5 Ib Sterilized Masters Mix 3T Unicorn Bag

Rhizo Funga’s 5 lb Master’s Mix is a small-batch, sterilized bulk substrate formulated for fast colonization and reliable yields. Each bag contains a 50/50 blend of hardwood sawdust and soy hulls, hydrated to perfect field capacity and sterilized for optimal performance.

Every unit is sealed in a genuine Unicorn 3T bag, featuring a 0.2-micron filter patch that balances gas exchange while preventing contamination. The 3T size is ideal for individual fruiting blocks or small-batch spawn expansion in monotubs, tents, and other controlled environments.

Designed for Consistency

Master’s Mix is the industry standard for gourmet mushroom cultivation because of its superior nutrition, water retention, and structure. It supports rapid mycelial growth, dense fruiting bodies, and multiple flushes when properly maintained.

Moisture Content: Hydrated precisely to field capacity for even colonization and strong yields.

How to Use

Break up your colonized grain spawn and mix evenly with the substrate in a clean environment (such as a still air box or flow hood).

Recommended ratio:

• 1 lb of colonized grain spawn for every 5 lbs of Master’s Mix.

Best Practices

• Allow one week after arrival before inoculation to ensure sterility was maintained in shipping.

• Avoid open flame near alcohol.

Storage
