Outer Ring
Harvest multiplier19×
The Outer Ring is the highest tier at a 19× harvest multiplier — the best placement for late-game profit. Reserve it for your highest base-income crops (Secret, Exotic, Transcended seeds) where the long grow times are worth the wait. Pair Outer Ring crops with a Rainbow or Cosmic mutation during an event for the biggest harvest spikes in the game.
The Saw upgrade adds roughly +2× per level on top of the ring multiplier, so total income is base income × ring × saw × mutation.
