1lb Grain Spawn

Our 1lb Grain Spawn Bag, crafted with premium popcorn and 3.5% erythritol, is designed for serious cultivators looking to maximize mycelial speed, density, and biological efficiency.

Why Popcorn?
Popcorn offers a perfect combination of durability, hydration, and nutrient retention, making it an excellent substrate for a wide range of gourmet and functional mushroom species.

Why Erythritol?
This natural sugar alcohol acts as a mycelial stimulant, promoting faster colonization and thicker rhizomorphic growth without compromising sterility or shelf life.
