Is it possible to make a nether wart farm outside of the Nether

Minecraft 1.3+
As long as Nether Warts are planted on soul sand, they can grow in any world.


Pre-Minecraft 1.3 No. You can bring Soul Sand out of the Nether into the Overworld, and you can plant Nether Wart Seeds into it, but they will not grow. They will only grow if it is done in the Nether.
