Bulk Substrate Coco Fire Mix
🌱 Premium Sterilized Mushroom Grow Blocks (8–9 lb Each)
Our Bestselling Substrate Blocks — Trusted by Growers Nationwide
Whether you’re running a full grow room or starting your mushroom journey, these blocks are designed for high yields, strong resistance, and beautiful flushes.
🧪 What Makes It Special:
We craft each block using our proprietary blend of coco coir, sawdust, soybean hulls, nutrients — and a little love. Every block is:
- 8–9 lbs of fully sterilized substrate
- Sealed and steam sterilized under high pressure
- Equipped with a high-quality filter patch for airflow and contamination resistance
🍄 How to Use:
Simply inoculate with your own grain spawn or liquid culture, and place in your preferred fruiting environment (humidity tent, monotub, or grow room).
With proper conditions, each block can yield 3+ lbs of mushrooms across multiple flushes.
