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.

    Pretty good but instructions should'nt be followed as such
    We bought several kits and and one of us grew them with light (as suggested in the instructions) and the other didnt. The one who didnt' got 3x more mushrooms than the one who used the light. So can be great but instructions arent' always the best. Anyways, practice makes perfect ;)


    Flush wasn't that good.
    But I informed about this and took contact to the support, coz I've ordered many other boxes and the flushes have been great. There w s a problem with the box so I got a new one!! Zamnesia is Tha best there is.


    Very quick delivery and first flush within a week great buy .

    Fantastic Kits
    I bought two kits and harvested around 60 to 70 grams on my first flush. I had zero issues with anything during the growing stages very easy to use.


    No mycelium
    This is my 4th day with Mckennaii kit which look dried out and got no trace of mycelium. Im curious if someone else got this issue too. Hopefully Zamnesia will replace my defective kit.


    very good service
    my order got messed up with delivery service but zamnesia replaced it no problems highly recommend
