All-in-One Mushroom Grow Bag (5 lbs) for Manure Loving Mushrooms

Our All-in One or "AIO" grow bag is a beginner friendly and easy way to grow manure/dung loving mushrooms right at home. It comes filled with sterilized grain and premium, organic substrate. Each bag can grow 30+ ounces of fresh mushrooms.

Why use our All-In-One Mushroom Grow Bag: 

1. No Contamination Most people fail at mushroom growing because of contamination. We sterilize our bags for 3 hours at 20 PSI in a commercial autoclave. That means when your bag arrives, it’s a biological clean slate. You don’t need a clean room; just need a kitchen counter.

2. Perfect Blend Our mix uses high-quality, locally sourced millet for rapid colonization and CVG+ for heavy flushes. It’s hydrated to the exact milliliter so you don't have to worry about wet rot or dryness.

3. Pro Grade Our bags feature a self-healing injection port (so you don't let in bad air) and a professional-grade 0.2-micron filter patch. Your mushrooms can breathe, but the mold can't get in.

How it Works: 

We’ve designed this bag to be a self-contained ecosystem. Just follow these five simple steps:

1. Inoculation Using the self-healing injection port, introduce your spore syringe or liquid culture.

2. Grain Colonization Place the bag in a dark, room-temperature spot. Over the next couple weeks, you’ll see bright white mycelium begin to "take over" the nutrient-rich millet at the bottom. This is the engine of your grow getting started.

3. Break & Shake Once the grain at the bottom is fully white, gently break it up and mix it into the organic coconut coir and worm casting substrate above. 

4. Fruiting When the entire bag has turned white, your mushrooms are ready to meet the world. Cut a small slit in the bag to allow for gas exchange. This simple change in oxygen levels acts as nature’s alarm clock, telling the mushrooms to start pinning.

5. Harvest & Rehydrate Once the caps are ready, harvest your mushrooms! But don't throw the bag away, soak the substrate block in water for a few hours to rehydrate it. Most of our growers enjoy 2–3 heavy flushes from a single bag.

What's in it

• 2 lbs Hydrated Millet: The primary energy source. Its small size provides thousands of inoculation points, leading to faster colonization than larger grains.

• 2 lbs Coconut Coir: A clean, sustainable substrate that holds massive amounts of water while maintaining structure for mycelium to crawl through.

• 0.5 lbs Worm Castings: Nature's fertilizer. It provides essential nitrogen and micronutrients that lead to larger, more potent flushes.

• 0.5 lbs Vermiculite: Acts like a sponge to keep the bag hydrated throughout multiple flushes, preventing the substrate from drying out.

• 20g Oyster Shells: Provides a slow-release calcium boost and helps buffer the pH level to keep the environment slightly alkaline, which mushrooms love.

• 20g Gypsum: Provides essential calcium and sulfur for cell wall development.

• 20g Azomite: A volcanic mineral dust that provides over 70 trace minerals, ensuring the mushrooms have everything they need for optimal health.
