Red Onion

Unlocks once you've harvested 380 Eggplant, 220 Pumpkin, 200 Broccoli and 80 Red Chili in all; unlocking it is then free.

A seed costs 18 spare parts and grows for 8m 20s (6m 40s on fertilized soil), needing water 6 times on the way: it stops growing until it's watered. It gives 11 harvests, growing back from scratch after each one.

Each harvest is one Red Onion and 13 spare parts: 143 from one seed, 125 more than it cost, over 1h 31m of growing. In a Biofuel Converter each one is worth 10 biofuel.

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