Supa Gro Kit 100% 'McKennaii'


Psilocybe Cubensis McKennaii is said to be an even stronger strain than the popular and famous (and hard to cultivate) Hawaiian (Copelandia cyanescens). It definitely is for the more experienced, visually interested psychonauts due its very philosophical trip with a strong visual component. This grow kit contains a 100% colonized 1200ml cake.

Supa Gro Kit 100% 'McKennaii': Allegedly even stronger than the Hawaiian

Psilocybe Cubensis McKennaii is allegedly an even stronger variety than the famous and popular (and hard to grow) Hawaiian (Copelandia cyanescens). This strain is obviously for the more experienced psychonauts as it provides a very philosophical voyage with a strong optical component. These grow kits contain 1200ml of fully colonized substrate, ready to grow - this is a 100% package! All you need a little patience. Godfather of this strain is the American writer, teacher, researcher and psychonaut Terence McKenna.

    Toujours au Top
    Bon bah rien de spécial à dire, au niveau des effets c'est dans mon TOP 3 en matière de champignons, à base de 4.5g ou 5g sec par prises et 4 semaines minimum d’écart entre elles. Au niveau des flushs j'entame le 3eme, en 2 flushs j'ai obtenue un peu plus de 25g après dessiccation.


    Very good feelings
    Very good type. Spiritual and deep feelings and Visuals. The best for us


    Grows well, is very potent and an all round good kit.


    What a shame
    Complete dud despite very closely following the instructions. I've had packages from Zam before that worked fine but this one did next to nothing. Hasn't put me off Zam but has put me off this product :(


    Probably one of the best purchases of my life
    Jaw dropping visuals and profound ideas, nice fat shrooms from the flush too average about 30g wet per fruit. Customer service and advice was top notch. Will absolutely be using again. Thanks guys!


    Top in visual and extasy
    I wanted to do a complete review on this, so I had to wait for almost two months to do it. I've come up with almost 400gs (fresh) from 5 flushes, thanks to the heating mat. Drying process: epsom salts. Dried: 36gs. I've also tried with oven at min temperature but it was a total failure: they lost all their power, really almost everything of it. I've taken many in my life, not so often, but really, many, and these kids are the top: I've never had these kind of unexplainable complex geometrical visuals, mind is completely pure and everything can be controlled well (I still haven't tried the highest doses, but 1g is yet a nice trip). Only thing is the duration, about 3-4 hs, which could also be good if you want to not loose all the day on it. Last but not least: powerful extasy feeling!!


    Mc kennai
    Très bonne variété avec de beaux rendements ( plus de 40 g sec) Très visuelle (lsd like ) et assez puissante. Ce n'est pas la variété la plus euphorique mais de très bonnes aventures ! je recommande


    strong strain
    it´s been my fourth strain so far, and for sure the strongest. Growing is simple and fast, when using a heat mat. I have only two points of critics: 1. The bags are a bit weak, and tend to collapse. 2. I don´t know, how people manage to get out 4+ flushes. Realistically, I had never more than four, where the last flush been a single mushroom. Total yield around 250-400g fresh. With this kit, I had the first time green mold, spoiling the kit after the first flush.


    Insanely powerful !
    Very nice and easy harvest, grew fast, several flushes ! Extremely potent !!!

When I put the kit in the bag, how much water should I spray every day with "100% Mycelium kit Mckennaii"?


It's best to spray 2 to 3 times a day. Don't spray much. One squeeze of your sprayer should be enough. We have made a great instruction video and put it on Youtube. This could also may well be of help:

Hello Do you mean to put the water only in the bag and no water in the box? I have some doubts, because normaly you have to put water in the box. Thanks for an answer


All our 100% Mycelium kits come with a customized manual. To gain the best results, check out our Online Instructions for these kits, here:

Ryan Segal 2013-03-15 16:19:38

So, no casing? Does it need to be 'birthed' and placed in a homemade habitat, or will it grow in the bag the same as the other growkits?


These kits work in a similar fashion. The kit comes with its own bag, but the contents of the box need not be submerged prior to growing. Complete instructions will be provided of course.
