Kit: Sterile substrate for sclerotia (millet), liquid mycelium

Sterile millet-based sclerotia substrate with liquid mycelium is a ready-to-use kit designed for maximum convenience when growing mushrooms at home or professionally. It contains all the necessary components to ensure fast, uniform, and safe mycelial colonization without the need for additional substrate sterilization. This product is ideal for cultivators of all skill levels—from beginners to experienced growers—who value quality and reliability in their sclerotia cultivation.

Included in the kit

• A 10ml liquid mycelium selected from a special range of proven scleroforming species that provide high activity and viability.
• A 1.4 litre grain substrate based on millet, which has undergone a double autoclave sterilization process to ensure complete purity and eliminate the risk of contamination by unwanted microorganisms.
• An optimally selected mixture of coconut fiber, peat and gypsum to maintain the structure of the substrate, provide the necessary moisture and pH balance, which promotes the development of mycelium and the formation of dense sclerotia.
• A package of two polypropylene bags equipped with a micropore vapor-permeable filter and a rubber inoculation port, allowing for easy and safe introduction of mycelium, maintaining the sterility of the medium until use.

Benefits of using millet-based substrate

Millet is considered one of the best substrates for cultivating sclerotia due to its fine grain structure, which creates a large contact surface for the mycelium. This promotes rapid spread and dense growth of the mycelium, resulting in the formation of large, healthy sclerotia. The coconut fiber included in the substrate increases its breathability and moisture retention, while gypsum maintains a stable pH level, essential for optimal mushroom growth.

Substrate characteristics

• Double autoclave sterilization ensures maximum substrate purity, eliminating the risk of contamination and increasing the chances of successful cultivation.
• Vacuum polypropylene packaging with heat resistance up to 126°C maintains the sterility of the substrate until it is opened, which guarantees the quality and safety of the product.
• The rubber inoculation port allows for easy and safe addition of liquid mycelium without breaking the seal, reducing the risk of contamination and simplifying the inoculation process.
• The elasticity of the bag promotes uniform distribution of the mycelium throughout the entire volume of the substrate, which ensures uniform development of the mycelium and a high-quality harvest.

How to use correctly

To begin, select a suitable mycelium strain based on your personal preferences and the type of mushroom you plan to grow. Using the rubber port, inoculate the liquid mycelium into the grain substrate, shaking the bag thoroughly to distribute it evenly. After inoculation, place the bag in a warm, dark, and ventilated area with an optimal mycelial growth temperature (usually 22–26°C). For casing, you can divide the substrate into two 1-liter blocks using sterile casing soil to stimulate sclerotia formation.

Advantages of the cultivator kit

• The lack of need to sterilize the substrate yourself saves time and resources, and is especially useful for beginners and those without specialized equipment.
• Guaranteed sterility and hermetic packaging ensures a high level of safety and minimizes the risk of mycelial infection.
• The simplified growing process makes this kit accessible even to users without mushroom growing experience.
• Reducing the likelihood of errors in substrate preparation increases the chances of a successful and high-quality harvest.

Important recommendations

Store the substrate in the refrigerator until ready to use, without opening the package ahead of time, to maintain sterility. Liquid mycelium has a limited shelf life, so it is generally used immediately after receipt.

Using a sterile substrate significantly reduces the risk of contamination and infection, but maintaining good hygiene remains essential for a safe process.
