🍀 Luck Mutation in Grow a Garden — ×3 Multiplier
Luck is a weather-triggered mutation with multiplier ×3. Farm it during the listed weather (see the weather events hub), or use any pet/spray named in the trigger. It is not a growth mutation, so it can sit under Gold or Rainbow. Trigger: During Rainbow Event.
Last verified . Multiplier and trigger come from this site's mutation dataset — we do not invent extra rates.
Ranked #97 of 108 tracked mutation pages by multiplier.
📌 When to use Luck
Farm Luck during the listed weather. If a pet is also named in the trigger, that pet is the off-weather path. Low multiplier: keep it as a free additive if it is easy to apply; do not pause a bigger farm for it.
📐 How to Get the Luck Mutation
Trigger (from our mutation data): During Rainbow Event.
Watch the in-game forecast and the weather events list. Shops restock on a separate clock — use the stock tracker for Seed/Gear timers, not for weather. If a pet is named above, that pet can apply this mutation without the weather.
At ×3, Luck is a stacking chip, not a solo payday. Its value is the additive formula with bigger mutations (Shocked, Aurora, Disco) plus Gold or Rainbow on top.
💰 Worked Examples: Luck on a Sunflower
Numbers use the site formula Base × (Weight/BaseWeight)² × Growth × (1 + Σmutations − count) and Sunflower's listed base. Plug a live crop into the Grow a Garden calculator for other weights.
🔗 Stacking & Best Combos
Once Luck is on a fruit it follows the additive rule with other non-growth mutations: 1 + Σ(multipliers) − count. Gold (×20) or Rainbow (×50) then multiplies that total. Cleaning Spray (Gear Shop, listed on stock) can strip mutations if you need to rebuild a fusion.

❓ FAQ
Does Luck use the homepage calculator formula?
Yes. Luck is a fruit modifier at ×3, not a crop and not a pet. Plug it into the Grow a Garden calculator with a real kg. This FAQ does not repeat the intro paragraph.
How do you get the Luck mutation?
During Rainbow Event.
Does Luck stack with Gold or Rainbow?
Yes. Luck is not a growth mutation, so Gold (×20) or Rainbow (×50) can multiply it. With other environmental mutations it uses 1 + Σ − count first, then growth.
What crop should I put Luck on?
Any crop uses the same multiplier. Worked examples on this page use Sunflower (50,138₡ at 8.55 kg) because that crop is also the Dawnbound reference. Weight² usually moves the number more than swapping a mid-tier crop.
Plug Luck into any crop, weight, and mutation stack for the real number.
