Our flagship grow kit. Blue oyster mushrooms are an incredible mushroom to grow, cook, and eat. They’re beautiful, versatile, delicious, and nutritious. This is the place to start for new mushroom growers or anyone who wants an impressive yield of full, meaty mushrooms.
Blue oyster mushrooms grow so quickly that you can practically see them grow. After they first develop mushroom pins, they've been known to double in size every day until harvest. Depending on how much light they're exposed to, their caps will range from brown to gray to slate blue, and they grow in thick full clusters.
Myqo mushroom grow kits are the easiest, most sustainable grow kits you can get. Each kit is mixed and packed by hand using recycled coffee grounds that we collect from local cafes and agricultural byproducts like straw and soybean hulls. We use low-energy and low-water techniques, use minimal recyclable packaging, and provide free, carbon-neutral shipping.
Each kit includes an inoculated blue oyster mushroom block, instructions, recipe card, and spray bottle.
Growing Instructions
Get It Started
Place your kit in an area with good air flow and ambient light. Peel off the round sticker on the front of the kit. This is where your mushrooms will grow.
Spritz It
Generously spray the “X” several times a day with water using the spray bottle. After about 4–6 days, you will start seeing mushroom “pins” develop.
Watch Them Grow
Continue to spray the mushrooms. At this point, your mushrooms will grow fast (they might even double in size every day!)
Harvest Time
About 5 days after the pins form, your mushrooms will be ready to harvest. Cut the cluster off at the base right before the caps completely unfurl and flatten out.For more tips, read our detailed instructions or visit our FAQ.
