'MushBucket' Blue Oyster Mushroom Bucket Grow Kit

At North Spore, our journey began with blue oyster mushrooms in buckets. In fact, bucket-grown oysters were our first major harvests—and for years, they were our primary source of income. This kit is a tribute to those roots: simple, effective, and designed for results.

Whether you're a first-time cultivator or a seasoned mushroom enthusiast, this beginner-friendly bucket kit makes it easy to grow mushrooms in almost any environment. Designed for simplicity and performance, the pre-drilled food-grade bucket is ready to use right out of the box—no special tools or experience required!

The complete kit includes a 3 lb bag of fully colonized organic Blue Oyster grain spawn (Pleurotus ostreatus), a fast-growing, cold-tolerant strain known for its bluish-gray caps, savory umami flavor, and meaty texture. As our most productive oyster strain, Blue Oyster is ideal for beginners and trusted by commercial growers alike for its consistent, high-yield performance.

This system provides everything you need to cultivate mushrooms at home (just bring your own stock pot for pasteurization). The included chopped straw is shredded to the ideal size for colonization, while the premium North Spore grain spawn delivers fast and reliable growth. From inoculation to pinning, you could see results in as little as 7 days!

What to Expect with Your Blue Oyster Spaw

Our USDA-certified organic Blue Oyster grain spawn is one of our top performers. This aggressive colonizer thrives on straw or sawdust indoors and can also be grown outdoors using straw beds or wood chips. Outdoors, Blue Oysters typically fruit prolifically in cooler weather—making them great candidates for early spring or late fall harvests.

To get the best results, remove your grain spawn from the shipping box immediately. Unfold the top of the bag to create air space, and ensure the filter patch remains unobstructed—this helps your mycelium breathe and stay healthy.
