The Organic Space Yard is a base-only component that requires organics to build, so it takes 2-3 years to build with a space yard ship. It's just a somewhat improved Version of the base space yards available to non-organic races. It is a minor compensating advantage, because the other changes are a net disadvantage to organic races, which suddenly can't effectively build their weapons and armor techs with space yard ships.
