Rutabaga

Unlocks once you've harvested 590 Rhubarb, 470 Kale, 340 Blue Corn and 140 White Pumpkin in all; unlocking it is then free.

A seed costs 92 spare parts and grows for 15m 12s (12m 10s on fertilized soil), needing water 13 times on the way: it stops growing until it's watered. It gives 20 harvests, growing back from scratch after each one.

Each harvest is one Rutabaga and 25 spare parts: 500 from one seed, 408 more than it cost, over 5h 4m of growing. In a Biofuel Converter each one is worth 18 biofuel.

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