Be sure to follow the rule before you head out.
Rule: You must post before you leave.
Out of pure curiosity does anyone know where "new growth fir" lumber is the typical building material? In the US most homes are built using Pine but that can't be true everywhere.
The "new growth" part is because the trees are harvested from farms as soon as they're big enough. This is as opposed to "old growth" where the trees are more mature and stronger.
Think veal versus beef in terms of texture
The maturity of a tree does not affect wood density. Density is determined by the stand density the year the ring is added along with factors such as soil moisture, temp etc. the inner rings will have the same density, whether the tree is harvested after a few years or after 200 years provided the tree stayed healthy.
