The Six Substrate Jar Upgrade Option

Another great way to grow mushrooms is to use substrate jars. You have a smaller area to produce the mushrooms when compared to a casing method but you can also stack the colonized cakes up into a pyramid structure and utilize the entire growing area inside the dome.

Half pint, PF style substrate jars are a great way to grow mushrooms.

The substrate jars are made with durable plastic that can withstand the heat and pressure of an autoclave so it makes them easier to work with and less weight than the common glass jars. They are also slightly larger than the average half pint glass jars so you get an approx. 2oz more substrate included with each jar.

Only the highest quality organic ingredients are used to make the Mushbox™ substrate jars. You can learn more about this product and purchase larger amounts at the www.mushbox.co website.

The substrate jar upgrade includes: • 12 - Half pint PF style substrate jars. Get this upgrade by itself for $62.99.
