What You Get

• One 3cc syringe containing live king blue oyster mycelium in sterile honey-water medium
• Lab-isolated hybrid genetics — clean, vigorous, and ready to grow
• Sealed for immediate inoculation or refrigerated storage

How to Use

This mushroom culture syringe is straightforward to work with:

• Inoculate grain spawn — inject into sterilized grain jars or bags to create your own king blue oyster spawn
• Transfer to agar — drop onto pre-made agar plates for isolation work, sector selection, or archiving your culture
• Expand into liquid culture — add to sterile nutrient broth to multiply your culture before large-scale inoculation

Best results come from working in a still air box or laminar flow hood. Sterilize injection ports and work surfaces with isopropyl alcohol.

Species Profile

King blue oyster is a hybrid within the Pleurotus ostreatus complex, selected for its balance of fast colonization, cold tolerance, and meatier stem structure compared to standard blue oysters. It produces attractive blue-grey caps on sturdy white stems and performs well on supplemented hardwood sawdust or straw. This is an excellent choice for growers who want a versatile, high-yielding oyster variety.

Storage & Shelf Life

Store in the refrigerator at 2-8°C. The culture stays viable for several months, but inoculating within 60 days will give you the fastest colonization times. Let the syringe warm to room temperature before use.
