The timber are raw, I am cutting joinery so they are in my shop, which has a woodfire burning most of the time (and a 24" fan to make sure i have good circulation throughout. I'm not sure what the temp is but i am usually dressed in a t-shirt or sometimes a light sweater while working in there so its pretty warm.
PS
I did try bleach but the mold came back after about two weeks. Perhaps I'll increase the bleach to water ratio. I will also try the O. Acid.
