Organic Grain Spawn - 1 kg

Our Whole Organic Spawn Bags contain 1kg of whole organic oats per bag, hydrated with mineral water, sealed in a 0.22 micron filter bag with a self-healing injection port and pressure-sterilized for 3 hours. Inoculate with liquid culture or spores, colonize, and spawn to bulk.

Rye berries are one of the most widely used grains for mushroom spawn: consistent kernel size, good moisture balance and plenty of nutrients. Every batch is soaked overnight, simmered, bagged and sterilized in our own autoclave, so each bag arrives ready to inoculate.

Why growers pick rye spawn

• Classic oat performance – Uniform grains with good moisture balance and nutrient density for dependable colonization.
• Clean break-up – Colonized oat grain separate cleanly and spread evenly through substrate.
• Sterile and ready – Soaked, simmered, sealed and pressure-sterilized in-house.
• Built for bulk – Mixes into coco coir, manure-based blends or Master's Mix for monotubs and grow bins.
• Filtered gas exchange – The 0.22 micron patch lets the bag breathe during colonization while keeping contaminants out.

How to use them

1. Prep. Wipe the injection port with alcohol and use a sterile needle and syringe.
2. Inoculate. Inject 5–7cc of liquid culture or spore solution through the self-healing port.
3. Incubate. Keep the bag at 22-26°C, out of direct light and undisturbed, until mycelium is clearly growing.
4. Break and shake. At about 25–30% colonization, gently break up and massage the grain to spread the mycelium, then let it finish colonizing.
5. Spawn to bulk. Once the bag is fully white, break it up and mix it evenly into pasteurized bulk substrate in your monotub.
