Rain / Thunderstorm — Plant large batches and wait for the Electric proc (×70). Thunderstorms are the highest non-event mutation source.
Frost — Ensure some crops are already Wet beforehand to trigger Frozen (×40). Pre-soak with Rain or Sprinklers.
Blood Moon — Time your largest harvest for this event. It fires every 4 hours and gives the maximum ×80 Bloodlit multiplier.
Aurora Borealis — Low multiplier (×1.5) but easy to trigger during the night cycle. Consistent bonus income opportunity.

Mega Moon is a night event that improves Mega Seed chances, not a standard mutation multiplier. Track its current data on the Mega Moon guide.
