When you harvest a cotton field you will obtain several units of Raw Cotton in your inventory depending on your field's level of Plenty (see Farming).
You may then process the Raw Cotton using the Crafting menu: Craft ⇒ Processing & Materials ⇒ Clean Cotton to separate each unit into 1 Clean Cotton and 10 units of Seeds of Cotton.
The meter levels of the field determines the tier of Cotton harvested (see Agriculture).
|Tier 1||Tier 2||Tier 3||Tier 4|
|Raw Yellow-Stained Cotton||Raw Indian Cotton||Raw Egyptian Cotton||Raw Sea Island Cotton|
