Turn a simple paper-towel germination test into a practical sowing adjustment.
Use this as a planning estimate. Verify product labels, local conditions and supplier packaging before buying or applying materials.
Germination rate = sprouted seeds ÷ tested seeds × 100. The sowing multiplier is 100 ÷ germination percentage.
SproutScale preserves full precision while calculating and rounds only the displayed result or the final purchasable unit.
It is usable for many garden crops; sow roughly 1.25 times the target number, then adjust for field conditions.
You can, but a larger sample gives a more reliable percentage.
