Automatic kelp farm
About this farm
A kelp farm mass-produces kelp, which makes excellent fuel once it's dried and packed into blocks. Kelp grows in water up to 26 blocks tall, and you cut it with pistons or by removing the water. Dried kelp (kelp smelted in a furnace) is a food that restores 1 hunger point, and one dried kelp block is enough fuel to smelt 20 items. The farm is compact: a column of water with kelp, a piston at the top that cuts the kelp, and hoppers under the water to collect it. An automatic system dries the kelp in furnaces fueled by dried kelp blocks, so the farm makes all the fuel it needs.
Key features
- Dried kelp is food, and dried kelp blocks are fuel
- Self-sufficient: the farm's own dried kelp blocks fuel its furnaces
- Dried kelp blocks: fuel for smelting 20 items each
- Kelp grows fast underwater
- Compact build

Tips and tricks
- Kelp grows 1 block at a time on random ticks, which makes it one of the faster-growing plants.
- Smelting kelp gives 0.1 XP per item, so connect the farm to an XP bank.
- 9 dried kelp = 1 dried kelp block (fuel for 20 items).
- For a self-sufficient farm, craft part of the dried kelp into fuel blocks and store the rest.
- You'll find kelp in oceans: bring one back to start the farm.
