Oyster Mushroom Spawn Trio

Blue-Grey-White Oyster Spawn – Choose Your Variety

Fast-colonizing, forgiving oysters perfect for beginners and pros. Select one (or all three) – all on similar substrates with heavy clusters:

• Blue Pearl (Pleurotus columbinus) – vivid blue-grey caps, cooler fruiter
• Grey Oyster (Spoppo sporeless, Pleurotus ostreatus) – metallic-grey, no spores/allergies
• Warm White Oyster (Pleurotus ostreatus) – classic white, heat-tolerant

All spawn is 100% contaminant-free, farm-tested, cold-shipped fresh, and fridge-stable up to 6 weeks.

Flavour Profiles

• Blue Pearl: crisp, subtly sweet with sea notes – great raw or lightly cooked
• Grey (Spoppo): deep earthy umami, like roasted veggies
• Warm White: mild, buttery with gentle garlic-cream

Spotlight: Grey Spoppo – Sporeless Advantage

Fruits reliably at 10–21°C, no spore mess/safety issues. Use 5–15% spawn rate (10–15% ideal on pasteurized substrate) for rapid colonization.

Quick Guide to the Others

• Blue Pearl: stunning blue-grey, best 13–20°C, delicate texture
• Warm White: heat-tolerant up to 30°C, side-fruiting clusters
