Blue Oyster (Pleurotus ostreatus) is a fast substrate colonizer with a strong bluish-gray hue. It produces richly umami mushrooms with a soft, meaty texture that pairs well with most dishes. Oyster mushrooms are great for beginners because they colonize quickly and are reliable producers.
As our most productive oyster strain, blue oysters are reliable, cold-tolerant, and fruit prolifically in early spring or late fall. They are also ideal for commercial cultivation, especially when grown on straw.
Recommended use:
- Blue oyster sawdust spawn can be used for log projects and/or outdoor bed, container, and bucket projects.
- Blue oyster sawdust spawn must combined with a substrate (like straw) or used in log inoculation in order to fruit.
- If growing on logs, one bag of sawdust spawn will reliably inoculate up to 20 logs. (You can calculate how much you'll need here.)

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!

Blue oyster mushrooms
I inoculated a straw bale with blue oyster spawn. About 6 weeks later several mushrooms have popped out. We've had a couple good rains and I'm expecting a big flush, can't wait! I love the flavor of blue oysters.

Good stuff works well
Mushrooms are great
GREAT PRODUCT - If you are on the fence, just order it
This is a high quality product. Very professionally packaged and shipped. The information included was so helpful. I started later in the season than I wanted to, but I still was able to harvest until it got too cold! I am in zone 4, and I cannot wait to see what happens when it warms up. I wish I could FILL my gardens with as many of North Spore's product as could fit! ... Goals. :) If you are unsure, I recommend you just do it.

Mushrooms... I'm impressed.
I ordered Blue oyster and red wine cap sawdust spawn. We started with the wine cap. We divided it in half and started half in the house. It's been 4 weeks and as of yesterday we have wine cap mushrooms. I was a little doubtful to begin with but I am very impressed with the results.
Excellent production!
I made my first mushroom beds with these. Despite not being an expert and making a few mistakes these started producing today, just 3 months after I made the bed. I thought for sure my chickens were ruining it as they liked to dig holes in the wood chips and soak up the cool moisture underneath. Not the case!

Thanks so much for sharing, Mac! We're so glad the blue oysters are working out.
