Grow Bag Guide – Find the Perfect Bag for Your Research

1. BRF Bags (Brown Rice Flour – All-in-One Bags)

The simplest option – just inject, mix, and let it grow!

How the BRF All-in-One Bag Works

• Inject the spores into the bag.
• Mix the bag straight after injecting.
• The bag will colonize (fill with mycelium).
• Mix it again at about 30% and about 60% colonized to spread growth evenly.
• Let it fully colonize, then it will fruit inside the bag!

BRF Bag Sizes & Estimated Yields

• 1LB BRF Bag → ~150g wet weight
• 2LB BRF Bag → ~350g wet weight
• 4LB BRF Bag → ~750g wet weight

2. Dung Master Bags (Horse Manure-Based All-in-One Bags)

For dung-loving species – easy and potent!

How the Dung Master Bag Works

• Inject spores into the bag.
• Allow the bag to begin colonizing.
• Once around 30% colonized, mix the bag gently to spread growth evenly..
• Mix again at roughly 60% to ensure full and even colonization.
• Once fully colonized, introduce a gentle 12-hour light and 12-hour darkness cycle to trigger fruiting and pinning inside the bag.

Dung Master Bag Sizes & Estimated Yields

• 1LB Dung Bag → ~145g wet weight
• 2LB Dung Bag → ~350g wet weight
• 4LB Dung Bag → ~770g wet weight

3. Grain Bags (For Use in Monotubs)

For bulk growing – needs a fruiting chamber.

How Grain Bags Work With a Monotub

• Inject spores into the bag.
• Once fully colonized, mix it with CVG (Coco Coir, Vermiculite, and Gypsum).
• Move to a fruiting chamber (monotub) – mushrooms will not fruit in the bag.

Grain Bag Sizes

• 1LB Grain Bag
• 1.5KG Grain Bag
