Tutorials/Glow lichen farming
Glow Lichen farming is the process of producing and obtaining large quantities of glow lichen.
Preparation and reasoning
Find at least 1 Glow Lichen in a cave. It can be found in all the types of caves and is naturally generated on stone, andesite, diorite, granite, calcite, tuff, deepslate and dripstone blocks underground and harvested with shears.
Glow lichen can be bonemealed manually or via a Dispenser. It can only be harvested via Shears and if broken with other tools, even with Silk Touch will have the lichen drop nothing. Efficiency does not affect breaking speed.
Because it can be bonemealed by a dispenser, and it will always go to an open block off one of the four sides, it can easily be autofarmed by rapid fire bonmealing it from a dispenser, and blocking off all available places to grow, except one, and monitoring that block with an observer connected to a dispenser with shears. The drops can then be collected by a minecart hopper below the block that the harvested plant is on.
