‘Boomr Bag’ Manure-Based Sterile Mushroom Bulk Substrate

Improve the yield of any dung-loving mushroom species with our best-selling Boomr Bag! This sterile bulk mushroom substrate is formulated by mycologists and 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 a wide range of dung-loving mushroom species and is widely-trusted by mushroom growers. Note: Substrate is hydrated to field capacity. Use your Boomr Bag in monotubs, outdoor beds, or to grow mushrooms from the bag in a humidity-controlled grow room or Martha setup! We recommended 1 lb of colonized grain spawn for every 5 lbs of Boomr Bag sterile substrate. (Higher inoculation rates may improve your success.) Looking for bulk packs? Click here.
