The Potato Plant is a domesticated plant which yields 14 potatoes at 100% growth. Requires 5.8 days (or 10.55 days when accounting for nightly resting period) with full light in optimal temperature range to reach maturity. It's high tolerance to ground fertility makes it efficient for growing in soil with poor fertility like gravel.
Potato plants are the default crops to be grown in newly-built hydroponics basins. It is, however, advisable to change this to rice plants since potatoes benefit little from hydroponics owing to their poor fertility sensitivity, therefore having a vastly inferior nutrition output to rice.
