Site and operating requirements

  • Identify crop, season, water quality, soil/medium and local heat. Measure materials before cutting and confirm support and drainage.

Tools and measuring equipment

  • Labels, marker and germination log
  • Thermometer and small measuring cup

Output and operating conditions

A 10-seed check gives a coarse percentage: germinated seeds ×10. Eight out of ten is 80%, not a laboratory certificate.

Dry orthodox vegetable seeds only. Some species need special dormancy treatment or cannot tolerate drying; follow crop-specific guidance.

Parts, quantities and dimensions

PartQuantitySpecification / dimensions
Clean sealed plastic storage box1Small dry box with labelled paper seed envelopes and separated desiccant; cool storage around 0–5°C suits many vegetable seeds.
Paper towel and clean test container1 per lotA damp, not dripping, towel inside a sealable plastic test box.
Seed sample, labels and marker10 per testUse a representative sample and note species, cultivar, lot and harvest or purchase date.

Preparation and component checks

  • Keep chemical-treated seed visibly separate.
  • Read species-specific dormancy and temperature requirements.

Procedure

  1. 1

    Keep seeds from healthy plants or reliable lots and identify whether drying and cold storage suit the species.

  2. 2

    Dry suitable seeds fully according to crop guidance and place labelled envelopes in a sealed dry box.

  3. 3

    Store cool and stable; let a chilled closed box warm before opening to reduce condensation.

  4. 4

    For testing, spread ten seeds on a damp towel, fold it and place in the labelled test box.

  5. 5

    Hold at the crop’s germination temperature, check moisture and record new germination until the specified interval ends.

  6. 6

    Calculate the result, compare lots and obtain fresher seed if performance is too poor for the intended planting.

Ready-to-use checklist

  • No condensation or unidentified seed in storage.
  • Planting quantity uses the measured coarse germination result.

Safety and inspection

Keep treated seed away from food, children, livestock and birds. Do not eat germination-test sprouts. Hybrid seed may not reproduce the parent traits.

Verify the result

Use the seed packet’s temperature and test duration. A 10-seed sample is a planning check and can miss lot variation.

Measurement log

  • Lot identity, storage dates and conditions.
  • Test count, days, temperature and percentage.

Maintenance and repeat checks

  • Inspect stored lots for condensation, insects and damaged seals; replace desiccant as directed.
  • Test again before a valuable sowing and keep lot histories separate.

Troubleshooting

Unexpected decline, pests, odour, poor growth or animal distress
Pause the affected activity, separate suspect material and check the guide’s moisture, heat, hygiene, drainage and care requirements. Get a qualified diagnosis before treatment or reuse.
