Our discount grain spawn is grain spawn that is several weeks old and ready to ship immediately. Sometimes we produce extra spawn, and these bags are discounted because they are not made to order. 

What is grain spawn?

Grain spawn is a container of grain with living mycelium that has colonized each kernel of grain. The grains are simply seeds, usually the same seeds used in agriculture. We're not talking about common edible kernels like rice and corn here; we're talking about wheat, rye, millet, milo: the starchy substance that fills up the space inside these seeds is perfect food for mycelium.

Grain spawn is usually pure white, but sometimes pink, tan, grayish--it varies depending on the type of grain used and how fully it was colonized by the individual mushroom species and variety. Appearance could vary based on many factors.

When is grain spawn used?

Grain spawn is essential for growing mushrooms. The purpose of grain spawn is to act as a culture used to inoculate other substrates. This can be done by mixing into the substrate, otherwise known as inoculation.

  • 1st generation (G1) grain spawn can be used to inoculate other grain spawn, also known as G2 or 2nd generation grain spawn.
  • 2nd generation (G2) grain spawn should only be used to inoculate sawdust-based substrate materials.

Grain spawn will usually colonize any substrate within 7-14 days if used properly.

How long does grain spawn last?

Grain spawn should be used as quickly as possible. Storing in refrigerated conditions until use is ideal.

What's in the stuff?

We use a blend formulated to increase rapid mycelium growth in your substrate. The formula we use is a proprietary blend of locally produced wheat seeds with a 10% sawdust based supplement that varies slightly for each species of mushroom.

My dog likes it!
Size: Medium, Color: Antler, Size: Medium, Color: Antler
My aggressive chewer loves it! I have a 20 pound rat terrier ....small was recommended, but we went with a medium. He went to work on it right away. He is not picky about chew bones but it makes me feel better that it is a natural material. The chewed photo is about 30 mins after giving it to him.

Not for us!
Size: Large, Color: Antler
I'm sure for a dog that doesn't chew, would be great. Ours went through it in days, leaving sharp shards and making his gums bleed.

Power Chewer Loves This!
Size: Medium, Color: Antler
This is my dog's new favorite chew! She loves that she can hold it in her paws. I think she really loves the taste and texture of it. I don't give her antlers as I have heard too many horror stories about broken teeth. I also don't give her nylon toys as I have also heard a lot of horror stories of broken teeth as well as concerns about them digesting the plastic. This is between antlers and bully sticks, which is perfect for a power chewer. I feel comfortable with her eating the pieces that flake off this toy. She loves chewing and she will default to this toy when she wants to help calm down. I don't notice much of a smell. It does flake, but not enough I will even take a star off. Plus, it's plant based and vacuums up easily once dried. It doesn't capture her attention as much as bully sticks or beef cheek chews, but it's much less expensive over time and doesn't stink up our living room! She will also always pick this over any of her rubber chews. Great product and recommend it for all the power chewers.
