Allocate mixed crop batches across trays

Count the required cells, label crops and keep the last tray’s spare capacity visible.

Open Seedling Batch Calculator →

Add crops separately

Each crop has its own target, germination estimate, usable-seedling estimate and seeds per cell. The calculator rounds each crop to whole cells before adding the batch. It then divides the total by your tray capacity and rounds up to complete trays. This makes spare capacity visible rather than hiding it in a fractional-tray result.

Use the map as a counting aid

The colored allocation follows the crop order. The map uses a compact display grid; it is not the physical row/column specification of a particular tray. Choose a tray number to see the cells assigned to that tray. If crops require different watering, temperature or timing, separate them into compatible physical batches even when a combined numerical plan fits.

Label before sowing

Download the batch plan and crop label rows, then add variety and sowing date by hand. If you want to fill the entire final tray with media, enable that option; the reserved mix then includes its spare cells. Saved settings retain your batch assumptions for the next sowing. Revisit germination and usable-seedling estimates when a later seed lot or growing setup behaves differently.
