Manure-Loving All-In-One Grow Bag (Shroom Bomb™)

Available Sizes

Each Shroom Bomb™ Grow Bag is available in the following sizes:

• 2-Pound All-In-One Grow Bag

• 4-Pound All-In-One Grow Bag

• 6-Pound All-In-One Grow Bag

Larger bags contain more substrate and grain, which allows for bigger yields and longer production over multiple flushes.

What Makes These Grow Bags Different

These bags are built using our proprietary, manure-loving substrate and grain blend, refined through years of real-world testing.

Each bag contains:

• Premium Milo Grain (replaces oats)

• Coco Coir

• Vermiculite

• Gypsum

Why Milo Grain?

We’ve upgraded from oats to premium Milo grain because it is:

• Smaller and more uniform

• Easier for mycelium to colonize evenly

• Less prone to stalled or patchy growth

• More consistent across flushes

This upgrade improves reliability while keeping the process just as easy for beginners.

Designed for Faster, More Reliable Growth

These All-In-One Grow Bags are structured so that the grain and substrate work together at the ideal time, helping promote faster colonization, healthier mycelium, and stronger overall performance.

The result:

• Faster start-up

• Reduced contamination risk

• Bigger, more consistent mushrooms

And best of all — no extra steps for you. Everything is handled by the design of the bag itself.

Vacuum-Sealed for Freshness & Protection

Every Shroom Bomb™ Grow Bag is professionally vacuum-sealed before shipping. This helps:

• Lock in freshness

• Protect the bag during transit

• Reduce exposure before injection

• Ensure you receive a clean, ready-to-use product

Sterilized & Made Fresh to Order

• Sterilized using commercial-grade autoclaves

• Designed to eliminate contamination without damaging nutrients

• Made fresh and shipped within 3 business days

• Stored and prepared in controlled conditions

Each bag also includes a 0.2-micron filter patch, allowing proper gas exchange while preventing contaminants from entering the bag.

What You’ll Need

• One spore syringe (sold separately)

• A clean injection process (simple instructions included)

That’s it.

No pressure cookers, no tubs, no complicated setups.
