Extreme XL Supa Gro Kit 100% - McKennaii: Copious amounts of powerful shrooms

Psilocybe Cubensis McKennaii is an even stronger strain of Magic Mushrooms than the more famous - and harder to cultivate - Hawaiian strain. McKennaii shrooms guarantee a colorful and powerful trip to outer space!

This Extreme XL Supa Gro kit contains all you need to grow an extra-large crop and contains 2100ml of mycelium, which also can be used for several flushes.

The grow boxes are constructed with a special technology, and specific fillers are used so you don’t have to soak the kit before setting up for your first flush. The included Supa Gro bag allows for clean air circulation.

    kann man nichts falsch machen
    ertrag , wie trip oder optic mitck kann man nichts falsch machen jedoch bedenken mck sind sehr stark und werden einen gefallen


    Its a very big harvest and very strong mushees :) I can recommend for experienced trippers!


    Super Satisfied
    Very decent first flush and AMAZING experience! Much, much more powerful than usual, though - a moderate dose delivers about the same as big doses tend to. This is worth taking into account. Highly recommend.


    On my first flush and the box is packed, but was slow to start. Then after introducing a heat mat they took just days to fill the bag - 70 + mushrooms and counting. Very happy. Looking forward to seeing the results on the second flush


    Not great
    Not good batch. Low yield and not value for money.

    Best custumer service
    The kit was defective, can happen... only few mushroom grow on it, but zamnesia team is the best, and after a quick conversation they understand the situation and send me another one...hope this will be better Big up zamnesia


    box schlecht
    ich konnte die mckennii leider niemals ernten. ich glaube ich schmeiße sie jetz weg, normal sind die fruchtkörper in einem monat ernte bereit. die box steht jetz mehr als 2 monate. zum ersten mal das sie nicht kommen. klima und ernährung wurde eingehalten. mfg Ritsch Simon ps währe nett wen si nachsenden könnten
