Stack growth and environmental mutations to find the combined multiplier in Grow a Garden, and apply it to any crop’s base value.
How grow a garden mutation is worked out
Mutations are where Grow a Garden values explode. This mutation calculator lets you pick a growth mutation and tick every environmental mutation, then shows the combined multiplier the way the community stacks them — so you can see what a Rainbow crop covered in high-tier mutations is really worth.
Environmental mutations don’t each multiply on their own; they add together as 1 + (sum of multipliers − count), and that result is multiplied by the growth mutation. Enter a base value to see the final number, or leave it blank to just read the multiplier.
Try it with these numbers
The calculator opens with a growth mutation of 1, environmental mutations of on. On those figures the total multiplier is ×1. Underneath, Growth × comes out at ×1 and Environment × at ×1. Change any field and every figure updates as you type.
How to fill it in
- Pick the growth mutation — None, Gold ×20 or Rainbow ×50.
- Tick every environmental mutation the crop has; the tool stacks them for you.
- Optionally enter a base value to see the mutated value, and read the total multiplier at the top.
