3lb Organic Wild Oats Grain Bag

Our best-selling nutritious mushroom spawn bags are the perfect solution for anyone looking to grow their own mushrooms at home or on a small scale. These bags are filled with a mixture of sterilized grain and our proprietary blend of nutrified water that provides a nutrient-rich environment for mushroom growth.

The bags are made from high-quality, breathable material that allows for proper air circulation and prevents contamination. They are also equipped with a self-healing injection port, making it easy to introduce additional spores or nutrients as needed. The water we use to soak and boil our oats is enhanced with a natural pH balancer, calcium supplement, and a full spectrum micro organism starter. Our spawn bag contains sterilized hydrated wild oats sourced from the farmlands of Ohio. Each bag comes with a 0.2-micron filter patch to block airborne contaminants while allowing even gas exchange with the option of a self-healing injection port to use with a spore or culture syringe.

To use the spawn bags, simply follow the included instructions and watch as your mushrooms grow and flourish. Whether you are a seasoned mushroom grower or a beginner, our spawn bags are easy to use and provide excellent results.

In addition to being a convenient and reliable way to grow mushrooms, our spawn bags are also environmentally friendly. They can be used to grow a variety of different mushroom types and provide an alternative to traditional growing methods, which can be resource-intensive and damaging to the environment.

With our mushroom spawn bags, you can enjoy the delicious and nutritious benefits of homegrown mushrooms anytime, anywhere. So, it is a perfect choice for mushroom lovers.

We recommend a 1:1 ratio of colonized grain spawn to your choice of substrate. We also recommend using 3 - 5ccs per 3lb injection port bag.
