McKennaii Magic Mushrooms
McKennaii Magic Mushroom Information.
Summary:
Rumored to be a tribute to the great American psychonaut Terrence McKenna, the McKennaii variety of psilocybe cubensis Magic Mushrooms first appeared in Dutch smart shops shortly after his death.
Although the McKennaii variety has been reported to be more potent than the Hawaiian Copelandia cyanescens strain, which would make it the strongest cubensis variety available (chart below for reference). This claim is debated, however, with some claiming this the McKennaii is a common cubensis variety wrapped in a clever marketing wrapper.
| SPECIES | % PSILOCYBIN | % PSILOCIN | % BAEOCYSTIN | REFERENCE |
| P. cyanescens | 0.85 | 0.36 | 0.03 | Stijve and Kuyper 1985; Repke et al. 1977 |
| P. cubensis | 0.63 | 0.6 | 0.025 | Gartz 1994; Stijve and de Meijer 1993 |
How to grow Mckennaii Mushrooms
This subvariety is considered easy-average to grow. The simplest way to grow this psychoactive mushroom is to fruit directly from the bag.
However, if you are looking for more hands-on experience, we would recommend using a grow-chamber setup using grain spawn and a manure-based substrate. We have found that the easiest grow chamber setup consists of using a tin container. You can read the full post on how to grow mushrooms using tin containers here.
Below is a summary of this method:
- Innoculate grain bag with 3-5cc of Mckennaii liquid culture or spores via spore syringe.
- Store the inoculated grain bag in a dry area for colonization making sure to maintain a substrate temperature of 84-86. Colonizing mycelium generates its own heat, so an ambient room temperature in the high 70s is recommended.
- Once fully colonized, prepare the tin container and begin layering the substrate and colonized grain. Begin and end with a layer of the substrate.
- Set aside for re-colonization (10-14 days)
- Prepare the li by adding fresh air holes and cover with micro-pore tape.
- Replace the lid and place the tin into fruiting conditions. Reduce the ambient temperatures to reduce the substrate temperatures to 74-78 degrees F.
- Mist the inside of the chamber lid when needed.
- Harvest
Mckennaii Magic Mushroom Growing Parameters:
| Preferred Substrate(s): | Various grain types, compost, pasteurized dung/straw |
| Substrate Temperature (Colonization): | 84/86 degrees F. |
| Substrate Temperature (Fruiting): | 74/78 degrees F. |
| Humidity/FAE | During Colonization: 100%RH, 0 FAE: During Fruiting: 90%RH, FAE 2-5x per day |
Note: Substrate temps should be measured internally using a probe thermometer. We’ve found that multi-probe thermometers, such as this dual probe and this quad probe thermometer are easy and very accurate.
