It started as an experiment. My goal was to create a Wabi Kusa with some left overs from my aquariums and to put it in a vase, and not like a classic ball. I didn't had any light left, so it grew on the window sill. I think it turned out good looking. I'm happy with the result with just the help of the sun.
I don't know why, but it looks like the quality of the picture is a little bit worse/blurred after the upload. I hope it looks normally, when you guys review it.
