North Spore Boomr Bag Sterilized Manure-Based Mushroom Substrate

Increase your mushroom grow with North Spore’s manure-based substrate, specially designed by mycologists for maximum yield.

North Spore's 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 they 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.

Each Boomr Bag is sterilized in a commercial-grade autoclave to preserve your sterile work space. Sterility is verified using biological indicators and temperature sensors.

Features

• Specially formulated substrate mix
• Helps dung-loving mushroom species achieve maximum yields.
• Professionally sterilized to reduce contamination risk.

Spawn to bulk ratio:

We recommended mixing 1 colonized grain spawn bag with 2-3 Boomr Bags. (Higher inoculation rates may improve your success.)

Best practices

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.

Storing

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.

Sterilization

Our Boomr Bags are sterilized in a commercial-grade autoclave. Sterility is verified using biological indicators and temperature sensors.
