Resource buildings ratio, Resource Converter, Monolith Facilities and Stellar Manipulation

It's actually called a Monolith Facility, not Moonlight. On a planet with decent resource values across the board, you'll generate more total resources with Monolith Facilities. You'll be wanting to use a Resource Converter to translate those extra organics and radioactives into minerals. I forget where exactly the convert order is located, but you should be able to access it through the right-click menu when you have a planet with a converter selected.

As for the ratios you mentioned, I never worried about ratios, what I did was just make it even (which might be wasteful I don't know but I never had a problem with resources). I would look in my Empires tab and see my total production of resources and try to make them all about even. Anyways, that ratio thing is only good if you are not an Organic or Crystalline race, I think. Not sure about stock, but atleast with alot of mods Organic races use quite a few more organic resources than any other and Crystlaline races use radioactives the same way.

I rarely end up using Stellar Manipulations at all but I think they are pretty expensive in research points (atleast for the later tech levels) that its a mid to late game science pump thing. Certainly its not something you should be worried about in the early game.

In SE4, you could set a planet with the convert resource order to repeat orders, which would do it automatically every turn. Not sure if that carried over to SE5 - I'd assume it does, but I haven't tried it myself.

Never used ratios either. Simply put, I put SY and Resource facilities on all "green" colonies and nothing but Research on the "red" planets. That has always worked quite well for me.

I use the crystaline tech tree, so provided i find a few double or triple star systems to stock up solar collectors in, i use every decent mineral value planet not in these systems for minerals and pile research facilities onto the rest, never really having to build a radioactives facility if i get lucky enough. makes for plenty of all the resources usually and a lot of research points too, but you have to invest some race points into the crystaline trait. its pretty nice i think because it doesn't seem to rely on planet value %s, and you can build them all over and get massive goods and have plenty of space in other systems left for research, i guess it would be bad though if you were playing multiplayer and one of these solar collector systems gets glassed, you would prob get screwed if you didn't protect it well.

I like Organic and Crystalline because they improve the spread of resources. It actually speeds up ship construction!

Ship A: Mostly minerals
4500 M, 200 O, 400 R : Total = 5100

It requires 4500 construction points to build.

Ship B: Mixed
3000 M, 1500 O, 1500, R: Total = 6000

This one only requires 3000 construction points. Sure the total cost is higher, but it gets built 33% faster.
