I got two from Recycle Now (bargainous price), and one has been fermenting for 2 weeks now, the time when it should be able to be added to your compost bin. However, when I peeked inside, it still looks like stuff with bran on! Surely I can't put that on my compost? It's been producing viscous golden liquid aplenty for the last couple of weeks, and there's a bloom of white mould on it, but the food is pretty much recognizable. Is that right?
