## What is Mushroom Grow Log?

Myco is the mushroom cultivator's journal - log every grow from inoculation through harvest with substrate recipe, spawn ratio, colonization progress photos, fruiting conditions, and flush-by-flush yield data. The contamination identification guide helps you catch trich, cobweb, and bacterial issues early - when the tub can still be saved. Species guides cover oyster, lion's mane, shiitake, king trumpet, reishi, and more with specific substrate, temperature, and humidity requirements. Yield analytics across grows reveal which techniques produce YOUR best results. Whether you're opening your first grow kit or running 10 tubs simultaneously, Myco turns intuition into data and every grow into a lesson.

GROW LOG
Track everything from inoculation to retirement: species and strain, spawn source and ratio, substrate recipe and pasteurization method, container type, and inoculation notes. Log daily progress with colonization percentage, temperature, humidity, FAE schedule, and observations. Add photos at every stage to document the mycelium spreading, pin formation, and fruit development.

FLUSH-BY-FLUSH YIELD TRACKING
Record every harvest: fresh weight, dry weight, quality, and notes. Calculate biological efficiency. Know when a tub has another flush in it - and when to retire it and start fresh.

CONTAMINATION GUIDE
The reference you need in one tap. Trichoderma (green mold - game over), cobweb mold (wispy grey - treatable with H2O2), bacterial blotch (slimy wet substrate), lipstick mold (orange - spawn issue), black mold (health hazard), and bruising (blue - totally harmless). Appearance, smell, timing, severity, and recommended action for each.

SPECIES LIBRARY
Blue Oyster, Pink Oyster, Lion's Mane, Shiitake, King Trumpet, Reishi, and Wine Cap - with substrate requirements, colonization temperature, fruiting temperature, humidity targets, and yield potential for each species.

SUBSTRATE REFERENCE
CVG recipe (coco coir, vermiculite, gypsum) with full bucket tek protocol. Masters Mix for supplemented species requiring sterilization. Still Air Box setup guide.
