Six months ago I cut 1000 bd ft of honey locust into 8/4 boards, half of which went into my DH kiln and dried to 6% at a very slow pace. The other half has been stickered for air drying. All the logs were coated with AnchorSeal immediately after felling.
The wood from the kiln has considerable checking (70% firewood). Thinking I had somehow screwed up the drying process, I looked at the air dried HL (stacked and stickered in a covered building; little air movement; winter temps). It is currently at 24% MC. Oddly, the air dried HL looks worse than the kiln dried HL. The following pictures are of the air dried HL. The checking which runs from end to end seems to be shallow; such that I could plane off .25" from each side and get below the checking. (The same defects on my kiln dried HL run far deeper.)
The tree was very straight; there did not appear to be any obvious stress; all the logs came from the trunk with no branching. Am I losing this load because I had it cut 8/4 instead of 4/4 or 5/4? Since the air dried stock is as damaged or more damaged than the KD stock, I don't think it could be the schedule. Maybe just the luck of the draw?

From contributor W:
From your photos, I would say you need to slow the drying down. 8/4, in many species, is a little tricky because in has to dry very slowly. The photos even show honeycomb because of the fast drying, if that end grain photo was just cut.
