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.

    Achat de trois kit de Mckenaii , tous reçu en très bon état. 2 des kits ont très bien poussé ( 4 récoltes par kit pour environs 150 grammes sec ) Pour le 3 ème petit problème de contamination et c'est la que le service client nous propose de nous renvoyer un kit au choix ou un bon achat ! Que dire de plus à part que ZAMNESIA est toujour au top ! Pour ce qui est du trip 2/3 grammes sec et c'est trip garanti Merci :-)

    So terrible kits
