Growth Time & Chance

You can define the time growth to the next stage, and the chance a stage will grow at all.

Growth Time

The time this stage takes to grow into the next one.

# hours, minutes, seconds
growth: 3h 12m 3s

# just minutes and seconds
growth: 12m 3s

# just seconds
growth: 3s

# or in ticks
growth: 60

Growth Chance

The chance for the generator to grow into this stage.

chance: 0.5   # 50%

chance: 0.2   # 20%

If you change the stage type to regrown, and specify a chance, then if the chance is true the generator will grow into the stage and stay there until harvested instead of keep growing.
