Mushroom Substrate

Substrate is the growing substance you use to grow mushrooms

Our substrate is about 80% hardwood and 20% straw. Sometimes we mix in various other stuff, like grains, to improve the output of our mushroom growing blocks.

There’s an intriguing allure to the world of mushroom cultivation – the idea of growing a unique and exotic delicacy from scratch. But, as with any form of gardening or farming, knowledge of the right materials is crucial. And when it comes to cultivating mushrooms, the substrate you use can make all the difference.

At its core, mushroom substrate is essentially the food source for your mycelium, the thread-like network of cells that will eventually give rise to mushrooms. It is a nutrient-rich mixture that is designed to provide everything needed for fungi to thrive. And while the exact composition of the substrate can vary, there are a few key elements that are commonly used.

For example, hardwood is often used as a base for mushroom substrate due to its high lignin content. Lignin is a complex polymer that provides structural support for many plants, but it can be difficult for fungi to break down. This makes it an ideal food source for mushrooms, as they are some of the only organisms capable of breaking down lignin. Additionally, straw is frequently added to the mix due to its high nutrient content, as well as its ability to hold moisture.

But the art of mushroom cultivation isn’t just about putting any old combination of materials together. The specifics of your substrate mix can have a huge impact on the final product. For example, some growers swear by adding specific types of grains (like rye or wheat) to their substrate, as this can help promote more vigorous mycelial growth. Others may add supplements like soybean meal or gypsum to provide additional nutrients or modify the pH of the substrate.

Ultimately, the key to crafting the perfect mushroom substrate is to experiment and find what works for you. Whether you’re a seasoned grower or a complete beginner, there’s always more to learn about the fascinating world of fungi. But with a little creativity and a solid understanding of the basics, you too can cultivate a delicious and unique crop of mushrooms to enjoy.
