Mission performed on a reclaimed farm inside your fort. Increases the amount of food the farm produces every day. Increases the Scavenging skill.
Amount of food produced per day= 0.5*(number of farms being farmed)+0.5*(number of farmers)+0.25*(total scavenging skill of farmers)
(this is based on impossible level, since food production on other difficulties is not really a problem)(actually, nothing is really a problem if not on impossible.)
(A big/huge farm counts as 1 farm)
The effect green thumb perk hasn't been tested.
