Increases Psych output at base by 50% and produces the same amount of energy as 50% of the energy at base less that lost to inefficiency. Increases nutrient output in forest squares by one. Eliminates at least half the ecological damage caused by terraforming (farms, mines, roads, etc.).
If constructed after a faction’s first report of fungus growth, the amount of minerals that can be produced by any of that faction’s bases before causing ecological damage will be increased by one. This effect is permanent even if the facility is destroyed or the base lost.
