At the moment I am adding no bran at all and just using it as a kitchen compost box but that is mainly because we have been in turmoil here - and it works fine just for usual peelings and teabags/coffee grounds. But yes, I found I was going through the bran quickly too. Now the weather is milder and I haven't got to worry about the second box freezing solid outside the back door I will re-instate the bokashi bit - but take your tip about using less bran, Alison.

Incidentally, does anyone know why you can't put teabags in it? They rot down OK in my compost heap, so that bit really surprised me.

Woohoo, this post turned me into a sprouter (as it were)! Go me!
