Needs to already have a town with room for said farm/plans to start a farm, Size will be anywhere from 32x32 - 64x64
I'm not exactly sure of the purpose of this farm but your post reminded me of a tutorial I made a really long time ago. https://www.ecocitycraft.com/forum/threads/how-to-farm-netherwart-the-easy-and-efficient-way.72847/ I would advise using long rows like the ones in the tutorial. It is much more efficient than having a big square. I also sell perms to an all-crop farm that has nwart in this configuration, but the nwart farm honestly isn't the best. I never focused on it much because I don't know anyone other than myself that farms nwart. Other than that, I can't help you too much but I wish you good luck!
