Guide:Chlorophyte Ore Farming

Chlorophyte Ore is one of the final ores available and is used to craft many end-game items. It can however, be somewhat uncommon in the Underground Jungle and large veins may take a long time to grow. Therefore, instead of searching through or seeding the Underground Jungle, players may wish to build a farm for Chlorophyte to give themselves a renewable supply of it.

Basic Requirements
In order to start with Chlorophyte farming, there are a couple of requirements:


 * Their world must be in Hardmode (enter Hardmode for your world by defeating the Wall of Flesh)
 * However, the player must defeat all three Mechanical Bosses (The Destroyer, The Twins, and Skeletron Prime) in order to craft a Pickaxe Axe or Drax, which is the minimum lowest-tier pickaxe or drill that can mine Chlorophyte. They will need either in order to obtain ore to 'seed' their farm, and therefore mine the Chlorophyte they farm.

Spread Mechanics

 * Chlorophyte will only naturally 'seed' (generating naturally, first as a single block replacing a random mud block) in Hardmode Underground Jungles (natural, artificial, or Clentaminator spread Jungles) but ore can be seeded practically anywhere underground.
 * Do not have any blocks of Ebonstone or Crimstone within three blocks of your farm. Both will convert mud into dirt, preventing Chlorophyte from growing. This will cause a struggle between the corrupted stone and the ore, leading to stagnation.
 * Chlorophyte will spread at Underground depth or below, but will spread much more at Cavern depth and below.
 * Chlorophyte does not need any kind of lighting to spread.
 * Chlorophyte does not seem to spread when all connected mud blocks are underwater (confirm?)
 * Chlorophyte has a spreading limit, checking a square area roughly centered around the ore tile selected to update.
 * Pre-1.3 the underground short-range maximum is 12 ore blocks in a 114 tile range (114x114 or an area of 12,996 tiles) and the long-range max is 56 ore blocks in a 284 tile range (284x284 or an area of 20,449 tiles).
 * Pre-1.3 the cavern short-range maximum is 24 ore blocks in a 76 tile range (76x76 or an area of 5,776 tiles) and the long-range max is approximately 111 ore blocks in a 190 tile range (190x190 or an area of 36,100 tiles).
 * In 1.3 the underground short-range maximum is 21 ore blocks in a 104 tile range (104x104 or an area of 10,816 tiles) and the long-range maximum is 66 ore blocks in a 127 tile range (127x127 or 16,129 tiles).
 * In 1.3 the cavern short-range maximum is 41 ore blocks in a 70 tile range (70x70 or an area of 4,900 tiles) and the long range maximum is approximately 131 ore blocks in a 170 tile range (170x170 or an area of 28,900 tiles).

Farming Methods

 * One method to farm Chlorophyte is to build a single square of mud with one Chlorophyte Ore block in the middle. A minimum sized square of 3x3 or 3x4 blocks will do, and a player should not build multiple squares close to each other, as this may hamper the farm's growth. One may also build multiple squares, as long as they are not within a 37 tile range (approximately 45 tile range before version 1.3) of each other, and the second image in the gallery below is an example of how it would look before version 1.3.
 * One may also instead create a single long horizontal or vertical one block strip with a single Chlorophyte Ore block in it, as an alternative method.
 * An optional place for a farm is the Underworld, as Chlorophyte will grow even to that depth. The underworld has large horizontal space and high vertical clearance. One does not need to clear space for a farm in the underworld, as the space already available can be used.
 * In 1.3 with the changes to Chlorophyte, these methods still work, but you can increase the size of the blocks to 6x6 or 6x7 (the 6x7 will leave one piece of mud un-converted). The spacing between farm regions should be no less than 37 tiles apart in most cases, or 38 tiles apart for 6x7 blocks to get maximum spread.
 * If you have a hellevator, you can just make occasional pit stops on the side and set up chlorophyte farming blocks with minimal extra digging.
