I present to you the ULTIMA FARM! No need to work, the villagers do it for you!
The farm does:
- Wheat Seed
Need 2 villagers for 1 layer. 1 farmer and 1 random (lock on the carpet)
The light placement makes 1 grass unlighted and the villager will be attracted by it for sow the missing place. But he can't.
