5lb Bag – Pasteurized Substrate at Field Capacity

About Our Substrates

CVA | Contamination-Resistance for Hobbyists
Our CVA blend combines coconut coir, vermiculite, and Azomite (a volcanic mineral powder with 70+ trace minerals). It offers a forgiving, low-nutrient option that resists contamination—ideal for beginner-friendly gourmet mushrooms such as oyster and pioppino.

Alien Dirt™ | Substrate from Outer Space
Alien Dirt™ is Mycelio’s premium manure-based substrate, engineered for speed and nutrition. Perfect for compost-loving species like portobellos and wine caps, it delivers vigorous colonization and heavy flushes.

Master’s Mix | The Woodlover’s Choice
A hardwood sawdust and soy hull blend, Master’s Mix is the go-to substrate for functional and gourmet wood-loving species such as lion’s mane and reishi. High in nutrition, it supports higher yields and denser fruits.
