Shiitake Mix Sterilised Substrate Bag (80%-20%)

Ready-to-Use Sterilised Shiitake Mix Substrate

Available in 1kg, 2kg and 3kg bags.

Our Shiitake Mix is a pre-sterilised, ready-to-use substrate made for shiitake. It is a blend of 80% hardwood pellets and 20% soybean hulls, hydrated to field capacity so the moisture is right from day one. Made on the Sunshine Coast and used on our own farm.

Best For
Shiitake. Shiitake feeds mainly on wood and does not respond well to too much added nutrition, so this mix keeps the hardwood high and the supplement low. Our Master Mix is richer and better suited to other wood-loving species.

Good to Know
With less nitrogen than Master Mix, shiitake colonises more slowly, so patience pays off. Expect around 3 months of colonisation, with the block popcorning then changing colour as it matures. To trigger fruiting, cold shock the block for 12 to 24 hours in the fridge, then remove the bag completely before moving it to fruiting conditions.

Using Your Bag
Check your bag when it arrives. If the seal, filter patch or plastic looks damaged, get in touch before using it. Store it upright in a cool, dry spot out of direct sun, and don't stack more than 2 bags high or squash them, as pressure can damage the filter patch or the bag itself. For best results use it as soon as you can, and within 4 weeks.

Each bag comes sealed with a filter patch. Cut it open to inoculate with grain spawn or culture. You can make your own grain spawn with our sterilised millet grain spawn bags. Open it in a still air box or in front of a flow hood, as clean technique makes the biggest difference to your success rate. After inoculation, colonise somewhere with good airflow, out of direct sunlight and away from direct heat or cold (check your strain's ideal incubation temperature).
