Inside the Grow Bag
CVG Substrate
Balanced mix of coco coir, vermiculite, and gypsum designed to support strong mycelium growth and high-yield flushes.
Organic Milo Grain
Fully sterilized milo grain for fast colonization and reliable results across a wide variety of mushroom strains.
Polypropylene Bag
Durable and heat-resistant to withstand sterilization, shaking, and fruiting without tearing.
0.2 Micron Filter Patch
Allows gas exchange while keeping contaminants out.
Injection Port
Inject spores easily while keeping the bag sealed and sterile.
How it Works
STEP 1
Use a spore syringe or liquid culture to inoculate the grain through the self-healing injection port. Once injected, let the mycelium begin to grow.
STEP 2
When about 25% of the grain is colonized with white mycelium, break it up and mix it evenly with the substrate to help it spread faster.
STEP 3
After full colonization, cut open the top of the bag to expose it to fresh air and light. This triggers pinning and starts the fruiting process.
Watch Them Grow!
Mushrooms will begin to sprout within 7 to 14 days. Maintain moisture and airflow, then harvest when mature.
Customer Reviews
This has been so far the BEST substrate I've used for growing. My mycelium exploded in this mix and this will be my go to substrate from now on.
