💙 Blue Shimeji Oyster Mushroom Spawn Guide (Pleurotus ostreatus)

Ready to build your own mushroom blocks from scratch? The Blue Shimeji (Pleurotus ostreatus) has been a massive hit and a staple among Aussie growers for the last 10 years! This super-fast-growing and incredibly tasty commercial strain is unique: while the individual mushroom caps grow much smaller than a standard oyster, they form extremely dense, tightly packed clusters that result in massive overall yields.

🌾 Recommended Substrates Like most Oysters, the Blue Shimeji is an aggressive grower and not a picky eater! You can successfully inoculate:

• Straw or Sugarcane Mulch

• Hardwood sawdust or wood pellets

• Paper pellets or cardboard

• Agricultural wastes (corn cobs, cotton wastes, coffee grounds, leaves, and sunflower husks/stalks)

🛠️ How to Prepare Your Substrate (Video Guides) To use this spawn, you will need to pasteurise your chosen substrate first to give the mushroom mycelium a head start over any competing molds. You can use any of these easy methods! Check out our step-by-step video tutorials for the best ways to prep your bulk substrate:

🧫 Incubation (Colonizing Your Block) Once you have mixed your spawn into your prepared substrate and sealed your bags, it is time to let the mycelium take over!

• Temperature: Store your inoculated bags in a clean, dark space with stable temperatures between 16-20°C.

• Fresh Air: The growing mycelium needs to breathe! Ensure your incubation room has good ventilation, aiming for ideally one room air change per hour.

• The Goal: Leave the bags to incubate until the substrate turns completely white with mycelium. Once fully colonized, it is ready to fruit!

🌤️ Best Fruiting Environment

• Temperature: This is a fantastic winter strain! Once fully colonized and ready to fruit, it thrives in a cooler temperature range of 10-24°C. The cooler the temperature, the deeper the steel-blue colour will be!

• Light: Place your fully white block somewhere with enough natural, indirect light to read a book by.

• Humidity: When you cut your fruiting holes, keep the humidity high (70-80%+) by misting the area around the cuts 1 to 3 times a day.

• Fresh Air: Mushrooms “exhale” CO2 as they grow! To ensure you get beautiful, dense clusters instead of long, stringy stems, you need excellent fresh air exchange. Aim for 6-8+ room air changes per hour in your fruiting space.

🍄 Tips & Harvesting

• Inoculation Rate: We generally recommend mixing your spawn into your prepared bulk substrate at a rate of 10% to 20% by weight. The more spawn you use, the faster it colonizes!

• Bite-Sized but Heavy: Don’t wait for the caps to get huge! The Blue Shimeji is genetically meant to produce small caps. Focus on the edges of the caps rather than the overall size to know when they are ready.

• When to pick: Harvest the entire cluster at once when the edges of the largest caps in the bunch are still slightly curled downwards. As soon as they start pointing up and flattening out completely, they are about to drop spores!
