Um, well, just an aside...cinnamon from your spice cabinet can be quite variable and studies have shown that it does not generally contain the active ingredient that works as a fungicide in strong enough concentration to really be effective. I would treat it with a real fungicide myself, after all, its an expensive thing, no? I use captan, but you can also use something like Physan20 which is bactericidal, virucidal, algaecide and fungicidal.
