The Blue Oyster mushroom (Pleurotus columbinus) is a fast‑growing, cold‑tolerant oyster variety ideal for both beginner and advanced mushroom growers.
It performs well on a wide range of substrates and produces dense clusters of blue‑grey caps with excellent flavour and texture.
Substrates: Hardwood sawdust, coco coir, straw, coffee grounds, cardboard and other cellulose‑rich mixes
Colonisation temperature: 20°C – 24°C
Pinning temperature: 15°C – 24°C
Pinning humidity: Around 95%
Fruiting temperature: 15°C – 24°C
Fruiting humidity: 85% – 90%
10 ml liquid culture syringe containing vigorous, living mycelium of Blue Oyster mushroom (Pleurotus columbinus)
Sterile alcohol wipe
18G sterile needle for inoculating your chosen substrate or mushroom grow kit
All components sealed in a secure zip‑lock bag for clean storage and transport
Blue Oyster liquid culture is a nutrient‑rich, sterilised solution made from distilled water with light malt extract, dextrose, and honey, formulated to feed and expand the mycelium.
This actively growing mycelium functions like a mushroom “seed,” allowing you to quickly and evenly inoculate grain spawn, bulk substrate, or ready‑made mushroom grow kits for reliable colonisation.
For best performance, use your Blue Oyster liquid culture as soon as possible to ensure maximum freshness, vitality, and yield.
If immediate use is not possible, store the syringe in the refrigerator, where it can typically be kept for up to 3 months while maintaining good viability.
All liquid cultures are routinely tested on agar and grain to confirm purity, strong growth, and consistent strain characteristics.
Each batch is prepared fresh to order in a sterile laboratory environment, using a laminar flow hood to deliver clean, contamination‑free cultures suitable for serious mushroom cultivation.
