In Grow a Garden (Roblox), mutations will increase the value of your crops by a standard multiplier.
They also change the look of your crops, like color, texture, glow, particle effects, and more.
Mutations are triggered when weather events occur, using tools, or planting special seeds.
Most mutations can be obtained automatically when the crop is growing or fully grown.
In this guide, you’ll learn what the Radioactive mutation in Grow a Garden (Roblox) is, its multiplier, how to get it, a wiki, and more.
Grow a Garden Radioactive Mutation Multiplier

The Radioactive mutation gives crops an 80x multiplier and turns them neon green in color.
Crops can obtain it during the Radioactive Carrot admin weather event.
During the event, players need to give carrots to the Carrot Rocket.
Once 100 carrots are given, the rocket will launch, an acid rain will occur, and crops can obtain the mutation.
