Amazonian genetics refined by one of the great spore houses

PES Amazonian is a selection from Pacifica Exotic Spores (PES), descended from a wild specimen collected in the Amazon basin. PES was one of the most respected spore suppliers of the early cultivation era, known for rigorous selection and strain integrity. Their Amazonian selection became a flagship product — combining the vigour and large-fruit genetics of true Amazon-basin cubensis with the stability of repeated cultivation selection. The result is a strain that has remained relevant across multiple decades of home cultivation.

Large, vigorous fruits with deep amber caps

PES Amazonian produces substantial fruit bodies with caramel to deep golden-brown caps that are broad and fleshy at maturity. Stems are thick, long, and white, developing a strong blue bruise when handled. The mycelium colonises densely and visibly vigorously — a characteristic often cited by growers as a reliable indicator of the strain’s robust genetics. Spore prints are the deep purple-brown standard of Psilocybe cubensis.

A producer’s strain with a strong potency reputation

PES Amazonian is frequently placed by community members in the higher tier of cubensis varieties for both yield and reported intensity. These are anecdotal assessments — PES itself built its reputation on stable, consistent stock rather than dramatic marketing claims, and the strain’s standing in the community reflects genuine grower experience rather than hype. Conditions, substrate, and harvest timing remain the primary variables as with any cubensis.

Fast-colonising and abundantly productive

PES Amazonian colonises fast on grain and bulk substrates, with full colonisation typically completing within 10–14 days on grain. Fruiting initiates readily at 23–26 °C with adequate humidity and fresh air exchange. Yields are high — the strain flushes abundantly and maintains productivity across three or more flushes. It performs particularly well on manure-based mixes and enriched bulk substrates that allow its Amazonian genetics full expression.

About Psilocybe cubensis vials

Every spore vial in our catalogue contains a single, isolated Psilocybe cubensis strain in a sterile preservation fluid. Cubensis is the most widely cultivated species in the genus, with shared growing parameters across most strains — the differences between strains are mostly visual, behavioural and in subtle yields. The technical specs below apply to every cubensis vial we ship; the strain-specific traits are listed in the table on each product page.

Contents

  • 1× glass vial with 10 ml sterile spore solution
  • 1× sterile 10 ml syringe
  • 2× alcohol prep pads (“alco preps”)
  • Carton box, sealed for shipping

Why choose a spore vial?

  • Long shelf life. Up to 2 years refrigerated — significantly longer than a typical spore syringe.
  • No static charge. Glass vials don’t carry static, so spores stay in suspension and don’t cling to the inside walls. You actually get to use 100% of the spores.
  • Higher spore density. Roughly 1,000 spore grow-parts per millilitre — about double a standard syringe.
  • Resealable septum. The rubber membrane re-seals after each needle pass, so one vial inoculates multiple substrates over time.
  • Compatible with liquid culture media. Vial spore solution is clean for use with LC growth media, where syringes often aren’t.

Practical use

A 10 ml spore vial holds enough solution to inoculate roughly 3 litres of substrate (around 3 ml per litre). Always sterilise the rubber septum with an alcohol prep before inserting a needle, and replace the protective stopper cap between uses. The vial can be drawn from multiple times as long as the septum is sterilised before each pass.

Best practice: transfer to agar or liquid culture first. For the most reliable results, don’t inject spore solution directly into grain. Spores need to germinate before they can colonise, and grain offers no way to spot contamination early. Transferring to an agar plate or to a liquid culture (LC) medium first lets you isolate clean, vigorous mycelium before it ever touches your final substrate. This step typically increases success rates significantly and lets you produce multiple grain bags from a single vial via LC.

Storage

Store the vial in the refrigerator between 2 °C and 8 °C (35–46 °F), dark and upright. Keep the protective septa stopper cap in place when not in use. Do not freeze — ice crystal formation can rupture spores. Stored correctly, a spore vial remains usable for up to 2 years from dispatch. If the solution shows green, pink or orange tints, contamination has set in and the vial should be discarded; faint brownish cloudiness is normal and represents the spores themselves.

A note on legality

Psilocybe spores themselves contain no psilocybin and are legal to possess in most EU countries. Local laws on cultivation and possession of mature mushrooms vary — please check the regulations in your country before going further.

Just picked up around 250g from the first flush. Used the whole vile to inoculate 4 PF Tek cakes and one jar of liquid culture. No contaminations, no problems, just a very good product (Posted on 2/9/2022)
