Why We Love Them:
Blue oyster mushrooms are velvety, savory, and mild and pair perfectly with just about any recipe! Blue oysters are a staple here at North Spore (going all the way back to when we began as an urban farm.) After perfecting our blue oyster kits over the years, they’ve become one of the easiest kits to get multiple fruitings from and should produce a second flush of mushrooms (or more!)
100% Guaranteed
Our blue oyster mushroom kits are reliable producers and tend to yield large flushes of beautiful light grayish-brown to deep blue-gray mushrooms when given adequate humidity. With continued proper care, you should be able to get multiple flushes. We 100% guarantee your first flush of mushrooms, but hope you'll try for 2 or 3!
It's Mycelium!
Your kit includes an amended sawdust block fully colonized with mushroom mycelium. It may appear covered with a soft, white substance - that's the mushroom mycelium! It is completely normal and means your kit is packed with fungi ready to fruit. The mycelium of some species is more prominent than others.

FAQs
<h2>FAQs for Organic Blue Oyster ‘Spray & Grow’ Mushroom Growing Kit</h2> <ul> <li><strong>1. How long does it take for mushrooms to grow?</strong><br> With the right conditions, you’ll see your first harvest in as little as 7 days after activating the kit. The full flush may take 10–14 days. Patience pays off—just keep misting and watch the mushrooms do their thing.</li> <li><strong>2. How many times can I harvest mushrooms from one kit?</strong><br> Most users get at least 2 flushes (harvests), sometimes even a third. After your first harvest, soak the block overnight and keep misting daily to encourage more growth.</li> <li><strong>3. Where should I keep my mushroom kit for best results?</strong><br> Place it in a spot with indirect light and good airflow—like a kitchen counter or near a north-facing window. Blue oysters love humidity, so a bathroom with natural light can also work well.</li> <li><strong>4. Is the white fuzzy stuff in the box mold?</strong><br> Nope, that’s the mushroom mycelium—it’s the living body of the fungus and exactly what you want to see. It may look like soft white fluff, but it’s a sign your kit is healthy and ready to fruit.</li> <li><strong>5. Do I need to do anything special to get the mushrooms to grow?</strong><br> Just follow the simple 1-2-3 steps: open the box, mist daily with the included spray bottle, and keep the kit in a humid area. If your space is dry, try placing a humidity tent (like a loose plastic bag with holes) over the opening to help the mushrooms thrive.</li> </ul>
