Boomr Bag’ Manure-Based Sterile Mushroom Bulk Substrate

Maximize your mushroom yield!

Our best-selling Boomr Bag is a sterile manure-based bulk mushroom substrate formulated by mycologists to increase the yield of your grow. Over several years, the recipe has been perfected for dung-loving mushroom species and is widely-trusted by mushroom growers. Use Boomr Bag in monotubs, filter bags, and outdoor beds. Or, grow mushrooms from the bag or in a tray using a humidity-controlled grow room or Martha set up.

Features & benefits:

• Made entirely from organic materials
• Balanced pH with a complex nutrient profile
• Proven vigorous mycelial growth
• Fast colonization and higher yields
• Increased aeration and moisture retention 
• Hydrated to field capacity

Boomr Bag is made from a blend of quality local, organic, and non-GMO materials including a proprietary blend of composted horse manure, coco coir, and several quality substrate supplements (although we keep the exact blend a secret!) Unlike other substrates that contain harmful additives, you can rest assured that your grow will be natural and chemical free.

Spawn to bulk ratio:

We recommended mixing 1 colonized grain spawn bag with 2-3 Boomr Bags. (Higher inoculation rates may improve your success.)>
