MycoMix: Substrate Calculator

Prepare perfect mushroom substrates with mathematical precision. MycoMix is the ultimate offline utility for hobbyist mycologists and micro-producers cultivating edible and medicinal species.

Achieving exact moisture content—or "field capacity"—is the single most critical factor in indoor mushroom cultivation. Substrates that are too dry stall growth; substrates that are too wet create anaerobic pockets that invite mold and bacterial sour rot. MycoMix eliminates the guesswork, helping you calculate exactly how much water and material you need.

Designed for latex-glove operations, MycoMix features a dark, high-contrast interface with tactile haptic feedback for quick adjustments in the lab or grow space.

KEY FEATURES

• Hydration & Moisture Calculator
Select classic recipes (CVG, Master's Mix, hardwood sawdust, coco coir) or configure custom ratios. Slide to adjust target moisture (60%–72%) and instantly see how much dry substrate material and water you need.

• Monotub Geometry Planner
Enter length, width, and desired substrate depth. MycoMix calculates total substrate volume in Liters/Quarts, then estimates the required wet substrate and grain spawn weights.

• Unicorn Filter Bag Calculator
Calculate batch requirements for standard filter bags (Unicorn XLS-A, 14-A, 10-T). Input your desired bag quantity to prepare bulk materials easily.

• Spawn Weight Start Mode
Have a specific amount of grain spawn ready? Input your spawn weight and ratio (e.g., 1:2) to instantly discover the exact wet substrate and water required.

• Lab Media & Liquid Culture (LC) Calculator
Scale standard laboratory recipes (Malt Extract Agar - MEA, Potato Dextrose Agar - PDA, Malt Yeast Extract Agar - MYYA, Liquid Culture, and Water Agar) to your target volume (ml or fl oz). Instantly scale agar, dextrose, LME, and yeast extract to achieve perfect concentration.

• Integrated Autoclave & Sterilization Timers
Keep track of sterilization times directly in the lab with built-in autoclave timers, including active timer notifications that run in the background.

• Custom Recipe & Ingredients Builder
Expand your library. Define custom dry densities and moisture absorption coefficients for specialized agricultural inputs like soy hulls, oat bran, and peat moss.

• Safe Supplementation Warnings
Get live visual alerts if nitrogen-rich supplements (like wheat bran) exce
