I just harvested the compost box on my balcony, the little helpers are very happy:
I started it 4 years ago and use the humus for a little balcony chaos:
You can build one for yourself or buy the kit on the internet.
Either way, it’s fun playing in dirt, even for a grown person. You should try!

That looks like the top part of the compost bin. Is that some filling to keep it warm? Or something else?
That’s just a gimmick so you can sit on it. I bought the box from wurmkiste.at, they sell it with the cushion or plain. It gets very dirty over time so it’s not really worth the extra money.
