King Oyster Ready To Fruit Block

King Oyster Mycelium: Thick Stems, Gourmet Aroma, Superior Texture


Why Grow King Oyster?

  • Chef’s Favourite: Dense “scallop-like” stems and premium presentation.
  • Strong Colonization: Mycelium forms tight, powerful networks across hardwood substrates.
  • Fresh Herbal Aroma: Mild, slightly earthy fragrance when harvested.
  • Rich Savoury Flavour: Deep meat-like umami that intensifies when roasted or grilled.
  • Long Storage Life: Holds firmness longer than most mushrooms.

Recommended Formats

  • Syringes: Clean and simple to inoculate bags or LC.
  • Rye Spawn: Great for building heavy fruiting blocks.
  • Hardwood Blocks: Best substrate for large, meaty stems.

Popped a colonized rye block into bulk Friday night, pinning started in a week and a half. Roman gave me a same-day mix ratio for coir that’s working stupidly well. Highly recommend for exotic mushrooms grow.

I’m terrible at grain, so these ready-to-go blocks are a lifesaver!!!

Ordered a Lion’s Mane ready-to-fruit block. Literally got home, cut an X on the side, put it on my kitchen counter. 11 days later — massive snowball. Harvested 600 g fresh with scissors. Roman said “don’t overthink it” and he was 100 % right.

Pink Oyster block arrived last Thursday. Cut the X Friday morning, in a week woke up to neon pink clusters everywhere. 400 g first pick and it’s already pushing a second flush. Easiest thing I’ve ever grown.

King Oyster block is ridiculous. Cut the X, stuck it in my spare shower for humidity. 12 days later harvesting thick 300–400 g trunks. Tastes better than Superstore

Ordered 15 ready to fruit blocks for a big winter grow. All arrived snow-white. Roman even threw in a free liquid culture and a couple mini grow kits, because I mentioned it was my first bulk run. Northern Ontario approved!

Me and my husband got 10-bag bundle from them, every single one colonized perfectly. They answered like 12 questions I’m-paranoid questions over a week. Definitely worth the price just for the support!
