Why these same 6 X 2's weigh different?


I recently bought 4 pieces of 6 X 2 lumber, 10' long. I've noticed that 2 of them are much heavier than the other two, even though they are the same dimensions, and both are douglas fir.
The heavier pieces look older and whiter. The lighter pieces are redder and look newer, cleaner.
Does anyone know why this should be the case?

Thanks

Old growth wood of a given species is denser(tighter rings) than farmed wood of the same species.

I'd think heartwood vs. sapwood (different parts of trees) could have different densities as well.

Also moisture content can play a big role in weight.

ain't that the truth.

nearly all the products with any real consistency and predictability are man-made/engineered

but natural stuff has it's own beauty

The new ones are lighter because they are drier. As 2x6's are kiln dried, the moisture is removed to stabilize the wood from twisting and warping later. 15-19%, I think... The older ones have absorbed moisture from the air and gotten heavier because of the water as they have been out of the kiln longer.
My 2 cents....
