All of your bases enter a permanent state of population boom and will grow
every turn provided nutrient output is sufficient and Hab facilities ( Hab
Complex / Habitation Dome ) are adequate
The negative effects of the Power and Thought Control social engineering
choices are eliminated
For whatever it's worth, this tends to be the earliest
500-point project to pop up. It's a useful and diverse asset to your faction,
but requires some careful management. The population boom effect can be useful
in becoming a dominant faction, but all those extra citizens can be a pain to
deal with, especially if you're already facing drone trouble. The University
in particular, with it's drone-prone ways, should make preparations ( in the form
of psych-enhancing base facilities ) before building this one.
The Cloning Vats work particularly well in conjunction
with the Planetary Transit System, allowing you to
grow brand-new bases to significant size in jig time.
The more subtle side of this project is it's effect on
Social Engineering. In addition to eliminating all negatives from the Power and
Thought Control choices, it also, by nature, makes the Growth social factor more
or less irrelevant. Building this project allows you to go to a Green/Power/Thought
Control system with no negatives whatsoever - perfect for a late-game conquest
drive. The vats make Planned and Eudaimonic choices just a little bit less appealing,
because it makes these choices' bonuses to growth irrelevant ( which is not a
problem, really, but you may want to think about a choice with a bit more bang
for your buck ).
If you're trying to control your population, give this
one a pass. It will be of some use to most other factions, but only if proper
preperations are made.
