Organic Golden Oyster Mushroom Grow Kit Fruiting Block
|Grow speed||1 to 2 weeks|
|Shelf life||6 months (refrigerated)|
|Kit dimensions||6in H x 9in W x 6in D|
|Kit weight||5 lbs|
Our golden oyster (Pleurotus citrinopileatus) fruiting block features a tropical strain that produces beautiful clusters of bright, jaw-droppingly beautiful mushrooms with medium yellow caps and long stems. When cooked, they have a mild nutty flavor and aroma reminiscent of cashews that pairs well with most dishes.
Golden oyster mushrooms are great for beginners as they are reliable producers and tend to grow large flushes. 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!
Scroll down for guides on growing, storage, cooking, and more.
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 golden 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 golden oyster mushrooms can be found on this page under "Temp, Humidity & CO2 guide" and on page 5 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.
- Golden oyster mushrooms can be top or side fruited.
- Golden oyster mushrooms will not grow in temperatures below 65 degrees.
- Exposing golden oyster mushrooms to more light will produce a more pigmented cap.
- Golden oyster mushroom caps and stems are delicate and prone to breaking; handle with care.
Harvesting your mushrooms:
Harvest golden oyster mushrooms right before the caps flatten out, removing entire cluster with care to minimize breaking. Golden 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!
Having issues with unusual growth, stunted growth, or no growth at all? Refer to pages 16-18 in our fruiting block instruction booklet.
Temperature 65-80°F | 18-26°C Humidity (Phase 1: Primordia) 98-100% Humidity (Phase 2: Fruitbody) 88-95% CO2 Sensitivity (Phase 1: Primordia) <1,000 ppm CO2 Sensitivity (Phase 2: Fruitbody) <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.
If you don't plan to use immediately, you can refrigerate your block for up to 6 months.
The classic North Spore recipe is to slice up 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. Deglaze your pan with a splash of white wine, reduce once more, and finish with a touch of heavy cream. Season generously with salt.
Like all Oyster mushrooms, they retain water and may develop a viscous texture when under-cooked. If you prefer a firm or dryer texture, continue to cook Oysters until their liquid has reduced and cooked off and they begin to brown.
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.

North spore block arrived quick and ready to fruit. Placed it in my boom room and was able to get 2 large flushes from the block. Very tasty!
Thanks for sharing, Shane! We're so glad to hear you're enjoying the experience.
Ideal for simplicity and productivity, especially for beginners
Top quality experience- highly recommend. Highly productive, quick to fruit, and a perfect beginner strain. I have intermediate experience with black kings, which are spectacular but take more “dialing in” for fruiting conditions. These were so easy and productive that they will be part of my regular rotation. A very delicious strain on pizza and great pairing with wild rice bowls. 2 solid flushes so far with no contamination and a third possible ~209/240 grams in the first two flushes Spore production is significant allowing for a great spore print - but I would not recommend growing them outside of a fruiting chamber (in an open indoor space like a counter) due to high spore production, fruiting chamber is a must.
Easy to grow and delicious
So fun and easy to grow. A more delicate texture and flavor than some other oyster varieties. Will definitely grow again.
Thanks for sharing, Paula! We appreciate you taking the time to share your experience.
A Really Active Block!
Not sure if it was just my particular block, but while it took a little longer to pin then expected (my pink oyster pinned only 3 days after activating, so my expectations are maybe very high), but once they started pinning, i barely need to wait a week after I harvest them for them to go again. The first time it was only a couple days before the 2nd pinning, and now it's been about a week and its already beginning to pin again! I guess it helps that it's just super rainy and humid in New England right now as well, but still!
We're so glad you're enjoying the golden oyster kit, Elliot! Please reach out if you ever need anything.
Good tasting mushrooms
I got a decent size first batch, around 14 oz, however I did not get a second batch.
Very quick and easy to grow. Taste is incredible, my wife hates mushrooms but loved these.
Love the Golden Oysters!
Love these delicious oysters! 2.5 flushes out of one block! Love the Golden Oysters!
This was probably the second tastiest to the chestnut and was easy to grow. Had 4 flushes coming from this one block with the first two big ones and consecutively getting smaller with the last two.
Grows really fast
They started growing like crazy after I put it in my grow house! I have harvested 2 flushes and already have 2 more growing right now!
Beautiful mushroom, wish I could get the pink, blue, and snow oysters to produce at the same time to make a flower arrangement, except it would look too good to eat! I have grown kits and blocks before, with up to 3 flushes before, but when flushes start to get small, plant them in straw buckets and they keep going, and going and going! I have even salvaged mycelium from my buckets after several flushes and placed in fresh straw, and they keep going! (even in the front yard!)
