Hey! This is a bone meal farm that produces around 6-7k items an hour! It was originally designed by Ilmango and tutorial by me.
It is a bit laggy farm, but that depends on the device you're playing on!
The farm can be easily expanded by extending some of the redstone lines and adding more modules! Don't build 2 farms!! Just extend the first one and the result will be less laggy and more effective!
Ilmango explains really well how to do that! -> https://youtu.be/T5-vtC_w38Q?si=LFlZZ2AoUplwmqgS
Make sure to NOT leave the loaded chunks while the farm is running, otherwise, it will break!
