From Substrate to Sterile: Everything You Need to Grow Gourmet Mushrooms

Welcome to the Growing Supplies collection at Kai Kai Farm — your one-stop destination for high-quality mushroom cultivation products and equipment. Whether you're a beginner exploring low-tech methods or a seasoned mycologist scaling your gourmet grow operation, this collection is designed to support every stage of the mushroom growing journey. Our mission is to make mushroom cultivation more accessible, sustainable, and rewarding by offering carefully selected, chemical-free supplies you can trust.

Substrate Ingredients That Support Strong Yields

A nutritious, well-prepared substrate is the foundation of successful mushroom cultivation. At Kai Kai Farm, we offer a variety of bulk substrate ingredients and ready-to-use blends suitable for gourmet mushrooms including oyster, lion's mane, shiitake, pioppino, chestnut, and more.

• Hardwood Sawdust: Sourced from Australian-grown timber, our hardwood sawdust provides an ideal lignin-rich base for many wood-loving mushroom species. It can be used alone or mixed with supplements like soy hull beans or wheat bran for improved yields.

• Soy Hull Pellets: This nitrogen-rich supplement is perfect for creating Master's Mix when blended with hardwood sawdust.  100% Australian grown and processed and non GMO.

• Organic Wheat Bran: This nitrogen-rich supplement is perfect for boosting the nutritional profile of your base substrate. It enhances colonisation speed and fruiting density, especially in sawdust or straw-based recipes.

• Rice Bran Pellets: An excellent, shelf-stable source of nutrients, rice bran pellets are easy to measure and mix into your substrate. Use in boiling water pasteurisation or steam sterilisation.

• Gypsum & Lime: Add hydrated lime or gypsum to balance pH, reduce contamination, and improve structure and aeration in your substrate. Especially helpful when working with straw, coir, or recycled materials.

All substrate components are food-grade or agricultural-grade and stored with care to ensure quality and safety.

Eco-Friendly Pasteurisation & Additives

For growers looking to avoid chemical treatments or expensive sterilisation equipment, we offer products that support low-tech, sustainable pasteurisation methods.

• Pine Pellets (Australian-Grown): A clean, chemical-free option for creating pasteurised substrate through boiling or bucket-tek methods. These pellets break down into a fluffy, hydrated medium ideal for oyster mushrooms.

These options are ideal for small farms and home growers who want to maintain a natural, eco-conscious cultivation practice.

Tools for Clean and Sterile Technique

Keeping your grow environment sterile is critical to reducing contamination and increasing your success rates. That’s why our collection includes tools and supplies designed specifically for clean handling in spawn prep, inoculation, and fruiting.

• Isopropyl Alcohol (70% 100mL Spray Bottles): Quick-drying and effective against bacteria and fungi, our IPA is perfect for sanitising hands, tools, and surfaces in your workspace.

• Micropore Tape: Allows air exchange while preventing contamination. Ideal for sealing gas exchange holes on spawn bags, jars, or containers.

• Lab Sterile Kits: These include gloves, face masks, hair nets, gowns, and IPA wipes—everything you need to create a sterile working environment, whether in a home lab or a small grow room.

These items are trusted by growers for their reliability and ease of use during critical stages of inoculation and handling.

Clean Growing for Everyone

We believe that growing gourmet mushrooms should be clean, chemical-free, and accessible to all. That’s why every product in our Growing Supplies collection is selected with care and tested in real-world growing conditions. Whether you're following a sterile lab-style protocol or a simple home bucket method, we have solutions that fit your needs.
