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.

North Spore's products shall be used only for lawful purposes. North Spore does not condone Psilocybin (Psilocybe cubensis) or hallucinogenic (magic) mushroom growing in jurisdictions where it is currently illegal.

Great Sub!

Very nice sub, I got four zips off of the first flush. I had an issue with a bag, customer service was great, and they sent me a bag out asap.

A gift for a friend

My friend was super excited to see how well this substrate performed! The growth rate and vigor of the mushrooms is exceptional. He has had no issues with contamination. It will be fun to enjoy some mushrooms with him once he is able to harvest them.

As far a manure goes... this was perfect.

The items are always as described and if there are ever any issues (which are bound to happen in this industry) the customer service is where North Spore shines.
