Earn mastery by harvesting

Each seed crop harvested advances that seed’s raw mastery harvest count once. A Level 25 plot that produces five items still counts as one base harvest for mastery. Auto Cropper counts. Greenhouse and active mastery companions add fractional harvest-equivalent progress. Supplier paths can add 0.1 mastery per seed produce delivered in orders.

Cadence-specific requirements

The extra progress for mastery level M is round(cadence base × 1.5^(M−1)), with a minimum of one. Requirements are cumulative. The cadence base comes from that seed’s catalog, so use its individual page for the exact full threshold table.

What mastery adds

Each mastery level adds 2% of the seed’s original base HP, rounded up as a combined mastery bonus. Mastery 20 is +40% of base HP. This is added to the seed-level value before matching weather. It does not reduce growing time. A Greenhouse stat such as “20% extra Mastery progress” increases progress speed, not the point bonus per mastery level.
