Organic Golden Oyster Mushroom Grain Spawn
€26,95
Our USDA-certified golden oyster (Pleurotus citrinopileatus) grain spawn feature a tropical strain that produces beautiful clusters of bright, jaw-droppingly beautiful mushrooms with medium yellow caps and long delicate stems. A favorite at farmer's markets, they have a mild nutty flavor and aroma reminiscent of cashews. Golden oysters are great for beginners and are reliable indoor year-round producers. If kept in the right conditions, they will yield substantial first, second, and even third harvests (making them an ideal commercial variety!) As a tropical strain, they thrive with higher humidity.
Golden oyster grain spawn can be used for indoor cultivation year round. When used for outdoor cultivation, golden oysters are generally not cold tolerant and fruit prolifically in summer months.
Recommended use:
- Golden 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. Golden 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!

Temp, Humidity & CO2 guide
| Temperature | 65-80°F | 18-26°C |
| Humidity (Phase 1: Primordia) | 98-100% |
| Humidity (Phase 2: Fruitbody) | 88-95% |

- 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.
Indoor cultivation
Oyster mushroom grain spawn can be mixed into sterilized or lime pasteurized substrates including but not limited to hardwood sawdust, straw, and coffee grounds.
Note: Grain spawn must be mixed with bulk substrate before you can fruit it. If you are new to growing mushrooms, we recommend purchasing a book on mushroom cultivation.

Outdoor cultivation
Oyster 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.
Storing
If you don't plan to use immediately, you can refrigerate your spawn for up to 4 months.
Cooking
Golden oyster mushrooms develop a cashew-like flavor when cooked to a slightly crispy texture. They 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.
Ingredients
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.
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.

Process went well thanks to all the info on the North Spore website a ND YouTube channel.
Thank you for sharing your experience, Cindy! What an amazing harvest.
C
Followed instructions from North Spore learning center and have an awesome fruiting coming on! Great stuff!
Your grow looks amazing, Curt! Please reach out if you ever need anything.

First time ever growing mushrooms in our garden this winter (very low lech) - I inoculated aspen woodchips in buckets in January - a nice layer of mycelium had formed, but no mushrooms for 2 months. I transferred the woodchips into our 20 gal fabric grow bags on top of garden soil (to use as compost) and about 2 weeks later we harvested our first flush of Golden oysters!!! They are not as vigorous as blue oyster (5 flushes out of each bucket),a lot more delicate, but so delicious 😁
We really appreciate you taking the time to share your experience, Kay! Please reach out if you ever need anything.

Seemed healthy substrate ruined everything.
We are really sorry and understand how frustrating this experience has been. Somebody from our team is reaching out to you via email now to assist you with the issue.

For 2-3 years, I used North Spore products successfully and gratefully, mostly oyster mushroom grain spawn. But for 2 years now, everything I've purchased from N Spore--the Boom Room II and grain spawn--has failed disasterously. The BoomRoomII had fundamental design flaws, the instructions were not simply bad, but disasterous--too many problems to even list here, let alone describe; and the last 2 oyster mushroom grain spawn bags grew black mold like I've never seen before anywhere, and not because I did anything wrong, as I purchased grain spawn from another company that grew perfectly, as N Spore's grain spawn with me in the past, all via the identical methods. The only reason I'm even writing this review--since I told them if they refunded my last grainspawn purchase they'd never hear from me again, and I promptly **unsubscribed** from their email list--is because despite unsubscribing and a 2 year pattern of terrible products and services (except they did immediately refund my last purchase, which tells me I wasn't the only one with that problem), THEY SENT ME AN EMAIL ASKING FOR THIS REVIEW. Talk about stupid. You **never** send such an email to an unsatisfied customer. I shouldn't have had to unsubscribe, they should have done that for me proactively. My best guess is that the company was bought out by people who have no idea what they're doing, or the original mycologists, if that's what they were, just never realized they aren't business people and so expanded the business having no clue what they were doing. But whatever happened, the company tanked about 2 years ago--REALLY BADLY--and I can't believe they're still in business. Where do they get the money to buy these fake 5 star reviews? They haven't earned them any time recently. And NS, don't worry if you delete and never post this review, as I'll share it with deserving people elsewhere, where it will get the attention it--and all who read it--deserve. The crash of North Spore has been a significant loss for me, but thank god, there are competitors offering legitimate products (not that NS is any longer real competition).

My third time ordering from here. This time it wasn't to give as a gift. Love that they give you guides to grow. Can't wait for my mushrooms to fruit!
We're so glad you're enjoying the experience! Thanks for the great review.
E
Absolutely fantastic! My grandchildren love picking the mushrooms.
Thanks for sharing, Erik! We're so happy you and your grandchildren are enjoying the experience.

This is a nice eye popping mushroom for the farmers markets. Not my personal favorite to eat but customers like it because of that bright color, so it almost always sells. And of course, with all Norse four items. They are healthy and love to grow.
B
The mycelium seem to be spreading well so far :)

Very colonized, no contam

I have very little experience with mushroom cultivation. Last year I purchased these to attempt to grow them in five gallon buckets with straw as the substrate. I saw many videos on YouTube that complicated the process, but I decided to just wing it. It worked out great and I received three good sized flushes. Although I will say, each flush became progressively smaller, but I think that is normal.
Would definitely recommend to the complete beginner!
Thanks for your review, Daisy! Congrats on your harvest.
J
The strain was very aggressive
We're so glad things are growing well for you, John! Please reach out if you ever need anything.

The spawn was fairly aggressive and has grown several bags already. It's performed exactly as you'd want. I appreciate that this spawn comes fully colonized. It was READY
Thanks for the great review, David! We're so glad everything is working out for you.
D
This batch spawn is growing awesone!!!

Waiting for first flush

So far, so good!

First time growing Golden great strain and fast colonizer!
S
Did them in straw 5# buckets. The first yield was an amazing 1.3pounds! And that was.just three holes.
D
Awesome spawn
J
Love the golden oysters
Thanks for the great review, Joe! Golden oyster is one of our favorite species, too!
M
Great! Fast colonizers! Great yields, multiple flushes, repeat customer! Customer service had been great since first purchase years ago. Highly recommend for people without the time to do their own
T
Easy to grow, and they grew fast….
Dumped the used bucket straw outside, and got more mushrooms!! Just bought another bag of spawn to grow some more. Great product.
O
Fantastic product with delicious results. My only issue with the product as a whole is the lot/generation info sticker has been put above the filter patch on each bag I've bought, which makes resealing these bags very difficult. I do not have the need or ability to grow 100lbs worth of fruiting bags in one go so there is a need to be able to reseal the spawn bags when i'm done with a batch of fruiting bags so it can be in good shape a few weeks down the line when i'm ready to start another batch.
F
Great for inoculation buckets.
T
These were just two photos from my harvest two weeks ago! I had a total of 5 cardboard berry boxes taken out of my grow tent. The largest oyster cluster I have grown so far has been a Golden Oyster that was 14.3 oz. They are so beautiful and everyone loves the Goldens! I just bought 3 more bags of Golden Grain Spawn! Cant wait to make more buckets!!!
J
I was very happy with my purchase. Mushrooms grew very fast and kept on growing. On my second flush now. Hoping for more!!
