This idea and set up is very week at the start and only gets good close to the end. But planning for the last stage of adding population to a planet can quickly be helpful. This is a planning a head type of set up. I would not suggest you do start adding this into a planet set up till you have at least Hypersphere Habitat as the increase in pop is more worth it. Though ill be including all set ups week or not.

I try and have enough space so once I get my Topopolis Rings (I am prety close) I will have the space for one if not two depending on the planet. Ill go threw a single ring growth set up and then a two ring growth set up. The idea is to max population till the very last building. This is showing what keeping within the rings size and how to max it for both type of end set ups. So six and twelve spaces is the goal.

Planet buildings researched
Building +# built (added population)

One Topopolis Ring set up

Habitation Modules only
Habitation Modules +6 (+120 population)

Habitation Modules and Arcology only
Arcology +3 (+225 population)

Habitation Modules, Arcology, and Hypersphere Habitat only
Hypersphere Habitat +2 (+400 population)

Habitation Modules, Arcology, Hypersphere Habitat, and Astrocore Habitat only
Hypersphere Habitat +2 (+400 population)

Habitation Modules, Arcology, Hypersphere Habitat, Astrocore Habitat, and Trans-Hub Habitat only
Trans-Hub Habitat +1
Habitation Modules +1 (+670 population)

Habitation Modules, Arcology, Hypersphere Habitat, Astrocore Habitat, Trans-Hub Habitat, and Topopolis Rings
Topopolis Rings +1 (+1,000 population)


Two ring growth set up

Habitation Modules only
Habitation Modules +12 (+240 population)

Habitation Modules and Arcology only
Arcology +6 (+450 population)

Habitation Modules, Arcology, and Hypersphere Habitat only
Hypersphere Habitat +4 (+800 population)

Habitation Modules, Arcology, Hypersphere Habitat, and Astrocore Habitat only
Astrocore Habitat +3 (+1,200 population)

Habitation Modules, Arcology, Hypersphere Habitat, Astrocore Habitat, and Trans-Hub Habitat only
Trans-Hub Habitat +2
Arcology +1 (+1,375 population)

Habitation Modules, Arcology, Hypersphere Habitat, Astrocore Habitat, Trans-Hub Habitat, and Topopolis Rings
Topopolis Rings +2 (+2,000 population)


Might not be a total winning set up, but it is something that can help in the long run. But these set ups only start to get good at Hyperspheres, till you get that building you are always better maxing out production as this building type is not worth that much till then.
