Our best-selling Boomr Bag is a sterile bulk mushroom substrate formulated by mycologists to increase the yield of your grow. It features a proprietary blend of composted horse manure, coco coir, and several quality substrate supplements (although we keep the exact blend a secret!) Over several years, it has been perfected for dung-loving mushroom species and is widely-trusted by mushroom growers. Note: Substrate is hydrated to field capacity.
Use your Boomr Bag in monotubs, outdoor beds, or to grow mushrooms from the bag in a humidity-controlled grow room or Martha setup!
Spawn to bulk ratio
We recommended 1 lb of colonized grain spawn for every 5 lbs of Boomr Bag sterile substrate. (Higher inoculation rates may improve your success.)
-
- We recommend clean hands and latex gloves when using Boomr Bag to reduce the introduction of contaminants.
- Be sure to mix colonized grain spawn thoroughly into your substrate.
- It is best practice to wait a minimum of 1 week after arrival before using sterile substrates to ensure they were not compromised during transit. Rest assured that your purchase is 100% guaranteed. If your substrate was compromised, we will replace it.
-
Boomr Bags should be stored at room temperature out of direct sunlight. No refrigeration is necessary. They can also be stored for several months before use.
-
Our Boomr Bags are sterilized in a commercial-grade autoclave. Sterility is verified using biological indicators and temperature sensors.

Boomerbag = Boom yay!
Never had an issue with this substrate. I’ve tried a few different brands, but none have given me the results that North Spore’s Boomerbags have. Those results being good. Grab a boomer bag if you want and explosion of growth. BOOM! 10/10
