What to enter
| Input | Meaning and units |
|---|---|
| Tray count (trays) | Enter tray count in trays; use the same basis as the other measurements. |
| Occupied cells per tray (cells/tray) | Enter occupied cells per tray in cells/tray; use the same basis as the other measurements. |
| Measured volume per cell (mL/cell) | Enter measured volume per cell in mL/cell; use the same basis as the other measurements. |
| Extra volume allowance (%) | Enter percentage units: 5 means 5%, not a fraction of 0.05. |
Understanding your result
Cell volume is measured or supplied; compaction, settlement and losses are not predicted.
Common mistakes
- Use occupied cells per tray rather than tray count again.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.

How much measured cell volume do my plug trays hold?
Estimate total growing-media liters from tray count, occupied cells and measured cell volume.
Common uses
- How much measured cell volume do my plug trays hold
How it works
Multiply trays, occupied cells and milliliters per cell, divide by 1000 and apply the user allowance. Cell volume is measured or supplied; compaction, settlement and losses are not predicted. Measured quantities and user-selected spacing only; no crop, watering, chemical treatment or growing recommendation is provided. Biological outcomes can differ.
Worked example
Enter Tray count: 4 trays; Occupied cells per tray: 72 cells/tray; Measured volume per cell: 40 mL/cell; Extra volume allowance: 10 %. Results: Nominal cell volume: 11.52 L; Volume including allowance: 12.672 L.
