Aurora Borealis Weather

Night-time weather event that has a chance to apply the Aurora mutation to crops. Lasts approximately 2 minutes. Reported proc chance for the Aurora mutation is ~1.5%.

Aurora Borealis is categorised as a Special weather event in Grow a Garden 2. It is part of the rotating server-wide weather system, where each event applies a temporary rule to the garden — usually a chance to apply one or more mutations to ripe crops.

Duration: ~2 min

Weather events in Grow a Garden 2 rotate server-wide; the exact trigger conditions for Aurora Borealis are not individually documented in our sources. Watch the in-game sky indicator or the weather broadcast.

While Aurora Borealis is active, ripe crops have a chance to roll one of the following mutations:

• Aurora·×90 sell multiplier
  Likely

Weather mutations stack additively with each other, so if two weather events happen to overlap, the roll value compounds. See the mutation system explainer for the full stacking formula.

The optimal play during a Aurora Borealis window is to have high-value multi-harvest crops ripe on the plot when the event starts, so the mutation roll has the widest possible target set. Crops with a high base sell value benefit most from a multiplier roll; cheap crops gain little.

Pair the window with relevant pets and gears that compound the benefit. The value calculator lets you model the multiplier on your specific crop; the weather events guide covers timing and stacking with other weather mutations.
