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.

This will work but prep is key!
I have an older RV that the gelcoat has dulled and is oxidized, but otherwise in good shape. I have buffed and polished in the past only for it to last a short time. I was looking up different products to try and this one has such good reviews, I thought I would give it a try. I bought the kit with the Poliglow and the Poliprep, with the scrubber and the microfiber glove. I started with the poliprep and it did a great job of gettting the streaks and black marks off. You spend a lot of time scrubbing to your likeness because anything that is still on the gelcoat when you apply the poliglow, it will be locked in there. The Poliglow is like a clearcoat that goes over the gelcoat. You have to build up layers and here are some of the tips and tricks I figured out that really helped my finished RV look great. First, make sure the applicator stays damp, this keeps the poliglow more uniform across the glove. Also, stick it in a zip lock bag when not using, you do not want it to dry out while you are using it. I found out that applying this in direct sunlight in warm temps, is the best method. This allows the poliglow to dry really fast. The first 3 or 4 layers will look streaky and dull but this is ok and as you build up the layers, the shine will come back. I found if you do this when its cooler, the layers do not dry as quick and you will get some permanent streaking or running. I had to remove a section I did in the evening because I noticed this. When in direct sunlight, this gave me the best results with no streaking or running. It dries fast and you can keep working. Like it says, do not do big sections at a time, keep it to small what you can reach sections and build those up and move on. As far as how much to buy? I have a 40 ft toy hauler and I got to kits and I had just enough to finish the whole thing minus the nose cap. I have Durabak on the nose cap, so I dont need to worry about that. I ended up buying one more bottle of the poliglow to have for my maintenance coats. Overall, I am pleased with how my 10 year old RV looks and other than some of the decals show age, it looks new again. If I were to buy a new RV, I would put this on right away and preserve the whole RV including the decals. Its not too expensive and its a lot of work, especially the prep, but it does end up with great results.

Excellent shine
Excellent line of products. Looking at the picture, you can see what the camper looked like before the Poli Glow. To the left of the window is the after Poli Glow. It takes some elbow grease (follow instructions well) but well worth it.

One bottle covered my 20ft camping trailer 4 coats and with a little remaining for future touch ups. It definitely increases the gloss. I'm glad I didn't waste my time with wax. This is like an easy wipe on clear coat. I will report back in the future for longevity.
