Dive into the world of mushroom cultivation with our three-pound mushroom grow bag filled with sterilized rye berries. Every bag, equivalent to 3 quarts in volume, showcases our commitment to quality by utilizing only certified organic rye. For an optimal growth experience, we've ensured the rye is fully hydrated, enriched with gypsum, and sterilized to perfection.

Why choose our mushroom grow bags?

• Immediate Use: They're prepared and primed, ready for inoculation right as you unbox them.

• Enhanced Safety: Featuring a self-healing injection port, the risk of external contamination during inoculation is significantly minimized.

Using our bags is simple: Just inject 4 to 6cc of your preferred gourmet mushroom culture, give it a gentle shake, and let it colonize at room temperature. Within four weeks or upon full colonization, you'll witness the magic unfold.
