There's nothing better than automating all the crop farms in Minecraft. Work smart, not hard.
This farm is easy to build and can produce you: carrots, potatoes and Beetroot. The rates get up to 850 items per hour and it's fully automated!
I do not recommend using this design for wheat. Use my other design instead: https://youtu.be/IWbBvLsVRj0
