- "Harvest is when I need you the most. Only one more season. This year we'll make enough on the harvest so I'll be able to hire some more hands."
- ―Owen Lars, to Luke Skywalker
A moisture farm was an area of land devoted to the production of water through the drawing of moisture from the dry air. It depended on vaporators, a type of device that could harvest excess atmospheric humidity. On hot and arid desert worlds like Tatooine, moisture farming was a vital activity. The Lars family, into which Luke Skywalker was adopted, owned one such farm. The family of Biggs Darklighter was rich enough to own twenty.
Banthas were sometimes employed on moisture farms. Droids were useful on moisture farms too. Owen Lars purchased the droids C-3PO and R2-D2 because of C-3PO's ability to speak Bocce and the binary language of moisture vaporators and, in the case R2-D2, because of the general utility of an astromech droid.
