Cabbage

Unlocked from the start. Every new farm starts with two planted for free in its first crop patch.

A seed costs 2 spare parts and grows for 2m 30s (2m on fertilized soil), needing water twice on the way: it stops growing until it's watered. It gives 3 harvests, growing back from scratch after each one.

Each harvest is one Cabbage and 3 spare parts: 9 from one seed, 7 more than it cost, over 7m 30s of growing. In a Biofuel Converter each one is worth 2 biofuel.

A Reaper chip can improve its grow time, watering, harvests, biofuel or earnings.
