GROW A WIDE RANGE OF SPECIES: Ideal substrate for any mushroom species that prefers a nutrient rich media - perfect for Agaricus sp. EASY TO USE: We have done the hard work for you. With this sterilized blend you simply mix in mushroom spawn and watch it grow. Ideal for mono-tub production methods. PRODUCED IN A STATE OF THE ART FACILITY: North Spore is a full service mushroom spawn company that supplies farms across the country. All of our spawn and mushroom substrates are produced by a team of lab technicians utilizing a strict quality control protocol.

  • INCREASE YOUR YIELD: Our best-selling Boomr Bag is a sterile manure-based bulk mushroom substrate formulated by mycologists to increase the yield of your grow.
  • PREMIUM MANURE BLEND: It features a proprietary blend of composted horse manure, coco coir, and several quality substrate supplements (although we keep the exact blend a secret!)
  • TRUSTED BY GROWERS: Over several years, Boomr Bag has been perfected for dung-loving mushroom species and is widely-trusted by mushroom growers. Note: Substrate is hydrated to field capacity.
  • FOR EVERY TYPE OF GROWER: 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.)
  • STORAGE: 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.
  • BEST PRACTICES: We recommend clean hands, latex or nitrile gloves, and sterile technique when using Boomr Bag to reduce the introduction of contaminants. It is also best practice to wait a minimum of 1 week after arrival before using sterile substrates to ensure they were not compromised during transit.
