We have spawned underground after the apocalypse. Unable to return to the overworld we must survive on limited resource with the goal of becoming self sufficient.
In this episode we explore the Nether and create a simple and effective automated wheat farm.

In the video I mention not to use more than 1 villager in the farm. This was not correct. You can use more than 1 but make sure his inventory slots are also full of seeds.
