Mckennaii - Magic Mushroom Growkit

Many have proclaimed this psilocybe cubensis strain as the strongest magic mushroom you can grow, surpassing Copelandia Cyanescens (aka Hawaiians), and making it a very popular choice for experienced psychonauts.

This powerful magic mushroom is named after the famous American ethnobotanist and author Terence Mckenna, a well admired advocate for the responsible use of naturally occurring psychedelic plants. 

With strong visuals and an intense philosophical trip, these beauties will rock your world while opening the doors of perception to your inner self and guiding you through a wonderful journey.


The trip can be spiritual, and for some, profound and emotional. Magic mushrooms produce effects which may include a deep connection with nature, sudden appreciation or joy for life, open and closed-eye visuals, colour enhancement, sensory stimulation, increased sense of humour with fits of laughter, creative and cognitive enhancement, music appreciation, thought acceleration.

Reminder: effects are usually enhanced when experienced with a positive mood, good music and a comfortable environment.


The overall trip can last from 5 to 8 hours, and inexperienced users should start small and up their dosage only after waiting an hour to assess their condition.

Harvest average
Standard (1200cc): 400 - 500 grams
XL (2100cc): 900 - 1000 grams
*Growkits can produce multiple flushes of mushrooms with proper care!


Heating devices: for the best results, please avoid direct contact between the heating surface and the growkit. If you cannot create space, use a piece of cardboard or a folded towel.

Storage: the growkit is ready to grow as soon as you receive it. If you need to wait, the growkit can be stored in the fridge for up to a month. Any longer may compromise the grow results.

I order shrooms for the first time, and I never grow this before.
Packet arrived a few days after, on time. I did not excpect to get so many shrooms !
I probably had to harvest them 5 or 6 times, and i proabably had a total of 45g dry.
I spent 10 days to eat them all, and trust me, I now beleive in God :).


they are comin in 6 days in turkey.. growing now. I'm so excited.. lets look whats gona be..

Everybody loves mushrooms, especially the strongest ones! never tried these ones before but all the other varieties from shayana were great so this one called by the name of the great mushrooms' eater can't be less fulfilling for the mind, i'm just throwing random words in here to reach 100 words
have fun


Exellent service very discreet and received in 4 days one very healthy box of mycelium.its soaking now as I write this.very happy with the service and will definitely recommend shayana and be using you again.
Thankyou shayana shop top service.😊

Very good and fast delivery, i recived a healthy box of mycelium, and it did not take more than some days for the first pins to show. And after just 8 days a had a nice flush of good looking shrooms. I was pretty freaking amazed about how fast these grew, i really did not expect that.


Wow what can I say,my second kit and this type was the more potent I tried these dry first but it took a few hours to come up I only ate about 20gs worth (when fresh not dry) and was tripping for about 6 wanderful hours quite intense but so much fun I didn't want to move a lot maybe that was due to the super silver haze I was toking with the shrooms.i must have got atlases 500gs of fresh shrooms off my second kit wel worth the wait but grows very wel with tepid water in the spray bottle. I done 40gs of fresh on my next adventure very intense I loved every second of it I watched the film dread and then sucker punch two very good films to watch while on shrooms wel done shayana ur my new hero keep up the wanderous work you dudes do thank you

Woopy Shroom this... Arrived on time as usual. 1 Week in more or less.
Growing vise, all excellent. On my 4th flush, and i'm in over 650 g fresh.

The effects and vibes match the name "Mckennaii" Exceptional Vibe. <3
Great process of thought and clarity. Can be intense, and very informative if taken alone, i recommend to prepare a bit, in terms of Inner dialog with the Mushy. List of questions, to put the beautiful energy waves flowing in the desirable direction.

Also Great with ya buddy's. Took some with my sister, perfect bonding agent as one would expect. Easy and emphatic feel, very connective. Definitely will dissolve unwanted belief systems, and rediscover ones identity. Or towards it. :P

All and all. Excellent product and alive, in terms of inhabiting energy. Fairly visual with open eyes, a different galaxy when closed. Long term positive effect after the trip is guaranteed. Productivity, creativity, etc. You name it.

Took from 3-5 g dried. For starting i;d suggest going for 3g.


i got the package after a week. it found a small spot of green mold. after removing the spot everything grew normal. however the end product is very nice and potent.

Fantastic as always. Big love good trip! !


Fast delivery, after 6 days i got the package in Denmark, thanks shayanashop, updates on how the effekt is will come in a few week Gabriel :)

Very very visual trip with 5gr. dry..
Thanx shayana :)))


it arrived in four days, discretely packed, taken quite a while to fruit though, over three weeks and i'm just noticing first few pins, might advice leaving the box to colonise for a couple more days before putting into humidiity bag, will update on potency, yield etc

Holy molly I’ve been growing those for some times now and no words could describe how I feel .
One kit has produced : 261g wet 1st flush then 284 2nd flush then 157 3rd flush going for a 4th one and another kit of the same strain produce some absolue monsters Im on the 1st flush of this kit and it has produced 600g wet the whole box was full of mushrooms and they were literally no open space left it was really difficult to harvest and there were all in block all stuck together they seems extremely powerful as they turned right away into a deep blue they are now in the dehydrator that I could not even close I’ve had to put some weight on it 😅 I wish we could upload some pictures with the reviews so you guys could see that .

I’ve tried a few strain now and McKennai has been my favourite and the one that also produce the most monsters and many fruits also the trip is very good I only trip taking heroic doses and those are a real pack a punch . Awesome shayana 🥳🥳🥳 you guys rock it 🍄🍄🍄
