Worked Radish example

Radish has 12 base HP. At Seed Level 10, its leveled value is floor(12 × 1.54) = 18. Mastery 20 adds ceil(12 × 0.40) = 5, for 23 before weather. A matching Cool Front adds 20%, so planting records floor(23 × 1.20) = 27 HP. With a max Windmill, that weather boost becomes 30% and the recorded value is floor(23 × 1.30) = 29. This example excludes other companions and late harvesting.

Why the card and inventory differ

A seed preview can show today’s upgraded or weather-boosted value. Inventory shows the value actually recorded for that batch after its planting and collection history. Different batches of the same produce may therefore have different HP. A +25% weather bonus is a positive boost, but a crop harvested late may still end below an unpenalized preview. Orchard fruit uses its own fixed per-fruit HP instead of this seed formula.
