Maximize your mushroom yield!
Our best-selling Boomr Bag is a sterile manure-based 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 Boomr Bag in monotubs, filter bags, and outdoor beds. Or, grow mushrooms from the bag or tray in a humidity-controlled grow room or Martha set up.
Spawn to bulk ratio:
We recommended mixing 1 colonized grain spawn bag with 2-3 Boomr Bags. (Higher inoculation rates may improve your success.)
-
- We recommend clean hands, latex or nitrile gloves, and sterile technique 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.

Unfortunately wasn’t able to use the substrate the way I intended, the field capacity seemed way to moist but I used it anyway hoping it would be alright but it contaminated right away. It’s very possible the contam came from something I did or didn’t do. But I love north spore and would recommend them regardless of this last experience.

We're so glad everything is working out for you, John! Thanks for the great review.
Great!
I am getting into mycology. My previous grows used coir. Which worked fine. However, I didn't like the process of sterilizing the substrate so I looked for other ways. I also wanted to try manure instead of Coir. So far the first flush is better than last time and I didn't need to get too dirty! I will report back when the grow finishes. I think perhaps that using manure might yield slightly more due to the nutrition. However, I am not sure how much of a factor it is.
