Germination Rate
Expert Tip
Seeds lose viability over time. Test older seed batches (2+ years) by placing 10 seeds on a damp paper towel in a sealed zip bag for 7-10 days.
Calculation Methodology & Details
Formula
Calculates the percentage of seeds that successfully develop sprouts. Rates below 70% indicate weak batch viability; increase planting counts accordingly.

How to Run a Seed Germination Test
Follow these steps to measure seed viability:
Count Sample Batch
Count a clean sample (usually 10 or 50 seeds) from the packet.
Provide Moisture & Heat
Place inside a damp paper towel inside a sealed plastic bag at 20-22°C.
Count Germinated Sprout
After 7-14 days, count how many seeds have grown healthy roots.
