'Harbor Blue' oyster (Pleurotus ostreatus) is a very productive commercial strain of blue oyster from Pennsylvania that fruits dense clusters with dark grayish-blue caps. It produces best in cooler temperatures but also performs well during the warmer months. Averages 1-2 lbs first flush off of 5 lb supplemented sawdust blocks but will also produce off sterilized straw substrate.
Our liquid culture syringes are ~10ml and come sealed in a plastic sleeve with a sterile 16 gauge needle and alcohol wipe.
About liquid culture:
Liquid culture is mycelium suspended in a nutrient-rich medium. Syringes are beginner-friendly and ideal for those looking for an easy way to inoculate grain bags and jars.
Directions for use:
For best results, refrigerate upon receipt. Syringes should be inserted into a self-healing injection port. Always handle using sterile technique and shake thoroughly before use. We recommended inoculation in either a still air box or flow hood to reduce the possibility of contamination. If you plan to re-use your needle, sterilize before and after each subsequent use.

Everything came in a timely manner. It was easy to inoculate and I got 3 beautiful flushes. They were absolutely delicious and I am definitely getting more.

Super Easy
This was an experiment with wood chips and sawdust from a tree that fell in my front yard. Could not have been happier with the results. The mushrooms fruited extremely quickly, gave me multiple flushes and were absolutely delicious.

Oyster Time
Decided to dive right in after getting a mushroom growing kit in box. Decided to purchase bin and bundle, and use blue oyster since it taste so good. Website was user friendly, best deal i could find out, great point system and quick customer feedback with questions. Will definitely be ordering more, even more inspired to after watching YouTube videos they post.

Worked great
Just what we needed for a mycoremediation experiment!

Worth it!
This is one of the most tenacious myceliums to colonize, but this strain is crazy. Whether its on pasteurized or sterilized substrate, this mycelium takes off and has you eating delicious fruits in not time!

Worked Great
Using the item was less than 4 stars for sure. Need more detailed instructions on cap removal, make it for dummies. Other than that, product worked great as it should. Hope with all the fumbling off the multiple caps I didn't contaminate anything but will see!

Newbie, most likely a lifer!
Going great so far! This is a new hobby for me, and I’m having a blast, along with learning so much. Thanks for such a great positive experience
