The corn plant has a long growing cycle and a very high yield of 27 pieces of corn. It cannot be sown in hydroponics. Corn plants have a base growing time of 11.3 days, need a minimum soil fertility of 50%, and have a fertility sensitivity rating of 100%.
The following table details how long it takes for corn plants to grow in each growable ground type, factoring in the plant resting time and being in ideal growing conditions:
|Ground Type||Gravel||Soil||Rich Soil||Hydroponics|
|Grow Time (days)||27.88||19.52||13.94||-|
Corn plants do not suffer the downtime between multiple harvests that rice fields deal with due to corn's long growing time. But this also makes it the most vulnerable to negative incidents (burns, bad weather, animals destruction). Corn should not be entrusted as the colony's only food supply without other alternatives. Corn's exceptional shelf life means that the colony does not need to invest in freezer space for corn, as even the slightest winter will keep corn fresh until next year's harvest. Thus a corn harvest only needs to be placed in a simple shed or under an outdoor roof.
