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.

Supa Gro magic mushroom grow kits are grown by mycological experts and contain extremely healthy mycelium.

    J’ai reçu mon kit le 19 juillet nous sommes maintenant le 2 septembre résultat 2 champignon dans le kit qui son pas très beau et plein de champignon qui pousse sous le mycelium j’ai pourtant tout respecter à la lettre. mon kit se trouve dans le carton d’ambalage comme écrit sur la notice donc ce n’est pas à cause de la lumière mais une erreur du fournisseur je suis vraiment déçu..


    Bought this back in october 2018, I only let a review because I forgot to do so... I remember this kit was in sale so I paid 10 bucks less and was absolutely worth the investment! I set up the kit directly after I received it and as it was my first kit took great care of every single day with joy and excitement! The shrooms showed me a lot of gratitude as 13 days later I harvested 440g fresh! Had another small flush of 100 grams. Really good experience !


    Bof au début mais génial a la fin
    Boite achète mi juin du coup grosse chaleur la box n’a rien donner apar 5-6 petit champis. Fin de la période chaude avec beaucoup de pluie là box a vraiment commencé à ce développer et la magie presque 180g (18g sec) en un cycle!!! Je recommande fortement mais a ne pas tenter en période de forte chaleur si rien n’est fais pour que la pièce reste a bonne température.


    Nn compatte monte da questo sito
    Solo una spesa di solidi inutile su 3 kit nemmeno una e andato in produzione . Ho contattato il servizio clienti e nn si sono nemmeno segnato di rispondermi . Mai piĂą compreso da questo sito Mai piĂą. E solo uno spreco di soldi per


    Works great!
    Had some trouble at first but the support helped me out. This works as advertised!


    Worst kit I ever bought, so disappointed
    This is really a pain in the ass, 84€ to get way less than a normal kit. I have a thermostat that keeps the kit at 23 degrees, I did exactly as it says. Not my first kit, but definitely the worst I had and the most disappointing because it cost 2 times the price of a simple kit... I won’t buy kits anymore, way too much money for too much uncertainty.


    Lasciate perdere
    Pacco arrivato Come prestabilito Purtroppo la prendo la scatola vera e propria della Kit hanno dato che non c'era un Sigillo di manomissione non preoccupandomi troppo.... ma dopo un po' di tempo è comparsa della muffa Purtroppo questo Kit non era stato ben sterilizzato quando è stato spedito meglio acquistare direttamente le spore e farle Per conto proprio


    Great kit!
    4 stars because my mistake... Highly recommend! Good strength...


    Agradecido con Zamnesia.
    Era la primera vez que probaba un kit supa gro y lamentablemente no pudo sacar los brotes que buscabamos. Me puse en contacto con zamnesia y tras varios consejos tampoco pudimos salvarlos. Estuvieron muy atentos del seguimiento y supieron compensar con creces este inconveniente. Una vez mas, muy satisfecho con el trato, la atencion y la forma de trabajar de este equipo.


    Champignon puissants, rendement correct
    Une bonne première flush mais une deuxième beaucoup plus décevante, choc au froid fait ce matin, la 3eme flush sera en route ce soir ;) De par expérience les mckkenai peuvent surprendre par leur irrégularités de rendement à chaque flush, la dernière box m'en a fait 7 ;) la plus grosse étais la 4 ème ;) Voyage garanti avec cette variété
