Get 5 Free Agar Plates (random color) with the purchase of a Pre-Sterilized Grain Bag.

These bags are full of hydrated and sterilized 50/50 mix of millet bird seed and oats. Use the Agar Plates to germinate spores or expand your existing cultures. Once they're ready to go you can inoculate your grain bag and get ready for bulk. 

Injection ports are included at no extra charge. Every grain bag is made to order. Please allow 24-48 hours before grain bag orders are shipped. 

What is a grain bag?
Grain bags are the first step in growing from either a multi-spore syringe or liquid culture. Once your grain bags are fully colonized, the next step is to mix them in with the substrate. Your substrate will consist of either wood sawdust, compost, manure or cocoa coir. We also sell substrate bags here under Growing Supplies. 

How to inoculate at home
We've created a simple video that discusses how to use our agar and grain bags. Watch it here. 

Wanting to improve your chances of success? 
If you're starting from a multi spore syringe it's best to start them on agar first. Agar gives you the ability to visually see any contaminants. From there you can transfer chunks of good mycelium to more agar plates. After a few days you'll see the healthy mycelium will expand on the new plates. You can repeat this until you have a healthy monoculture of your desired fungi. The process of isolating away from contaminants can take some time but it guarantees your success in growing mushrooms. You can purchase a 10 pack of ready-to-use agar plates here. 

We've combined everything you need in one complete kit to grow dung loving species like Agaricus "white button" and others. This simple and easy to use kit was designed for beginners. It does not require clean room conditions at each stage of the process (general cleanliness is still required).

Simple and Effective Process

• Simply inject the bag with your own multi-spore syringe or liquid culture.
• After 2-8 weeks the grain will be consumed by mycelium and ready for transfer to bulk substrate. 
• Mix both the grain and substrate bags in the plastic box and cover with lid. 
• After 2-3 weeks the substrate will be completely colonized and ready for fruiting. 
• Remove the lid, mist with distilled or boiled water, fan and place the included 2nd container on top. The tiny gap between the boxes is important for air flow. 
• Mist and fan 2 times per day to encourage fruiting. 

What's Included:

• 3lb Sterilized Grain Bag with Injection Port - The bag contains hydrated grain that's been sterilized. Sterilizing is extremely important to ensuring only your intended fungus is growing. An injection port is included to provide a clean way of transferring sterile multiple spore solution or liquid culture. 
• 5lb Sterilized Manure Based Substrate - This substrate is made up of cow manure, coco coir and vermiculite with a the perfect amount of water. It's pasteurized via steam for 16 hours to ensure all living organisms are destroyed. Doing this helps to ensure your success in growing mushrooms instead of mold.
• 2 - 6qt Plastic Boxes - These are simply small plastic totes. No need to add any unnecessary complexity to this. It works well as a container for the colonizing substrate and to provide a simple fruiting chamber. 
• Misting Bottle - Be sure to use only distilled or boiled water. This is important since most tap water contained chlorine which can kill fungi.  
• 1 Lid - Just a simple lid. However, we recommend covering the plastic container with foil first to create a better cover with minimal air exchange. The lid adds protection.
• Black Plastic Liner - One issue with growing mushrooms in containers is they love to grow between the substrate and container. The liner blocks the light and discourages mushrooms from forming from anywhere but the top. 

As you can see we've include everything you need and nothing you don't!
