Grow your own dung-loving edible or medicinal mushrooms!
Our beginner-friendly monotub kit makes mushroom growing easy. Created by mycologists, this complete starter kit is equipped with everything you need to grow mushrooms at home. (All that's required is a spore syringe or liquid culture!)
The patent-pending design is optimized for all growers – whether you prefer lo-tech grows, or want to connect automated upgrades (like fresh air fans and humidity controls.) As an added bonus, the monotub is made with food-grade materials that are FDA-approved for contact with consumables.
The manure-based sterile substrates, injection port bag, and coco coir provide mediums for colonization, incubation, and growth. We've also included self-adhesive filters that fit over holes on the monotub lid to keep out foreign spores and other contaminants.

Our best-selling Boomr Bag is a sterile bulk mushroom substrate formulated by mycologists to maximize your mushroom yield. 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.
Each bag weighs 5 pounds. (Note: Bags are hydrated to field capacity.) 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.)
Best practices:
- We recommend clean hands, latex or nitrile gloves, and sterile technique when using Boomr Bag to reduce the introduction of contaminants.
- Be sure to mix colonized grain spawn thoroughly into your substrate.
- It is best practice to wait a minimum of 1 week after arrival before using sterile substrates to ensure they were not compromised during transit. Rest assured that your purchase is 100% guaranteed. If your substrate was compromised, we will replace it.
-
Our sterile grain bag with injection port was formulated by mycologists to maximize the speed and size of your mushroom grow. Each spawn bag contains 3 lbs of our proprietary blend featuring hydrated, nutrient-rich organic millet and wheat berries. Bags also include a self-healing injection port for use with a spore or culture syringe plus a 0.2 micron filter patch to block airborne contaminants while providing even gas exchange. Bag weighs 3 pounds. (Note: Bags are hydrated to field capacity.)
Spawn to bulk ratio:
We recommended mixing 1 colonized grain spawn bag with 2-3 Boomr Bags. (Higher inoculation rates may improve your success.)
-
IMPORTANT: Coco coir should only be added once monotub is fully colonized and pins begin to form. Only a thin layer of coco coir (1/4 to 1/2 inch) is necessary.
Coco coir provides many benefits to the mushroom cultivation process. In addition to moisture retention, the porous structure of coir material enables good exchange of air and water and is highly resistant to contaminants making it ideal for mushroom growing. It is often used as casing, added to substrates, and is even used in garden beds as an alternative to peat moss.
-
These self-adhesive filters are sized to fit over holes on the monotub. Use these in place of polyfill to keep out foreign spores and other contaminants while maintaining humidity and air exchange.
- Each 2" sheet contains 6 filters.
- Each 1" sheet contains 12 filters.

Fast and easy
I started a grow with this kit, and in just under a month I had a huge first flush. They've made it simple, easy, and fast. The grain bag colonized fast, the substrate was great and grew fast. The bin itself is a good size, and the rounded corners make it a lot easier to clean than a regular tub.

Super happy w the kit, the substrate is super quality! I could tell the mycelium was absolutely loving it. Quicker colonization & definitely better flush than just CVG. & u dont have to worry about spawn/sub ratio as much tbh Definitely buying more of that substrate until i can start making my own.
