Why Rye?

Rye is the preferred grain spawn among experienced growers. Its small kernels give many inoculation points, faster colonization, and easy break-and-shake. It's ideal for making grain spawn to expand into bulk substrate.

Ready To Inoculate

Each jar is prepared and autoclave-sterilized under controlled conditions, then sealed and shipped ready to use. Wipe the injection port with isopropyl alcohol, flame-sterilize your needle, and inject 1–3 ml of liquid culture or spore solution.

Reusable & Autoclave Safe

Both the Bormioli jar and the lid withstand autoclave and pressure-cooker cycles. Once your harvest is done, clean the jar, refill it with fresh grain, and sterilize it again. It's a durable, eco-friendly alternative to single-use spawn bags.

Suitable For

Oyster, Lion's Mane, Shiitake, Reishi, King Oyster, Pioppino, Enoki, and other gourmet and medicinal mushroom species.

How To Use

Sanitize the injection port with 70% isopropyl alcohol. Inject your liquid culture or spore syringe. Incubate at 21–26°C, away from direct light. Shake the jar at about 30% colonization to speed up growth. Once fully colonized, spawn to bulk substrate or use for grain-to-grain transfer.

Storage

Store in a cool, dark place and inoculate as soon as possible after receipt for best results.

Shipping

Carefully packed to protect the glass. Ships from Italy.
