Get Beautiful Blue-Gray Mushrooms
Our Blue Oyster Fruiting Blocks feature a strain that produces beautiful clusters of mushrooms with bluish-gray to brownish-gray caps, depending on lighting conditions. They have a rich umami flavor and a soft meaty texture that lends itself to most recipes.
Blue Oyster Mushrooms are great for beginners as they are reliable producers and tend to grow large flushes. They are also one of the easiest blocks to get subsequent fruitings and, if kept in the right conditions, should reliably produce a second flush or more!

Planting Directions
<h2>How to Grow Organic Blue Oyster Mushrooms from a Fruiting Block</h2> <ul> <li><strong>Step 1: Prepare Your Setup</strong> <p>Place the fruiting block in a controlled environment like a <em>monotub</em> or <em>martha tent</em>. These chambers help maintain proper humidity, temperature, and airflow to reduce contamination risks and support mushroom development.</p> </li> <li><strong>Step 2: Prep the Fruiting Block</strong> <p>Open the top of the bag to create air space above the block. Make sure the filter patch is clear of obstructions to allow for proper gas exchange.</p> </li> <li><strong>Step 3: Initiate Fruiting</strong> <p>Use a clean knife or scissors to cut a 2–3” slit under the top seam of the bag. Stand the block upright inside the fruiting chamber. This cut encourages fresh air exchange and triggers pinning (baby mushroom growth).</p> </li> <li><strong>Step 4: Cold Shock (Optional)</strong> <p>If pinning hasn’t occurred after several days, place the entire block (still in the bag) in the refrigerator for 8 hours. This can stimulate fruiting. Return it to the fruiting chamber afterward.</p> </li> <li><strong>Step 5: Support Fruit Growth</strong> <p>Once pins appear, cut the top off the bag, leaving 4” of the plastic as sidewalls to retain moisture. Keep the block in the chamber with 85–95% humidity, indirect light (12 hours/day), and good airflow.</p> </li> <li><strong>Step 6: Harvest</strong> <p>Harvest when caps are just starting to flatten but before edges curl up. Twist gently or cut at the base. Mist as needed to maintain humidity.</p> </li> </ul> <p>After harvest, you may get 1–2 more flushes. Let the block rest 1–2 weeks, then repeat the fruiting process.</p>
