I'll show you how to build a Kelp Farm in Minecraft.
To do this, we will need these resources.
Dig a trench that is 9 blocks long.
And pour water into it.
And also plant kelp right here.
Next, we need to place an Observer right here.
Then skip 2 blocks and place another one.
And skip 2 blocks and place one more.
Now, lay down Redstone behind them.
And place blocks between them like this.
Next, place Pistons.
Enclose everything all around like this.
And place Stairs like this.
And pour water into them.
After that, raise the wall by one more block.
And pour one bucket of water right over here.
And also pour water right into here.
Now we can break the blocks right here like this.
And we can place a Chest.
And place a Hopper right here facing into the chest.
Now our farm is working.
As you can see, the kelp grows.
Then it gets harvested.
And it goes straight into the chest.
Thanks for watching. Goodbye.
