Grain spawn is a little known secret weapon of the world of mushroom cultivation. It’s made from sterilised grains that have been inoculated with a live mycelium culture.
Grain spawn contains a lot of energy for the mycelium to consume. It’s a bit like rocket fuel for mushrooms. It’ll take off like wildfire once added to your bulk substrate.
Mother Nature works her magic using spores but in a controlled environment you need to tip the scales in your favour by using clean high-quality grain spawn so you are doing your best to ensure success.

The pink oyster mushroom (pleurotus djamor) is a strikingly unforgettable, edible fungi in the family Pleurotaceae. Growing well in warm climates has lead this mushroom to become widely cultivated in Asia. Its vibrant, bivalve-like fruiting bodies are attractive while developing but lose colour quickly upon maturity or when cooked.
Pink oyster mushrooms have a much, richer and deeper flavour than its button mushroom counterparts that we’re well accustomed to finding in the supermarket.
The pink oyster mushroom is chewier and ideal for adding to a stir-fry or soup for that extra umami kick. Try crumbing and frying them for an amazing faux-calamari or even slow roasting in the oven for an hour or two with your favourite seasonings and a lashing of olive oil to make some ridiculously tasty, low-carb mushroom chips.
Pink oyster mushrooms will grow on a wide range of materials including sugar cane mulch, straw, hardwood, paper and coffee grounds.
For beginners we recommend starting with straw or chopped sugar cane mulch. Supplementation can be added in the form of coffee grounds or bran but will increase the chances of contamination.
Pink oyster mushrooms are considered to be a side-fruiting mushroom compared to the king oyster or button mushroom which are top-fruiting mushrooms.
Save on filter patch grow bags when you spend over $45 on grain spawn or grow kits.
Pink oyster mushroom mycelium is incredibly vigorous. Initially it is finer in appearance and structure than white oyster. Pink oyster mycelium is slightly translucent and will turn more opaque as it matures.
The mature spawn will often begin to turn pink within days of colonisation, this is indicative of it preparing to fruit. The maturing mycelium will produce yellow liquid metabolites which are a completely normal byproduct.
Any primordia which has formed prematurely, or in-vitro can be removed prior to using the spawn as usual.
Pink oyster mushrooms will colonise both grain spawn and substrates very quickly. Full colonisation can often expected within 7 – 10 days. Store between 23 – 28 degrees Celsius (73 – 85 F) for optimum colonisation speeds.
Expose the fully colonised substrate to fresh air ad humidity to trigger the formation of primordia.
No special are requirements to trigger pinning on pink oyster mushrooms. These will begin pinning on their own if left unattended and should be opened once fully colonised.
Fruit pink oyster mushrooms between 20 – 30 degrees Celsius. However they will tolerate temperatures outside this range. Maintain humidity over 85% for best results. Harvest mushrooms before caps turn upwards and release spores.
Experienced mushroom cultivators will often produce their own grain spawn to reduce the cost of growing mushrooms. Grain spawn can be produced in small batches without the need for purchasing expensive equipment. Learn more about making grain spawn in our guide.
Humidity can be managed through a diligent misting and fanning regime, however the introduction of a humidifier and humidity controller can help automate the process and ensure consistency.
Adding a 6L humidifier and controller to a greenhouse with the addition of a USB fan is a quick and easy way to make a low cost fruiting chamber that delivers excellent results.
Mushrooms require humidity to grow. We recommend using a mini-greenhouse. Spraying the inside walls of the greenhouse will help raise humidity. A cheap humidifier can used to automate the process.
It’s important to ensure that the grow kit has fresh air exchange. Mushrooms produce carbon dioxide and will grow long and leggy if they require more oxygen.

Alternatively you can build a Shotgun Fruiting Chamber (SGFC) from a few common items found easily in your local hardware store.
