Unicorn Bags 4T is the preferred bag for many growers for their grain spawn. Equivalent comparable to quart jar.

This is because of the 0.2-micron filter versus the standard 0.5-micron filter. So, the 4T is often used for grain spawn by growers who are growing at scale. When spawn in quart jars is not enough, or efficient, you can use these great bags instead.

They allow you better sterilization, and lower risk of contamination when used properly. All of our Unicorn bags are Polypropylene which means they are autoclavable.

You can even save more time with MushroomMediaOnline’s own Fast Fruiting Mix that is that ideal mix of 50/50 hardwood sawdust substrate supplemented with 50% soy hulls.
