Grains are an awesome choice for growing mushrooms. They take mycelium well and will spread evenly. Depending on conditions such as temperature, humidity, and other factors, mycelium will be able to spread in as little as a week. Our grain bag comes equipped with a self-healing port making injections easy and reliable. Additionally, the 0.2 micron patch allows for better breathing and overall better growth. Starting off right is one of the most important factors for mushroom growing! Our grain bags can be a great start!

HEALTHY, WELL-HYDRATED & STERILE. The grains have a great balance of hydration making it great for mycelium growth. We sterilize the grain bag to make sure it gets to you in the best condition possible.
FASTEST MYCELIUM COLONIZATION. Our grains have been shown through both tests and satisfied customers to produce great mycelium growth. Grains are a great medium for colonizing, and we highly suggest trying it out!
SELF-HEALING INJECTION PORT & 0.2 MICRON PATCH. Self-healing injection ports are important because they give you more confidence in your growth. They are more reliable compared to bags without ports. Each bag has a premium quality 0.2 micron patch that will allow your mycelium spawn to breathe and grow better.
EASY TO USE AND MINIMAL PREP WORK. The grain bags are extremely simple to use and require very little to start. Simply use a syringe to inject liquid mushroom culture into the self-healing injection port. Place in a dark location preferably 70°F- 80°F. Soon your grains will develop mycelium and spread completely throughout the bag. Then, your spawn will be ready to use!
PROFESSIONALLY PREPARED & HIGH QUALITY. We prepare our product so you are guaranteed the highest quality when using your grains.
