Can I dry red and white oak together? Will one stain the other?
I run a Nyle DH kiln and have done both at once, with no staining. Regulate your kiln based on the drying speed of white oak, since it is the slower drying of the two species.
In a perfect world you would only dry one species, thickness, and initial moisture content in your kiln at one time. I dry woods with similar drying rates and moisture contents together.
