Radish

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

A seed costs 1 spare part and grows for 2m (1m 36s on fertilized soil), needing water 3 times on the way: it stops growing until it's watered. It gives 2 harvests, growing back from scratch after each one.

Each harvest is one Radish and 2 spare parts: 4 from one seed, 3 more than it cost, over 4m of growing. In a Biofuel Converter each one is worth 1 biofuel.

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