All-in-One Bulk Monobag Kit

Go From Jar to Bulk Harvest—The Easy Way!

Take the next big step in your mushroom-growing journey with the All-in-One Bulk Monobag Kit—a beginner-friendly path to high-yield, bulk fruiting. Perfect for growers who have mastered jars and are ready to scale up, this kit makes the transition to bulk incredibly simple. Just inject your spores into the grain jar, let it colonize, then mix with the Select Casing Mix inside the heavy-duty Monobag—and watch your mushrooms take off!


What’s Included:

  •     30oz 5-Grain Jar
        Pre-sterilized with a self-healing injection port—ideal for fast colonization.
  •     5 lb Midwest Select Casing Mix
        A professional-grade blend of coir, vermiculite, and pH buffers—pre-pasteurized and moisture-balanced for explosive growth.
  •     12"x8"x20" Gusseted Polybag (8mm)
        Heavy-duty, self-supporting bag with pre-cut 1.66" holes for filter placement.
  •     2x 2" Monotub Filter Disks
        Easy peel-and-stick filters provide optimal air exchange while keeping contaminants out.
  •     Spray Bottle
        Maintain the perfect humidity with targeted misting.
  •     2 Bag Clamps
        Secure your bag during colonization and fruiting stages.

Why Choose the Monobag Kit?

  •     Grow 5–10x More Than a Standard Jar
        Upgrade to bulk without needing a full monotub or greenhouse setup.
  •     Simple 2-Step Process
    1.    Inoculate the jar. 2. Mix with the casing mix in the Monobag.
  •     No Special Equipment Needed
        Everything is included—even misting tools and air filters.
  •     Fast Setup, Fast Results
        Colonization typically completes in 10–14 days after mixing with substrate.

All in one Bulk mono bag review

First off Midwest grow kits is my go to and should be everyone?s in my opinion! That being said this is a limited review because I?m still in inoculation. Just began actually but my 5grain jar is already showing mycelium growth within just two days. Seems like it?s going to be a really great experience, maybe an update when I make exchange from jar to mix/mono bag, possibly! Thank you MWGK! Still no negative experiences through all my purchases, one broken item in shipping is all but not MWGK fault and they fully replaced it for free and have helped in other ways too. Great Support staff as well! You?ll never not be able to have a question go unanswered if you email them, very fast responses.

Great kit for beginners or small growers

I almost didnt have any mushrooms due to me misunderstanding the instructions and over watering during incubation, but this kit is pretty foolproof and allowed me to recover. After getting my bag moisture in check the bag is now flourishing, and will soon be ready for harvest. While I plan on upgrading to a monotub grow, i'm going to do another few bag kits before moving on.

Easy to use grow kit in a bag!

Great grow kit in a bag. I like the ease of use. Good quality grain/grain jar. The grow bag quality is exceptional. My 1st kit provided me with 50 grams of dried mushrooms, 3 flushes. I would recommend!
