Home planet

My home planet will soon have 162 out of 163 fields and I need to get some Terraformers going, but I was wondering what levels should all my buildings be at when I'm done building up Nanite factories and tearing down anything else I don't need, while still allowing for a lvl 12 shipyard to be able to build deathstars.

Currently my home planet has this,

Metal mine - 27
Crystal mine - 25
Deuterium synthesizer - 20
Solar plant - 27
Fusion reactor - 4 (I don't think its even worth having)
Metal storage - 9
Crystal storage - 8
Deuterium storage - 7
Robotics factory - 10
Shipyard - 9
Research lab - 10
Missile silo- 5
Nanite Factory - 1

Personally I'd save 4 spaces straight away by de-constructing your Fusion reactor. As long as you have at least 1 Plasma Turrets per solar sat and don't keep you fleet or loads of resources parked there the solar sats should be safe.

The first 3 levels of Terraforma are quite cheap and you can build as soon as you fill the slots recovered from your Fusion Reactor. Your solar plant should be increased to lvl 30 so you are not too dependant on solar sats.

After that the resources may be better spent on Astro Research for a new planet rather than trying to keep expanding this one.
