    Inoculated Slant Tube — Blue Oyster

    A pre-inoculated MEA slant tube containing a vigorous, clean culture of Blue Oyster (Pleurotus ostreatus var. columbinus) mycelium. Ready for transfers to grain, liquid culture, or agar plates. Slant tubes are ideal for long-term storage and maintaining genetic integrity of your favorite strains — compact, sealed, and built to last.

    What It's For

    • Long-term storage: Keep your Blue Oyster culture viable for months under refrigeration.
    • Culture expansion: Transfer to grain or LC when you're ready to run a grow.
    • Genetic backup: Maintain a clean master culture so you always have a reliable starting point.

    Who Needs It

    Serious cultivators who want to bank a specific strain, anyone doing agar work, and growers who want to maintain their own culture library instead of re-buying syringes every cycle.

    Specifications

    • Species: Blue Oyster (Pleurotus ostreatus var. columbinus)
    • Media: MEA (Malt Extract Agar) slant
    • Format: Single slant tube
    • Status: Culture actively growing on arrival

    How to Use

    • Work in front of a flow hood or inside a still-air box.
    • Use a sterilized tool to take a wedge transfer from the slant.
    • Transfer to grain, LC, or fresh agar plates.
    • Re-cap and refrigerate slant for long-term storage.

    Storage

    Store capped and refrigerated at 35-45°F for long-term culture storage. Culture can remain viable for 6-12 months under refrigeration. Let warm to room temperature before opening to prevent condensation. Inspect for contamination before use.

    Quality & COA

    Each slant is inoculated under sterile conditions and visually inspected for clean, vigorous growth before release. Representative slants are test-transferred to confirm viability.

    How to Use This Agar / Slant Culture

    1. Work in a sterile environment — use a still air box or laminar flow hood. Sanitize all surfaces and tools.
    2. Transfer a wedge of colonized agar to a new agar plate or grain bag using a sterile scalpel or loop.
    3. Seal the plate with parafilm or tape to prevent contamination.
    4. Incubate at 70-75°F and watch for mycelial growth spreading across the new medium.

    Uses: Agar plates and slants are ideal for strain isolation, expansion, and long-term storage. Slants are especially useful for preserving genetics in a compact, long-lasting format.

    What's in the Box

    • 5-pack of inoculated agar plates or slant tubes
    • Sealed and sterilized for safe transport

    Shipping & Storage

    All orders ship within 1-2 business days from our Colorado facility. Liquid cultures ship in insulated packaging to maintain viability. Store LC syringes in the refrigerator (35-45°F) until use. Grain spawn and substrate bags should be used within 2 weeks of delivery for best results. Ready-to-fruit blocks can be stored at room temperature for up to 2 weeks.

    Our Clean-or-Replace Guarantee

    Every liquid culture is test-inoculated on agar before release to verify purity and viability. If your culture arrives contaminated or fails to colonize, contact us within 14 days with a photo and we'll send a free replacement. No return required.

    New to Mushroom Growing?

    If this is your first grow, we recommend starting with a All-in-One Grow Bag or a Ready-to-Fruit Block — both are designed for beginners and require minimal equipment. For liquid culture use, you'll also need a grain spawn bag and a substrate bag. Check out our growing guides for step-by-step instructions.
