The Growth Accelerator

The Growth Accelerator massively accelerates the growth of certus or amethyst when placed adjacent to the budding block.

Curiously, it can also accelerate the growth of various plants.

To power it manually, place a Wooden Crank on the top or bottom and right-click it.

It only connects to cables on its ends where the pink fluix greebles are.
