Our Blue Oyster is a first-generation Pleurotus ostreatus isolate kept in the Myco Labs lab for one reason: it runs hard. It colonizes grain fast enough to outpace most low-level contamination, fruits in dense clusters of blue-gray caps that fade toward pewter, and handles more substrates than almost any gourmet species we culture.
An aggressive grain run leaves less room for mold and bacteria, which makes it forgiving while you dial in sterile technique.
Straw, sawdust and Master's Mix, plus cardboard and shredded paper that most gourmet species reject.
It fruits best at 60–70°F, so it's the oyster to run through fall and winter when your space cools off.
Let the syringe reach room temperature, then shake it gently to break up and spread the mycelium through the broth.
Flame the needle until it glows, let it cool a few seconds, and wipe the injection port with the included alcohol pad.
Use 2–3cc per quart jar or 3–5cc per 3–5 lb grain bag. One 10cc syringe inoculates about 2–4 containers.
Keep it at 70–75°F in the dark. Shake once at about 30% colonization to speed things up.
Cool it down to pin: after spawning to bulk, drop the temperature into the 60s and open up fresh air. Blue Oyster pins hard on that combination.
From our lab to your grainRun it into jars with wide-mouth cultivation lids or your own lids with self-healing injection ports. Spare 16G needles and sterile Luer Lock syringes are sold separately.
Use 2–3cc per quart grain jar and 3–5cc per 3–5 lb spawn bag. One 10cc Blue Oyster syringe inoculates roughly two to four containers. Using more doesn't speed colonization much; it just uses up the syringe.
Expect 10–14 days at 70–75°F. Shaking the jar or bag at about 30% colonization often brings it down to 8–10 days.
Pasteurized straw gives the most yield for the money; supplemented hardwood sawdust or Master's Mix gives denser, meatier clusters. Blue Oyster also fruits on plain cardboard and shredded newspaper.
Match the strain to your room. Blue Oyster fruits cool at 60–70°F, so it's the fall and winter choice. Pink (72–85°F) and Golden (71–78°F) are warm-weather strains for summer or an unheated garage.
Refrigerate it at 35–45°F in the bag it shipped in and never freeze it; freezing ruptures the cells and kills the culture. Bring it to room temperature and shake gently before you inject.
Liquid culture is living mycelium from an isolated culture, so it skips germination, colonizes days faster and gives genetically consistent fruits. Spores have to germinate and pair up first, which is slower and more variable from grow to grow.
Liquid culture is living mycelium, so every syringe leaves our lab in a foil-lined insulated mailer. The insulation buffers it against summer heat in a delivery truck and against sub-freezing winter temperatures, so it arrives viable either way.
When it arrives: refrigerate the syringe at 35–45°F until you're ready to inoculate. Never freeze it. Bring it to room temperature and shake gently before use.
Great product!
I have had 4 flushes from some blocks recently using pasteurized straw only (5 lb blocks). It's cold ( 55-65 Deg F ) in my tent, being that I get fresh Winter air from a vent pipe going into the garage which has very low CO2 and blue oysters like it a bit on the cold side. My opinion has been that this strain are very strong growers. Very satisfied!
This is my second culture order. They are packaged well and shipped very promptly. Will order more.
Really happy with how this performs! Great growth on day 2! 5 stars!
