Pearl Oyster Mushroom (Native UK Strain) Liquid Culture

(Pleurotus ostreatus)

Locally foraged and cloned from the wild, this Pearl Oyster culture brings the resilience and vigour of nature into your grow space. Known for its elegant, pale caps and fast colonisation, Pleurotus ostreatus is one of the most beginner-friendly and rewarding mushrooms to grow. It’s perfect for both culinary use and sustainability-focused cultivation.

This culture was isolated and expanded in sterile lab conditions, then suspended in a nutrient-rich solution ideal for a wide range of substrates. Whether you’re growing for the kitchen, the farmers market, or composting benefits, Pearl Oyster is a true all-rounder.

Features:

  • 1x 10ml of high-quality, actively growing culture
  • 1x sterile needle
  • Tested to ensure only mushroom mycelium is present
  • Wild clone.
  • Ideal for straw, hardwood sawdust, logs, or supplemented substrates
  • Suitable for expansion to grain, agar, or other media

Suitable Substrates:

  • Hardwood sawdust
  • Enriched sawdust blocks
  • Sterilized wood chips or logs
  • Pasteurised straw

How to Use:

  1. Shake Before Use
    Gently shake the syringe to evenly distribute the mycelium throughout the liquid.

  2. Work Sterile
    Ensure a clean work environment. Use a still air box or laminar flow hood, and sanitize all surfaces, tools, and gloves with 70% isopropyl alcohol.

  3. Inoculate Substrate
    Inject 1–2 ml of liquid culture into your sterile substrate. Hardwood sawdust or a supplemented sawdust mix works best. Use a sterile needle and injection port for best results.

  4. Incubate
    Keep inoculated containers in the dark at 20–26°C (68–79°F). Colonization is typically rapid. Expect full colonisation in 1–2 weeks.

  5. Introduce to Fruiting Conditions
    Move to a fruiting chamber with high humidity, fresh air exchange, and indirect light. Pearl Oysters are fast to fruit and thrive in cooler to moderate temperatures (13–21°C / 55–70°F).

Store under 5°C. Refrigerate.

Use within 3 months for best results

FAQs


Mushroom tinctures are concentrated liquid extracts made from mushrooms, typically using alcohol and/or water to extract beneficial compounds.

Most people take tinctures by placing a few drops under the tongue or mixing them into water, tea, coffee, or smoothies. Follow the recommended dosage on the bottle.

Dosage varies by tincture type and individual needs. The recommended daily dose is 1-2 droppers (1-2 ml) per day. That’s 1-2 whole pipettes.

It depends on the type of mushroom:

  • Chaga: Anytime for immune support.
  • Lion’s Mane: Morning or midday for focus and cognitive support.
  • Reishi: Evening for relaxation and sleep.
  • Cordyceps: Morning for energy and endurance.

Single extraction uses only alcohol or water.

Dual extraction (which we use) combines both, ensuring the full spectrum of beneficial compounds is extracted.

We don’t have the certification to be ‘organic’ (we aim to in the future) but that doesn’t mean we don’t put the upmost attention to our process and where we source our ingredients from. Our mushrooms are only grown with natural ingredients (such as hardwood sawdust and rye grain). Our tinctures are the same, containing only natural ingredients; water, organic grain ethanol and dried mushrooms.

Yes, our tinctures use alcohol as a preservative and to extract certain compounds. If you prefer, you can mix the tincture into hot tea to allow some of the alcohol to evaporate. All together our tinctures contain 35% alcohol. The whole bottle contains about 17.5ml of alcohol, that’s less than a standard shot at the pub.

Most people tolerate them well, but if you’re pregnant, nursing, on medications, or have a medical condition, consult your doctor before use.

Some mushrooms (like Reishi) may interact with blood thinners or immune-suppressing drugs. If you’re on medication, consult a healthcare professional before use.

Keep it in a cool, dark place. No need to refrigerate.

Properly stored tinctures last 2+ years due to the alcohol content.

Cloudiness or natural sediment in your tincture is completely normal — and actually a good sign. It often comes from beneficial compounds like polysaccharides, beta-glucans, and triterpenes, which are key active components in medicinal mushrooms. These compounds are not always fully soluble in alcohol or water, so they can settle or cause cloudiness over time. We avoid over-filtration to preserve the full-spectrum goodness. Just give your bottle a good shake before each use to evenly distribute the actives.


Rehydrate them in warm water for 20-30 minutes before cooking, or grind them into powder for soups and teas.

About 10g of dried mushrooms = 100g fresh (roughly a 10:1 ratio).

We offer dried (dehydrated) and dried and powdered.

Keep in an airtight container in a cool, dry place. Refrigeration can extend shelf life.

Properly stored, they last 1-2 years or longer if vacuum-sealed.


Liquid culture: Contains live mycelium, grows faster.

Spore syringe: Contains spores, takes longer to germinate.

Store spore syringes in a cool, dark place (refrigeration optional).

Keep liquid cultures in the fridge for 2-6 months.

Inject 1-2 ml of liquid culture into sterilized grain and incubate at the recommended temperature.

Most culinary and medicinal mushrooms are legal, but always check local laws regarding spore sales.

Yes, but they require sterile conditions for best success.
