The builder showcases the materials needed, noting that some are interchangeable. The construction begins by placing a double chest, followed by four hoppers feeding into it. Four furnaces are placed on top of these hoppers, with another set of four hoppers feeding into the furnaces from above. Solid blocks are then placed in front of and on top of these hoppers/furnaces for redstone placement.
Redstone dust is placed on the solid blocks in front of the furnaces. A lever is added to control the XP collection. Glass panes (or iron fence gates) are used to block water. Double chests are set up on both sides of the furnace array for item collection and alignment.
The core zero-tick mechanisms are built for both cactus and bamboo. This involves setting up sticky pistons, redstone torches, levers, and regular pistons to push sand blocks for rapid plant growth and harvesting. It's emphasized that this zero-tick system is specific to Java Edition. Observers and regular pistons are then added for the automatic harvesting of the plants.
Glass blocks are used for guiding the harvested items into water streams. A torch is added on the bamboo side to ensure sufficient light for growth. Bamboo and cactus are planted. Water streams are then placed to direct the harvested items towards the double chests, which lead into the furnaces.
Both the cactus and bamboo zero-tick mechanisms are activated. The bamboo serves as fuel, and the cactus is smelted. The system will initially only activate one furnace until the hoppers overflow, then it will distribute items to other furnaces. To collect XP, activated redstone dust locks the hoppers, allowing smelted items to accumulate in the furnaces. Deactivating the redstone releases the items and the stored XP.
The farm produces 1 XP per smelted cactus. The chest can act as a counter for XP. The video notes that this is a manual XP collection system but can be upgraded to be fully automatic with a dispenser. For even faster XP generation, a larger 18,000 XP/hour version is mentioned.
The video introduces a resource-friendly, fully automatic XP farm for Minecraft Java Edition. This farm generates 34,560 XP per real-life day and can run 24/7 if placed in loaded or spawn chunks. It allows players to reach level 30 from level 0 about 25 times per day.
