About golden oyster mushrooms
Brighten your growing experience with our Golden Oyster (Pleurotus citrinopileatus) grow block, designed to produce breathtaking clusters of vibrant, sunny-yellow mushrooms with elegant, long stems. These tropical beauties offer a mild, nutty flavor and a delicate aroma reminiscent of cashews, making them a delightful addition to any dish.
Perfect for beginners, golden oyster mushrooms are reliable producers known for yielding impressive flushes. They’re also among the easiest varieties to cultivate for multiple harvests—just maintain proper growing conditions, and enjoy a second flush (or more!) of these stunning, flavorful mushrooms.

Upon receiving your kit
Take the kit out of the shipping box right away. Next, unfold the top of the bag to create space for airflow. It's important to make sure the filter patch is clear and unobstructed so allow adequate airflow. This ensures the mushroom's mycelium can breathe and stay healthy until you're ready to start growing your fruiting block.

Growing instructions
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!

Temp, humidity, & CO2 guide
Temperature:
Humidity (Phase 1: Primordia)
Humidity (Phase 2: Fruitbody)
CO2 Sensitivity (Phase 1: Primordia)
CO2 Sensitivity (Phase 2: Fruitbody)
60 - 70°F | 15 - 21°C
98 - 100%
88 - 95%
500 - 1,000 ppm
<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.
Storing
If you don't plan to use immediately, you can refrigerate your block for up to 6 months.
Cooking
"5 of the Best Chestnut Mushroom Recipes"
For those who enjoy the distinct nutty flavor of chestnut mushrooms, we recommend frying them up with butter and garlic or adding them to your favorite creamy soup or pasta dish. As with other mushrooms, chestnut mushrooms require thorough cooking. However, given their lower moisture content, they do not require “sweating” in the pan.
Cautions & considerations
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.
