Description
Black Pearl King Oyster Liquid Culture Syringe (10cc) — a Pleurotus hybrid developed in Western Europe, with first-generation (G1) isolated genetics from Myco Labs. Black Pearl King produces large, dark-capped fruit bodies with a deeper umami flavor than any standard oyster, and it colonizes fast enough to stay beginner-friendly despite the premium result.

Why Growers Choose Black Pearl King
Black Pearl King is the flavor pick of the oyster group. Chefs single it out for a savory depth that ordinary Pearl and Blue Oysters do not reach, and the dark caps make an obvious visual difference on a plate or a market table. It is a hybrid, developed in Western Europe specifically to combine that flavor with commercial reliability.
What keeps it accessible is how little it asks for. It runs on almost anything cellulose-based — straw, sawdust, wood chips, newspaper, plain cardboard — and colonizes vigorously across all of them. You can put it on a premium hardwood substrate for maximum yield or on recycled waste material for near-zero cost, and it will produce either way.
It fruits cool at 60–70°F, placing it with Blue, Pearl and King Blue as an autumn and winter strain rather than a summer one.
What's In the Package
- One 10cc liquid culture syringe, sealed and lab-tested

How to Use Your Liquid Culture Syringe
- Let the syringe come to room temperature, then shake gently to redistribute the mycelium evenly through the broth.
- Flame-sterilize the needle until it glows orange and let it cool for a few seconds.
- Wipe the injection port on your grain spawn bag or jar with the alcohol prep pad.
- Inject 2–3cc per quart jar, or 3–5cc per 3–5 lb spawn bag. One 10cc syringe inoculates roughly 2–4 containers.
- Incubate at 70–75°F in the dark until the grain is fully colonized, shaking once at roughly 30% colonization.
- Spawn to bulk substrate at roughly 1:3 grain-to-substrate, then drop temperature and introduce fresh air to trigger pinning.
Frequently Asked Questions
What is a Black Pearl King Oyster?
It is a Pleurotus hybrid developed in Western Europe, bred to combine large, dark-capped fruit bodies with a richer savory flavor than standard oyster varieties. It grows using ordinary oyster technique, so no special method is required — the difference shows up on the plate rather than in the process.
What substrate should I use for Black Pearl King?
Almost anything cellulose-based. It performs on straw, hardwood sawdust, wood chips, newspaper and cardboard, which is unusually flexible even by oyster standards. Supplemented hardwood sawdust gives the largest and densest fruits; cardboard and newspaper work well for low-cost or recycling-focused grows.
What temperature does Black Pearl King need?
Incubate at 70–75°F and fruit at 60–70°F. That puts it in the cool-weather group alongside Blue, Pearl and King Blue Oyster, making it a good autumn and winter strain. For summer growing in an unconditioned space, Pink or Golden Oyster is the better fit.
How does it compare to regular Pearl Oyster?
Black Pearl King gives darker caps, larger fruit bodies and a deeper, more umami-forward flavor. Pearl Oyster is more tender and milder. Growing conditions are effectively the same for both, so the choice comes down to whether you want delicate texture or bold flavor.
How much liquid culture do I use per bag or jar?
Use 2–3cc per quart grain jar and 3–5cc per 3–5 lb spawn bag. A single 10cc Black Pearl King syringe will inoculate roughly two to four containers. Adding more than the recommended dose does not speed colonization meaningfully and simply uses up the syringe faster.
Do I need a flow hood or still air box to use liquid culture?
A still air box is strongly recommended and a laminar flow hood is better still. Liquid culture syringes ship sealed and lab-tested, but the moment you pierce an injection port you are exposing your grain to whatever is in the room air. Working in still air with flame-sterilized tools dramatically improves your success rate.
How should I store the syringe before use?
Keep it refrigerated between 35 and 45°F and never freeze it — freezing ruptures the cell walls and kills the culture. Store it in the sealed bag it shipped in, away from strong odors. Bring it back to room temperature and shake gently before injecting.
Packed to Arrive Alive
A liquid culture syringe is living mycelium, and the trip from our Illinois lab to your door is the part of its life you have the least control over. That is why every Myco Labs liquid culture ships inside a foil-lined insulated mailer rather than a plain envelope. The insulation buffers the syringe against summer heat sitting in a delivery truck and against sub-freezing temperatures in winter, so your culture arrives viable in either extreme.
When it arrives: move the syringe to the refrigerator at 35–45°F until you are ready to inoculate. Never freeze it. Bring it back to room temperature and shake gently before use.
Let customers speak for us
Working good. Lights my closet just enough for the environment I need! Thanks!
It's started good. Let's hope it continues to grow so I can break a shake it!
Bought the 3-Pack Premium Quick-Colonizing 5-grain Jar (32oz) and inoculated 9 days ago. Love it! Colonization quick and clean. Highly recommend!
So when i got this i was worried because of past experiences. Leave it up to midwest to be nice a patient with me. The team at bonsai gives great support . This flow hood is meant to run a little higher than normal clean room standards because most people need this working from home . This thing is nice and laminar. Very inform . With a speed contoller i average about .45 m/s across the face. It passed everyone one of my agar grid tests . Which blows my mind becuase i ran it through three diffrent 30 mins agar grid tests . Ive used a few flow hoods and this one is my favorite . Perfect for any home or small buisness.
"Upgraded to the MycoClimate 44Q and the difference in consistency is night and day. The dual-chamber water-bath heating keeps temperatures rock-solid without drying out the substrate like standard heating mats do, and the automated HEPA air pump takes all the stress out of fresh air exchange—even tucked away inside a closet.
i saw germination in my jar within 2-4 days!! I ordered a 3 pack and i injected 3 different strains and they are all colonizing and germinating very rapidly i see ne difference in rate of germination for genetics they are all moving about the same speed im happy with my purchase!
100% RELIABLE EVERY TIME I LOVE YOU MIDWEST THANL YOU TEAM
Reliable and I know what I am getting. Pretty quick colonization.
I got the grow bag instead of jars this time because I am not interested in the steps of the jars.
Been there done that.
I am not an expert🤓 but now I have enough knowledge and experience to call myself an apprentice.
The thrill of the process is gone. Just give me the dam mushrooms.
I am hurry up and waiting😉.
Seems to be working is all I have to say at this point day 7. The green is reflection not mold.
All I knew was I wanted to grow some mushies for me and the boys, I did a bunch of research on companies and you guys have been around the longest and have the best reviews for these types and I was not disappointed. Took exactly 8 weeks to harvest my first 4 ounces and more on the way! Thanks so much for all the awesome guides and videos! Made it so easy!
It's a great monotub kit. I recommend throwing the horse booster, used the whole bag to 4 small quick grain jars and the 7.5 mix. I learned how to do a pf tek with these guys 10 years ago when you still got the sticky light for the lid and the monotub was a blue tub with polyfill. These monotub kits have come a very long way since then. Substrate has always been clean and performed better than what I try to recreate with a pressure cooker.
10cc liquid culture and follow the instructions mgk gives you hard to mess up.
So far , I only have a little bit on agar , and am only beginning to study this mycelium. Super excited to try to put it to use in this Aspen tree.
Everything is looking real good so far
If your ever in need of replacing your hepa filter on your bonsai flowhood these are an exact match to whichever size you have. Worth noting that a filter will actually work a lot longer than is recommended due to physics but if your externals get dirty or damaged it’s worth replacing.
