A row of buckets, each one a complete machine, none of them plumbed to another.
A modular, expandable water cooling system for a retail flower shop. Each bucket is its own station: its own reservoir, its own pump, its own sponge filter.
The unit is the bucket, not the row. Water circulates inside a station and stays there — no shared tank behind the line, nothing running between one bucket and the next.
That is what modular and expandable has to mean. A station is complete on its own, so the shop can run one or run a row, and the row is the same design either way: the second station is the first one again.
The first build is deliberately barebones — one chilled bucket beside one at room temperature. One variable, one comparison.
What the shop wants out of it is a parts list and a plan. The larger idea, a flower vending machine, is parked behind this test.
Three parts, one bucket, and nothing crossing the gap.
Its own reservoir
The water for a bucket lives in that bucket. Nothing is drawn from a tank the whole row depends on.
Its own pump
One pump per station. The bucket is the unit that runs, and the unit that doesn't.
Its own sponge filter
Filtration per station too, working on water that never leaves it.
Simplified to barebones: one chilled bucket versus room temp.
Cut back to the smallest build that answers the question. A parts list and a plan are wanted from it, and the vending machine idea is parked until it works.

The parked machine
A DIY flower vending machine — insulated glass display, touchscreen picker, an arm to assemble bouquets, a Raspberry Pi and cameras. Fun, but after the bucket test works.
