Straw for Mushrooms

Out-Grow's premium wheat straw is a horticultural-grade substrate trusted by cultivators at every level. With naturally high cellulose content, wheat straw provides an ideal food source for a wide range of gourmet mushroom species including oyster, shiitake, and lion's mane, while its structure promotes excellent moisture retention for consistent colonization and reliable fruiting.

Each order ships as a full cubic foot — a 12x12x12 box packed tight with long-cut wheat straw, weighing approximately 4lbs. That's enough substrate for multiple simultaneous projects.

To prepare, pasteurize in water held between 160-180°F for 1-2 hours, inoculate with your chosen spawn, and allow to colonize in a clean environment.
