McKennaii mushrooms are recognised by their thick stems, dense clusters, and wide caps, creating beautiful flushes during the fruiting stage. Under the right conditions, the first mushrooms typically begin to appear within 10 to 14 days.

Each McKennaii Grow Kit comes fully colonised and ready to grow, meaning the mycelium has already developed throughout the substrate. This allows you to start cultivation immediately with minimal effort — simply add water, maintain the correct humidity, and let nature do the rest.

Ideal Growing Conditions

Psilocybe cubensis mushrooms thrive in warm, humid environments with indirect light.

Recommended growing conditions:

Temperature: 18–27 °C
Optimal temperature: 22–25 °C
Lighting: Indirect daylight or ambient room light
Humidity: High humidity with regular fresh air exchange

To achieve the best results, keep the grow bag closed to maintain humidity while allowing fresh air exchange. Condensation inside the grow bag is normal and helps create the ideal environment for mushroom growth.

Small mushroom pins usually begin to form within 10–14 days, followed by full mushroom development shortly after.

How to Grow – Quick Start Guide

Growing mushrooms with a McKennaii Grow Kit is simple and requires only a few steps.

1. Wash your hands and clean the outside of the grow kit.

2. Remove the lid and fill the container with lukewarm water.

3. Let the substrate soak for 8–12 hours.

4. Drain the excess water carefully.

5. Place the grow kit inside the grow bag and seal it using the paperclips.

6. Keep the bag in a warm place with indirect light.

Within 10–14 days, small pins will begin to form. Harvest the mushrooms when the veil underneath the cap begins to tear.

After harvesting, the grow kit can be re-soaked to produce additional flushes.

With proper care, a single grow kit can produce up to four flushes.

Storage & Shelf Life

Store the unopened grow kit in the refrigerator at 2–8 °C.

Shelf life: 3–6 months when unopened

For the best results, it is recommended to start cultivation soon after receiving your grow kit.

Legal & Responsible Use

Magic mushrooms are regulated in many countries. In some regions, grow kits and truffles remain legal products, while in others they may be restricted.

Always check local laws and regulations before purchasing or cultivating.

Psilocybin mushrooms are considered non-addictive, but they can produce strong psychological effects. Responsible use in a safe environment is always recommended.
