🌀 Tempestuous Mutation in Grow a Garden — ×12 Multiplier
Tempestuous is an environmental mutation — fusions and aging chains such as Frozen, Clay, Ceramic, and the Amber stages. Multiplier ×12. Once applied it stacks additively with other environmental/weather/pet mutations (1 + Σ − count), then Gold or Rainbow can multiply the total. Trigger: Fusion of Windstruck + Twisted on the same fruit, or Pterodactyl pet. Tempestuous (×12) fuses Windstruck + Twisted, or comes from Pterodactyl. Useful as a constructed environmental, not a top-end chase.

Ranked #68 of 108 tracked mutation pages by multiplier.
📌 When to use Tempestuous
Tempestuous is a fusion/aging environmental mutation. Build the ingredients on the same fruit; Cleaning Spray undoes a mis-stack.
📐 How to Get the Tempestuous Mutation
Trigger (from our mutation data): Fusion of Windstruck + Twisted on the same fruit, or Pterodactyl pet.
Fusions need both ingredients on the same fruit (Cleaning Spray can remove a mutation if you mis-stack). Amber ages on the plant; do not harvest if you are waiting for Old/Ancient Amber.
💰 Worked Examples: Tempestuous 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 Tempestuous 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.
📊 Where Tempestuous Ranks
Tempestuous is the #68 most valuable mutation out of 108 tracked entity pages by multiplier, sitting just behind 👻 Veil (×14) and just ahead of 🟠 Amber (×10).

❓ FAQ
Does Tempestuous use the homepage calculator formula?
Yes. Tempestuous is a fruit modifier at ×12, 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 Tempestuous mutation?
Fusion of Windstruck + Twisted on the same fruit, or Pterodactyl pet.
Does Tempestuous stack with Gold or Rainbow?
Yes. Tempestuous 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 Tempestuous 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 Tempestuous into any crop, weight, and mutation stack for the real number.
