CVG Substrate

Expertly Formulated for Dung-Loving Mushrooms
Our precisely balanced substrate fuels robust mycelial growth, making mushroom cultivation simpler than ever. Available in 4, 6, or 10 lb options, we’ve got the right size for your needs.

Enhanced CVG Components for Optimal Results
This blend of coco coir, vermiculite, and gypsum improves moisture retention, aeration, and mineral availability, ensuring healthier, more abundant flushes and boosting your overall harvest success.

Convenience of Sterilization
Arriving pre-sterilized, our bags offer a contamination-free environment, so all you need to do is inoculate and watch your mushrooms grow. No complex sterilization required—just simple, confident cultivation.

Perfect for Large-Scale Cultivation
Designed for efficiency, the substrate's consistent nutrient balance and moisture retention make it ideal for scaling up production, ensuring uniform growth and maximizing output across large batches.

Bigger Bags, Bigger Harvests
Our larger bags offer more surface area and nutrients, paving the way for higher yields and multiple flushes. Maximize your harvest potential with our nutrient-packed substrate that keeps mushrooms growing longer.

To ensure the substrate remains uncontaminated, use clean, sterile tools and environments during handling. 

Follow detailed cultivation instructions specific to the mushroom species you are growing for optimal results.

Q: How long does it take for mushrooms to colonize this substrate?

A: Colonization time can vary by mushroom species and growing conditions, but with our substrate’s balanced blend and moisture retention, you can typically expect full colonization in 2-4 weeks.

Q: What should I do to maintain the substrate's sterility?

A: Always handle the substrate with clean equipment and in a clean space. If inoculated with liquid culture, ensure your workspace is as sterile as possible to prevent contamination.

Q: How much grain spawn should I use to mix with my substrate bag?

A: As a general guideline, we recommend a 1:2 ratio of fully colonized grain spawn to substrate for dung-loving mushrooms. For example, if you use 6 lbs of substrate, you should ideally mix in 3 lbs of grain spawn to achieve optimal results.
