Jack Frost Mushrooms

If you're exploring the world of exotic fungi, Jack Frost mushrooms are one of the most eye-catching and coveted strains among enthusiasts. With their frosty-white, shimmering caps and powerful properties, these mushrooms have become a popular topic in the mycology and psychonaut communities alike.

In this post, we’ll break down what Jack Frost mushrooms are, their genetic lineage, and a step-by-step guide to growing them successfully. Whether you're a beginner cultivator or just mushroom-curious, this guide has everything you need to get started.

What Are Jack Frost Mushrooms?

Jack Frost mushrooms are a hybrid strain of Psilocybe cubensis, the most commonly grown psychedelic mushroom. They are the result of a cross between two legendary strains:

Albino Penis Envy (APE) – Known for its potency and ghostly white appearance.

True Albino Teacher (TAT) – A variant of Golden Teacher that carries the albino gene.

The result is a unique, albino mushroom strain with a silvery, icy-blue hue — hence the name Jack Frost. These mushrooms are often admired for their aesthetic beauty, dense structure, and potent effects, which many describe as deeply introspective, visual, and emotionally intense.

Why Grow Jack Frost Mushrooms?

Aside from their stunning look and mind-expanding potential, Jack Frost mushrooms are sought-after for several reasons:

Strong potency: They’re generally considered more potent than standard cubensis varieties.

Genetic stability: When grown from a spore clone or culture, they tend to produce consistent results.

Great for microscopy or research: Especially when buying spore prints (legal in many regions for non-cultivation purposes).

How to Grow Jack Frost Mushrooms: Step-by-Step

Disclaimer: This guide is for educational purposes only. Psilocybin mushrooms are illegal to cultivate in many regions. Always check your local laws.

1. Start with Spores or Liquid Culture

Spore Print or Syringe: Jack Frost spores are typically available online in markets focused on microscopy or research.

Liquid Culture: For more reliable results, many growers prefer to work with an LC (liquid culture), which is a nutrient-rich solution pre-inoculated with mycelium.

2. Prepare the Substrate

Jack Frost mushrooms thrive on nutrient-rich substrates. The most popular choice is:

Brown rice flour (BRF) cakes for beginners

Coco coir + vermiculite + manure (CVG) for bulk growing (recommended for more experienced cultivators)

Sterilize your jars or bags in a pressure cooker to eliminate contaminants.

3. Inoculate and Colonize

Inject your spore syringe or LC into your sterilized substrate using clean techniques (ideally in a still air box or with a laminar flow hood).

Colonization time: 2–3 weeks, depending on temperature (ideal: 75–80°F or 24–27°C)

Wait until the entire substrate is covered in white mycelium before moving on.

4. Introduce Fruiting Conditions (Fruiting Chamber)

Once fully colonized, introduce the substrate to fruiting conditions by placing it into a monotub or fruiting chamber with:

95% humidity

70–75°F (21–24°C)

Indirect light (12 hours per day)

Fresh air exchange (FAE) 2–5x per day

5. Harvest and Dry

Jack Frost mushrooms will begin to pin (tiny baby mushrooms) within 7–10 days after fruiting conditions. Harvest them:

Just before the veil underneath the cap breaks

Using clean hands or scissors

Dry immediately using a dehydrator (ideal) or desiccant method

Is Jack Frost Worth Growing?

Absolutely. If you're experienced in mushroom cultivation or just starting out and looking for a strain with visual appeal, strong genetics, and a powerful reputation, Jack Frost is an excellent choice. Growing this strain will not only reward you with potent results but also teach you the basics of cultivation, sterile technique, and the beauty of mycology.
