My slightly overengineered hydroponics farm is nearing completion.
The middle part rotates, so there's four sets of farm plots, with two columns on four sides of the octahedron. The idea was to have the whole thing slowly rotate while in the growth phase, yet keep the whole thing vacuumproof.
For harvest, the inner cylinder can be stopped and aligned with the entrance. The collector arms on each side can then extend and sweep through the crops to vacuum the spoils.
