Organic Blue Oyster ‘Spray & Grow’ Mushroom Growing Kit

Blue Oyster Mushroom (Pleurotus ostreatus var. columbinus)
Known for their striking bluish-gray caps, blue oysters are hearty mushrooms with a rich, earthy taste. They are one of the most versatile oyster varieties, perfect for grilling, roasting, or adding depth to soups.

North Spore's beginner-friendly, USDA-certified organic oyster mushroom countertop kits make growing your own mushrooms so easy. Just open the front of the box, cut an “X” into the plastic bag, spray with water 2-3 times a day, and watch them grow!

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 over at North Spore (going all the way back to when the began as an urban farm.) After perfecting their 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!)

About the kit:

These 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!)

That's not mold, it's mycelium!

Your kit includes an amended sawdust block fully colonized with mushroom mycelium. It may appear covered with a soft, white, mold-like substance - that's the mushroom mycelium! It is completely normal. The mycelium of some species is more prominent than others.
