'Harbor Blue' PO1 (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 with a sterile 16 gauge needle and alcohol wipe.

About liquid culture syringes:

Liquid culture syringes are mycelium colonized in a nutrient-rich broth. They are beginner-friendly and ideal for those looking for an easy way to inoculate grain bags and jars. Handle using sterile technique to prevent contamination.

Long awaited success

It’s very satisfying to eat the mushrooms you grew. These just keep producing more mushrooms. I was afraid I waited too long after the substrate was completely colonized but I mixed them up with straw and wood chips anyways. I bought some little baskets so they could come out through the holes and I had some leftover. I placed the remaining amount in a deep aluminum tray with drainage holes and they’re growing better than the ones in the basket. They look a little brown but it might be because they get a little sun.

Thanks for sharing the photos, Jen! Looking great! Please reach out if you ever need anything.

Fast, contamination free inoculation

In a little over two weeks a CC or two fully inoculated a mason jar of sterilized grain, and I did this with 6 jars. Looking forward to spawning to bulk and getting these fruiting soon!

Thanks for the great review, Ross! We really appreciate your support.

This is my first time growing mushrooms and I have to say all the time everyone on u tube says it takes to grow mycelium in petri dish and uncle Ben's rice is slow compared to this blue oyster culture its amazing how fast it grows on on dish and bottom of Ben's rice bag is fully colonized will definitely buy this one again after I try the other three I just ordered pink and yellow oyster and lion's main can't wait to see them grow thanks for the wonderful culture syringe

We're so glad everything is working out for you! Thanks for the great review.

Product is good. I found a competator that offers the same product for 30% less though.

Agressive

This is an aggressive strain! 4 days in the grain bag and I see massive colonization.

Thanks so much, Andrea! The Blue Oysters are always show-stoppers—happy to hear you enjoyed them

Mycelium taking off

Inoculated a homemade oat and vermiculite spawn with one of my two blue syringes and the mycelium seems happy. Can’t wait for it to fully come to fruition!

Sounds great, Faith! Let us know how your grow goes. We appreciate the review!

Excellent genetics

Tested out culture on agar plates first to make sure everything was clean. Then I multiplied the culture in a sterile nutrient rich solution and injected many bags.

Thanks so much for the continued support, John! We so appreciate it!

Blue Oyster LC for Outdoor Bed

Syringe was contamination-free and mycelium incredibly hearty and fast growing. I already have mushrooms in my outdoor bed only a month after putting the spawn in a straw and oak chip mix

Wow, Dana! Thanks for sharing. Best of luck with your grow!

I’m kinda new growing mushrooms. For some reason I thought I could just re-inject my original spawn kit! Upon further investigation I learned I needed a new substrate to inject the spores. I did that and almost a year later I’m seeing success with a new batch.

Thanks for sharing, Jen! If you need help with anything, please reach out.

Eh don’t really care for it. Shipping took almost 2 weeks and the cultures aren’t very aggressive.
