Arid Epigenetics is a technology on the Exploration and Expansion technology tree. With a research cost of 40 , it unlocks one Colonization option and allows further research in Compact Fusion Reactors and Sustainability.
"The ability to permanently apply grafted or genetically engineered traits into the DNA of succulent plants has great, long-term advantages for simplifying colonization."
- -100% on Population growth on Star System
"The discovery of arid plant epigenetics encourages succulent plants (cacti, agave, etc.) to self-evolve in order to better adapt to extreme conditions. It also permits many cash crops to grow in previously impossible biospheres."
- Remove the colonization penalty on that planet type
Sowers can always colonize any planet type, but suffer a penalty until they research the appropriate technology.
