About the Mondo McKennaii Mushroom Grow Kit

This grow kit contains a fully colonised Psilocybe cubensis substrate of the McKennaii strain, produced under Mondo’s production standards. Within the cubensis category, McKennaii is recognised for vigorous colonisation, dense uniform flushes and stable fruiting behaviour. The 2100ML format provides a larger substrate volume for those seeking higher total output across multiple harvests.

Growth characteristics

McKennaii is appreciated for medium-fast colonisation, dense flush clusters, strong substrate coverage and a stable fruit structure. Under stable conditions (22–25°C), pins generally appear within 7–14 days. Results vary depending on environmental consistency such as temperature and airflow.

Complete your setup

Pair your kit with practical extras to maintain stable growing conditions. A Fine Mist Spray Bottle helps keep the right humidity, while a Mushroom Growkit Complete Setup brings the essentials together in one package.

Frequently asked questions

What is included in the Mondo McKennaii Mushroom Grow Kit?

Each order contains one fully colonised Mondo McKennaii grow kit in your selected 1200ML or 2100ML size, a grow bag with microfilter and growing instructions. The kit uses 100% mycelium and is ready to fruit on arrival.

What is the difference between the 1200ML and 2100ML versions?

The difference is substrate volume. The 1200ML format is more compact, while the 2100ML format holds a larger volume for greater total yield potential across its flush cycles. Both versions are the same McKennaii strain.

How long before the first flush appears?

Under stable conditions around 22–25°C, pins typically begin forming within 7–14 days. Timing depends on temperature stability, airflow and overall environmental consistency, so individual results can differ.
