Minecraft wiki entry for Dripstone_farming, associated text: To be able to manually farm dripstone, all you will need is some dripstone blocks, an equal amount of pointed dripstone and 2 water buckets. First you will need to place the amount of dripstone blocks you want dripstones to grow from, and water sources a layer above that. Now plant pointed dripstones on the dripstone blocks, and the farm is done. To harvest it, every 20 minutes or Minecraft day, check on the dripstone and harvest the second parts of the ones that are 2+ high and also the stalagmites on the floor.
