Get Hearty Mushrooms in No Time

Our Black King Fruiting Block features a strain that produces some of the heartiest mushrooms available for indoor cultivation. This hybrid strain grows mushrooms that are succulent and savory like blue oysters, but with the dense texture of a king trumpet. 

Black Kings are less finicky than king trumpets and grow very well indoors. When cultivated successfully, you can expect a large harvest of meaty and delicious mushrooms. However, they prefer cooler temperatures and are prone to drying out or stopping their growth if humidity is not maintained when the mushrooms are still in their early stages.

Planting Directions

<h2>How to Grow Organic Black King Mushrooms (Fruiting Block Kit)</h2> <p>Follow these steps to maximize your yield and minimize contamination risk when using your Black King Mushroom grow kit.</p> <h2>Set Up Your Fruiting Chamber</h2> <ul> <li>Use a monotub or martha tent with controlled humidity (85–95%), fresh air exchange, and indirect lighting (12-hour light/dark cycle).</li> <li>Maintain temperatures between 60–70°F (16–21°C) for best results.</li> </ul> <h2>Prepare the Fruiting Block</h2> <ul> <li>Unfold the top of the bag to create some air space above the block.</li> <li>Ensure the filter patch is exposed and unobstructed to allow proper gas exchange.</li> </ul> <h2>Initiate Fruiting</h2> <ul> <li>Make a 2–3" cut below the top seam of the bag (just enough to encourage pinning).</li> <li>Place the upright bag into your fruiting chamber.</li> <li>If pinning (baby mushrooms) does not start within 7–10 days, move the bag to your refrigerator for 8 hours, then return it to the fruiting chamber.</li> </ul> <h2>After Pinning</h2> <ul> <li>Once pins appear, cut off the top of the bag, leaving 4" of sidewalls around the block to maintain humidity.</li> <li>Return the block to the fruiting chamber and monitor daily.</li> <li>Mist the walls of the chamber to keep humidity high but avoid direct misting on the mushrooms.</li> </ul> <h2>Harvesting</h2> <ul> <li>Harvest mushrooms when caps are large and convex, just before flattening.</li> <li>Twist gently or cut at the base with a clean knife.</li> </ul> <p>Clean the chamber after harvest. A second flush may occur—just keep humidity up and wait for new pins.</p>

FAQs

<h2>FAQs for Organic Black King Mushroom Grow Kit Fruiting Block</h2> <ul> <li> <strong>1. What makes the Black King mushroom unique?</strong><br> This hybrid variety combines the savory flavor of blue oysters with the dense, meaty texture of king trumpets. It's heartier than most oyster strains and easier to grow indoors than traditional king trumpets. </li> <li> <strong>2. Can I grow Black Kings indoors?</strong><br> Yes, this kit is made for indoor growing. Black Kings thrive in a home setup as long as you can maintain cool temps and high humidity—think grow tents, greenhouses, or a Martha setup. </li> <li> <strong>3. What conditions do Black Kings need to fruit properly?</strong><br> They prefer cooler temperatures (ideally around 55–65°F) and consistent high humidity. If conditions are too dry, especially during early growth, the mushrooms may stop developing or dry out prematurely. </li> <li> <strong>4. How long does it take to see mushrooms after starting the kit?</strong><br> Typically, you’ll see pins (baby mushrooms) within 7–10 days after starting fruiting conditions. Full-size mushrooms are usually ready to harvest in 14–21 days. </li> <li> <strong>5. How should I harvest and store Black King mushrooms?</strong><br> Harvest when caps are fully formed but before they flatten out. Twist or cut them at the base. Store in the fridge in a paper bag for up to a week—they stay fresher longer than most oyster mushrooms due to their dense texture. </li> </ul>
