    Blue Oyster Ready to Grow Bag — Just Open and Mist

    Skip inoculation, skip colonization wait, skip the flow hood. This bag is already inoculated and colonized with vigorous Blue Oyster (Pleurotus ostreatus var. columbinus) mycelium — all you do is open it, mist daily, and watch mushrooms grow. Perfect for first-time growers, curious kids, or anyone who wants fresh mushrooms without the lab work.

    Specifications

    • Species: Blue Oyster (Pleurotus ostreatus var. columbinus)
    • Status: Fully colonized and ready to fruit
    • Contents: Grain + substrate in one bag
    • Time to first harvest: 7-14 days after opening

    How to Use

    • Cut an X in the bag plastic to expose the colonized block.
    • Mist the exposed area 2-3 times daily with clean water.
    • Keep in a humid spot with indirect light and fresh air exchange.
    • Watch for pin formation, then harvest when caps begin to flatten.

    Storage

    Keep sealed until ready to fruit. Store at room temperature (65-75°F) and use within 14 days of receipt for best results. Do not refrigerate.

    Quality & COA

    Each bag is inoculated under sterile conditions and colonized in our clean facility. Batches are test-grown to confirm viability before release.

    How to Use This Ready-to-Fruit Block

    1. Unfold or open the bag — your block is already fully colonized and ready to fruit.
    2. Mist daily with clean water to maintain humidity.
    3. Provide fresh air exchange by fanning the bag or leaving it slightly open.
    4. Maintain 80-90% humidity and temperatures appropriate for the species (typically 65-75°F).
    5. Harvest when caps open — pick mushrooms before the veil breaks for best quality.

    Tip: These blocks are ready to go — no incubation or colonization needed. Just provide humidity and fresh air.

    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.
