The growth stimulator is a superior form of the growth accelerator. It is deployed to the battlefield by the aggressive Reaper-17 sect.
Like a standard Growth Accelerator, it accelerates the growth of Tiberium by 50% and can only be built on the chasm in middle of a Tiberium field. The Growth Stimulator is equipped with four additional Tiberium-processing devices similar to the Scrin Extractor. Because of this, it mines Tiberium from underground in a similar manner to the Tiberium Spike, providing 15 credits of income every 5 seconds.
