CVG Sterile Mushroom Substrate FAQs
What is CVG Substrate?
CVG is a type of inexpensive mushroom substrate, meant to provide the necessary nutrients to mushroom spores and facilitate mycelium growth. The name stands for Coco coir, Vermiculite, and Gypsum, the three main components. It can be used to grow magic mushrooms, but there are plenty of dung-loving mushrooms that thrive in this substrate.
What is the ideal mushroom substrate for my culture?
Most mushrooms require their own specific combination of nutrients. This means that different mushroom varieties like oyster mushrooms and Lion's mane mushrooms might require different types of substrates. You'll need to research the most effective mushroom substrate for your mushroom of choice.
Some of the most popular choices for substrate material are manure, straw, hardwood sawdust, coffee grounds, logs, and cardboard.
How do I know if my mushroom substrate is bad?
One of the biggest dangers of indoor mushroom growing is the risk of contaminating your substrate and your culture. Here are a few signs to look out for:
- Strong, bad smell
- Abnormal growths (misshapen or stunted mushrooms)
- White or blue-green mold growing on the surface
