Everything you need to grow smarter

Built around how microgreens are actually grown — not a generic to-do app with plants painted on it.

Today's Tasks, Not a List
The home screen is a checklist built fresh each morning: what to pre-soak, plant, water, move to light, and cut. Overdue work is flagged first. Tap a tray to act on it without leaving the screen.
Every Stage, Properly
Pre-soak, planted, weighted, germinating, blackout, in light, ready, harvested — with per-crop timing. Start a tray at whichever stage your process actually starts, and skip the ones you don’t use.
Push Reminders — Free
Watering nudges on your phone at a morning and evening time you choose, in your timezone. One notification per slot, however many trays are due. Included on every plan, including free.
80 Crops, 284 Varieties
Sow weights, days to harvest, germination and blackout timing, pre-soak hours, and expected yields ship built in — and every one of them is yours to override for your own conditions.
Plan Backward From Harvest
Name the day you need it cut and the app back-calculates the sow date from that crop’s timing. Stop doing delivery-date math in your head.
Succession Planting
Set a wave count and an interval — every 7 days for 4 weeks — and schedule the whole run in one action. Printed labels sort by sow date with a "Wave N of M" separator.
Harvest & Yield History
Log weight and a quality grade with the yield ratio computing live as you weigh. Multiple harvests per tray, expected-vs-actual day tracking, and a permanent record of what each tray really produced.
True Cost Per Tray
Seed, medium, fertilizer, and electricity — including light wattage and runtime allocated across your running trays, fertilizer priced from your dilution rate and the water each tray drank, and reusable mats amortized over every grow they serve. Paid plans.
Supplies & Seed-Lot Traceability
Seeds, mediums, fertilizers, and equipment tracked per purchase batch, with auto-deduction on planting and low-stock alerts. Any tray traces back to the exact lot that grew it.
Orders That Plant Themselves
Customers, orders in pounds and ounces, and recurring standing orders. Each order becomes a planting plan where staggered crops converge on one cut date — then one button plants the batch.
Barcode Labels & Scanning
Print labels for trays and supply batches, then scan to act — jump straight to a tray, or scan a whole shelf into a selection and water it in one tap. Phone camera or handheld scanner.
Calendar, Stats & Export
A month grid of every sow, transition, and harvest. A Grow Stats page with yields per crop, weekly averages, and failure patterns. CSV and Excel export on paid plans — your data stays yours.

How it works

Plant a tray

Pick a crop and variety, or reuse a saved setup. Sow weight is calculated for your tray size, and you can schedule by sow date or by the date you need it harvested.

Follow the daily list

Open the app — or get a push reminder — and see exactly what needs water, what should move to light, and what is ready to cut. Tap to log it and it disappears.

Harvest and improve

Weigh the cut, grade it, and the tray closes out with a permanent cost record. Grow Stats then shows you which crops are worth your shelf space.

Your first tray is a minute away.

Create an account and add a tray—no payment info needed.

Simple pricing, priced on trays

Every plan gets the whole app. The only things paid plans add are cost analytics and CSV/Excel export — after that you’re just buying tray capacity.
