## Overview

North Spore’s 3lb Organic Hydrated Sterilized Grain Bag features a USDA certified organic millet and wheat blend, hydrated to 50% moisture for optimal mycelium colonization. Equipped with a self-healing injection port and a 0.2 micron filter patch, it ensures sterile inoculation and gas exchange. Commercially autoclaved and ready to use, this spawn bag is designed for fast, contamination-free mushroom cultivation.

## Description

Our premium organic sterilized grain bag was formulated by mycologists to maximize the speed and size of your mushroom grow. Each spawn bag contains our proprietary blend featuring hydrated, nutrient-rich organic millet and wheat berries. Bags also include a self-healing injection port for use with a spore or culture syringe plus a 0.2 micron filter patch to block airborne contaminants while providing even gas exchange. (Note: Color of injection port may vary.) MIXING WITH SUBSTRATE We recommended 1 lb of colonized grain spawn for every 5 lb of manure or hardwood substrate. INOCULATION To inoculate the grain bag, simply inject your spore or culture syringe through the port in a sterile location. We always recommend clean hands and latex gloves to reduce the introduction of contaminants. (It is best practice to wait a minimum of 1 week after arrival before injecting grain bags to ensure they were not compromised during transit.) COLONIZATION Allow your bag to colonize in a cool location out of direct sunlight. The temperature for incubation shouldn't exceed 75 degrees F or dip below 55 degrees F. After a couple of weeks, you should start to see mycelium growing on the grain. You'll notice the white mycelium growing outward from the injection point. When it has grown three to four inches you should, without opening the bag, carefully break up the colonized grain and mix it into the uncolonized grain. This will dramatically speed up the colonization process. When the bag is completely white with mycelium your spawn is ready to use. This may take a couple of weeks to a month or more depending on the species and vigor of your culture. STORING Grain bags should be stored at room temperature out of direct sunlight. No refrigeration is necessary. They can also be stored for several months before use. STERILIZATION Our grain spawn bags are sterilized in a commercial-grade autoclave. Sterility is verified using biological indicators and temperature sensors.

Review: Self healing injection port is working solid, no contams 3 weeks post injection- which also points to the fact that they autoclaved this thing well. It's been well over a month since I got it and that means it's probably been a month and a week since it was packed. The price is a steal for the work I avoided, and considering how little output I do it's just easier. North Spore is solid and they've been in the game for years, I wouldn't shave off a couple dollars to get a version that I would even have to worry about mold with. It was good to go out of the box, just unfold it gently and don't get your filter wet. I don't know if it's waterproof, I always assume no. Oh, no big moisture spots or visible dryness either if you're worried about that.
Review: This sterilized, hydrated grain spawn bag worked perfectly for my lion’s mane mushroom grow! It arrived well-sealed, clean, and fully hydrated—ready to inoculate right out of the box. Colonization was fast and even, and I got a great yield. Super convenient and reliable for home cultivation. Highly recommend for any mushroom grower!

Haven't had a problem with a bag yet! I've been able to colonize and spawn to bulk with every single one. I will say this, North Spore is a brand i trust. There's plenty of other bigger and cheaper grain bags on here..but I know this works, it's clean, and if there is ever a problem, North Spore will take care of it. Not if you inoculated and nothing grew...im talking about if the grains don't look right, the bag isnt vacuum sealed, or it smells bad. Quality is 10/10. It does its magic thing every single time :)
