North Spore ‘Boomr Bag’ Manure-Based Sterile Mushroom Bulk Substrate - Pallet of 336

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 your Boomr Bag in monotubs, outdoor beds, or to grow mushrooms from the bag in a humidity-controlled
grow room or Martha setup!
