Garlic

Unlocks once you've harvested 390 Spinach, 420 Broccoli, 330 Red Chili and 200 Red Onion in all; unlocking it is then free.

A seed costs 27 spare parts and grows for 8m 40s (6m 56s on fertilized soil), needing water 6 times on the way: it stops growing until it's watered. It gives 13 harvests, growing back from scratch after each one.

Each harvest is one Garlic and 15 spare parts: 195 from one seed, 168 more than it cost, over 1h 52m of growing. In a Biofuel Converter each one is worth 11 biofuel.

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