Seeds are grouped by the time it takes to fully grow. There are three different speeds, which take 24 hours, 48 hours and 72 hours (a greenhouse halves the time, planting inside is a 10-fold increase). These seeds also happen to be grouped by price, as shown in this table.
|Cost||Outside Time||Greenhouse Time||Inside Time|
|6-10 gold||24 hours||12 hours||240 hours|
|16 gold||48 hours||24 hours||480 hours|
|30 gold||72 hours||36 hours||720 hours|
For maximum yield, seeds have to be watered a total of four times, at the appropriate time. The first watering occurs when the seed is planted. Subsequent waterings occer in every third of the growing time. The first third starts immediately after planting, so the easiest time to do the second watering is immediately following planting.
|Speed||Second Watering||Third Watering||Fourth Watering||Harvest|
|Quick||0 to 8 hours||8 to 16 hours||16 to 24 hours||After 24 hours|
|Medium||0 to 16 hours||16 to 32 hours||32 to 48 hours||After 48 hours|
|Slow||0 to 24 hours||24 to 48 hours||48 to 72 hours||After 72 hours|
Remember that a greenhouse halves these times.
