What is a mushroom substrate?

A mushroom substrate can be nourishing or non-nourishing and is used to grow mushrooms, providing the essential foundation that different mushroom species need to thrive. Whether you’re growing mushrooms at home or on a larger scale, choosing the right substrate is crucial for successful mushroom cultivation. The substrate acts as a growth medium for the mycelium, the vegetative part of the fungus, which spreads throughout the substrate and prepares it for fruiting. Common materials used as substrates include coco coir, vermiculite, and manure, especially for dung-loving mushrooms.

Before you start growing, understanding the substrate’s role can make all the difference in your results. Properly prepared substrates ensure that your chosen mushroom species get an optimal environment for growth. At The Hemp Haus, we are dedicated to helping you with all your mushroom-growing needs, offering tips and insights to make your mushroom-growing journey a success. With the right knowledge and substrate, you’ll see your mushrooms flourish and enjoy the rewarding process of home-grown mushrooms. Don’t underestimate the importance of a well-prepared, nutrient-rich substrate!

What is the most commonly used substrate for mushroom production?

When it comes to optimizing the growth of dung-loving mushrooms, selecting the right mushroom substrate is essential. The most commonly used substrates for CVG include coco coir, vermiculite, and gypsum. Many mushroom growers also utilize coco coir (coconut fiber) due to its excellent water retention properties and sustainability. Pre-made substrate kits are available for those looking for a convenient starting point. Using a grain or sawdust base within these kits ensures proper mushroom growth. Whether you’re filling a bin, a bag, or utilizing kits, understanding these substrate options can make all the difference in your mushroom production success.

Mushroom growing tips

At The Hemp Haus, we understand the thrill of watching your favorite fungi grow! For those just starting their mushroom-growing journey, here are some invaluable tips. Ensure your substrate is well-prepared by using a high-quality grow kit that includes pre-made spawn. This can make the initial setup smoother and quicker. Remember to carefully monitor the water content in your substrate; it’s essential for the mycelium to thrive.

If you are using mono tubs without a flow hood, we strongly suggest going with the CVG substrate versus an amended CVG with manure due to contamination issues. Proper substrate preparation and careful monitoring are key to a successful mushroom harvest.

How to pasteurise mushroom substrate

To successfully grow dung-loving mushrooms, it’s crucial to master the art of pasteurizing your mushroom substrate. Pasteurizing helps eliminate unwanted microbes without compromising the nutrients essential for mushroom growth. Here’s a simple method to get you started. First, prepare your chosen substrate mix and bring a large pot of water to a temperature of around 160°F (71°C). Submerge the substrate in the hot water and maintain this temperature for at least an hour, ensuring complete coverage. Afterward, drain and allow it to cool. If you’re using a substrate kit, follow the instructions carefully. Proper pasteurization not only balances the microbial environment but also boosts the efficiency of your growing process. Remember, unlike sterilization, pasteurization doesn’t completely eradicate all organisms, but creates a favorable environment for mushrooms to thrive. Once the substrate is pasteurized, you’re ready to mix in your colonized spawn and begin growing your mushrooms. Enjoy the journey and happy mushroom growing with The Hemp Haus & Mane Street Mushrooms!


How to sterilize a mushroom substrate

Ensuring your mushroom substrate is properly sterilized is essential for successful cultivation. First, prepare your substrate mix, which might include coco coir, vermiculite, gypsum, a bit of dung, and water. To sterilize your mushroom substrate, use a pressure cooker or autoclave. This process eliminates any unwanted bacteria or fungi that might outcompete your mushrooms. After sterilizing, let the substrate cool completely before introducing your colonized mushroom spawn.

Remember, the quality of your sterilized substrate directly impacts the health and productivity of your mushroom crop. Sterilizing techniques such as pressure cooking or steaming ensure a clean environment for your mushrooms to thrive. By maintaining a contamination-free substrate through thorough sterilization, you’re setting up your mushrooms for optimal growth. Sterilize your substrate with care, and you’ll reap the delicious benefits!


How long to pressurize mushroom substrate?

If you’re wondering how long to pressurize your mushroom substrate, it’s essential first to recognize the type of substrate you’re using. For most mushroom substrates, including those favored by dung-loving mushrooms, the rule of thumb is to pressurize your substrate at 15 PSI for about 90 minutes minimum. This ensures that you effectively sterilize the substrate, eliminating any unwanted contaminants. Consistency is key, as improper pressurization can affect your mushroom yield. Good pressurization practices are crucial for a successful mushroom growing experience.

It’s worth noting that different methods exist for treating substrates, and the pressure duration might vary slightly depending on the substrate’s density. However, maintaining a regular schedule and technique will contribute to better results. Always remember, to preserve your hard work, pressurize and sterilize thoroughly. Check our guides for more detailed insights and other treatments. Our years of expertise and dedication help us stand out in the world of fungi cultivation.

How to inoculate mushroom substrates

Inoculating your mushroom substrate is a crucial step to ensure a fruitful harvest. To start, you’ll need to mix your chosen substrate, whether it be CVG or a manure  amended one , with your colonized  mushroom spawn. First, ensure your substrate is properly pasteurized or sterilized to prevent contamination. Once prepared, evenly distribute the mushroom spawn throughout the substrate, making sure it’s thoroughly mixed in. The spawn will introduce mycelium, which will colonize the substrate, forming the foundation for your mushrooms to grow. Keep the inoculated substrate in a warm, humid environment to encourage mycelium growth. This can be done by placing the substrate in a specialized growing bag or container. Regularly monitor the substrate to check for signs of colonization. Within a week, you’ll start noticing mycelium spreading throughout the substrate. We recommend using high-quality grain spawn and  for dung-loving mushrooms. If you’re ready to begin, you can order your supplies and get started on your mushroom-growing journey!
