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.
