Best Mushroom Grow Bags

Frequently Asked Questions

What’s inside your mushroom grow bags?

Our all-in-one grow bags contain sterilized grain and CVG substrate (coir, vermiculite, gypsum), sealed with a self-healing injection port for easy inoculation.

What’s the difference between pasteurized and sterilized substrate?

Sterilized substrate is completely microbe-free and ideal for advanced grows, while pasteurized substrate retains beneficial microbes for natural resistance in bulk setups.

How big is a 4-pound grain spawn bag?

Each 4-pound bag equals about 4 quarts — the perfect amount to inoculate a 5–10 lb substrate bag or a medium monotub.

Can I use your bags for gourmet mushrooms?

Absolutely! Our products work great for oysters, lion’s mane, reishi, most other species as well. Just inject, incubate, and fruit.

Where are your products made?

Every product is made and packaged in a cleanroom environment to ensure consistency, sterility, and peace of mind for every grower.
