To maximize efficiency, treat Corundum farming like a vertical sugarcane or amethyst farm.
: Corundum clusters can grow up to four blocks tall, but only if they are placed on a Corundum Block of the same color. quark corundum farm
Observer → Repeater (2 ticks) → Redstone to piston. When corundum grows, piston extends, breaks the gem, retracts. To maximize efficiency, treat Corundum farming like a
: When a Corundum block is capable of growing, it emits small sparkling particles. If you "wax" the block (using honeycombs), it stops producing particles and ceases growth, which is useful for permanent decorations. To maximize efficiency
: In addition to full blocks, small crystal clusters can also sprout on the sides or top of the main Corundum pillar. Setting Up Your Farm
