Manufacturing

On the Governer page, you can increase your overall spending, and increase spending in a particular area of manufacturing, both of these will increase your manufacturing. For example, many people increase spending to 100% (it takes population and improved governement to increase this max level) right at the start, as well as shifting most if not all spending to manufacturing. That way, your next colony ship can get done in 3 (says 2) turns.

On Starbases, you can build modules which give manufacturing bonuses, they are listed in the second and the bottom button when a new constructor arrives. More starbases to help, but there's a limit beyond which extra production gets harder to come by. When you feel ready to worry about that, I suggest reading about "Economics in GalCiv" in the Encyclopedia first.

A little bit to start on

I have heard that people have seen minor civs get Manufacturing might for one planet that blots out more than one sector of a map.
Do these minors get certain bonuses in manufacturing cause i haven't gotten that big of a manufacturing might for one planet.

To get big production you can:
-have a good PQ to start with,
-build all the plants social improvements,
-put spending on 100%,
-have a lot of population on the planet (small effect wrt PQ)
-choose the industrialist party which adds another 20% prod,
-take + Prod picks,
-get the techs which add to production,
-hope for an event that said "do you want slaves for + 49% prod,
-build production enhancing starbases.

Minors can do any of these. I don't know how to see the minors' stats like Prod bonus etc. which you can spy on majors. Now, minors have nothing to do but boost their planets, so they probably build all sorts of plants there.

Remember than manufacturing costs money too, so most probably if you boost your planets, you won't be able to sustain max production without trading/extorting a lot.
