'Boomr Bag' Sterile Manure-Based Mushroom Bulk Substrate
Zoom
| Media | Horse manure mix |
| Moisture content | Hydrated to field capacity |
| Bag weight | 5 lbs |
Our best-selling Boomr Bag is a sterile bulk mushroom substrate formulated by mycologists to maximize your mushroom yield. 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!
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.

United StatesAmazing
I did the whole Coir with perlite and vermiculite deal with positive results. But I figured I would splurge on this and give a try. Never looking back. This was so easy and worked amazingly. mycelium started growing withing 24 hours and has been steady, strong and bold. Fruit is exploding and I am excited to see how many decent flushes I can get out one bag. This thing pays for itself.

I like this substrate because it is free of vermiculite and works great. You dont need to add anything. High yield. Best I have used. I won't buy anything else. You should definitely try it.
