Our pink oyster (Pleurotus djamor) fruiting block features a tropical strain that produces beautiful clusters of mushrooms with light pink to deep pinkish-red caps, depending on lighting conditions. They are succulent and savory, have a denser texture than other oyster varieties, and their intense color and rich umami flavor make them a popular meat substitute.
Pink oyster mushrooms thrive in warmer temperatures and are great for beginners as they are reliable producers. They are also one of the easiest blocks to get subsequent fruitings and, if kept in the right conditions, should reliably produce a second flush or more!
Upon receiving your kit:
Remove kit 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 until you are ready to grow your fruiting block!

For the majority of mushroom species, all that is needed to initiate fruiting (or begin the growth cycle) is a change in environmental conditions -- specifically humidity, light, temperature, and changes to oxygen and CO2 levels.
For best results:
We recommend growing your pink oyster block in a fruiting chamber (like a monotub or martha tent) as a controlled environment will decrease the risk of contamination and increase the chances of success.
Creating optimal conditions:
The environmental parameters for pink oyster mushrooms can be found on this page under "Temp, Humidity & CO2 guide" and on page 6 of our fruiting block instruction booklet.
Preparing your block:
Tightly fold excess plastic back and place the block face up.
How to initiate fruiting:
- Slice bag with a single diagonal line or with an X.
- Pink oyster mushrooms can be top or side fruited.
Special considerations:
- Pink oyster fruiting blocks are not cold tolerant and will die if refrigerated.
- Pink oyster mushrooms will not grow in temperatures below 65 degrees.
- Exposing pink oyster mushrooms to more light will produce a more pigmented cap.
- Color will transfer to lighter colored mushrooms when grown or packaged together.
Harvesting your mushrooms:
Harvest pink oyster mushrooms right before the caps flatten out, removing entire cluster with care to minimize breaking. Pink oyster mushrooms have a short shelf life.
Growing different blocks together:
With some compromise, many different species of mushrooms can be grown together in a fruiting chamber. First, consider the temperature range of the mushrooms you desire to grow, and second, the CO2 sensitivity. Humidity ranges overlap for the majority of species. We encourage you to experiment with many different groupings!
Troubleshooting:
Having issues with unusual growth, stunted growth, or no growth at all? Refer to pages 16-18 in our fruiting block instruction booklet.

Temperature 70-80°F | 21-26°C Humidity (Phase 1: Primordia) 95-100% Humidity (Phase 2: Fruitbody) 85-95% CO2 Sensitivity (Phase 1: Primordia) 500-1,000 ppm CO2 Sensitivity (Phase 2: Fruitbody) 500-1,000 ppm - Primordia - The earliest recognizable stage of fruitbody development. Also known as “baby mushrooms” or “mushroom pins.”
- Fruitbody - A fully grown mushroom, the reproductive structure of the organism in which the spores are produced.
- 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.
-
Do not refrigerate pink oyster kits. If you are not ready to use your pink oyster fruiting block immediately, store at room temperature, out of direct sunlight, for up to 3 months.

The classic North Spore recipe is to chop the pink oyster mushrooms and sauté them in a heavy pan on medium heat with butter, garlic, and loads of fresh thyme and rosemary (or whatever other herbs you happen to have on hand!). Cook until the mushrooms have released their liquid, then continue cooking until that liquid has cooked off and the mushrooms begin to brown. This can take from 20-30 minutes. Deglaze your pan with a splash of white wine, reduce once more, and finish with a touch of heavy cream. Season generously with salt.
-
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.
Mushrooms grow spores as they develop. This is a natural means of reproduction. This is when people with allergies or compromised immune systems may want to consider putting fruiting mushroom kits outdoors or in a well-ventilated area. Spores in mushrooms sometimes cause respiratory irritation. In rare cases, spores may also cause irritation for some non-allergic or non-immunocompromised mushroom growers. If you are one of them, it is recommended to reduce the overall spore load by harvesting mushrooms while they are still in their younger growth stages.

Buy this block!
I had my first flush less than four days after I put the block in my Martha Tent! Pink Oyster Mushrooms happen to be one of my family's favorite mushrooms and, as a tropical species, we'd been struggling to get our inoculated batches to thrive up here in Northern Vermont, especially through the winter. Our friends at North Spore made sure we were set up for success. This fruiting block has become a standard part of our growing operation since the first time we bought one.


Easy and delicious
This block was great. It was my first time growing mushrooms and it was super easy. We got 2 meals out of the yield. I highly recommend!

So fun to grow with my toddler!
Super easy to grow and quick! Grew pink oyster mushrooms with my 4 year old and she was so excited. She told everyone she met “we are growing pink mushrooms in our shower”. Fun winter project and tasty too.

Fast producer
It grew very quick cant wait to cook them. This the first flush robust...

Aggressive Pinkies
By far the quickest growing strain I have seen. Quite aggressive even at an avg. temp of 65° (that's 10° below what is recommended). Another successful experience with North Spore. I am sure this block will produce multiple flushes and then easily be transfered to new substrate successfully. Experiment = Experience
Gorgeous mushrooms
Shipping was fast and all the directions, tips, and troubleshooting info makes these fruiting blocks a no brainer. They grew super fast, and yielded beautiful mushrooms that were so fun to watch grow!

FAST!
I have had several pink oyster kits, which have always been my favorite, as they produce so fast and abundantly. My last attempt was the fruiting block for my Boom Room, and they continue to amaze me. The pictures below were taken on day 2,3,4, and harvested on day six after arrival, weighing slightly over 1 1/2 pounds on the first flush. With previous experiences with the pinks, I'm expecting the second flush within 7-10 days, and I have had up to four flushes off of a single kit, then broken up into lime sterilized straw in an old laundry basket, and three more larger flushes before I manage to oversaturate the straw and lose them. I am a rookie, but for my investment, the Pinks give more production in less time,(meaning less maintenance, aka labor) and I am enjoying lots of delicious, healthy mushrooms!

Wow
This fruiting block was amazing. The pink oysters grew so fast. Doubling in size in under a day was the norm. We harvested the first flush in under a week. Second flush underway. Amazing flavor with simple butter, garlic, thyme, salt, pepper recipe. Perfect paired with our sous vide tri tip. Will definitely get these again.
