    Myco Labs is excited to introduce our premium 3LB Colonized Grain Spawn, a top-choice product for both professional mushroom cultivation and passionate mycologists. Our grain spawn stands out due to its exceptional quality, originating from first-generation genetics across a variety of gourmet mushroom strains. This guarantees not only vigorous growth but also abundant yields.

    Crafted from certified organic rye, milo & millet grain, our grain spawn is a thriving bed of mushroom mycelium. It's the preferred choice for inoculating sterilized or pasteurized substrates, and it's a staple in high-volume commercial production. For optimal results, we advise using our grain spawn within one to two months of purchase. Most species require refrigeration, except for the Pink Oyster strain, which should be kept at room temperature and used within two weeks.

    Please note, we do not provide instructions for making mushroom blocks as each grower's setup and mix preferences vary.

    We now carry the following varieties in stock, ready to ship!

  • Lion's Mane: Celebrated for its cognitive benefits.
  • Pink Oyster: Prized for its meaty texture.
  • Blue Oyster: Distinguished by its unique flavor.

    Thanks guys! I was in a pinch and needed some Lion's Mane grain spawn for our production run. Ordered 10 bags and they shipped within 12 hours and arrived in 2 days! I am used to waiting 2-3 weeks for grain spawn orders. They actually weigh over 3lbs each and look promising! Will update review after xfer to 10lb blocks!
