North Spore's 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 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 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.
