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.

    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

    Seems the best ever tried
    But why can't they make it so that it grows only on top? I often find that it pins only at the bottom. They might use black plastic boxes. I take it out of the plastic box and place it inside a plastic container on a holder, then it is allowed to grow from all sides.


    Not as expected
    First harvest was ok, 29gr dried, but only 2/3 of the surface of the mycyllium gave mushrooms. Second harvest only 6 grams dried. 3rd harvest only 3 small mushrooms. McKenaii mushrooms are a great experience, but I m not satisfied by the yield


    Très bons choix
    Boîte productive, et les champis font le taff, beaucoup de réflexion sur soi-même ! Pas beaucoup de visus cependant


    Experience with the kit
    I am waiting for my 5th flush now, I bought 2 kits and in total I have harvested about 130-140 grams so far from 4 flushes from 2 kits, so about 65-70 grams per kit, in 4 flushes. The first flush was ready to be harvested 2 weeks after I started the process, the first pins were out in a week, the rest of the flushes were ready to be harvested within a week or so
