How long to dry timber?

[theflyingpig]

Here's a stack of treated boards I'm using to clad my workshop... I've cut a 15 degree angle onto one end (they are going to be vertical, "board on board").. retreated cut end with preservative, and am now drying out so as I can stain them some silly shade the missus chose....

My question - How long should I leave to dry?

Just for the ends? Less than a week if that store is left open.

May need less than 18% moisture, check with whoever makes the stain.

Thanks, I guess I need it dry enough to take the stain, and ideally not to shrink too much...
The boards certainly feel lighter already and they've only been stacked for 10 days....
