Frequently Asked Questions
A substrate mixture is the growing medium used for mushroom cultivation. It typically contains a combination of materials that provide nutrition and structure for mushroom mycelium to colonize and eventually fruit.
The ratio of different ingredients in your substrate affects moisture retention, nutrition availability, pH levels, and overall structure. Different mushroom species thrive in different substrate compositions, and our visualizer helps you understand these relationships.
CVG stands for Coco coir, Vermiculite, and Gypsum - a popular substrate mix for many mushroom species. The standard ratio is typically 5 parts coco coir to 2 parts vermiculite with a small amount of gypsum, but our visualizer allows you to experiment with different proportions.
Adjust the sliders to change the ratio of different substrate ingredients. The 3D visualization will update in real-time, showing you the composition. The tool also provides supplemental information about the properties of your custom mix, such as moisture retention and nutrient content.
