Watch ↗About this farm
A fully automatic kelp farm that harvests kelp for dried kelp, fuel, or food using the classic observer-and-piston mechanism that breaks the stalk as it grows. Compact and low on redstone complexity, it can run AFK once set up. Verified current for Minecraft 1.21+; the harvesting mechanic is identical across Java and Bedrock.
