Corn Spawn Bags: Chunky, Funky, and Built for Speed


Why Our Corn Bags Just Work (The Inocblock Difference)

  • Massive Inoculation Points: Corn’s naturally large kernels provide big surface areas for mycelium to grab onto, resulting in explosive early colonization compared to smaller grains like millet.
  • Superior Moisture Capacity: Corn absorbs more water internally while staying firm on the outside, giving your culture a long-lasting hydration reservoir without bursting or turning mushy.
  • Commercial Sterility Assurance: Every corn batch is sterilized in a 150L industrial autoclave at 127°C for over five full hours. Dense, nutrient-rich grains like corn demand a deep sterilization cycle—and we provide it every time.
  • Low-Starch Surface = Fewer Wet Spots: Corn releases less surface starch than grains like wheat, reducing the chance of sticky clumps and minimizing bacterial risks during colonization.
  • Perfect for Aggressive Species: Species known for rapid, thick mycelial growth (oysters, lion’s mane, cubensis) thrive on corn thanks to its high carbohydrate density.
  • pH-Balanced Hydration: Every soak is done using pH-adjusted water to create a zone that favors clean mycelial dominance while suppressing competitor molds.
  • HEPA-Sealed in Toronto: All cooling, loading, and sealing take place in a sanitized studio using HEPA-filtered air—critical for a grain as nutritious as corn.
  • Fresh, Never Stored: We prepare corn spawn in small batches and ship quickly. Bags are never held for more than five days to ensure maximum biological vitality when they reach you.

Choose Your Volume: Options & Sizes

  • 1 lb (The Express Starter): Perfect for quick tests, expanding liquid cultures, or trying aggressive species for the first time.
  • 2.5 lb (The Standard): Ideal for medium-sized monotubs, shoebox grows, or transferring into bulk substrate with excellent colonization speed.
  • 5 lb (The Power Reserve): Built for serious G2G expansion, bulk production cycles, or creating large substrate blocks with enough spawn to dominate fast.

Romarrio

Toronto ⭐⭐⭐⭐⭐

Using theirs AIO bags for Pink Oyster and they colonize crazy fast — 12 days full. Roman helped me dial in the perfect fruiting temp for my apartment. Harvested 1.8 Lbs fresh this morning!

Mark

Richmond Hill ⭐⭐⭐⭐⭐

Best bags I’ve found in Canada for growing Lion’s Mane at home. Zero contamination on 10 bags. They gave me a simple side-fruiting trick that doubled my yield. Insane coral clusters. Very happy!

Chris

Calgary ⭐⭐⭐⭐⭐

Growing gourmet Chestnut mushrooms for the first time. Roman walked me through cold-shocking the bag — now I’ve got 1 kg of beautiful clusters. Will never buy grocery mushrooms again.

Bought the 5 -pack for gourmet oysters. Every bag 100 % clean. Mushrooms don't just look okay - they look restaurant-quality caps. Recommend!

Our family is obsessed with the home-grown oysters. Roman answered my million questions about drying and storing. Bags keep giving flush after flush!

Jose

Montreal ⭐⭐⭐⭐⭐

Golden Oyster inoculation kit turned my spare closet into a farm. Just cuting an X on the side instead of the top — doubled my yield. Thanks man!

Melissa

Kitchener ⭐⭐⭐⭐⭐

Ordered theirs Pink Oyster LC + 5 lb wood-lover kit. Roman helped me pick the fastest-fruiting strain for my apartment. 18 days from inoculation to pins — now I’ve got bright pink clusters everywhere!

Nicolas

Ottawa ⭐⭐⭐⭐⭐

Ordered two Lion’s Mane kits for my parents. They’re had mushrooms in 3 weeks. Roman answered all their “is this normal?” questions patiently. 10/10 gift.
