It's just materials at this point. As I don't have polymers really (yet) my first dome became:
3 x Residences
1 x Farm
Diner, Infirmary, Grocer, Small Alleys
This gives me a max pop in the dome of 42. I shipped in 24 people and it's currently 39/42 so quite a few martians which is nice. This dome is double shifting my rare metals extractor, and single shifting my machine parts factory, I could double shift that as well but it's incredibly expensive on power.
I have 14 polymers left, and I can buy some more, but it will be a little while before I can get the rocket over, and I need 10 for the Dome I want to construct.
I need to sort out my water problem. Right now I am relying on one water extractor which isn't high quality and doesn't have a lot left. I may try to replace my production with water vaporators as much as I can, I can then store lots in tanks and possibly disable the water extractor, re-enabling it only as needed. I'd like to ship some more stirling generators to lower power maintenance costs, especially with a second dome going up.
For the Polymer manufacturing, I can hopefully build that into a closed loop. With polymer factory, water vaporator, and a single solar panel effectively off-grid. I believe I can construct this within my heater range which will help a lot during the stupidly long cold waves.
Extend the range of the heater. It can cover quite a bit.
