🌋 Volcanic Mutation in Grow a Garden — ×25 Multiplier
Volcanic is a weather-triggered mutation with multiplier ×25. 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 Eruption.
Last verified . Multiplier and trigger come from this site's mutation dataset — we do not invent extra rates.
Ranked #52 of 108 tracked mutation pages by multiplier.
📌 When to use Volcanic
Farm Volcanic during the listed weather. If a pet is also named in the trigger, that pet is the off-weather path.
📐 How to Get the Volcanic Mutation
Trigger (from our mutation data): During Eruption.
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.
💰 Worked Examples: Volcanic 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 Volcanic 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 Volcanic Ranks
Volcanic is the #52 most valuable mutation out of 108 tracked entity pages by multiplier, sitting just behind 🌘 Moonbled (×25) and just ahead of 🧟 Zombified (×25).
The mutations hub calculator also lists mutations that do not yet have their own URL. This page is the entity URL for Volcanic only.
❓ FAQ
Does Volcanic use the homepage calculator formula?
Yes. Volcanic is a fruit modifier at ×25, 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 Volcanic mutation?
During Eruption.
Does Volcanic stack with Gold or Rainbow?
Yes. Volcanic 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 Volcanic 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 Volcanic into any crop, weight, and mutation stack for the real number.
