It's going to be very mossy I hope!
Ahh that piece of wood, I really like it too, but I spent weeks doing WCs with in a bucket before the tannins came out, then it just leached mold and that started to get everywhere.
It did calm down but still came out of some holes on the side and I got fed up with it and threw it away!!
I thought I was being patient with it, but maybe not!!
