This is a three-part Vitemelange Spice and Extract production center. It will allow you to fill a warehouse full of both without deadlocking either. Wide-Area Beacons can be added with minor adjustments.
NOTE: This plan is using xkyouchoux’s Space Age Building Integration mods. If you are not using those, you will need to manually place Industrial Furnaces between the Greenhouses.
My best Vit world option is small, but high-threat, so I am somewhat space-constrained by defenses until I unlock Glaive Beams, at which point I will purge everything. If you have a similar problem, you can use this plan, and fit the modules where you can.
I am using one of Module 1, one of Module 2, and two of Module 3.
Factorio 2.0, Krastorio 2, Space Exploration 0.7x, stringweasel’s Valves mod, and xkyouchoux’s Space Age Building Integration mods. Should be easy to adjust without the last two.
You will need massive amounts of fertilizer, be prepared. The sand Module 1 produces will be helpful for that. I was not able to run this design at full capacity until I unlocked the Nutrient Gel-Fertilizer loop in B2.
