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.
Pink oysters 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 outdoors using straw or wood chips. It is also ideal for growing in buckets.
- 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!

- CO2 sensitivity - When CO2 levels are too high, yields will decrease, stems will become long and stringy, caps will be small, and/or growth will halt.

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.
For our complete mushroom beds pamphlet, click here.
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 have grown pink oysters from kits and fruiting blocks several times before, and have NEVER been disappointed. The pink oyster has been the fastest and best producer that I have grown, with up to five or six flushes on a single block. This is my first attempt growing them from grain spawn. I started eight 2 1/2 gallon buckets per North Spores guide, four buckets one day, and the second a week later to space out my harvest, placed them in a dark closet, and had mushrooms popping out where the humidity and temperature was too low for proper growth. I placed three buckets in my boom room( 2 1/2 frosting buckets fit great, available from most grocery store bakeries, free!) and the rest in my cool basement. I almost immediately harvested three pounds from my boom room, and was cycling them with buckets in the basement, and had to harvest them too! They seem to produce whether conditions are ideal or not, and it's best if you check them every day, not every 2 or 3 days. My only complaint is that with a busy schedule and poor timing with the one day, mid week local farmers market, it's a little overwhelming to find a good home for all these delicious mushrooms, as even neighbors and friends get their fill! And Kudos to the North Spore team! This world would be a much better place if everyone followed their lead.
Your review made our day, James! Please reach out if you ever need anything.
The first batch didn't grow. North Spore was very helpful and replaced them with another batch which gave us a nice crop.
Thanks for sharing, Marvin! If you need help with anything, please reach out.
