## Description

desertcart.com : North Spore Organic Sterlized Mushroom Spawn Bag, 1 Pack | Sterlized Grain Bag with Millet & Wheat Berries, USDA Certified Organic, Self-healing Injection Port, 0.2 Micron Filter Patch : Patio, Lawn & Garden

Review: Trustworthy Bag - 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: piece of mind with this product - seems to be working great. I tried to make my own at home but couldn't get it right. much easier to buy from these guys and know that it will work with no problems. mushrooms colonized great. good value for the money and even the appearance of the bag and shipping box shows care.

## Features

- FORMULATED FOR A BETTER GROW: Our organic sterilized grain bag was formulated by mycologists to maximize the speed and size of your mushroom grow. (All that's required is a spore syringe or liquid culture!)
- NUTRIENT-RICH BLEND: Each spawn bag contains our proprietary grain blend featuring hydrated, nutrient-rich, organic millet and wheat berries.
- MORE INOCULATON POINTS: Millet has a much lower endospore load than rye and wheat, making it less prone to contamination. And its small size means your spawn will have many more inoculation points for the same volume of grain.
- JUST ADD SPORES: 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.)
- QUALITY YOU CAN TRUST: North Spore grain spawn bags are sterilized in a commercial-grade autoclave. Sterility is verified using biological indicators and temperature sensors.
- SPAWN TO BULK RATIO: We recommended 1 lb of colonized grain spawn for every 5 lbs of manure or hardwood sterile substrate. We also recommend using 2.5-5ccs per 3 lb injection port bag. (See Inoculation and Colonization below for full details.)

### ⭐⭐⭐⭐⭐ Very convenient!
*by C***E on July 29, 2026*

Loved how convenient it was to just inject in the bag and it was already sterile and ready to go. Of course you still need to sterilize around you and wear gloves but it came out perfect for my first time trying it
