Choosing the right strain for your environment is key to success.
Cold Blue Oyster requires a cold shock (near-freezing temps) to trigger fruiting.
Most other oyster varieties do not require this step.
For best results, use:
• Pasteurized straw
• Cottonseed hulls
• Other agricultural byproducts
They are one of the easiest mushrooms to grow at home.
Some varieties (like Pink Oyster) can fruit in as little as 7–10 days under ideal conditions.
Most varieties produce multiple flushes over time.
• Meaty and savory
• Slightly sweet
• Some varieties have seafood-like flavors
They are excellent sautéed, grilled, or used as a meat substitute.
They tolerate a wide range of conditions and colonize quickly, making them ideal for beginners.
• Specialty strains may take 4–6 weeks because they are made fresh to order
• Faster colonization
• Stronger yields
• Lower contamination rates
Fresh spawn performs better — especially for growers selling to markets or restaurants.
• Produced fresh (not sitting on a shelf)
• Selected for strong performance and yield
• Used by home growers and commercial producers alike
I’m many years customer!
This is my first time growing mushrooms and this oyster spawn did not disappoint! I picked the Aspen Oyster since I am growing on poplar tree substrate. The spawn has a nice anise smell and has taken over the sawdust substrate well. I’m curious to see how my logs will turn out, but the product itself was healthy and arrived quickly. Thank you!
Thank you for the quick delivery. Products received and substrate inoculated immediately. Just waiting for my buckets to come alive.
Couldn’t have been happier! Shipped quick and in great shape. I used it to make a big straw log. Wish you had the big long bags to make them with. PoHu is my favorite oyster to grow, Mushroom Mountain is my favorite place to order from. Always fast, in good shape and you don’t mind me asking questions. Thanks!
Hey Mark! Thanks for he feedback. We are actually working on the long bags, and they will be customizable for no extra fee. You tell us the length, and we will make them the size you need. Give me about a month, and I will send you the link to the product.
I ordered 3 5# bags of oyster spawn, warm blue, phoenix and pink. Used hardwood heating pellets and alfalfa pellets as substrate in 10 gallon totes. They are fruiting after just 2 weeks. Yippee!
Love all your product and your movement!
Everything that I've ordered from Mushroom Mountain met my expectations; inoculation tools, mycelium blocks, and fruiting blocks! Thank you!
It was really dry and hard. Not sure if it'll grow. But I'll give it a try.
Hey Darren! Oyster mycelium is very healthy and strong. It should do wonderfully in your grow. Please let me know if you have any issues with it, I can help troubleshoot. Thank you, Olga
Good
Mycelium was heavily weighted towards the top of the sawdust with little to no visible mycelium about half way down. It did end up growing fine in straw, but about a week slower than a properly populated bag would have allowed.
Hey Cal! Which of the spawn looked like that? Can you send me photos please? I would like to resolve this for you. olga@mushroommountain.com. Thanks, Olga
Very healthy growth
I bought these to help break down all the fallen trees from Hurricane Helene. I was surprised to see these oyster mushrooms popping up so quickly and spreading all throughout stacks of wood away from where the block was buried after several days of rain.
Oh yay! I would love to see some photos. My pink oyster mycoGarden just produced as well. it was quite a pleasant surprise seeing the pink mushrooms against the green tomato plant background. It is making me constantly walk by my garden out of curiosity, just in case I see some other mushrooms pop up.
One is still in in cold storage , to be put into operation a week or two, looking good
I did ! It looks awesome! I don't know why I got the Kings I guess I thought you could grow them on logs. Inhale grown some mushrooms in tubs but im not really set up for it,and I would need some masters mix. I think I'm just going to try and let them fruit in the bag although they do sound very tasty !
Speedy delivery! Cant wait to see what happens with my little beds!
Fast growing and so far so good. Will be ordering other species.
The oyster spawn came well packaged. It was moist, and easy to spread.
Thanks for the fast shipping and the great spawn.
This order came quickly and the mushrooms are growing well despite me putting them in a suboptimal environment
I appreciate the 3bags of Sawdust spawn arriving quickly and in good condition. I would request Muchroom Mtn folks carefully inspect the sawdust as I have experienced lots of larger chips that plugged up my plunger and kept it from getting a full plug into the holes we drilled.i had to sift through the the other 2 packages to remove the chips before inoculating our logs. It was very time consuming and irritating.We will wait for the logs to produce to give a final review. Thanks folks.
Hey Tim. Would you please send me a picture of the larger pieces of sawdust? We do sift our sawdust, I am curious to see how large the pieces were, so I can get the issue resolved quickly. I appreciate you. olga@mushroommountain.com
As always, a great product.
Had some trouble with shipping with the first batch, but they made it good and the new spawn looks great. Can't wait to get started growing.
Product as described, fully colonized with mycelium. Now we wait and see.
I've ordered a couple times from y'all over the last couple years and each time has been great. This is my first time growing a block indoors, so I'm excited to see how it goes!
Tasty
Never received them or a response from company
Gosh. That is terrible. I am so sorry we dropped the ball on this. I will personally email you to rectify this issue.
I ordered for a class that starts this
week. Product looks fantastic. Loved literature that came with my order. I will be visiting in the Spring!
I refrigerated this until ready to mix with two 5-gallon buckets of straw that had been pasteurized with boiling, then cooled to room temperature. The buckets have holes drilled in the sides and I stack them and zip them into a large plastic garment bag, and by spritzing I maintain high humidity. The oyster mushrooms that grow through the holes are delicious! Best of all, after the crop is done I dump the straw in a shady moist corner of my garden and soon, mid winter, despite freezing temperatures the oyster mushrooms pop up again, ready for us to eat with no competition from the chipmunks that stay home in their burrows on cold days.
Grew some in a bag with coffee and some hay.Then I put the rest inside 3 bales of wheat straw watered and covered . Got 9 pounds the first picking. First time grower also.
