Hello, I just used your farm in my own world and I have a question. Bear with me, I don't speak german at all so I'm just using the images to understand your farm. At around 0:49 in your video, you show two sources of water and a source of lava in the middle. These 3 sources are separated by 2 blocks. When using your schema, these 2 blocks were not placed on my farm, I have two empty spaces there instead. What blocks are they so that I can add them manually ?
