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

I have to say, this company has excellent customer support. One package arrived, and the Tupperware pot was broken, with holes everywhere...damaged in transport, I guess. However, one quick email to mention it, and they sent me a replacement pot, no questions asked. Delivery was quick. That is excellent customer service, and will keep me as a valued customer. Well done GB...

Good kit.
Good delivery, truck with refrigerator.
Everything worked out great. I'm in the mid of 2nd grow and they are vigorous. Took 3 days to reboot the kit.
Keep temperature and humidity stable and you'll see good results. I didn't even use meters.
GB shop trust worthy every time. They even shared the supplier when asked.

The new size plastic bag is a good improvement, makes it all more manageable. I have grown these under blue LED lights and the results are spectacular. Highly recomended! Put bag in a small carboard box lined with mylar and your blue LEDS at 12/12 light cycle. Voila!
