- GROW BIGGER FLUSHES: Our best-selling Boomr Bag is a sterile manure-based bulk mushroom substrate formulated by mycologists to maximize your mushroom yield. 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.
- PERFECTED FOR DUNG-LOVING SPECIES: It features a proprietary blend of composted horse manure, coco coir, and several quality substrate supplements (although we keep the exact blend a secret!)
- MIX WITH COLONIZED GRAIN SPAWN: We recommended 1 lb of colonized grain spawn for every 5 lbs of Boomr Bag sterile substrate. (Higher inoculation rates may improve your success.)
- STORE UNTIL READY: Boomr Bags can be stored for several months before use. They should be stored at room temperature out of direct sunlight. No refrigeration necessary.
- TRUSTED BY GROWERS: Our Boomr Bags are sterilized in a commercial-grade autoclave. Sterility is verified using biological indicators and temperature sensors.
- BEST PRACTICES: We recommend clean hands, latex 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.
