McKennaii XL Mycelium box (2100ML)



Avalon is proud to present the McKennaii Mycelium XL-Box. This McKennaii XL-MyceliumBox is an enhanced Mycelium box with 80% more substrate (2100 CC). The McKennaii mushroom caps can grow into weird shapes, but get the job done properly.

This XL-MyceliumBox contains the mycelium of the Psilocybe cubensis 'McKennaii' strain. The McKennaii mycelium is colonized on a substrate of rye and perlite. The top layer is covered with vermiculite.

Holding the double of the substrate, meaning the double of the expected Thai yield, the XL-Mycelium Box is an enhanced product allowing the formation of exceptionally big Thai mushrooms in an exceptional short amount of time.

Made for the amateur mycologist, the Mckennaii XL-Mycelium kit highly reduces the probability of contamination and it's simplicity of processes will allow you to better focus on the amazing formation of mushrooms bodies. Made with the strongest redefined thai mushroom strains, growing mushrooms was never easier and more reliable.

Because the kits are fresh they need to be set up right away.

McKennaii XL Mycelium box (2100ML)

Sehr gutes Kit! Bin mittlerweile beim 3. Flush. Die ersten beiden haben zusammen ca. 300g frische Shrooms hervorgebracht!
Evaluation: [out of 5 Stars]

best kit i ever seen. it is always HUNGRY to fruit. the 3rd fruiting time was like 24h after the cold shock, a m a z i n g. DONT buy kits from magic-mushrooms-shop.com if you are in doubt, i lost money thinking those were better because they look so much better in person. But deliver nothing, THIS ONES DELIVER BOY OH BOY! I DONT EVEN CARE that my cake is infected now because even like that, is fruiting like BANANAS! Since many many mushrooms grew on the bottom side (i blacktaped the sides), for the 3rd flush I grab the cake and put it sideways (bottom and upper part are left and right). The results are mind blowing, it seems like the cake wanted this since the beggining! awesome guys, thank you very f*cking much

That was the first kit i ordered. Before i have taken mushrooms once and some times trueffels. The Kit came after 5 days, but was broken. So i get a new one. I think the high is more in the head an less visual, but very nice. After the third flush the box i have a mold grwoth. But all in one i get 350g.

Ich weiß nicht ob die Leute mit den schlechten Bewertungen einfach Pech hatten oder vielleicht doch bei der Zucht und dem Trocknen Fehler gemacht haben. Ich bin so überrascht, es kamen 8 Flushes, unglaublich viel Ertrag, bei den letzten Flushes haben ich schon nicht mehr daran geglaubt und habe daher keine Hygiene mehr eingehalten, trotzdem kamen immer wieder neue Pilze. Auch die Wirkung schon bei 1g in Schokolade echt *T*O*P*

Very fast and reliable sendings. Until now i was very satisfied . I have already wrote two mails to the support and did not got a answer back . I bought the XL McKanni Mushroom kit , and it had just Aborts and a bad quality over all . I have bought a B+ Kit that was much more effective so this ain’t my mistake that it won’t work.
I am disappointed that the support did not even answer my messages. So 1 star from my side .

I'm disappointed with the effect. mckennaii should be the strongest, but I enjoyed 8 g and the effect was mild so I took another 4 g of dried mushrooms to make the effect of slag better. 12 g is enough for a medium effect. so those mushrooms are weak. I used to take 7 g Mckennaii and flew in space now I use 12 g and I have mild states and mild visualizations. I'm sorry, but it's not strength anymore
