Our USDA-certified organic Pink Oyster (Pleurotus djamor) grain spawn features a tropical strain that produces beautiful clusters of light pink to deep pinkish-red caps that are a favorite at farmers' markets. They are succulent and savory, and have a denser texture than other oyster varieties. They are great for beginners and are reliable indoor year-round producers. And, if kept in the right conditions, they will yield substantial first, second, and even third harvests (making them an ideal commercial variety!) Note that the shelf life of pink oysters is shorter than other oyster varieties. As a tropical strain, they also thrive with higher humidity.
Pink oyster grain spawn can be used for indoor cultivation year round. When used for outdoor cultivation, pink oysters are not cold tolerant and fruit prolifically in summer months.
- Pink oyster grain spawn can be used for indoor production using sawdust or straw or outdoor production using straw or wood chips.
- Do not use grain spawn for log inoculation.
- This is not a mushroom grow kit. Pink oyster grain spawn must be combined with a substrate in order to fruit.
Upon receiving your spawn:
Remove it from the shipping box as soon as possible. Then, unfold the top of the bag, making room for air space. It's also important to check and confirm that the filter patch is not obstructed. This will help the organism breathe and continue to thrive!

Pink oyster grain spawn can be spread in chopped straw or wood chips as shown in the video below! Making outdoor beds is one of the easiest methods for growing any type of oyster mushroom.

Be sure to use clean, untreated products when making outdoor beds.
Do not refrigerate pink oyster spawn. If you don't plan to use immediately, you can store your spawn at room temperature, out of direct sunlight, for up to one month.
Pink oysters mushrooms can easily replace button mushrooms in most recipes and pair well with many cuisines and flavors. Like all oyster mushrooms, they retain water and may develop a viscous texture when undercooked. If you prefer a firm or dryer texture, continue to cook them until their liquid has reduced and cooked off and they begin to brown.
Our grain spawn is USDA certified organic and made using organic cultures from our own culture bank. It contains a blend of locally sourced, organic, and non-GMO ingredients from farms in New England and North America.
If you’re going to consume home-grown mushrooms, make sure to cook your fresh mushrooms thoroughly with heat. If it is your first time eating this species, it is best to start with a small amount to check for allergies, even if cooked.

I am a newbie to the world of mushrooms. Ordered the pink oyster grains, grew them in two 5 gallons buckets, hung them under a tree, after colonization, and pinning First harvest 7lbs, second harvest approximately 2 lbs. Beautiful mushrooms, looked like sea corals, and tasted like chicken breast. AMAZING!! afterward, i removed the straws and placed them under a tree, hoping to get another harvest. Unfortunately, my hens ate all the grains. The pictures below, I placed a papaya, the size of a cantaloupe next to the mushroom for perspective. Thank you North Spore for the incredible products, and a wonderful experience.
Seeing BEAUTIFUL mushrooms after only 10 days!
I live in Austin TX and I planted the organic grain spawn in straw and put it in two old shopping carts. After only 10 days I'm seeing beautiful pink oyster mushrooms everywhere! They're peeking through on all sides and even through the bottom of the carts. I'm so freaking excited! Now I'm looking all over for old metal baskets to grow mushrooms in. YAY!
Cannot Say Enough
We inoculated our high tunnel with this spore at the beginning of the year (Zone 8) and still: these pink beauties pop amongst our peppers, okra, and eggplant. Fantastic results! They really do not mind the heat, at all.
Harvested in 3 weeks under ideal conditions
I layered one bag of grain spawn with composted leaf humus and straw in a shaded spot under a pine tree in late June in Ohio. Precisely three weeks later I harvested the first flush weighing 5.5 lbs. The weather was ideal with regular and above-average rainfall.
