Mutation reference

Grow a Garden 2 Mutations

Review the current mutation multipliers, how each mutation is triggered, and whether the value already feeds into the calculator. This MVP follows the corrected GAG2 rule: one crop can only use one active mutation at a time.

Current rule

Single mutation only. New mutation selections replace the current one.

This page, together with the calculator, now treats variant mutations and weather mutations as one exclusive slot. Do not add multipliers together. Pick the one mutation state that actually lands on the crop.

Calculator behavior

No mutation stacking

Every mutation listed below is treated as a replacement, not a stackable bonus.
