Buck Capsule (A) ranks among the most profitable products you can craft in Valley IV, but setting up its production chain is a major space and resource commitment. The blueprint described below occupies roughly 40% of a fully upgraded base's buildable area and cannot be saved as a blueprint, so you'll need to build it manually. The layout splits into two parallel production lines: one for Double Steel Bottles and one for Ground Buckflower Powder. All materials are produced on the main AIC floor, fed by 10 Bus Depot Unloaders configured with 8 Ferrium and 2 Sandflower outputs each. This design minimizes depot bus usage, leaving room for other standalone chains.

The Steel Bottle Sub-Line

The Steel Bottle chain processes Ferrium Ore and Sandflower in a specific sequence. Start with Ferrium Ore: send it through a Refining Unit, then a Shredding Unit, then a Grinding Unit, another Refining Unit, and finally a Moulding Unit. For Sandflower, route it through a Shredding Unit (which outputs 3 Sandflower Powder every 2 seconds) into a Protocol Storage Stash, then to the Grinding Unit. One Sandflower Shredding Unit can support two Grinding Units; add a second Protocol Stash to stockpile excess powder. This setup produces 60 Steel Bottles per minute, exactly the rate needed to sustain Buck Capsule (A) production.

The Ground Buckflower Powder Sub-Line

Buckflower and Sandflower come from a self-sustaining farm on the main floor. Build four identical modules, each consisting of one Seed-Picking Unit connected to two Planting Units. Two modules grow Buckflower, the other two grow Sandflower. In each module, one planter sends its output to a Shredding Unit, while the other loops back to the Seed-Picking Unit to ensure an unlimited seed supply. To meet demand, you need two parallel chains, each feeding a Buckflower chain and a Sandflower chain into a single Grinding Unit to produce Ground Buckflower Powder.

Final Assembly

Once you have both the Steel Bottles and the Ground Buckflower Powder flowing, connect them to a Filling Unit. The finished Buck Capsules (A) go into a Protocol Storage Stash, yielding 6 units per minute. If you're tight on floor space, you can delegate raw material production (steel, flowers, etc.) to Outposts across Valley IV. However, this won't reduce the number of Depot Bus Unloaders required; it may even increase it.

The chain is large but straightforward. Its main challenge is the physical footprint—plan your AIC layout carefully before committing to this production line.
