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 have a spreading limit
 * Pre-1.3 the underground short-range maximum is 12 ore blocks in a 57 tile range (57x57 or an area of 3249) and the long-range max is 55 ore blocks in a 143 tile range (143x143 or an area of 20449)
 * Pre-1.3 the cavern short-range maximum is 24 ore blocks in a 38 tile range (38x38 or an area of 1444) and the long-range max is 110 ore blocks in a 95 tile range (95x95 or an area of 9025)
 * This means, for example, in a 38x38 sized farm, no more Chlorophyte will spread if there is 24 Chlorophyte
 * Post-1.3 the smaller range appears to have been removed and the cap in the cavern/underworld layers has been changed to 41 ore blocks in a 95 tile range.

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 38 tile range of each other, and the second image in the gallery below is an example.
 * 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 should also be 92 tiles, not 38.
