McKennaii XL Magic Mushroom Growkit 2100cc

McKennaii XL Mushroom Grow Kit – Mondo 2100cc

The McKennaii is the most powerful Psilocybe cubensis variety in our range and is named after Terence McKenna, the famous American ethnobotanist, philosopher and advocate of psychedelics. McKenna was an influential thinker who introduced the Western world to the deeper aspects of the mushroom experience. The Mondo 2100cc XL grow kit offers you the opportunity to cultivate this legendary strain at home with maximum yield.

Characteristics of the McKennaii strain

The McKennaii produces medium to large mushrooms with thick, sturdy stems and conical to dome-shaped caps. The colour ranges from light brown to golden brown, often with a characteristic dark ring around the edge of the cap. This strain grows slightly slower than some other varieties but more than compensates with its exceptional potency and impressive appearance.

With a strength of 5 out of 5, the McKennaii is exclusively suitable for experienced psychonauts. The effects are intensely visual with vivid colours, complex geometric patterns and deep introspective moments. Users often report philosophical insights, a strong sense of connection with the universe and intense emotional experiences. Respect this powerful strain and start with a considerably lower dose than you are used to from other cubensis varieties.

XL format for maximum yield

This Mondo grow kit has a capacity of 2100cc, considerably larger than standard kits. The larger substrate volume results in more and larger mushrooms per flush. Ideal for experienced growers who want to get serious with this powerful strain.

What's in the kit?

The Mondo McKennaii XL grow kit contains a fully colonised 2100cc growbox. The substrate is ready for use, you just need to create the right conditions. The kit can produce multiple harvests (flushes) when you follow the instructions correctly.

Growing conditions

Place the kit in a spot with indirect light and a stable temperature between 20-25°C. Keep the substrate moist but not soaked. Ventilate briefly each day to allow fresh air in. After each harvest, you can reactivate the kit by submerging the substrate in cold water.

Storage

For best results, set up the kit immediately upon receipt. If necessary, you can briefly store an unopened kit in the refrigerator (2-8°C).

Safe tripping

Given the extreme potency of the McKennaii, proper preparation is essential. Ensure a comfortable, familiar environment and preferably trip with a sober trip sitter. Always keep a Mushroom Stopper within reach to soften an overly intense experience.
