How to mix spawn with bulk substrate (spawning to bulk) - Spawning to bulk (S2B) is the process of mixing your fully colonized grain spawn with a larger volume of “bulk substrate” (like coco coir). This provides the moisture and surface area needed for the mushrooms to fruit. 1. The Ingredients 2. The Step-by-Step Process Step 1: Sanitize Everything Even though colonized grain is more resistant to […]
How to make liquid culture - Making your own liquid culture (LC) is a game-changer for scaling up. It allows you to turn a tiny bit of mycelium into an almost infinite supply of “liquid gold.” The key is creating a nutrient-rich broth that is weak enough to prevent caramelization during sterilization but strong enough to fuel rapid growth. 1. The […]
Why not make liquid culture from spores or spore syringe - While it is technically possible to inject a spore syringe into a liquid culture (LC) jar, it is widely considered a high-risk gamble that most experienced growers avoid. The primary reason is that spores are inherently dirty, and liquid culture is the perfect environment for “silent” contamination. 1. Spores Are Not Sterile Mushrooms grow in the wild (or […]
Why a laminar flow hood is a necessity - While many growers start with a Still Air Box (SAB), transitioning to a Laminar Flow Hood is often considered the “graduation” into serious mycology. It isn’t just a luxury; for certain advanced techniques, it becomes a mechanical necessity. Here is why a flow hood is the backbone of a professional-grade mushroom lab: 1. The Physics of “Laminar” Flow The […]
Why use 70% alcohol for sterilization? - In mushroom cultivation, it might seem logical to assume that higher concentrations of alcohol (like 91% or 99%) would be more effective at killing contaminants. However, 70% Isopropyl Alcohol (IPA) is the industry standard for several specific biological reasons: 1. Slowing Down Evaporation 2. Penetrating the Cell Wall 3. Cost and Safety Best Practices for Mushroom Sterilization […]
