Rainbow Moon Weather

Spawns Rainbow Seeds; chance to apply the Rainbow mutation

Rainbow Moon 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 Rainbow Moon are not individually documented in our sources. Watch the in-game sky indicator or the weather broadcast.

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

• Rainbow·×30 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 Rainbow Moon 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.
