Description
McKenaii Mushrooms, unique of their kind
The McKennaii mushroom grow kit is a laboratory hybrid created in honor of the American writer, researcher, and psychonaut Terence McKenna, known for his numerous books on magic mushrooms. This variety of Psilocybe cubensis is famous for its potency, which is even rumored to surpass that of Copelandia cyanescens, also called "Hawaiian". Furthermore, it stands out for its abundant production and its highly philosophical journey, making it a unique experience.
What are McKenaii Mushrooms like?
McKennaii mushroom variety fungi usually measure around 10 cm, with a thick, vigorous white stem, and a round, orange-brown or dark brownish cap, which makes them very recognizable. Although they do not reach a very large size and their shape can be somewhat thin and slender, they usually grow in large quantities, which makes their cultivation simple and very productive.
Effects of McKenaii Mushrooms
McKennaii mushroom grow kits stand out for their high psilocybin content, which translates into a powerful and intense effect. This variety combines a strong visual load with deep introspection and a markedly philosophical character, thus promoting creativity and inner exploration.
Production of McKenaii Mushrooms
The cultivation of the McKennaii mushroom grow kit requires special attention to obtain optimal harvests, as it is quite sensitive to heat and humidity. Maintaining a clean environment and closely controlling temperature and humidity are key to maximizing production and cultivation duration.
- Ideal temperature for cultivation: between 22 and 25 ºC, with 24 ºC being the most recommended.
- Optimal humidity: between 60 % and 80 %.
- Time until the first harvests: between 15 and 20 days.
- Total production: between 200 and 400 grams, depending on care and environmental conditions.
- Number of harvests: up to 4 or 5 can be obtained, provided good hygiene and constant conditions are maintained.
- The first harvests are the most abundant; subsequent ones tend to be smaller.

To harvest McKenaii mushrooms, gently twist them with your fingers, leaving the base of the stem; this will help subsequent fruiting.

Shipping: it arrived in one business day. Truly spectacular. There was a small issue with the payment (with crypto) totally unrelated to GB but rather with their payment provider, but they solved it for me instantly; in fact, I mention it more to highlight the team's efficiency than the problem itself.
Cultivation: it was the first time I grew a mushroom kit. I think the rainy and sunless days didn't help much, it took a long time for the first primordia to appear, about 15 days, and thanks to customer service recommending that I close the bag completely until they appeared, they did. Then they grew slowly and not the healthiest (ventilate well once they appear). I ended up harvesting the first batch which yielded about 40g (not much) and with quite small mushrooms. I surely did something wrong, but I highly value GB's customer service; I sent them photos and they gave me recommendations, tips, and following them helped a lot, the mushrooms didn't turn out perfect but they weren't ruined either. Now, the second batch, surely helped by the sun and warm days, and this time with the GB team's advice from the start, was very fast, in 3 or 4 days there were already primordia and in 8 or 9 days in total I harvested some GIANT and perfect mushrooms, yielding about 120g, which are now drying and I've already started the third batch. I really value the customer service, truly.
Quality: what can I say, first time, truly crazy, spectacular. Logically I'll have to try other varieties, but I'm telling you if it's your first time, try these with peace of mind, you're not making a mistake.
Advice: the QR instructions are fine, but don't stop watching videos, forums, the blog on this same portal, etc. Depending on the area, the climate, and I suppose the variety, you'll have to do one thing or another differently. And don't hesitate to consult the team by email as they know a lot and respond instantly.
Thank you!!

Now they come pre-hydrated, I think they didn't before, this way the risk of accidental contamination is avoided :)

I’ve been buying stuff from GB for sometime now and I couldn’t rate them high enough
Service, postage, answers to all my questions, enquiries, 10 out of 10
Recently my grow kit turned out to be contaminated and they sent the replacement one in no time
And the magic couldn’t come out more beautiful
Thank you GB for being such a great company along the way and in a sense of the word
You rock ??????

It arrived in 2 days but it was contaminated, after talking to customer service they replaced it at no cost and it arrived the next day, I am very happy with the service received and the cake has fruited after six days very abundantly waiting to collect the first harvest, I have the cake in a propagator with artificial light 12 hours a day and it works very well, in summary I was wary of buying this product online but it has turned out to be a very pleasant surprise in every sense, 100% recommended
