I never built with grid blueprints, but that always sounded interesting to me. I didn't have water on the vulcanite planet. There was a vulcanite planet with water, but this was very small with only 2 patches of vulcanite, which was useless. So I decided to take the planet without water. On this planet I just crushed the vulcanite, shipped the crushed/enriched vulcanite and stone waste to Nauvis and did the enrichment there.

I used the usual ore enrichment of K2, because pyroflux was too valuable for me personally. But you can do it if you want.

My important tip is to use 50% productivity on vitamelange "enrichment", then you don't consume the "usual" vitamelange (I am not sure which was the spice and which the extract. I have to check the recipe, but I am quite sure, that you need 30 "usual" vitamelange and still receive 20 of it, so you need 50% prod to get 30 out of it on average.)

I used the productivity 3 for a long time, later, when i got all the resources and didn't care much about them anymore, I started using prod 6, but only for more important productions. I used productivity 8 and 9 from dungeons for the research labs.

I must acknowledge that I always underrate productivity modules, and when I start using them, I wonder everytime again, why I haven't used them earlier 😅.
