King Blue Oyster Commercial Liquid Culture (200ml)

King Blue Oyster Commercial Liquid Culture (200ml)

Produce king blue oyster mushrooms at commercial volume with this 200ml liquid culture jar. This Pleurotus ostreatus hybrid delivers the cold tolerance and colonization speed of blue oysters with improved stem thickness and shelf life — traits that matter when you are selling at market or supplying restaurants. Lab-isolated genetics, produced in Canada at our CFIA-licensed facility in Brantford, Ontario.

What's Included

• One 200ml mason jar with live king blue oyster mycelium in sterile honey-water medium
• Self-healing injection port for sterile, repeated culture draws
• Synthetic filter cap for gas exchange during storage and transport
• Lab-isolated hybrid genetics — selected for commercial performance

How to Use

Use a sterile syringe to draw culture through the self-healing injection port. A single 200ml jar provides enough culture to inoculate a full production batch of grain jars or grow bags.

• Sterilize the injection port with isopropyl alcohol before each draw
• Use a sterile 18-gauge needle and syringe
• Inject 2-5ml into each grain jar or spawn bag
• Gently swirl the jar before drawing to suspend mycelium

Species Profile

King blue oyster is a hybrid within the Pleurotus ostreatus complex, selected for meatier stems and improved post-harvest durability compared to standard blue oysters. It retains the cold tolerance and fast colonization of its parent lines while producing a more substantial fruiting body that holds up during transport and display. An excellent dual-purpose variety for farms that sell both fresh and value-added products.

Why Commercial Size

Running a commercial grow operation means every batch needs to perform. The 200ml format lets you inoculate an entire production run from one genetically uniform source. The self-healing injection port supports many draws without compromising sterility, and the sealed jar format is easy to store until your next production cycle.
