How to Grow Psilocybe subtropicalis
Psilocybe subtropicalis, a fascinating and lesser-known psilocybin mushroom, has begun to pique the interest of cultivators worldwide. Its unique characteristics and resilience make it an intriguing choice for those looking to expand their mycological horizons. This guide, drawn from my personal experience, aims to demystify the cultivation of this captivating species. So sit back and get ready to learn all about how to grow Psilocybe subtropicalis.
A Journey into the Subtropicals
Unlike its more famous cousin, Psilocybe cubensis, subtropicalis thrives in conditions that might surprise seasoned cultivators. It prefers a drier environment and exhibits a tenacity that allows it to fruit for extended periods. While my experiences provide a solid foundation, remember that every culture is unique, and your journey may unfold differently.
Spawn Selection and Preparation
While I’ve found success with Wild Bird Seed (WBS), or plain millet, feel free to experiment with other grains. The key lies in proper preparation. Once your chosen grain is fully colonized, break it up and submerge it in water overnight. This hydration step ensures your mycelium is ready to conquer the substrate.
Creating the Ideal Substrate
CVG is the preferred and easiest substrate to make for this type of mushroom. Coco coir, a staple in mushroom cultivation, forms the base of our substrate. However, subtropicalis benefits from a crucial amendment: gypsum. Adding roughly 1/4 cup per brick of coir enhances water retention and promotes robust pinning.
Here’s where things get interesting. Unlike cubensis, subtropicalis prefers a substrate on the drier side. Imagine the consistency of a wrung-out sponge – that’s your target. This subtle shift plays a significant role in the fruiting process.
Finally, unlike p. cubensis, this species seems to do better in unmodified tubs. So choose a container of your choice, and put the drill away.
Casing Layer
Casing, the protective layer atop the substrate, is essential for many mushroom species. Similar to other exotic species, subtropicalis does require a casing layer for fruiting. However, unlike pan cyans, this species prefers a drier casing layer. This allows the mycelium to partially colonize the casing, leading to more even and prolific fruiting. The casing layer could be a simple hydrated coir, or can be more complex. We use our standard casing layer recipe with just a little less water. Find our Subtropicalis Casing Layer Recipe below
2 quarts peat moss (or 2000ml)
2 quarts vermiculite (or 2000ml)
15g (or 2 TBSP) calcium hydroxide (pickling lime) (or 40g (or 5 TBSP) calcium carbonate) mixed into
<1 quart water (roughly 900ml)
Fruiting Conditions: A Departure from Tradition
Here’s where subtropicalis truly sets itself apart. Forget the classic monotub setup. This species thrives in environments with consistent airflow. Think unmodified tubs or containers with an upside-down lid, creating a gentle, even flow of air.
Another unique aspect: subtropicalis rewards patience. Flushes can continue for months, a testament to its resilience. When re-casing for subsequent flushes, completely remove the old casing and any lingering pins. This ensures the healthiest and most visually appealing fruits.
Embracing the Unexpected
Growing Psilocybe subtropicalis is a journey of discovery. This species thrives on misting and boasts an impressive lifespan. Don’t hesitate to experiment and adapt these techniques to your unique environment.
Remember: This guide is a starting point. Embrace the learning process, and you’ll be rewarded with a deeper understanding of this fascinating mushroom. I hope that this guide gave you the fundamentals of how to grow Psilocybe subtropicalis. Please comment with any questions.
