Mycro tracks every batch from spawn to final flush — so you catch contamination early, stop guessing your yields, and finally know your real cost and profit per block.
No login, no install — your batches save right in your browser. Oyster, lion's mane, shiitake, king trumpet & more. Built for legal culinary & medicinal growers.
Field-crop software models beds and rows. Mushroom farming is indoor, biological, batch-based manufacturing — and the things that decide whether you make money are different.
Track each batch through inoculate → colonize → fruit → harvest. See exactly where everything stands today.
Log contamination by step, strain, and substrate. Spot the pattern that's quietly eating 15% of your blocks — and fix the root cause.
Real BE per strain and substrate, flush by flush. Know which projects actually pay and which just look busy.
True cost per block and per pound — substrate, spawn, bags, labor, energy. Quote restaurants with confidence, not vibes.
Colonization and fruiting timelines turn into a schedule, so you know what's coming ready and never miss a flush.
Standing restaurant & market orders, pack lists, and simple invoices — match production to demand.
Genuinely useful, no email required — a taste of how Mycro thinks about your grow. Use them, share them, bookmark them.
The actual batch tracker — not just a calculator. Add a batch, advance it through each stage, and get biological efficiency, days-in-stage and your contamination rate automatically. Comes preloaded with sample batches; saves on your device.
Substrate hydration, spawn ratio, expected yield, and full cost-and-profit per block — the math you currently do by hand.
Scale a Masters Mix or supplemented-sawdust recipe to any batch: exact sawdust, soy hull, bran, gypsum & water to field capacity.
Temperature, humidity, CO₂, fresh air & light for 14 gourmet & medicinal species — searchable, filterable, °C/°F.

Mycro is grow-operations software for small gourmet and functional mushroom farms — the growers selling oyster, lion's mane and shiitake to restaurants, markets and CSAs. It runs in any web browser with nothing to install, and includes a free Grow Log plus calculators for substrate, spawn ratio, yield and cost.
Yes. Mycro's Grow Log is free with no sign-up — open usemycro.com/grow-log.html and start logging batches in your browser. It tracks each batch from inoculation through colonization, fruiting and harvest, and automatically computes biological efficiency, days-in-stage, an overdue-colonization flag and your contamination rate. It exports to CSV and JSON.
The free tools and Grow Log cost $0 with no account. The cloud Grower plan is an early-access target of about $12/month (unlimited batches, analytics, reports); the Farm plan about $24/month adds wholesale orders, labels and multi-user. A one-time $99 Founding Grower pre-order locks founder pricing for life and is refundable before launch.
MycoFile and MycoHub are native mobile apps you install. Mycro runs in any web browser with nothing to download, its Grow Log is free with no account or item cap, and its grow-math engine is open source. Mycro is built specifically for the commercial gourmet and functional farm rather than the hobby grower.
No. Mycro is web-based — it opens in any browser on a phone, tablet or computer, with nothing to download or update. The free Grow Log even works without an account, saving your batches in the browser. The paid cloud plans add sync, backup and multi-device access across your whole team.
Biological efficiency (BE) is fresh harvest weight as a percentage of dry substrate weight — the core yield metric for mushroom farms. Mycro calculates BE automatically for every batch in the Grow Log and Grow Calculator, so you can compare strains and substrates. A typical oyster batch runs roughly 75–100% BE.
Mycro is for small commercial gourmet and functional mushroom farms — operations selling oyster, lion's mane, shiitake and similar culinary or medicinal mushrooms weekly to restaurants, farmers' markets and CSAs. It's built for the serious hobbyist going pro and the established small farm, not for psilocybin or large industrial operations.
