CVA Blend Substrate (Coco Coir, Vermiculite, Azomite)

Pre-mixed for optimal hydration, aeration, and mineral content to promote strong mycelium growth.

Pasteurized to reduce contaminants while preserving beneficial microbes.

Designed for use with colonized grain spawn for easy bulk substrate preparation.

Prepare Colonized Grain Spawn – Ensure your grain spawn is fully colonized (white and covered with mycelium). You’ll need 2-3 lbs of colonized grain per 5 lb substrate bag.

Mix with Substrate – Sanitize your hands and workspace with 70% isopropyl alcohol, cut open the substrate bag and break it up gently, and pour the colonized grain into the bag and mix thoroughly.

Seal & Incubate – Fold or clip the bag closed, allowing for some airflow, store in a warm, dark place (65-75°F) for 10-14 days until fully colonized.

Initiate Fruiting – Once fully colonized, cut small holes in the bag or transfer to a fruiting chamber. Maintain 80-90% humidity, indirect light, and airflow.

Harvest & Enjoy – Mushrooms will begin forming within 5-10 days. Harvest when caps fully develop, and continue misting for multiple flushes!

✅ Optimized for Mycelial Growth – Provides the ideal moisture and structure for fast, even colonization.

✅ High-Yield & Easy to Use – Pre-hydrated and pasteurized for a hassle-free experience.
