Opal Mutation �?Grow a Garden
The Opal mutation multiplies a crop's value by ×21. Here's how it works and what it's worth.
What is the Opal multiplier?
In Grow a Garden, the Opal mutation has a multiplier of ×21 and belongs to the Gem group. Use the Crop Value Calculator to apply it to any crop and weight.
How Opal stacks with other mutations
Opal stacks additivelywith other non-variant mutations: the game adds up each mutation's bonus rather than multiplying them all together. On its own it gives ×21; combined with others, it adds 20 to the shared multiplier. A growth variant (Gold ×20 / Rainbow ×50) then multiplies the whole thing.
Opal value example
A base-weight Carrot (20 Sheckles) with the Opal mutation is worth about �?420 Sheckles. Add weight and more mutations in the calculator to get your exact number.
