Jack Frost Liquid Culture – Cloud920

About the Jack Frost Liquid Culture

Jack Frost is a purpose-bred Psilocybe cubensis hybrid associated with the TAT Syndicate and breeder Dave Wombat. The lineage is generally dated to around 2018–2019 and combines True Albino Teacher (TAT) with Albino Penis Envy (APE).

The resulting phenotype is recognised for its striking white appearance, substantial caps, pronounced blue bruising and distinctive spore characteristics. Jack Frost has also attracted attention within the mycological community because of reported analytical data suggesting above-average tryptamine levels.

Cloud920 maintains Jack Frost as part of its Hybrid Fusion Series. The culture is available as a liquid culture syringe within the Cloud920 cubensis liquid culture range.

The Cross Behind Jack Frost

Jack Frost was developed by Dave Wombat, associated with the TAT Syndicate, through a cross between True Albino Teacher and Albino Penis Envy.

TAT contributes the characteristic albino appearance and genetics associated with the Teacher family, while APE contributes the substantial stem structure and genetic characteristics associated with the Penis Envy group.

The combination was selected for its unusually pale phenotype and distinctive morphology. Jack Frost subsequently became one of the better-known modern cubensis hybrids, with descriptions appearing across specialist mycology communities and publications.

Its documented parentage gives it a clearer genetic history than many unnamed or poorly documented community hybrids.

Distinctive Appearance of Jack Frost

Jack Frost is particularly easy to recognise because of its almost entirely white appearance. Caps may begin with conical or convex forms before becoming broader and flatter as they mature. Large specimens have been reported within community observations.

The stems are generally white and substantial, sometimes displaying irregular or textured surfaces. Pronounced blue bruising can develop following handling.

One of the most unusual characteristics is its spore-print colour. Rather than the dark purple-brown appearance associated with many standard P. cubensis varieties, Jack Frost is commonly described as producing white to very pale purple spore prints.

This combination of an albino phenotype, substantial morphology and unusually light spore colour makes Jack Frost particularly distinctive for microscopy.

General Characteristics of the Hybrid

Jack Frost has a reputation for having a more specialised growth profile than many traditional Heritage cubensis varieties. Community descriptions frequently highlight its rhizomorphic mycelial appearance and unusual environmental preferences.

However, cultivation reports vary considerably, and conditions described by individual growers should not be regarded as guaranteed characteristics of every culture. For research purposes, morphological differences can also occur between individual specimens and generations.

Researchers interested in comparing Jack Frost with another modern hybrid can explore the Makilla Gorilla liquid culture.

Jack Frost Potency Profile

Jack Frost is one of the community hybrids for which analytical potency information has been reported.

Data associated with Oakland Hyphae testing has placed some Jack Frost samples at approximately 0.83% total tryptamines by dry weight, with reported peak results approaching 1.0%. These figures are above the commonly cited range for many P. cubensis samples.

Such results should nevertheless be treated as sample-specific rather than as a guaranteed specification for every Jack Frost culture. Alkaloid concentrations can vary according to genetics, environmental conditions, maturity and post-harvest handling.

What You Receive in Your Cloud920 Syringe

This product contains one 10 cc Cloud920 Jack Frost liquid culture syringe, supplied with a sterile needle.

The syringe contains Jack Frost mycelium suspended in Cloud920’s nutrient medium. Cloud920 states that its cultures are produced under controlled laboratory conditions, with quality-control checks covering characteristics such as viability, sterility and morphology.

Jack Frost is available in several Cloud920 formats; this particular listing refers to the liquid culture syringe.

Storage and Handling

Store the syringe according to the manufacturer’s instructions and the conditions stated on the product label.

Keep it upright and protected from direct light, excessive heat and freezing temperatures. For microscopy and mycological research, appropriate sterile handling and laboratory hygiene should always be observed.

Microscopy and Mycological Research Only

Jack Frost liquid culture is supplied strictly for microscopy and mycological research purposes.

The legal status of Psilocybe species and psilocybin-producing fungi varies substantially throughout Europe and other jurisdictions. Possession, cultivation or distribution may be restricted or prohibited depending on local law.

Always verify the legislation applicable in your country before purchasing, possessing or using this type of research material.

Frequently Asked Questions

What does it mean that Jack Frost is a hybrid cubensis culture?

Jack Frost is a deliberately developed hybrid combining True Albino Teacher (TAT) and Albino Penis Envy (APE) genetics. It was selected for its pale phenotype, distinctive morphology and characteristics associated with both parent lines.

What makes Jack Frost visually different from standard cubensis?

Its most obvious feature is its predominantly white appearance. The combination of pale caps and stems, pronounced blue bruising and unusually light spore prints gives Jack Frost a distinctive microscopic profile.

How is liquid culture different from a spore syringe?

A spore syringe contains fungal spores, whereas a liquid culture contains established mycelium suspended in a liquid medium. They therefore represent different forms of fungal material and have different applications within microscopy and mycological research.

How should I store the Cloud920 Jack Frost syringe?

Follow the storage instructions supplied with the product. Keep the syringe upright, protected from direct light and extreme temperatures, and use it within the stated shelf life.

Why does this product state “for microscopy and mycological research”?

Regulations concerning psilocybin-producing fungi differ significantly between countries. Some jurisdictions restrict or prohibit possession, cultivation or distribution. The product is therefore supplied for microscopy and mycological research purposes only. Check the legislation applicable in your location before use.

Is the Cloud920 Jack Frost culture laboratory verified?

Cloud920 states that its liquid cultures are produced in a controlled laboratory environment and undergo quality-control checks covering characteristics including viability, sterility and morphology. For current batch-specific information, storage requirements and product specifications, refer to the documentation supplied with the culture.
