This is an example of what your farm would look like with my resource pack. It helps show what stage the netherwart are in so that you know when to harvest them.
Description
This allows you to see the nether wart stages individually by adding different colors to each stage.
Stage 1: Yellow
Stage 2: Orange
Stage 3: Red
Might not be much but I hope it helps :)
