Unicorn 10T INJ — Mushroom Grain Spawn Bag (Medium) w/ Injection Port

The Unicorn 10T-INJ is the same workhorse 10T grain spawn bag with a factory-fitted self-healing injection port built in — up to 1.8kg per bag, ready for syringe inoculation straight out of the bag. The same 0.2 micron T filter as the 4T-INJ, scaled up. Made in the USA since 1990 by Unicorn Bags LLC, the industry's most trusted name in mushroom cultivation bags.

Why growers choose the 10T-INJ

• No need to fit your own injection port or self-heal patch — it's built in at the factory
• Same trusted 0.2 micron T filter as the 4T-INJ with up to 80% more grain capacity per bag
• Fewer bags per batch means less handling and a faster workflow
• Handles full autoclave cycles at this weight without seal failure or warping

Need a smaller bag? The 4T-INJ holds up to 1kg with the same injection port. Don't need a port? See our standard 10T.
