Green Grapes

Unlocks once you've harvested 440 Oats, 290 Watermelon, 270 Sweet Potato and 110 Red Grapes in all; unlocking it is then free.

A seed costs 60 spare parts and grows for 13m (10m 24s on fertilized soil), needing water 8 times on the way: it stops growing until it's watered. It gives 17 harvests, growing back from scratch after each one.

Each harvest is one Green Grapes and 21 spare parts: 357 from one seed, 297 more than it cost, over 3h 41m of growing. In a Biofuel Converter each one is worth 15 biofuel.

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