Grow Strong and Healthy Mycelium!
Discover the Secret to Successful Mushroom Cultivation
Ready to grow strong and healthy mycelium with ease? Our Mason Jars provide the ideal sterile environment for your mycelium to thrive, helping you achieve robust growth and set the stage for a successful mushroom harvest.
Why Choose Our Mushroom Grow Jars?
1. Highlight Durability
The jars can safely withstand up to 15 psi, making them suitable for both steam sterilizing and pressure cooker sterilization. This durability ensures reliable use over time without the risk of cracking or breaking under high pressure.
2. Low Contamination Rates
Using self-healing injection ports allows for spore-to-agar transfers with a 95 percent success rate. This design minimizes the risk of contamination, giving you more consistent and reliable results with every use.
3. Beginner Friendly
The jars can be used with little to no additional equipment, so even beginners can start growing without a pressure cooker. Their simple design makes the process straightforward and easy to follow, reducing the chance of mistakes.
4. Perfectly Sized
Each jar provides plenty of space for grain, which produces enough mycelium to support a dense pin set in your monotub. This ensures strong, healthy growth and maximizes the yield from each batch.
5. Rust Protection
The holes in the jars are coated with 99 percent zinc to prevent rust over time. This added protection helps the jars last longer and maintain their quality even with repeated use.

1. How to Use Mason Jars to Grow Mushrooms?
1. How to Use Mason Jars to Grow Mushrooms?
You use mason jars as part of the growing process. They provide a clean and controlled environment where the mycelium can develop safely before being transferred to the substrate, where the mushrooms will eventually grow.
2. What is the Recommended Grain Fill Level for Optimal Mycelial Growth?
2. What is the Recommended Grain Fill Level for Optimal Mycelial Growth?
It’s best to fill the jars to about 75% of their capacity. This leaves enough space to break up the mycelium later, which significantly increases the growth speed.
When the jar is about 30–40% colonized, break up the mycelium to create more inoculation points, allowing it to spread faster.
It’s also a great way to test the strength and health of your mycelium, as only strong cultures will recover quickly.
3. Which Grain Should I Use?
3. Which Grain Should I Use?
You can use a variety of grains such as brown rice, whole oats, rye, bird seed, corn, and many others. There is no single best grain, but some options like brown rice tend to colonize faster than others, which is why we prefer to use brown rice for consistent and reliable growth.
4. How Can I Tell if My Jar Are Contaminated?
4. How Can I Tell if My Jar Are Contaminated?
You can usually tell your jars are contaminated if the growth suddenly stops or the appearance changes, such as turning slimy or showing green or red spots.
Another way to check is by the smell. A sweet, sour, or unusual odor after growth has stopped is a strong sign of contamination. Fresh, healthy mycelium should smell earthy and similar to fresh mushrooms.
5. My Jar is Contaminated. What Should I Do Now?
5. My Jar is Contaminated. What Should I Do Now?
First, do not open the jar indoors to avoid spreading mold spores. Next, throw it away outside in the trash. After that, wash the jar thoroughly with hot water and soap. Finally, sterilize or disinfect the jar, and it will be ready to use again.
