For absolute beginners, start with an automated monotub system

Start growing your own edible or medicinal mushrooms indoors. (All that's required is a spore syringe or liquid culture!) We designed this monotub kit specifically for beginners, pairing our beginner-friendly CVG bulk substrate with our Boomr Bin, coco coir, monotub filters, and Bin Tech Kit to make your first growing experiences more successful. When used with sterile technique, this combination is less likely to contaminate vs. using a more nutrient-rich substrate.

CVG is known for yielding consistent, dependable flushes. By using less substrate (2 bags instead of 3) you will get a higher inoculation rate, increasing colonization times and decreasing the chances of contamination. (Once you’re ready to level up, you can switch to Boomr Bag substrate for bigger yields)

About the monotub:

The patent-pending Boomr Bin 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.

Automated monotub kit includes:

• (1) Boomr Bin monotub
• (1) FAE Fan Mini w/ power control
• (1) Myco-Mister Mini humidifier w/ hose
• (1) Monotub hose connector
• (1) Mycontroller humidity controller (hygrometer)

Substrate kit includes:

• (2) CVG sterile bulk substrate (5 lbs each)
• (1) Sterilized grain bag with injection port (3 lbs)
• (1) Myco Coco compressed coco coir (3.4L)
• (1) Sheet of 1" monotub filters
• (1) Sheet of 2" monotub filters

About the substrates:

Our CVG, sterilized grain bag, and coco coir are three growth mediums for colonization, incubation, and growth. The sterilized grain bag is first inoculated with your spores or liquid culture syringe to create spawn. The CVG is then mixed with your spawn for colonization.

Finally, once your monotub is colonized, coco coir is added as a casing layer to provide moisture retention, even gas exchange, and an optimal pH. We've also added two sizes of self-adhesive filters designed to keep our foreign spores and other contaminants while maintaining proper humidity, airflow, and gas exchange. 

Boomr Bin features:

• Modular design accepts automated air exchange and humidification systems. 
• Food-grade materials FDA-approved for contact with consumables.
• Compact durable design holds up to 20 pounds of substrate.
• Latches attached to base to prevent lid from popping off when picking up.
• Extra large latches with recessed grips for easy lifting and transport.
• Large rounded corners for easy cleaning and fewer places for contaminants to hide.
• Row of 1” holes placed lower in the lid to prevent fuzzy stems.
• Black light-blocking base helps colonization and aids in preventing side pinning.
• Modular design accepts automated fresh air and humidity systems.
• Dimensions: 22”(W) x 15”(D) x 11”(H)

Spawn to bulk ratio:

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

Optional add-ons:

• Monotub liners

Important notice:

Coco coir should only be added once the Boomr Bin is fully colonized and pins begin to form. Only a thin layer of coco coir (approx. 1/2 inch) is needed. 

⚠️ Using tap water with a high mineral content (aka "hard water") with any humidifier can cause a fine white dust build to up and/or to be emitted. To avoid this, use distilled or demineralized water. Or, add a demineralization cartridge to the water tank. (This can be done by removing the top cover and placing the cartridge inside.)
