THE FORMULA

How the result is calculated

Seeds needed = target plants ÷ (germination rate × survival rate). The result is rounded up to a whole seed.

SproutScale preserves full precision while calculating and rounds only the displayed result or the final purchasable unit.

FIELD NOTES

Before you act

  • Use the packet's current germination test when available.
  • Allow extra seed for direct sowing where weather losses are likely.
  • Store leftover seed cool, dry and clearly labeled.
QUICK ANSWERS

Seed quantity FAQ

Why include survival after germination?

Not every seedling reaches transplant or harvest size. A separate survival assumption makes that loss visible.

Does this account for thinning?

No. If you intentionally sow multiple seeds per station, multiply the result by that sowing practice.
