Broccoli

Unlocks once you've harvested 530 Potato, 370 Turnip, 260 Green Peas and 50 Eggplant in all; unlocking it is then free.

A seed costs 16 spare parts and grows for 7m 18s (5m 50s on fertilized soil), needing water 8 times on the way: it stops growing until it's watered. It gives 10 harvests, growing back from scratch after each one.

Each harvest is one Broccoli and 11 spare parts: 110 from one seed, 94 more than it cost, over 1h 13m of growing. In a Biofuel Converter each one is worth 8 biofuel.

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