The same Unicorn medium bag, by the case.
This is the full factory case: 1,000 Unicorn medium 10T bags, the same 5" x 4" x 18" gusseted bag as our 50-pack at case pricing. At 3 to 4 pounds of grain per bag, one case runs roughly 3,000 to 4,000 pounds of spawn, which makes it the right buy for farms, labs and spawn producers filling bags every week.
Unicorn bags are made in the USA by the company that created the filter patch spawn bag. The film carries pliability additives so it stays flexible after sterilization instead of stiffening, and the bottom seal is built to hold up to the shaking a grain run takes.
The lowest cost per bag for growers who run grain continuously.
Every bag in the case is the same format, so your fill weights and sterilization times stay consistent.
A case keeps production moving instead of waiting on the next 50-pack.
Add 3 to 4 lb of hydrated, drained grain. Keep wet grain off the filter patch.
Fold the top over and clip it. The bag needs to vent during sterilization, so don't heat-seal it yet.
Pressure sterilize at 15 psi, typically 90 minutes to 2 hours. Keep bags off the bottom of the pot and away from the heating element.
Let the bag cool to room temperature, inoculate in clean air, then heat-seal and incubate.
Inoculating more than once? Add a self-healing injection port before sterilizing so you can inject spores or liquid culture without opening the bag.
Need to fruit right in the bag? Blue Myco XLS double patch fruiting bags have two larger 0.5 micron patches for the extra air exchange a fruiting block needs.
Complete the setupFill your bags with bulk rye berries, close them with the PFS-300 impulse sealer and sterilize in a pressure sterilizer. Rather skip the prep? Our sterilized spawn bags come ready to inoculate.
Yes. It is the identical Unicorn medium 10T bag, packed as a full 1,000-bag case.
At 3 to 4 lb of grain per bag, roughly 3,000 to 4,000 lb of spawn.
Yes. That's what they're made for. The polypropylene stays flexible through the cycle. Fold the top instead of sealing it so the bag can vent, and keep bags off the bottom of the pot.
Inject through the filter patch with an alcohol-wiped needle for a single entry. If you'll inject the same bag more than once, add a self-healing injection port.
They're bag format names, not thickness ratings. 10T is the medium 5" x 4" bag and 3T is the large 8" x 5" x 19" bag. Check the film column above for thickness.
