With the new potion brewing system in Minecraft, I thought I'd set up a farm for Nether Warts, but there seems to be a logistics problem here.
If I plant 1 Nether Wart on some soul sand, and then later harvest it, I get 1 back.
In other words, there appears to be no way to actually farm these. Is this correct?
I have to hunt down strongholds and find fresh sources for them, which I use up when I harvest, and then I have to hunt some more?
Or is there something I'm missing here, some trick to get more than 1 wart out of 1 plant?
